WEBVTT - CRISPR and the Genetic Astronaut

0:00:03.080 --> 0:00:06.199
<v Speaker 1>Welcome to Stuff to Blow your Mind from how Stuffworks

0:00:06.200 --> 0:00:14.680
<v Speaker 1>dot com. Hey you welcome to Stuff to Blow your Mind.

0:00:14.720 --> 0:00:17.320
<v Speaker 1>My name is Robert Lamb and I'm Joe McCormick and

0:00:17.400 --> 0:00:19.800
<v Speaker 1>Robert Today. I know you wanted to talk about something

0:00:19.840 --> 0:00:23.520
<v Speaker 1>that you saw at a panel at the World Science Festival,

0:00:25.320 --> 0:00:28.280
<v Speaker 1>and this topic was something that I hadn't really thought

0:00:28.320 --> 0:00:30.080
<v Speaker 1>all that much about. Maybe maybe it'd come up a

0:00:30.160 --> 0:00:35.000
<v Speaker 1>little bit before. But it's uh, GMOs and not GMO

0:00:35.200 --> 0:00:41.120
<v Speaker 1>wheat or GMO corn or GMO mosquitoes, but GMO astronauts.

0:00:41.760 --> 0:00:45.080
<v Speaker 1>That's right. This Uh the panel that I ended up attending.

0:00:45.159 --> 0:00:48.040
<v Speaker 1>This was one of their salons at World Science Festival,

0:00:48.320 --> 0:00:51.280
<v Speaker 1>Evolution Beyond Earth. It was. It was one of the

0:00:51.360 --> 0:00:55.080
<v Speaker 1>highlights for me because it basically revolved around a discussion

0:00:55.400 --> 0:00:59.680
<v Speaker 1>of genetically modifying humans for space exploration. And this is

0:00:59.680 --> 0:01:01.400
<v Speaker 1>a great topic because it touches on some stuff that

0:01:01.440 --> 0:01:06.160
<v Speaker 1>we've covered before. The idea of augmenting humans for space,

0:01:06.640 --> 0:01:09.080
<v Speaker 1>uh is an idea that goes back decades, and we'll

0:01:09.080 --> 0:01:12.679
<v Speaker 1>get into that. And it also touches upon just genetically

0:01:12.720 --> 0:01:17.280
<v Speaker 1>modifying organisms in general and the crisper technology, something that

0:01:17.560 --> 0:01:19.920
<v Speaker 1>we've been we've wanted to talk about on the show

0:01:19.959 --> 0:01:23.440
<v Speaker 1>for years, and I feel like this gives us a

0:01:23.520 --> 0:01:28.640
<v Speaker 1>proper science fiction flavored excuse to discuss it within uh,

0:01:28.720 --> 0:01:31.720
<v Speaker 1>you know, a particular set of parameters. Okay, So today

0:01:31.760 --> 0:01:33.759
<v Speaker 1>we are going to be doing our best to try

0:01:33.760 --> 0:01:37.679
<v Speaker 1>to give a simple, straightforward explanation what the Crisper gene

0:01:37.800 --> 0:01:41.000
<v Speaker 1>editing process is and what it does, but also to

0:01:41.480 --> 0:01:43.479
<v Speaker 1>uh explore a little bit of what they talk about

0:01:43.480 --> 0:01:47.680
<v Speaker 1>in this panel about genetically modifying astronauts and ask should

0:01:47.680 --> 0:01:50.720
<v Speaker 1>we do it? Should we make our spacemen and space

0:01:50.760 --> 0:01:55.400
<v Speaker 1>women of tomorrow creatures of the gene scalpel? Well, if

0:01:55.400 --> 0:01:58.920
<v Speaker 1>you phrase it like that, um, I mean, really it

0:01:58.920 --> 0:02:01.160
<v Speaker 1>seems like a reasonable proper position, doesn't it. I mean,

0:02:01.200 --> 0:02:05.000
<v Speaker 1>when you consider I want you could consider the options. Okay,

0:02:05.000 --> 0:02:09.280
<v Speaker 1>you could potentially terraform another world. You could you could

0:02:09.320 --> 0:02:14.080
<v Speaker 1>strain to bring a particular human environment into space. You know, basically,

0:02:14.240 --> 0:02:17.880
<v Speaker 1>can a canned version of Earth throw it into space

0:02:17.880 --> 0:02:20.880
<v Speaker 1>and let people live in that? Or perhaps you can

0:02:20.919 --> 0:02:23.720
<v Speaker 1>just change what people are. You can make you can

0:02:23.760 --> 0:02:28.400
<v Speaker 1>either adapt people to existing environments beyond Earth or tweak

0:02:28.480 --> 0:02:30.280
<v Speaker 1>them in such a way that you're not having to

0:02:30.360 --> 0:02:35.760
<v Speaker 1>bend over backwards to create an environment for them beyond Earth.

0:02:37.160 --> 0:02:39.160
<v Speaker 1>And this is this is an idea that is resonated

0:02:39.200 --> 0:02:42.600
<v Speaker 1>in science fiction for some time. A few different examples

0:02:42.600 --> 0:02:44.359
<v Speaker 1>come to my mind. I don't I don't know if

0:02:44.840 --> 0:02:47.600
<v Speaker 1>if any of these, uh, we're knocking around your head

0:02:47.639 --> 0:02:50.120
<v Speaker 1>as well, or if you have your own examples to

0:02:50.120 --> 0:02:53.360
<v Speaker 1>to discuss. No, let's hit yours man, all right? Well? Um.

0:02:53.639 --> 0:02:56.919
<v Speaker 1>The first is a novel by a Clifford D. Simic,

0:02:57.560 --> 0:03:01.680
<v Speaker 1>who is a kind of a legend and science fiction circles.

0:03:01.760 --> 0:03:04.560
<v Speaker 1>He was very prolific. He is probably best known for

0:03:04.600 --> 0:03:07.440
<v Speaker 1>a collection of short stories, but he wrote titled City.

0:03:08.600 --> 0:03:11.600
<v Speaker 1>One of the tales I think involves um speaking dogs,

0:03:11.720 --> 0:03:16.320
<v Speaker 1>like a race of intelligence talking dogs that wait. Telepathic

0:03:16.360 --> 0:03:18.560
<v Speaker 1>dogs are just like saying words out loud with their

0:03:18.600 --> 0:03:23.240
<v Speaker 1>dog mouths. I think they're they're speaking, but I'm not certainly,

0:03:23.240 --> 0:03:25.840
<v Speaker 1>because there's not one that I've read. One book of

0:03:25.880 --> 0:03:28.720
<v Speaker 1>his that I have read though, is N sevens The

0:03:28.760 --> 0:03:34.120
<v Speaker 1>Werewolf Principle. And this is this is a great book

0:03:34.120 --> 0:03:37.400
<v Speaker 1>in a number of ways because essentially, I I don't

0:03:37.440 --> 0:03:40.600
<v Speaker 1>know the origin of it, but it feels like someone said, hey, Clifford,

0:03:40.720 --> 0:03:43.480
<v Speaker 1>can you write a space werewolf book for us. I

0:03:43.520 --> 0:03:46.480
<v Speaker 1>think that's something people would like to read, and who wouldn't.

0:03:47.240 --> 0:03:50.440
<v Speaker 1>But he does a fantastic spin on it that is

0:03:50.480 --> 0:03:57.200
<v Speaker 1>just so thoroughly, so thoroughly late sixties, early seventies, you know,

0:03:57.680 --> 0:04:01.720
<v Speaker 1>science fiction. Uh So, it's a wonderfully weird novel in

0:04:01.760 --> 0:04:05.240
<v Speaker 1>which a human space traveler is augmented to rapidly adapt

0:04:05.240 --> 0:04:08.600
<v Speaker 1>to alien worlds. He's sort of an android designed to

0:04:08.720 --> 0:04:12.520
<v Speaker 1>scan and mimic alien species for research purposes. He's one

0:04:12.520 --> 0:04:16.120
<v Speaker 1>of only two constructed, and he's sent out to alien worlds,

0:04:16.200 --> 0:04:19.000
<v Speaker 1>uh two hundred years ago. He visits a number of

0:04:19.040 --> 0:04:21.719
<v Speaker 1>these planets and then he returns to Earth and begins

0:04:21.720 --> 0:04:27.120
<v Speaker 1>to experience transformations into these into certain certain monstrous forms.

0:04:27.320 --> 0:04:31.560
<v Speaker 1>He's having an identity crisis. And in the background to

0:04:31.640 --> 0:04:34.960
<v Speaker 1>all this, the the the the earth setting that all

0:04:35.000 --> 0:04:38.360
<v Speaker 1>of this has taken place on Invote includes flying houses

0:04:39.040 --> 0:04:41.679
<v Speaker 1>because humans have these, you know, these space age houses.

0:04:41.680 --> 0:04:43.120
<v Speaker 1>Why I stay in one spot when you can have

0:04:43.160 --> 0:04:46.040
<v Speaker 1>your house moved from spot to spot. And also the

0:04:46.080 --> 0:04:50.080
<v Speaker 1>woods are teeming with brownies or maybe not teaming. Teeming

0:04:50.120 --> 0:04:52.400
<v Speaker 1>is not the right word. But we've reached the point

0:04:52.480 --> 0:04:55.000
<v Speaker 1>as a human species to realize. Oh yeah, most of

0:04:55.000 --> 0:04:57.840
<v Speaker 1>the mythical creatures that we taught, we spoke about and

0:04:57.839 --> 0:05:01.200
<v Speaker 1>sing songs about, they weren't real. Up for brownies, brownies

0:05:01.200 --> 0:05:05.039
<v Speaker 1>were real. Are brownies like fairies? Yeah, they're just like

0:05:05.080 --> 0:05:07.719
<v Speaker 1>a race of fairies and they live in the Pope Woods.

0:05:07.760 --> 0:05:10.360
<v Speaker 1>And I don't I don't recall to what extent they

0:05:10.400 --> 0:05:14.279
<v Speaker 1>actually play a part in the plot of the werewolf principle,

0:05:14.440 --> 0:05:17.960
<v Speaker 1>but just that they're there because the world its own

0:05:18.040 --> 0:05:20.400
<v Speaker 1>unique stent. You know. I'm glad to hear that there's

0:05:20.440 --> 0:05:24.200
<v Speaker 1>a space werewolf novel because that's something that there could

0:05:24.240 --> 0:05:26.640
<v Speaker 1>stand to be plenty of. I'm waiting for the Space

0:05:26.720 --> 0:05:30.760
<v Speaker 1>Mummy novel. When does that happen? Well, there was that film.

0:05:31.279 --> 0:05:34.000
<v Speaker 1>I forget the title of it or the titles, but

0:05:34.080 --> 0:05:36.719
<v Speaker 1>it was. It was featured on Mystery Sentence. Theater three

0:05:36.720 --> 0:05:41.600
<v Speaker 1>thousand had an ancient astronauts money is like, was it

0:05:42.279 --> 0:05:45.680
<v Speaker 1>the Frankenstein and the Aztec Mummy? No, but maybe that

0:05:45.800 --> 0:05:49.400
<v Speaker 1>was also space Mummy. But this one was like visitor

0:05:49.520 --> 0:05:53.000
<v Speaker 1>from another world or something to that effect. No, I

0:05:53.040 --> 0:05:55.560
<v Speaker 1>don't know what that is. Well, anyway, I will agree

0:05:55.600 --> 0:06:00.320
<v Speaker 1>that it is an under utilized sub genre, the space mummy.

0:06:00.440 --> 0:06:02.400
<v Speaker 1>That's what we should be going back to. Ye, So

0:06:02.440 --> 0:06:04.839
<v Speaker 1>if you're in the middle of writing a space vampire novel,

0:06:05.320 --> 0:06:07.440
<v Speaker 1>give it up, just put it on hold. Give us

0:06:07.440 --> 0:06:10.000
<v Speaker 1>space mummies first. Yeah, and then the sequel can be

0:06:10.040 --> 0:06:13.679
<v Speaker 1>space mummies versus space werewolves. Now, another sci fi property

0:06:13.680 --> 0:06:16.239
<v Speaker 1>that comes to mind is a two thousand nine film

0:06:16.440 --> 0:06:18.160
<v Speaker 1>that I know some people did not enjoy, but I

0:06:18.160 --> 0:06:21.960
<v Speaker 1>actually really enjoyed this one to two thousand nine Pandorum

0:06:21.960 --> 0:06:25.360
<v Speaker 1>like some things about it. Yeah, I I embraced the

0:06:25.400 --> 0:06:29.560
<v Speaker 1>mixed review. I embraced all of it. This is the

0:06:29.560 --> 0:06:32.719
<v Speaker 1>one that had Dennis Quaid in it. It did. It's yeah,

0:06:32.920 --> 0:06:36.080
<v Speaker 1>I will say it's not one of Dennis Quaids finer performances.

0:06:36.120 --> 0:06:40.200
<v Speaker 1>It's no enemy mine. But the plot, the look at

0:06:40.200 --> 0:06:42.000
<v Speaker 1>the film I thought was great and the plot was

0:06:42.080 --> 0:06:44.280
<v Speaker 1>kind of cool. They so they're a colonists aboard and

0:06:44.360 --> 0:06:49.680
<v Speaker 1>interstellar arc named the Elysium, and the colonists are augmented

0:06:49.680 --> 0:06:53.440
<v Speaker 1>to rapidly adapt to the environment of their destination exoplanet,

0:06:53.480 --> 0:06:58.000
<v Speaker 1>which is a world called Tennis. But of course, something

0:06:58.040 --> 0:07:00.280
<v Speaker 1>goes horribly wrong and a portion of the crew wakes

0:07:00.360 --> 0:07:03.800
<v Speaker 1>up early, they go a little crazy, and their descendants

0:07:04.040 --> 0:07:07.920
<v Speaker 1>rapidly adapt to the environment of the spaceship and they

0:07:08.120 --> 0:07:12.080
<v Speaker 1>become the essentially become a race of cannibal mutant trog lafuna.

0:07:12.240 --> 0:07:15.760
<v Speaker 1>It's kind of like the descent in a spaceship instead

0:07:15.760 --> 0:07:18.400
<v Speaker 1>of a cave. Yes, yeah, I think that's a that's

0:07:18.480 --> 0:07:23.160
<v Speaker 1>a fair assessment, and it also reminds me a bit

0:07:23.200 --> 0:07:26.280
<v Speaker 1>of a movie that came out of along the same time, uh,

0:07:26.400 --> 0:07:29.080
<v Speaker 1>known as eden Log. Did you happen to see this? No?

0:07:29.200 --> 0:07:32.160
<v Speaker 1>I don't think so. Eden Log is is hauntingly familiar.

0:07:32.280 --> 0:07:36.960
<v Speaker 1>It's like a more artistic French reflection of the same film.

0:07:37.720 --> 0:07:40.960
<v Speaker 1>So I would say, if if anyone out there enjoyed Pandoram,

0:07:41.840 --> 0:07:44.600
<v Speaker 1>go see eden Log, or if you enjoyed parts of Pandorum,

0:07:45.240 --> 0:07:48.120
<v Speaker 1>go watch eden Log. You probably won't understand what's happening.

0:07:48.120 --> 0:07:49.880
<v Speaker 1>But when has that ever gotten in the in the

0:07:49.920 --> 0:07:52.280
<v Speaker 1>way of a good good time in a science fiction movie.

0:07:53.920 --> 0:07:57.720
<v Speaker 1>I should also point out that in Dan Simon's Hyperion novels,

0:07:57.720 --> 0:08:00.480
<v Speaker 1>you have the the Alsters, humans who have adapted to

0:08:00.560 --> 0:08:05.080
<v Speaker 1>life in space, granted suited and within ships, but still

0:08:05.520 --> 0:08:07.800
<v Speaker 1>uh that they've been able to adapt due to extensive

0:08:07.840 --> 0:08:12.200
<v Speaker 1>genetic self manipulation. And then the Expanse series based on

0:08:12.240 --> 0:08:15.600
<v Speaker 1>the books by James S. A. Corey. You see belters

0:08:15.640 --> 0:08:21.560
<v Speaker 1>who are who have adapted to to life on ships

0:08:21.640 --> 0:08:24.640
<v Speaker 1>on the sort of the the outer limits of human

0:08:24.680 --> 0:08:27.280
<v Speaker 1>habitation in the Solar System. Yeah, this is probably the

0:08:27.320 --> 0:08:29.680
<v Speaker 1>example I would have mentioned if I was going to

0:08:29.760 --> 0:08:33.760
<v Speaker 1>bring up genetic adaptation to space conditions, because obviously living

0:08:33.800 --> 0:08:37.520
<v Speaker 1>in lower gravity environments, this would be problematic for humans

0:08:37.520 --> 0:08:40.479
<v Speaker 1>who have been tailored by billions of years of evolution

0:08:40.559 --> 0:08:44.160
<v Speaker 1>to survive on a Earth gravity world. If you're out

0:08:44.160 --> 0:08:46.640
<v Speaker 1>in a small gravity world, you just probably need a

0:08:46.640 --> 0:08:51.640
<v Speaker 1>different body, right, And so these differently adapted creatures. There's

0:08:51.760 --> 0:08:55.760
<v Speaker 1>this one scene I remember in the Expanse of gravity

0:08:55.800 --> 0:08:58.960
<v Speaker 1>torture Belters being brought back to Earth and tortured with

0:08:59.000 --> 0:09:03.000
<v Speaker 1>Earth gravity. Yeah, just the the the the act of

0:09:03.000 --> 0:09:07.120
<v Speaker 1>of living on a higher gravity world is torment to them.

0:09:07.679 --> 0:09:10.440
<v Speaker 1>And that kind of underlines the reverse challenges of taking

0:09:10.600 --> 0:09:13.440
<v Speaker 1>your You're taking a creature and expecting it to live

0:09:13.880 --> 0:09:17.480
<v Speaker 1>in an environment that is tortured to them, that they

0:09:17.240 --> 0:09:20.000
<v Speaker 1>that they just simply have not evolved to cope with.

0:09:21.200 --> 0:09:23.880
<v Speaker 1>So the panel that I that I attended. It was

0:09:23.960 --> 0:09:27.920
<v Speaker 1>moderated by neuroscientist Stuart fire Stain, and the panelists were

0:09:28.160 --> 0:09:32.800
<v Speaker 1>geneticist Chris Mason geneticist Ting Wu who as a sort

0:09:32.800 --> 0:09:36.520
<v Speaker 1>of trivia on Teing Woo. She is the wife of

0:09:36.600 --> 0:09:41.800
<v Speaker 1>noted geneticist Georgia m. Church and also astrobiologist Caleb Sharf.

0:09:42.679 --> 0:09:45.880
<v Speaker 1>So we we don't even have to consider the challenges

0:09:45.920 --> 0:09:49.839
<v Speaker 1>of an alien planet to consider the the benefits or

0:09:49.880 --> 0:09:53.440
<v Speaker 1>the potential benefits of of altering humans for space travel.

0:09:53.600 --> 0:09:56.560
<v Speaker 1>In fact, you might say space travel itself is the

0:09:56.640 --> 0:09:59.920
<v Speaker 1>harshest possible environment, maybe even more so than another plan

0:10:00.000 --> 0:10:01.880
<v Speaker 1>And I guess depending on what the planet is like,

0:10:02.000 --> 0:10:04.280
<v Speaker 1>because on another planet you'd at least expect to have

0:10:04.360 --> 0:10:08.320
<v Speaker 1>some gravity, right, or you can only assume there will

0:10:08.320 --> 0:10:12.040
<v Speaker 1>be like some level of robust radiation shielding, either in

0:10:12.080 --> 0:10:16.040
<v Speaker 1>the form of a of a naturally occurring magnetosphere or

0:10:16.080 --> 0:10:20.959
<v Speaker 1>like hopefully a substantial underground base or whatever. Your your

0:10:20.960 --> 0:10:23.679
<v Speaker 1>off world colonies gonna consist of an atmosphere and an

0:10:23.679 --> 0:10:27.280
<v Speaker 1>atmosphere which is also gonna entail a certain amount of

0:10:27.360 --> 0:10:31.839
<v Speaker 1>radiation shielding. But your your your tin can, your your

0:10:31.840 --> 0:10:35.880
<v Speaker 1>generation ship sailing across the space. Sailing across interstellar space,

0:10:35.960 --> 0:10:39.240
<v Speaker 1>even that's going to be a different proposition. Unless you're

0:10:39.280 --> 0:10:42.360
<v Speaker 1>going to a comet or small asteroid. The ship is

0:10:42.400 --> 0:10:46.320
<v Speaker 1>probably a harsher environment and and uh and probably a

0:10:46.360 --> 0:10:50.280
<v Speaker 1>long journey. Oh. An important point that that that the

0:10:50.320 --> 0:10:54.320
<v Speaker 1>moderator Stewart Finstein made in this is that humans have

0:10:54.480 --> 0:10:57.679
<v Speaker 1>proven incredibly adaptable here on Earth. And I think this

0:10:57.800 --> 0:10:59.680
<v Speaker 1>leads into this idea that we should be able to

0:10:59.679 --> 0:11:03.120
<v Speaker 1>survive anywhere. Right we live all over the world. We can,

0:11:03.320 --> 0:11:08.160
<v Speaker 1>we can sustain ourselves in pretty harsh conditions. And yet, um,

0:11:08.240 --> 0:11:10.640
<v Speaker 1>even though we've become a global species, even though we're

0:11:10.679 --> 0:11:16.040
<v Speaker 1>considering this leap uh into becoming an interplanetary species species,

0:11:16.280 --> 0:11:20.320
<v Speaker 1>we entertain quote a migration to a place that has

0:11:20.400 --> 0:11:24.360
<v Speaker 1>never impacted our evolution in any way. That's a really

0:11:24.360 --> 0:11:28.440
<v Speaker 1>good point. I mean, yeah, there's there's just been zero

0:11:28.559 --> 0:11:33.760
<v Speaker 1>input whatsoever of for example, zero you know, microgravity conditions

0:11:33.840 --> 0:11:36.600
<v Speaker 1>on on the evolution of any life form on Earth,

0:11:37.200 --> 0:11:41.480
<v Speaker 1>no precedent whatsoever. So on the other hand, so on

0:11:41.480 --> 0:11:43.600
<v Speaker 1>one hand, you can say that place is not for us,

0:11:44.120 --> 0:11:46.000
<v Speaker 1>the space is horrible, why would you want to go there?

0:11:46.360 --> 0:11:49.320
<v Speaker 1>But there are plenty that argue that, hey, we need

0:11:49.360 --> 0:11:53.160
<v Speaker 1>to figure it out, that that life beyond Earth is

0:11:54.080 --> 0:11:57.000
<v Speaker 1>vital to the long term survival of the human race.

0:11:57.240 --> 0:12:00.520
<v Speaker 1>That if we're going to continue to exist long term,

0:12:00.520 --> 0:12:04.160
<v Speaker 1>we have to exist places other than this world. Right.

0:12:04.720 --> 0:12:07.760
<v Speaker 1>We can debate what the number is, but the natural

0:12:07.760 --> 0:12:11.320
<v Speaker 1>ecology of Earth, or even the augmented ecology of Earth,

0:12:11.400 --> 0:12:14.679
<v Speaker 1>does have some kind of natural carrying capacity. There's some

0:12:14.840 --> 0:12:18.280
<v Speaker 1>maximum number of humans that it can sustain in terms

0:12:18.280 --> 0:12:23.640
<v Speaker 1>of giving them clean air to breathe, freshwater, food space

0:12:23.720 --> 0:12:26.200
<v Speaker 1>to live, all those kinds of things. At some point,

0:12:26.280 --> 0:12:28.760
<v Speaker 1>we we will run out of that if we keep multiplying,

0:12:29.040 --> 0:12:32.480
<v Speaker 1>and of course there are there there are hard stops

0:12:32.880 --> 0:12:35.840
<v Speaker 1>for just the habitability of Earth in the long term

0:12:35.880 --> 0:12:37.960
<v Speaker 1>future as well. Yeah, at some point the sun will

0:12:38.000 --> 0:12:41.440
<v Speaker 1>sort of increase in size. That's not so great for

0:12:41.520 --> 0:12:45.480
<v Speaker 1>the surface dwellers of the Earth. Yeah, and uh, And

0:12:45.520 --> 0:12:47.440
<v Speaker 1>then there's there's another argument to be made here, and

0:12:47.480 --> 0:12:51.319
<v Speaker 1>this is the one that that the astrobiologist Caleb sharfmin

0:12:51.400 --> 0:12:53.640
<v Speaker 1>and the talk he said, he said a human exploration

0:12:53.720 --> 0:12:57.679
<v Speaker 1>remains the best option for exploration, that robots can only

0:12:57.679 --> 0:13:00.120
<v Speaker 1>get us so far, and that there's and the this

0:13:00.200 --> 0:13:03.160
<v Speaker 1>you kind of get into a more I guess, philosophical

0:13:03.240 --> 0:13:06.720
<v Speaker 1>argument for exploration when you're saying that, yeah, you can

0:13:06.760 --> 0:13:10.000
<v Speaker 1>send robots, that you can send probes out. Uh, we can.

0:13:10.240 --> 0:13:12.880
<v Speaker 1>We can move a joystick and then move a robotic

0:13:13.000 --> 0:13:15.839
<v Speaker 1>arm in another world with some degree of lag time.

0:13:16.400 --> 0:13:20.320
<v Speaker 1>But are we losing something? Is there something? Is there

0:13:20.400 --> 0:13:25.040
<v Speaker 1>something lost in not having actual human exploration. Sure you

0:13:25.080 --> 0:13:28.720
<v Speaker 1>can make that argument. I mean, I think I'm of

0:13:28.760 --> 0:13:31.720
<v Speaker 1>the opinion that robotic exploration can get us a lot

0:13:31.760 --> 0:13:34.880
<v Speaker 1>of what we need. We can get some good research results,

0:13:35.040 --> 0:13:38.640
<v Speaker 1>we can reduce the risk of human death and injury,

0:13:38.679 --> 0:13:42.920
<v Speaker 1>and reduce the risk of cross contamination of environments and

0:13:42.920 --> 0:13:44.360
<v Speaker 1>and all that kind of stuff. You can do a

0:13:44.400 --> 0:13:47.160
<v Speaker 1>lot with robots. But there are some things that humans

0:13:47.160 --> 0:13:50.319
<v Speaker 1>are sort of unique providers of. One is on site ingenuity.

0:13:51.600 --> 0:13:54.320
<v Speaker 1>Robots at this point do not have the kind of

0:13:54.400 --> 0:13:59.640
<v Speaker 1>intelligence and ingenuity and creativity that a human astronaut would have.

0:14:00.080 --> 0:14:02.760
<v Speaker 1>If you were trying to trying to not just say,

0:14:02.840 --> 0:14:05.760
<v Speaker 1>do a few specific tests on the surface of Mars,

0:14:05.800 --> 0:14:10.400
<v Speaker 1>but to create a robust research environment on a faraway

0:14:10.520 --> 0:14:14.400
<v Speaker 1>planet that makes sense. But then also on top of that,

0:14:15.360 --> 0:14:18.400
<v Speaker 1>humans have inspiration potential for the rest of humanity in

0:14:18.440 --> 0:14:21.320
<v Speaker 1>a way that robots don't. Not to say it's not

0:14:21.440 --> 0:14:25.160
<v Speaker 1>inspiring to see the Curiosity rover, for example, moving around

0:14:25.160 --> 0:14:27.640
<v Speaker 1>on the surface of Mars. But you can't deny there

0:14:27.640 --> 0:14:30.280
<v Speaker 1>will be a very different kind of effect when there

0:14:30.280 --> 0:14:33.520
<v Speaker 1>are human feet on the soil of Marsh, no doubt.

0:14:34.760 --> 0:14:37.680
<v Speaker 1>And so we end up and then asking the question, well,

0:14:37.720 --> 0:14:39.080
<v Speaker 1>how is this going to happen? How are we going

0:14:39.160 --> 0:14:42.840
<v Speaker 1>to pull it off? And indeed, what changes might we

0:14:42.920 --> 0:14:46.160
<v Speaker 1>want or need to make to the human body to

0:14:46.440 --> 0:14:50.600
<v Speaker 1>enable those feet uh, those footsteps to actually take place

0:14:50.600 --> 0:14:52.760
<v Speaker 1>on Mars. Well, I know one answer is we gotta

0:14:52.840 --> 0:14:56.520
<v Speaker 1>got to replace these hands with crab claws. When are

0:14:56.520 --> 0:15:00.840
<v Speaker 1>we finally going to get our clause? Robert, Well, I

0:15:00.880 --> 0:15:03.280
<v Speaker 1>mean maybe there's an our baby steps though, right, Because

0:15:04.520 --> 0:15:07.480
<v Speaker 1>if our knowledge of GMOs has thought us anything thus far,

0:15:07.760 --> 0:15:09.880
<v Speaker 1>is that people are are going to be resistant to

0:15:09.920 --> 0:15:13.320
<v Speaker 1>the idea of like rapid change. Right, They're not gonna

0:15:13.360 --> 0:15:15.880
<v Speaker 1>go for crab clouds right off the bat, but maybe

0:15:15.880 --> 0:15:20.520
<v Speaker 1>more subtle changes at any rate. Genesis Chris Mason says

0:15:20.560 --> 0:15:23.840
<v Speaker 1>that we need to consider a five hundred year lab plan.

0:15:24.600 --> 0:15:27.320
<v Speaker 1>So a multi stage plan to advance our understanding of

0:15:27.320 --> 0:15:30.080
<v Speaker 1>the human genome, figure out exactly what we can tweak

0:15:30.200 --> 0:15:32.920
<v Speaker 1>where we need to tweak it to adapt humans to

0:15:33.120 --> 0:15:37.440
<v Speaker 1>better Uh. For instance, a thrive on a trip to

0:15:37.520 --> 0:15:42.360
<v Speaker 1>Mars and then the subsequent stay on Mars, a subsequent

0:15:42.400 --> 0:15:45.280
<v Speaker 1>colonization of Mars. So five dred years that's a pretty

0:15:45.280 --> 0:15:48.240
<v Speaker 1>slow ascent, and I can see some benefits to that.

0:15:48.400 --> 0:15:50.640
<v Speaker 1>Number one, that gives the technology plenty of time to

0:15:50.680 --> 0:15:52.640
<v Speaker 1>get there. But number two, it's what you were talking

0:15:52.680 --> 0:15:56.440
<v Speaker 1>about with baby steps and acclimatizing people. Yeah, it would

0:15:56.480 --> 0:15:59.760
<v Speaker 1>give people in general a chance to say, okay, this

0:15:59.840 --> 0:16:03.360
<v Speaker 1>is fine, you know, because each generation the changes would

0:16:03.360 --> 0:16:05.720
<v Speaker 1>be small. Yeah, so hopefully by the time crab class

0:16:05.760 --> 0:16:08.360
<v Speaker 1>came along, everyone would be cool with it. And it's

0:16:08.440 --> 0:16:10.480
<v Speaker 1>but it's also it's easy to say, well this that

0:16:10.600 --> 0:16:15.480
<v Speaker 1>this sucks is an option because five years we're not

0:16:15.480 --> 0:16:17.160
<v Speaker 1>going to be around to to see the fruits of

0:16:17.160 --> 0:16:21.120
<v Speaker 1>that labor. But it also really plays to humanity strengths

0:16:21.480 --> 0:16:27.920
<v Speaker 1>because no matter granted, we we often suffer for our

0:16:27.960 --> 0:16:32.960
<v Speaker 1>ability to not um not calculate things long term, but

0:16:33.080 --> 0:16:34.760
<v Speaker 1>yet at the at the same time, we do have

0:16:34.840 --> 0:16:38.640
<v Speaker 1>a unique ability to plan beyond our own lifespan. So

0:16:38.680 --> 0:16:42.320
<v Speaker 1>it's it's kind of a it's a special magic that

0:16:42.320 --> 0:16:45.760
<v Speaker 1>that other organisms do not have. Even if it's a

0:16:46.120 --> 0:16:50.480
<v Speaker 1>one that we are, we're not completely competent with ourselves. Yet,

0:16:50.800 --> 0:16:52.520
<v Speaker 1>even if we're not great at it, we can at

0:16:52.560 --> 0:16:55.640
<v Speaker 1>least do it. And as they say in the in

0:16:55.680 --> 0:16:58.520
<v Speaker 1>the Space Program, doing a bad job is better than

0:16:58.560 --> 0:17:01.840
<v Speaker 1>not doing it at all. They don't say that, do they.

0:17:02.720 --> 0:17:05.000
<v Speaker 1>I'm not sure that that might have been included on

0:17:05.040 --> 0:17:09.520
<v Speaker 1>the voyager plates and not not positive all right, So

0:17:09.840 --> 0:17:14.560
<v Speaker 1>before we consider the present solutions, before we consider genetically

0:17:14.560 --> 0:17:17.800
<v Speaker 1>modifying humans for space, I think it's a it's a

0:17:17.800 --> 0:17:21.960
<v Speaker 1>good opportunity to look back and see what two individuals,

0:17:22.280 --> 0:17:26.680
<v Speaker 1>Nathan Klein and Manfred Klein's said in their their Cyborg

0:17:26.760 --> 0:17:30.280
<v Speaker 1>paper back in nineteen sixty. Sure, because hey, if you

0:17:30.320 --> 0:17:33.760
<v Speaker 1>want to modify human beings to explore space, you don't

0:17:33.800 --> 0:17:36.240
<v Speaker 1>have to go straight to their genes. You could instead

0:17:37.040 --> 0:17:40.480
<v Speaker 1>basically give them a few mods right now. Yeah, And

0:17:40.600 --> 0:17:43.760
<v Speaker 1>that's that's basically what what these authors were arguing back

0:17:43.800 --> 0:17:46.639
<v Speaker 1>in nineteen sixty. They presented a grocery list of ways

0:17:46.720 --> 0:17:51.119
<v Speaker 1>that technology and medical science could retrofit the human body

0:17:51.840 --> 0:17:54.960
<v Speaker 1>for the star hopping lifestyle. And this is where the

0:17:54.960 --> 0:17:58.200
<v Speaker 1>concept of the cyborg came from, was this paper in

0:17:58.280 --> 0:18:01.480
<v Speaker 1>nineteen sixty by the client, by the clients, by client

0:18:01.560 --> 0:18:03.760
<v Speaker 1>and clients. Yes, one with a C, one with a K,

0:18:04.440 --> 0:18:06.600
<v Speaker 1>one one with an ass on the end, one without it.

0:18:06.720 --> 0:18:10.400
<v Speaker 1>So it always trips me up as well. But yeah,

0:18:10.400 --> 0:18:12.520
<v Speaker 1>they made this argument early on to say, hey, you

0:18:12.560 --> 0:18:13.840
<v Speaker 1>want to put people in space, you need to be

0:18:13.880 --> 0:18:17.440
<v Speaker 1>willing to change people. And we were not willing to

0:18:17.520 --> 0:18:20.080
<v Speaker 1>change people. Or we can look at it two different ways.

0:18:20.119 --> 0:18:21.760
<v Speaker 1>Either we were not willing to do it, or we

0:18:21.800 --> 0:18:25.679
<v Speaker 1>did not really have the the the scientific advances to

0:18:25.840 --> 0:18:28.840
<v Speaker 1>make those changes, at least not the more radical changes

0:18:28.840 --> 0:18:31.760
<v Speaker 1>that are proposed in this paper. This is a very

0:18:31.920 --> 0:18:34.000
<v Speaker 1>if you if you go read this paper, the tone

0:18:34.000 --> 0:18:36.800
<v Speaker 1>of it is incredibly gung ho, you know what I mean.

0:18:37.480 --> 0:18:39.719
<v Speaker 1>It's just so like, well, let's get her done, come on,

0:18:40.080 --> 0:18:43.600
<v Speaker 1>changing humans for space. Yeah, yeah, it is very gung ho. Uh.

0:18:43.960 --> 0:18:45.679
<v Speaker 1>I'm gonna read a quick quote from it here to

0:18:45.680 --> 0:18:49.720
<v Speaker 1>give you a taste. Solving the many technical problems involved

0:18:49.720 --> 0:18:53.080
<v Speaker 1>in man's space flight by adapting man to his environment

0:18:53.240 --> 0:18:56.679
<v Speaker 1>rather than vice versa will not only make a significant

0:18:56.720 --> 0:18:59.840
<v Speaker 1>step forward in man's scientific progress, but may well for

0:19:00.080 --> 0:19:03.359
<v Speaker 1>vide a new and larger dimension for man's spirit as well.

0:19:05.080 --> 0:19:07.639
<v Speaker 1>So they're like, let's not just change ourselves for space,

0:19:07.720 --> 0:19:10.479
<v Speaker 1>let's change ourselves for the principle of it. Yeah, it's

0:19:10.520 --> 0:19:12.120
<v Speaker 1>kind of It kind of gets back to the idea

0:19:12.160 --> 0:19:14.040
<v Speaker 1>that if you change the body, you change the soul.

0:19:14.080 --> 0:19:16.560
<v Speaker 1>When they're saying, hey, we're gonna in big in the body,

0:19:16.800 --> 0:19:19.600
<v Speaker 1>We're gonna in big in that human soul. Uh, you're

0:19:19.600 --> 0:19:25.840
<v Speaker 1>gonna it's a perfectly cromulent idea. So their recommendations were

0:19:25.840 --> 0:19:30.080
<v Speaker 1>all very much in the vein of retrofits. So we're

0:19:30.080 --> 0:19:32.040
<v Speaker 1>gonna get more into the idea of of sort of

0:19:33.040 --> 0:19:36.400
<v Speaker 1>you know, front end changes via genetic modification. But they

0:19:36.400 --> 0:19:38.520
<v Speaker 1>were all about taking the creature that is evolved for

0:19:38.640 --> 0:19:40.920
<v Speaker 1>this world and adapting it to survive in the other

0:19:41.320 --> 0:19:44.440
<v Speaker 1>or you know, in the space between worlds. Uh. That

0:19:44.640 --> 0:19:47.439
<v Speaker 1>they made a point of not altering the heredity of

0:19:47.480 --> 0:19:51.439
<v Speaker 1>the human being. Interesting, So here's another quote. In the past,

0:19:51.640 --> 0:19:54.760
<v Speaker 1>evolution brought about the altering of bodily functions to suit

0:19:54.840 --> 0:19:58.960
<v Speaker 1>different environments. Starting as of now, it will be possible

0:19:59.000 --> 0:20:02.920
<v Speaker 1>to achieve this to some degree without alteration of heredity

0:20:02.920 --> 0:20:09.240
<v Speaker 1>by suitable biochemical, physiological, and electronic modification modifications of man's

0:20:09.240 --> 0:20:13.960
<v Speaker 1>existing modus vivindi. Okay, so the way of getting along

0:20:14.000 --> 0:20:17.760
<v Speaker 1>in life previously we would make an adaptation to our

0:20:17.840 --> 0:20:20.840
<v Speaker 1>genes in a way that could be transferred from adult

0:20:20.880 --> 0:20:24.440
<v Speaker 1>to child. So it's a it's an indirect modification. It's

0:20:24.440 --> 0:20:27.560
<v Speaker 1>not the Slamarckian idea of like, well, I had to

0:20:27.800 --> 0:20:30.719
<v Speaker 1>reach up to a tree, so my arms got longer

0:20:30.760 --> 0:20:33.440
<v Speaker 1>and my kids had longer arms. It's no, you're born

0:20:33.560 --> 0:20:36.560
<v Speaker 1>with longer arms by accident you can reach the tree

0:20:36.600 --> 0:20:39.919
<v Speaker 1>better unless your kids get that as well. That's, you know,

0:20:40.080 --> 0:20:44.520
<v Speaker 1>the the accepted version of heredity. Now, of course, epigenetics

0:20:44.560 --> 0:20:47.680
<v Speaker 1>and lots of weird things have sort of modified that

0:20:47.800 --> 0:20:51.000
<v Speaker 1>slightly over the years, but still we basically are operating

0:20:51.480 --> 0:20:55.040
<v Speaker 1>on a germline heredity model for for where our body

0:20:55.080 --> 0:20:57.840
<v Speaker 1>traits come from. And they're saying, no, we don't have

0:20:57.920 --> 0:21:00.200
<v Speaker 1>to do that anymore. We can change people who were

0:21:00.240 --> 0:21:02.800
<v Speaker 1>alive right now. They don't have to get these changes

0:21:02.880 --> 0:21:08.280
<v Speaker 1>from their their ancestors, and the changes are rather fascinating.

0:21:08.320 --> 0:21:10.720
<v Speaker 1>The ones that they proposed. So they make suggestions in

0:21:10.720 --> 0:21:15.040
<v Speaker 1>including the use of hypothermic hibernation for extended space travel,

0:21:16.600 --> 0:21:21.480
<v Speaker 1>lowering body temperature, and administering various drugs through an automatic

0:21:21.480 --> 0:21:27.760
<v Speaker 1>osmotic pump of course to alter enzyme levels, low gravity tolerance, etcetera.

0:21:27.800 --> 0:21:30.000
<v Speaker 1>There's also the the idea that you could use a

0:21:30.160 --> 0:21:33.919
<v Speaker 1>solar or nuclear powered inverse fuel cell in place of

0:21:33.920 --> 0:21:37.439
<v Speaker 1>a lung. Isn't that just beautiful? A nuclear powered fuel

0:21:37.520 --> 0:21:42.080
<v Speaker 1>cell for respiration. And then this is probably my favorite

0:21:42.080 --> 0:21:47.639
<v Speaker 1>passage from the paper, fluid intake and output fluid balance

0:21:47.680 --> 0:21:51.280
<v Speaker 1>in the astronaut could be largely maintained via a shunt

0:21:51.640 --> 0:21:57.320
<v Speaker 1>from the uritors to the venous circulation after removal or

0:21:57.480 --> 0:22:05.160
<v Speaker 1>conversion of noxious substances. Sterilization of the gastro intestinal tract

0:22:05.400 --> 0:22:10.280
<v Speaker 1>plus intravenous or direct intra gastric feeding could reduce fecal

0:22:10.320 --> 0:22:15.320
<v Speaker 1>elimination to a minimum. And even this might be reutilized.

0:22:15.359 --> 0:22:19.120
<v Speaker 1>This is ambition, This ambition if I've ever seen it, Yeah,

0:22:19.119 --> 0:22:23.560
<v Speaker 1>this is the basic cybernetic replumbing of the human body. Yeah,

0:22:23.560 --> 0:22:26.720
<v Speaker 1>they're looking at what the human body does. They're saying, like, look,

0:22:26.920 --> 0:22:30.440
<v Speaker 1>pooping and peaking so much waste here. We gotta find

0:22:30.440 --> 0:22:33.680
<v Speaker 1>a way to reclaim all of this waste from poop

0:22:33.720 --> 0:22:38.080
<v Speaker 1>and p This enthusiasm reminds me of passage in Mary

0:22:38.160 --> 0:22:42.040
<v Speaker 1>Roach's excellent book Packing from Mars, But she talks about

0:22:42.040 --> 0:22:47.840
<v Speaker 1>the clash of culture between the NASA scientists and the

0:22:47.880 --> 0:22:52.439
<v Speaker 1>astronauts themselves, especially early on when the astronauts themselves tended

0:22:52.480 --> 0:22:56.680
<v Speaker 1>to be essentially cowboys. They were they were the they

0:22:56.680 --> 0:22:59.400
<v Speaker 1>were the test pilots. They were that they were very

0:22:59.720 --> 0:23:02.880
<v Speaker 1>man only men of the of of the sixties. Well,

0:23:02.920 --> 0:23:06.720
<v Speaker 1>I think actually the astronauts may have better embodied this, uh,

0:23:06.840 --> 0:23:09.960
<v Speaker 1>this client inclined, gung ho attitude of like, yeah, let's

0:23:09.960 --> 0:23:12.719
<v Speaker 1>do whatever, get her done. Well to a point, because,

0:23:13.240 --> 0:23:15.760
<v Speaker 1>as Roach points out, you have scientists who would say,

0:23:15.760 --> 0:23:19.439
<v Speaker 1>all right, uh to and to enable this kind of

0:23:19.440 --> 0:23:21.920
<v Speaker 1>space journey, that needs to be a certain amount of

0:23:22.040 --> 0:23:25.600
<v Speaker 1>like repurposing fecal matter, We need to we need to

0:23:25.640 --> 0:23:28.359
<v Speaker 1>figure out how to make the interior of the spaceship

0:23:28.440 --> 0:23:32.680
<v Speaker 1>out of consumable products, that sort of thing. And and

0:23:32.760 --> 0:23:34.560
<v Speaker 1>she said that there there would there would come a

0:23:34.600 --> 0:23:37.840
<v Speaker 1>point where the at the astronauts that they caught wind

0:23:37.880 --> 0:23:39.639
<v Speaker 1>of this idea, they would say Yeah, well we're not

0:23:39.680 --> 0:23:44.080
<v Speaker 1>doing that. That's just that's too far. So how's that,

0:23:44.160 --> 0:23:48.920
<v Speaker 1>how's that spaceship ready Salisbury stake meal coming? Well, it's

0:23:48.920 --> 0:23:52.160
<v Speaker 1>it's still a work in progress. But well, I guess

0:23:52.160 --> 0:23:55.800
<v Speaker 1>it does come down to the oh, just the the

0:23:55.840 --> 0:23:58.639
<v Speaker 1>scope of what you're trying to do. Just this just

0:23:58.920 --> 0:24:04.200
<v Speaker 1>this impossible dream of of of of taking terrestrial organisms

0:24:04.200 --> 0:24:08.320
<v Speaker 1>and allowing them to to journey and even thrive beyond

0:24:08.400 --> 0:24:10.920
<v Speaker 1>our world. You've got to You've got to enter into

0:24:10.960 --> 0:24:15.920
<v Speaker 1>that with a very gung home change everything attitude. Otherwise

0:24:16.000 --> 0:24:17.720
<v Speaker 1>how are you going to get there? Well? Yeah, there

0:24:17.760 --> 0:24:19.760
<v Speaker 1>there are different ways you could approach this. So if

0:24:19.800 --> 0:24:23.840
<v Speaker 1>you're talking about modifying astronauts for space travel, one way

0:24:23.880 --> 0:24:25.720
<v Speaker 1>you could think about it is how do we get

0:24:25.760 --> 0:24:29.440
<v Speaker 1>them through the mission? Right? How do we modify astronauts

0:24:29.480 --> 0:24:33.840
<v Speaker 1>so that they can complete their mission objectives and survive

0:24:33.960 --> 0:24:38.639
<v Speaker 1>the whole time and come back, versus thinking about modifying

0:24:38.640 --> 0:24:43.359
<v Speaker 1>astronauts to be the kind of organism where this is

0:24:43.440 --> 0:24:46.199
<v Speaker 1>the environment they thrive in. We're going to space is

0:24:46.320 --> 0:24:48.840
<v Speaker 1>natural to them, and it's not just to get them

0:24:48.880 --> 0:24:52.359
<v Speaker 1>through it without them dying or suffering debilitating illness, but

0:24:52.480 --> 0:24:55.359
<v Speaker 1>to make them at home in these new environments like

0:24:55.400 --> 0:24:58.879
<v Speaker 1>space and other planets. Does that make sense? So in

0:24:58.960 --> 0:25:02.080
<v Speaker 1>order to carry all this up, why should we depend

0:25:02.119 --> 0:25:05.800
<v Speaker 1>on crude aftermarket fixes like replumbing the human body and

0:25:06.040 --> 0:25:09.960
<v Speaker 1>installing nuclear lungs? Why do that when we could achieve

0:25:10.200 --> 0:25:14.960
<v Speaker 1>the ideal or you know, quote unquote ideal space faring

0:25:15.080 --> 0:25:20.239
<v Speaker 1>human via modern and near future gene editing technology. And

0:25:20.400 --> 0:25:22.959
<v Speaker 1>that is not as far fetched as it might sound.

0:25:23.440 --> 0:25:25.639
<v Speaker 1>And when we come back from this break, are you

0:25:25.680 --> 0:25:27.359
<v Speaker 1>ready for a break, Robert, I'm ready for a break.

0:25:27.359 --> 0:25:29.040
<v Speaker 1>All right, we'll take a quick break, and when we

0:25:29.119 --> 0:25:32.760
<v Speaker 1>come back, we're going to talk about the Crisper gene

0:25:32.840 --> 0:25:41.560
<v Speaker 1>editing method. Alright, we're back, so again, gene editing Crisper.

0:25:41.640 --> 0:25:44.600
<v Speaker 1>This is a topic that we've wanted to discuss for

0:25:44.640 --> 0:25:46.959
<v Speaker 1>some time. I know we've had listeners who've reached out

0:25:47.000 --> 0:25:48.840
<v Speaker 1>and said, he said, hey, do an episode on Crisper.

0:25:49.440 --> 0:25:52.240
<v Speaker 1>And I don't know about you, but and I know

0:25:52.280 --> 0:25:55.080
<v Speaker 1>you've you've covered Crisper, I think on other shows before,

0:25:55.160 --> 0:25:59.840
<v Speaker 1>but I always found it a bit huh intimidating because

0:26:00.040 --> 0:26:02.560
<v Speaker 1>there's there's too to look at Crisper and then draw

0:26:02.720 --> 0:26:07.479
<v Speaker 1>in sort of the the more everyday examples of how

0:26:07.520 --> 0:26:10.320
<v Speaker 1>it might be utilized in the fighting of diseases and whatnot,

0:26:10.440 --> 0:26:13.960
<v Speaker 1>and then drawing in a lot of the continued controversy

0:26:14.040 --> 0:26:18.320
<v Speaker 1>over GMO in general. It it becomes a bit intimidating,

0:26:18.359 --> 0:26:20.119
<v Speaker 1>and I like I like the idea of discussing it

0:26:20.200 --> 0:26:25.040
<v Speaker 1>here because it lines up nicely with a specific science

0:26:25.080 --> 0:26:31.000
<v Speaker 1>fiction flavored UM use for its products. Sure, for the

0:26:31.000 --> 0:26:33.760
<v Speaker 1>purposes of today's conversation, you can think of it as

0:26:33.920 --> 0:26:39.800
<v Speaker 1>the tiny micro molecular structure that makes better astronauts. Okay,

0:26:39.840 --> 0:26:42.560
<v Speaker 1>So CRISPER has been in the news for several years now,

0:26:42.680 --> 0:26:44.879
<v Speaker 1>and if you're one of those people who've heard about

0:26:44.880 --> 0:26:46.720
<v Speaker 1>it but you've been afraid to ask what it is,

0:26:46.800 --> 0:26:49.479
<v Speaker 1>you're not alone. We we get this question popping up

0:26:49.480 --> 0:26:51.919
<v Speaker 1>all the time. A lot of people, I think I've

0:26:51.960 --> 0:26:54.600
<v Speaker 1>heard of it, and they know it's a genetic technique.

0:26:54.760 --> 0:26:57.600
<v Speaker 1>They know genetesists are going crazy about its potential, both

0:26:57.640 --> 0:27:00.720
<v Speaker 1>for good and for ill, but they're not quite clear

0:27:00.840 --> 0:27:03.480
<v Speaker 1>what exactly is it. So I'm going to try to

0:27:03.560 --> 0:27:07.159
<v Speaker 1>give the easy version to explain what it is UM

0:27:07.200 --> 0:27:12.400
<v Speaker 1>without getting overly complicated. So CRISPER is the most common

0:27:12.440 --> 0:27:18.160
<v Speaker 1>shorthand for this new form of genetic technology that's revolutionizing

0:27:18.200 --> 0:27:22.199
<v Speaker 1>our ability to edit the genomes of living organisms. The

0:27:22.240 --> 0:27:25.360
<v Speaker 1>ability to edit a genome has already existed, so it's

0:27:25.359 --> 0:27:28.680
<v Speaker 1>not that we can edit genomes whereas we could not before.

0:27:29.160 --> 0:27:32.399
<v Speaker 1>That's existed at least since the nineteen nineties. But the

0:27:32.520 --> 0:27:37.000
<v Speaker 1>CRISPER tool kit is making the process easier, more efficient,

0:27:37.240 --> 0:27:41.280
<v Speaker 1>more precise, and cheaper. Now, when I say that it's

0:27:41.280 --> 0:27:43.800
<v Speaker 1>a tool or a technology, this can be a little

0:27:43.800 --> 0:27:47.280
<v Speaker 1>bit misleading because CRISPER is not something that was invented

0:27:47.320 --> 0:27:51.800
<v Speaker 1>in a lab. Rather, it was identified in living microbes

0:27:51.840 --> 0:27:56.280
<v Speaker 1>and then harnessed and modified for human scientific use. So

0:27:56.480 --> 0:28:00.800
<v Speaker 1>CRISPER is part of the natural immune system. It's the

0:28:00.840 --> 0:28:07.119
<v Speaker 1>immune function of single, single celled organisms like bacteria and archaea,

0:28:07.240 --> 0:28:11.960
<v Speaker 1>and it allows them to protect themselves against viruses. But

0:28:12.119 --> 0:28:14.119
<v Speaker 1>you still might be asking, wait a minute, but what

0:28:14.440 --> 0:28:17.640
<v Speaker 1>is it? What's the thing? So I'll try to explain

0:28:17.680 --> 0:28:21.320
<v Speaker 1>that as clearly as I can. CRISPER stands for clustered

0:28:21.520 --> 0:28:27.800
<v Speaker 1>regularly inner spaced short palindromic repeats, and in a direct sense,

0:28:27.880 --> 0:28:31.000
<v Speaker 1>these are just segments of DNA. So you've got the

0:28:31.080 --> 0:28:35.359
<v Speaker 1>genome of a prokariotic organism, for example, of bacterium of E. Coli,

0:28:35.800 --> 0:28:39.200
<v Speaker 1>and it's got its DNA, and along that DNA of

0:28:39.280 --> 0:28:41.960
<v Speaker 1>this E. Coal I, you'll find places where there are

0:28:41.960 --> 0:28:46.280
<v Speaker 1>these clusters of DNA that read the same forwards as

0:28:46.360 --> 0:28:50.960
<v Speaker 1>they read backwards their palindromic, just like palindromes in words. Robert,

0:28:51.200 --> 0:28:54.040
<v Speaker 1>do you have a favorite palindrome? I've got the I

0:28:54.120 --> 0:28:56.960
<v Speaker 1>love Rats Live on No Evil Star. Oh, man, that

0:28:57.160 --> 0:28:58.760
<v Speaker 1>that one is great. I don't think I've ever heard

0:28:58.800 --> 0:29:01.840
<v Speaker 1>that one before. But that's impossible to follow. I think

0:29:01.840 --> 0:29:03.680
<v Speaker 1>I saw that on the internet at some point. I

0:29:03.720 --> 0:29:06.080
<v Speaker 1>assume someone has a book with that title. That would

0:29:06.440 --> 0:29:09.680
<v Speaker 1>that's a great book title, Rats Live on No Evil Star.

0:29:10.320 --> 0:29:12.840
<v Speaker 1>It implies like rats may live on a good star.

0:29:14.320 --> 0:29:16.520
<v Speaker 1>It it feels like it should have there should be

0:29:16.560 --> 0:29:20.440
<v Speaker 1>some wisdom in their right plasma rats like where someone's like, man,

0:29:20.520 --> 0:29:22.520
<v Speaker 1>I just I haven't really down about the state of

0:29:22.520 --> 0:29:25.160
<v Speaker 1>the world today. Well you know what what they say,

0:29:25.880 --> 0:29:29.160
<v Speaker 1>Rats live on no Evil Star? Right on? Yeah, it

0:29:29.200 --> 0:29:32.800
<v Speaker 1>has that fortune cookie vibe. But anyway, so there are

0:29:32.840 --> 0:29:35.080
<v Speaker 1>these segments of DNA that read the same forwards as

0:29:35.120 --> 0:29:38.480
<v Speaker 1>backwards and in between them. So that's where the term

0:29:38.560 --> 0:29:42.040
<v Speaker 1>inner space comes in the eye and crisper. In between

0:29:42.080 --> 0:29:46.640
<v Speaker 1>these palindromic repeats are segments of DNA that exactly match

0:29:46.800 --> 0:29:51.880
<v Speaker 1>the DNA of viruses that are bacteria killing viruses like

0:29:52.040 --> 0:29:55.720
<v Speaker 1>bacteria phages. So in a similar way to how your

0:29:55.760 --> 0:30:00.480
<v Speaker 1>body makes antibodies, so your immune system can harget and

0:30:00.520 --> 0:30:03.760
<v Speaker 1>destroy germs that have already infected you in the past,

0:30:04.200 --> 0:30:09.040
<v Speaker 1>a bacterium makes copies of viral DNA and its genome,

0:30:09.200 --> 0:30:12.240
<v Speaker 1>so it can recognize that viral DNA in the future

0:30:12.320 --> 0:30:16.440
<v Speaker 1>and destroy it. But how does this happen? Well I

0:30:16.480 --> 0:30:19.600
<v Speaker 1>mentioned that crisper is shorthand. It's sort of a shorthand

0:30:19.600 --> 0:30:23.200
<v Speaker 1>for a tool kit of genes and proteins associated with

0:30:23.240 --> 0:30:26.120
<v Speaker 1>crisper in the wild, and one of these systems is

0:30:26.160 --> 0:30:29.080
<v Speaker 1>the Crisper CAST nine system. This is one of the

0:30:29.120 --> 0:30:31.600
<v Speaker 1>main ones that's actually being talked about when people talk

0:30:31.640 --> 0:30:37.719
<v Speaker 1>about crisper. So CAST genes are genes, they're Crisper associated genes,

0:30:37.720 --> 0:30:40.880
<v Speaker 1>which is where CAST comes from. And like all genes,

0:30:40.880 --> 0:30:43.520
<v Speaker 1>they're also made of DNA and they're part of the genome.

0:30:44.400 --> 0:30:48.960
<v Speaker 1>So DNA of course creates proteins, and proteins can do

0:30:49.120 --> 0:30:55.240
<v Speaker 1>work inside a cell. So CAST DNA makes DNA editing proteins.

0:30:55.400 --> 0:30:59.120
<v Speaker 1>If you think about your DNA has this part that

0:30:59.240 --> 0:31:04.280
<v Speaker 1>generate proteins that can make edits to your DNA. For example,

0:31:04.320 --> 0:31:07.640
<v Speaker 1>these would be enzymes called nucleases that are able to

0:31:07.720 --> 0:31:12.360
<v Speaker 1>snip DNA at certain points like scissors. So let's try

0:31:12.400 --> 0:31:15.760
<v Speaker 1>to imagine you are a prokaryotic cell. So you are

0:31:15.800 --> 0:31:20.680
<v Speaker 1>a cell of the bacterium Streptococcus pyogenes. Robert, can you

0:31:20.720 --> 0:31:24.920
<v Speaker 1>put yourself in that frame of mind? How hard is it? Well?

0:31:26.040 --> 0:31:28.520
<v Speaker 1>So it's it's it's more of a challenge than imagining

0:31:28.520 --> 0:31:31.160
<v Speaker 1>myself as a hoppit or a dwarf. But yeah, I

0:31:31.200 --> 0:31:34.040
<v Speaker 1>think I can do it. Okay, So you're this Streptococcus

0:31:34.040 --> 0:31:38.880
<v Speaker 1>bacterium and your CAST genes in your genome create this

0:31:38.920 --> 0:31:42.840
<v Speaker 1>big blob of proteins called CAST nine for Crisper associated

0:31:42.920 --> 0:31:47.760
<v Speaker 1>protein nine. And this CAST nine is is this protein

0:31:48.000 --> 0:31:51.720
<v Speaker 1>structure that's equipped with nucleases. Remember those are the enzymes

0:31:51.720 --> 0:31:55.400
<v Speaker 1>that can snip DNA, and it's also equipped with strands

0:31:55.480 --> 0:31:59.360
<v Speaker 1>of RNA matching all of the viral DNA that you've

0:31:59.400 --> 0:32:02.760
<v Speaker 1>stored up in your genome over the generations. So this

0:32:02.920 --> 0:32:06.920
<v Speaker 1>CAST nine object floats around inside you, inside this cell,

0:32:07.400 --> 0:32:10.240
<v Speaker 1>and if a virus comes along and squirt some of

0:32:10.280 --> 0:32:13.800
<v Speaker 1>its DNA into you, the CAST nine system can latch

0:32:13.880 --> 0:32:17.480
<v Speaker 1>onto that viral DNA with its matching set of crisper

0:32:17.640 --> 0:32:21.960
<v Speaker 1>RNA and then bust up that viral DNA with its nucleases. Right,

0:32:22.000 --> 0:32:24.440
<v Speaker 1>So it's got the profile of the viral DNA it

0:32:24.480 --> 0:32:28.280
<v Speaker 1>wants to catch, and it's got these proteins, these nucleases

0:32:28.720 --> 0:32:33.160
<v Speaker 1>that can destroy that viral DNA. Now, if it comes

0:32:33.160 --> 0:32:36.720
<v Speaker 1>across viral DNA that's not already stored in your genome,

0:32:37.160 --> 0:32:40.080
<v Speaker 1>it can also make a copy of that viral DNA,

0:32:40.400 --> 0:32:43.080
<v Speaker 1>snip a hole in the crisper part of your genome,

0:32:43.160 --> 0:32:46.000
<v Speaker 1>and insert it so that you were protected in the future.

0:32:46.080 --> 0:32:50.240
<v Speaker 1>So this gets incorporated into future generations of your germline.

0:32:50.960 --> 0:32:55.240
<v Speaker 1>Now that's some amazing molecular technology. But the way it

0:32:55.320 --> 0:32:58.560
<v Speaker 1>comes in to the scientific research is what if we

0:32:58.600 --> 0:33:02.520
<v Speaker 1>could harness that for our own purposes, And that's what

0:33:02.680 --> 0:33:05.680
<v Speaker 1>scientists within the past few years have been doing. So

0:33:05.920 --> 0:33:09.959
<v Speaker 1>the Crisper CAST nine technology is a modified version of

0:33:10.000 --> 0:33:13.320
<v Speaker 1>this biological system, and what it does is it allows

0:33:13.360 --> 0:33:18.160
<v Speaker 1>scientists to insert whatever DNA they want as the model

0:33:18.200 --> 0:33:21.240
<v Speaker 1>for the Crisper RNA in the cast nine system. So

0:33:21.560 --> 0:33:25.080
<v Speaker 1>this Crisper cast nine tool can be given a target

0:33:25.200 --> 0:33:28.080
<v Speaker 1>segment of DNA and then it can go in with

0:33:28.200 --> 0:33:32.080
<v Speaker 1>precision and snip that and only that section out of

0:33:32.120 --> 0:33:35.320
<v Speaker 1>your genome. You. Now, this can be useful if you

0:33:35.360 --> 0:33:38.440
<v Speaker 1>want to, for example, knockout a gene that's causing some

0:33:38.600 --> 0:33:42.160
<v Speaker 1>unwanted effect. Or it can even be used to insert

0:33:42.240 --> 0:33:45.920
<v Speaker 1>a specific string of DNA code at a targeted location,

0:33:45.960 --> 0:33:48.600
<v Speaker 1>and that's really interesting. So it can punch a hole

0:33:48.640 --> 0:33:51.360
<v Speaker 1>in a gene that you want knocked out, or it

0:33:51.400 --> 0:33:54.280
<v Speaker 1>can go in and make an edit. It can cut

0:33:54.320 --> 0:33:57.680
<v Speaker 1>open a hole, insert what you want, and move back out.

0:33:58.040 --> 0:34:00.120
<v Speaker 1>And what this all amounts to is that we can

0:34:00.280 --> 0:34:03.480
<v Speaker 1>edit our DNA and the DNA of other organisms with

0:34:03.600 --> 0:34:08.600
<v Speaker 1>much greater precision, much easier than ever before. And obviously

0:34:08.680 --> 0:34:10.640
<v Speaker 1>this is a big deal. This technology is going to

0:34:10.719 --> 0:34:14.160
<v Speaker 1>be incredibly powerful. It's not just a future thing. It's

0:34:14.200 --> 0:34:17.560
<v Speaker 1>already being used in the lab today as a research tool.

0:34:18.480 --> 0:34:22.920
<v Speaker 1>But there is this really strong, robust argument among scientists

0:34:22.920 --> 0:34:26.320
<v Speaker 1>and bioethicists about how it should be used. Right, But

0:34:26.480 --> 0:34:28.680
<v Speaker 1>most people are okay with the idea of trying to

0:34:28.719 --> 0:34:32.400
<v Speaker 1>develop uses that would, for example, heal a cancer causing

0:34:32.480 --> 0:34:36.360
<v Speaker 1>mutation in an adult human, or cure some other disease.

0:34:36.920 --> 0:34:39.600
<v Speaker 1>But other things are a lot more controversial when you

0:34:39.640 --> 0:34:43.239
<v Speaker 1>consider ideas like editing the germline DNA, and that's the

0:34:43.320 --> 0:34:46.600
<v Speaker 1>DNA that's not just part of your somatic cells, not

0:34:46.680 --> 0:34:49.400
<v Speaker 1>just part of your body now, but the DNA that

0:34:49.440 --> 0:34:53.040
<v Speaker 1>would get passed on from one generation to another. Because

0:34:53.080 --> 0:34:57.000
<v Speaker 1>if you make edits to that, you're essentially editing all

0:34:57.040 --> 0:35:00.560
<v Speaker 1>of the children and grandchildren and future to sentence that

0:35:00.600 --> 0:35:04.759
<v Speaker 1>a person would have without the consent of those future descendants.

0:35:05.080 --> 0:35:08.359
<v Speaker 1>You are modifying the human being. And in doing that

0:35:08.719 --> 0:35:12.280
<v Speaker 1>you were I mean that that encompasses all the potential

0:35:12.280 --> 0:35:15.640
<v Speaker 1>positives and negatives of that that godlike act. Yeah, and

0:35:15.640 --> 0:35:17.680
<v Speaker 1>and there are tons of other things to consider it.

0:35:17.760 --> 0:35:21.400
<v Speaker 1>I think it's a very interesting debate about what should

0:35:21.400 --> 0:35:24.040
<v Speaker 1>be done with this technology, if anything at all. I mean,

0:35:24.080 --> 0:35:26.640
<v Speaker 1>I think it's hard to argue that we shouldn't use

0:35:26.680 --> 0:35:29.640
<v Speaker 1>it for anything, because it's clearly a powerful research tool,

0:35:29.719 --> 0:35:33.239
<v Speaker 1>not just for editing people as they exist, but just

0:35:33.320 --> 0:35:36.680
<v Speaker 1>for for for example, identifying certain types of genes that

0:35:36.719 --> 0:35:39.480
<v Speaker 1>do certain things. It's powerful in the lab to find

0:35:39.520 --> 0:35:43.000
<v Speaker 1>things out about the human genome um, but there are

0:35:43.040 --> 0:35:45.319
<v Speaker 1>tons of questions about what it should be used for.

0:35:45.320 --> 0:35:48.359
<v Speaker 1>For example, we found this one really interesting article just

0:35:48.520 --> 0:35:50.719
<v Speaker 1>from I think, published just a few days ago in

0:35:50.800 --> 0:35:54.879
<v Speaker 1>June in the New York Times by Moises of Alaska's

0:35:54.960 --> 0:35:57.759
<v Speaker 1>man Off called and it was an argument quote in

0:35:57.880 --> 0:36:01.560
<v Speaker 1>favor of bad genes. Yeah, this is a great read.

0:36:01.640 --> 0:36:04.480
<v Speaker 1>He so he points in the article, he points to UH,

0:36:04.480 --> 0:36:08.320
<v Speaker 1>specifically to the case of sickle cell. So the gene

0:36:08.320 --> 0:36:11.960
<v Speaker 1>itself is usually found in people of Sub Saharan Africa,

0:36:12.320 --> 0:36:15.319
<v Speaker 1>the Middle East, in India, and having one copy of

0:36:15.320 --> 0:36:20.799
<v Speaker 1>the gene can prevent the worst symptoms of malaria and UH.

0:36:20.880 --> 0:36:23.880
<v Speaker 1>Whereas if you have if you have to, then you

0:36:23.920 --> 0:36:26.759
<v Speaker 1>get into the that that's where the problems arise. Right.

0:36:26.840 --> 0:36:29.839
<v Speaker 1>So yeah, so it's a it's a gene that if

0:36:29.920 --> 0:36:32.920
<v Speaker 1>you have two copies of this can cause a terrible

0:36:33.000 --> 0:36:35.600
<v Speaker 1>disease that leads to a lot of suffering. But if

0:36:35.640 --> 0:36:37.560
<v Speaker 1>you just have one copy of it, it can be

0:36:37.640 --> 0:36:41.120
<v Speaker 1>incredibly beneficial in the environment. So it's not it's not

0:36:41.160 --> 0:36:43.799
<v Speaker 1>just like a defect. It arose for a reason, it

0:36:43.880 --> 0:36:47.879
<v Speaker 1>provides a survival advantage. Right, it's just when it when

0:36:47.880 --> 0:36:49.440
<v Speaker 1>you end up having more than one, or when it

0:36:49.600 --> 0:36:51.279
<v Speaker 1>becomes out of balance. It's kind of it's kind of

0:36:51.320 --> 0:36:54.200
<v Speaker 1>the reality of life in general. Right. There are plenty

0:36:54.239 --> 0:36:56.680
<v Speaker 1>things in our life, in our life that in moderation

0:36:56.680 --> 0:36:59.680
<v Speaker 1>are very helpful, but it's when they become unbalanced. You know,

0:37:00.120 --> 0:37:03.440
<v Speaker 1>having having one pet dog in your house is cool.

0:37:03.800 --> 0:37:08.600
<v Speaker 1>Having twenty eighth is is an unbalanced reality. Yeah. Uh.

0:37:08.600 --> 0:37:11.080
<v Speaker 1>And and there are lots of cases of genes like this,

0:37:11.280 --> 0:37:14.480
<v Speaker 1>Genes that may appear that that do in fact cause

0:37:14.600 --> 0:37:18.520
<v Speaker 1>negative effects, but also do confer some strong advantage in

0:37:18.560 --> 0:37:22.200
<v Speaker 1>certain environments. Yeah. For instance, a gene variants that cause

0:37:22.719 --> 0:37:27.160
<v Speaker 1>lung disease cystic fibrosis. It's hypothesized that having just one

0:37:27.200 --> 0:37:32.040
<v Speaker 1>copy of the gene protects against TB tuberculosis, also known

0:37:32.080 --> 0:37:34.719
<v Speaker 1>as the White Plague of Europe of Esca's men Off

0:37:34.760 --> 0:37:38.560
<v Speaker 1>points out, uh in one and people from Northwest Europe

0:37:38.640 --> 0:37:41.879
<v Speaker 1>or Northwest European descent have it. So you're probably wondering

0:37:41.880 --> 0:37:43.160
<v Speaker 1>at this point, why do we need to worry about

0:37:43.239 --> 0:37:47.440
<v Speaker 1>established diseases? Why do we need to worry about ailments

0:37:47.440 --> 0:37:50.279
<v Speaker 1>for which we already have uh uh, you know, more

0:37:50.360 --> 0:37:53.799
<v Speaker 1>robust means of combating them. Well, the problem is that

0:37:53.920 --> 0:37:57.719
<v Speaker 1>new pathogens for which we don't have cures continue to emerge,

0:37:58.200 --> 0:38:01.919
<v Speaker 1>and some of these bad gene might be needed one day.

0:38:02.000 --> 0:38:04.400
<v Speaker 1>So I was thinking about this in terms of Batman.

0:38:04.600 --> 0:38:06.720
<v Speaker 1>It's like, if you have a situation where a Gotham city,

0:38:06.960 --> 0:38:10.200
<v Speaker 1>you've managed to to rid yourself of all of these criminals,

0:38:10.440 --> 0:38:13.480
<v Speaker 1>they're no more super villains running amuck. Let's kill Batman.

0:38:13.560 --> 0:38:15.360
<v Speaker 1>Let's get rid of Batman. Why don't we have a Batman.

0:38:15.400 --> 0:38:17.719
<v Speaker 1>He's just a distraction, right, He's probably a drain on

0:38:17.719 --> 0:38:21.560
<v Speaker 1>the local economy. It's a lot of traffic pile ups. Yeah, yeah,

0:38:21.640 --> 0:38:23.880
<v Speaker 1>and is and and is himself you know, an illegal

0:38:24.040 --> 0:38:27.160
<v Speaker 1>entity by the way. But then the Joker shows up

0:38:27.239 --> 0:38:29.480
<v Speaker 1>after you've gotten rid of Batman, yeah, or some new

0:38:29.520 --> 0:38:32.200
<v Speaker 1>super villain that we can't even envision yet, And then

0:38:32.280 --> 0:38:35.560
<v Speaker 1>are we going to have the basic vigilante tools to

0:38:35.600 --> 0:38:38.560
<v Speaker 1>combat him and in the case of of our own genome,

0:38:38.600 --> 0:38:42.239
<v Speaker 1>or we're gonna have the basic genomic tools in our

0:38:42.280 --> 0:38:45.360
<v Speaker 1>body for our body to combat this threat. And I

0:38:45.360 --> 0:38:48.640
<v Speaker 1>think this is a very interesting argument that I mean,

0:38:48.719 --> 0:38:51.600
<v Speaker 1>part of it is that we just don't understand everything

0:38:51.680 --> 0:38:56.400
<v Speaker 1>about our genome, and genes that do appear to cause

0:38:56.480 --> 0:38:59.920
<v Speaker 1>some kind of negative effect may also be doing something

0:39:00.080 --> 0:39:03.359
<v Speaker 1>important for us that we don't realize. That's right, And

0:39:03.800 --> 0:39:08.320
<v Speaker 1>as Vasco's men Off points out, environment is also a

0:39:08.400 --> 0:39:11.279
<v Speaker 1>key to here. So some of the gene variants now

0:39:11.320 --> 0:39:15.319
<v Speaker 1>linked with disease probably don't cause as many problems in

0:39:15.400 --> 0:39:20.799
<v Speaker 1>other environments, depending perhaps on microbes in their home environment. Uh,

0:39:20.880 --> 0:39:23.719
<v Speaker 1>he'd be pointsed, for instance, uh, the biome of a

0:39:23.840 --> 0:39:28.640
<v Speaker 1>less hygienic past. Uh, because you have to think about

0:39:28.680 --> 0:39:32.279
<v Speaker 1>the fact that, uh, you know, it's it's basically the

0:39:32.280 --> 0:39:36.040
<v Speaker 1>same scenario we have with space travel. The humans evolved

0:39:36.080 --> 0:39:39.200
<v Speaker 1>within a very firm set of parameters, and even within

0:39:39.320 --> 0:39:43.759
<v Speaker 1>our world they are there, they evolved in certain portions

0:39:43.880 --> 0:39:49.160
<v Speaker 1>of of our environment, geologically isolated for long periods of time,

0:39:49.719 --> 0:39:53.160
<v Speaker 1>and so you have to factor that into their into

0:39:53.160 --> 0:39:56.280
<v Speaker 1>their genes, into the expression of those genes, and into

0:39:56.440 --> 0:40:03.080
<v Speaker 1>the microbiome that become is uh pretty much standard for them. Yeah,

0:40:03.080 --> 0:40:05.799
<v Speaker 1>But I mean the broader application to space travel is

0:40:05.880 --> 0:40:09.359
<v Speaker 1>just that you don't know exactly what some of your

0:40:09.440 --> 0:40:13.680
<v Speaker 1>genes that appear to be uh, useless or harmful in

0:40:13.719 --> 0:40:17.479
<v Speaker 1>space might do for you once you're up there, right, Yeah,

0:40:17.480 --> 0:40:19.759
<v Speaker 1>there's there's actually a wonderful quote from this New York

0:40:19.760 --> 0:40:22.319
<v Speaker 1>Times article that I think sums up a lot of

0:40:22.320 --> 0:40:25.120
<v Speaker 1>what we're talking about here. He says, quote, we evolved

0:40:25.120 --> 0:40:28.279
<v Speaker 1>in environments that are radically different from today's, and some

0:40:28.400 --> 0:40:31.319
<v Speaker 1>of our genes may work better in those environments. This

0:40:31.440 --> 0:40:34.760
<v Speaker 1>complicates the idea of trying to perfect the human genome

0:40:34.800 --> 0:40:38.520
<v Speaker 1>with technology. Given how much the world has changed in

0:40:38.680 --> 0:40:41.080
<v Speaker 1>just the past one hundred and fifty years and how

0:40:41.160 --> 0:40:43.319
<v Speaker 1>much it's likely to change again in the next one

0:40:43.360 --> 0:40:47.200
<v Speaker 1>hundred and fifty the question is what environment will we

0:40:47.280 --> 0:40:50.920
<v Speaker 1>optimize our genes for? Yeah, now, what if here's another thing.

0:40:51.160 --> 0:40:54.319
<v Speaker 1>So imagine you've got people on an interstellar arc ship,

0:40:54.520 --> 0:40:58.600
<v Speaker 1>you know, it's an intergenerational or multigenerational starship taking you

0:40:58.640 --> 0:41:02.400
<v Speaker 1>to another planet, and you optimize their genes for survival

0:41:02.640 --> 0:41:06.719
<v Speaker 1>on that spaceship on the journey so that they can

0:41:06.760 --> 0:41:11.000
<v Speaker 1>survive and thrive in this spaceship environment. What if the

0:41:11.040 --> 0:41:14.880
<v Speaker 1>way you've optimized them for the spaceship undercuts their ability

0:41:14.920 --> 0:41:19.120
<v Speaker 1>to survive once they arrive at the target colonization planet. Yeah,

0:41:19.200 --> 0:41:21.279
<v Speaker 1>and then you run into a situation where you're having

0:41:21.320 --> 0:41:26.080
<v Speaker 1>to first adapt the crew members, and then there's a

0:41:26.080 --> 0:41:29.640
<v Speaker 1>different adaptation process that has to kick in for the

0:41:29.640 --> 0:41:33.680
<v Speaker 1>intended colonists. Anyway, I mean, I think this is not

0:41:33.880 --> 0:41:37.040
<v Speaker 1>necessarily an argument that we should never use crisper to

0:41:37.520 --> 0:41:40.200
<v Speaker 1>modify the human genome. But I think it is a

0:41:40.200 --> 0:41:43.440
<v Speaker 1>good word of caution to say, like, if there are

0:41:43.480 --> 0:41:47.359
<v Speaker 1>areas where we're not sure we understand everything a gene does,

0:41:47.520 --> 0:41:50.240
<v Speaker 1>and we're not we don't have a very clear picture

0:41:50.920 --> 0:41:53.400
<v Speaker 1>of the full range of effects of a certain gene

0:41:53.440 --> 0:41:55.640
<v Speaker 1>and what our life would be like without it, we

0:41:55.640 --> 0:42:00.600
<v Speaker 1>should be careful about being being too cavalier to change things. Yeah,

0:42:00.600 --> 0:42:04.040
<v Speaker 1>I mean, just we don't understand all of the ramifications

0:42:04.160 --> 0:42:06.799
<v Speaker 1>necessarily for some of these changes, But that that's kind

0:42:06.800 --> 0:42:10.319
<v Speaker 1>of baked into the challenge though, right is determining what

0:42:10.360 --> 0:42:14.800
<v Speaker 1>tweaks we can make that are going to potentially benefit

0:42:15.160 --> 0:42:20.600
<v Speaker 1>a human space traveler without creating any you know, additional constraints,

0:42:20.880 --> 0:42:24.680
<v Speaker 1>creating additional problems or or situation that could be problematic

0:42:24.760 --> 0:42:28.400
<v Speaker 1>later on. Yeah, And of course, all of the cautionary

0:42:28.480 --> 0:42:32.479
<v Speaker 1>questions and ethical dilemmas about Crisper don't in there. There's

0:42:32.480 --> 0:42:35.960
<v Speaker 1>a ton of stuff to consider, and um, that's probably

0:42:36.040 --> 0:42:39.120
<v Speaker 1>a realm for future episodes where we can talk more

0:42:39.120 --> 0:42:41.680
<v Speaker 1>about all of the controversies with Crisper. I know, just

0:42:41.760 --> 0:42:43.640
<v Speaker 1>in the past few months, I think there have been

0:42:43.680 --> 0:42:46.120
<v Speaker 1>there's been some back and forth with letters about the

0:42:46.200 --> 0:42:50.759
<v Speaker 1>ethics and and the wisdom of using Crisper in the

0:42:50.800 --> 0:42:53.239
<v Speaker 1>journal Nature. Yeah, and then on top of that, of

0:42:53.280 --> 0:42:57.040
<v Speaker 1>course they're just uh, you know, the public's response to it.

0:42:57.400 --> 0:42:59.560
<v Speaker 1>So as as King Wu pointed out in this panel,

0:42:59.560 --> 0:43:02.040
<v Speaker 1>there they are many ethnic groups in particular that have

0:43:02.480 --> 0:43:07.359
<v Speaker 1>not been well served by genetics and especially by eugenics

0:43:07.440 --> 0:43:10.560
<v Speaker 1>and the task which was it's worth the pointing out

0:43:10.560 --> 0:43:13.400
<v Speaker 1>both immoral science and bad science. So a failure on

0:43:13.440 --> 0:43:17.320
<v Speaker 1>two fronts. Um, So you know, to some to some degree,

0:43:17.320 --> 0:43:20.000
<v Speaker 1>it's it's unfair to to loop them together. But there's

0:43:20.120 --> 0:43:24.879
<v Speaker 1>undeniably a connection between eugenics and and genetics. Yeah, I mean,

0:43:24.920 --> 0:43:29.239
<v Speaker 1>you can see people's understandable fear about the idea of

0:43:29.280 --> 0:43:33.239
<v Speaker 1>making better humans. Like, Okay, so if somebody out there

0:43:33.320 --> 0:43:36.160
<v Speaker 1>is trying to engineer humans to be better humans, do

0:43:36.239 --> 0:43:39.600
<v Speaker 1>they have a specific idea about what better humans are

0:43:39.680 --> 0:43:43.640
<v Speaker 1>and is that not just like uh, having fewer diseases,

0:43:43.680 --> 0:43:46.600
<v Speaker 1>but do they also have aesthetic ideas? Yeah, and these

0:43:46.640 --> 0:43:49.640
<v Speaker 1>are all questions we need to ask as we potentially

0:43:49.680 --> 0:43:52.960
<v Speaker 1>enter into an age where where this kind of technology

0:43:53.040 --> 0:43:55.879
<v Speaker 1>is utilized or more you know, we consider its use.

0:43:56.960 --> 0:43:59.919
<v Speaker 1>But while a lot of groups take issue with gene atit,

0:44:00.440 --> 0:44:03.600
<v Speaker 1>Woo points out that the most people, when when questioned

0:44:03.600 --> 0:44:06.080
<v Speaker 1>about it, they're cooler with the idea of the technology

0:44:06.120 --> 0:44:09.719
<v Speaker 1>being used to better protect astronauts in space. Yeah. So

0:44:09.800 --> 0:44:13.760
<v Speaker 1>I think people are generally cooler with the more specific applications.

0:44:14.160 --> 0:44:17.920
<v Speaker 1>Feeling cancer patients, Okay, Yeah, I'm good with that. Modifying

0:44:17.960 --> 0:44:21.200
<v Speaker 1>astronauts for space sounds great. Yeah, tear them up, do

0:44:21.560 --> 0:44:24.040
<v Speaker 1>what you gotta do. But when it just comes to

0:44:24.120 --> 0:44:28.560
<v Speaker 1>this general, free form, open ended should we change human beings,

0:44:28.760 --> 0:44:31.879
<v Speaker 1>that starts to get a little squeaky. Yeah, I mean,

0:44:31.880 --> 0:44:33.839
<v Speaker 1>I mean, I guess it's it's kind of always the case,

0:44:33.960 --> 0:44:35.960
<v Speaker 1>right Like if you if you if you make the

0:44:36.040 --> 0:44:39.759
<v Speaker 1>question broad enough, if you, for instance, were to say,

0:44:39.880 --> 0:44:44.160
<v Speaker 1>should humans live in the sky, No, that sounds preposterous.

0:44:44.239 --> 0:44:48.680
<v Speaker 1>Humans should not live in the sky. Humans were were

0:44:48.719 --> 0:44:51.680
<v Speaker 1>you know, evolved or were created? If you want to

0:44:51.680 --> 0:44:54.320
<v Speaker 1>go that route to to live here on the ground.

0:44:54.400 --> 0:44:56.480
<v Speaker 1>We should absolutely not live in the sky. If we

0:44:56.480 --> 0:44:58.200
<v Speaker 1>went in the sky, we'd fall down and die. But

0:44:58.239 --> 0:45:00.600
<v Speaker 1>if you were to say, oh, well, should we create

0:45:01.480 --> 0:45:03.920
<v Speaker 1>planes that we can we can fly around in some

0:45:03.960 --> 0:45:05.719
<v Speaker 1>sort of vehicle that allow us to go from point

0:45:05.719 --> 0:45:09.000
<v Speaker 1>A to point B. Could we create a luxury hotel

0:45:09.120 --> 0:45:11.920
<v Speaker 1>on an airship and then if you if you're interested

0:45:11.920 --> 0:45:14.680
<v Speaker 1>in it, and you have enough of money to flip

0:45:14.719 --> 0:45:16.239
<v Speaker 1>the bill, you can go out there and spend the

0:45:16.360 --> 0:45:19.000
<v Speaker 1>night in the air. Yes, that sounds much more reasonable.

0:45:19.360 --> 0:45:21.640
<v Speaker 1>It's also kind of like if you ask people, would

0:45:21.680 --> 0:45:26.279
<v Speaker 1>you be okay with scientists experimenting on ways to resuscitate

0:45:26.280 --> 0:45:29.640
<v Speaker 1>people who have encountered twenty minutes of brain death, it

0:45:29.760 --> 0:45:32.160
<v Speaker 1>might be like, well, sure, but if you say, should

0:45:32.200 --> 0:45:36.640
<v Speaker 1>we be working on experiments to revive the dead? Yeah,

0:45:36.680 --> 0:45:39.719
<v Speaker 1>then you're gonna get some pushback. Alright, we're gonna take

0:45:39.719 --> 0:45:42.080
<v Speaker 1>another quick breaking. When we come back, we will continue

0:45:42.120 --> 0:45:51.680
<v Speaker 1>our discussion about the genetically modified astronaut. Alright, we're back,

0:45:51.840 --> 0:45:56.920
<v Speaker 1>so we should we should definitely drive home something that

0:45:57.000 --> 0:46:00.360
<v Speaker 1>we've we've discussed in length and past episodes, the icularly

0:46:00.400 --> 0:46:03.919
<v Speaker 1>Your Life as a Mars colonist, and that is that

0:46:04.680 --> 0:46:08.120
<v Speaker 1>the traveling in space or and certainly traveling to other

0:46:08.200 --> 0:46:11.120
<v Speaker 1>world it's gonna open you up to a number of

0:46:12.120 --> 0:46:14.960
<v Speaker 1>unhealthy scenarios. I guess youho'ld say, yeah, I got. We

0:46:15.040 --> 0:46:17.759
<v Speaker 1>also touched on this in five Reasons Never to Take

0:46:17.800 --> 0:46:20.759
<v Speaker 1>your Space Helmet Off. So the big one, the one,

0:46:20.760 --> 0:46:22.040
<v Speaker 1>that one that we spent a lot of time in

0:46:22.080 --> 0:46:26.520
<v Speaker 1>that episode with, is of course radiation. Exactly. Now, there

0:46:26.520 --> 0:46:32.279
<v Speaker 1>are in fact organisms that are naturally radio resistant organisms.

0:46:32.480 --> 0:46:34.799
<v Speaker 1>I would tend to think, just intuitively if I had

0:46:34.840 --> 0:46:37.680
<v Speaker 1>never read anything about this, the radiation is one of

0:46:37.680 --> 0:46:40.400
<v Speaker 1>those things kind of like a fire or something that

0:46:40.560 --> 0:46:44.120
<v Speaker 1>just kind of kills everything. But there are in fact

0:46:44.800 --> 0:46:49.760
<v Speaker 1>vastly different levels of susceptibility to radiation in the animal

0:46:49.840 --> 0:46:53.920
<v Speaker 1>kingdom and in organisms generally. And it's not just that

0:46:53.960 --> 0:46:57.960
<v Speaker 1>there are some extreme aphile micro organisms that can survive radiation.

0:46:58.000 --> 0:47:01.000
<v Speaker 1>I mean, we know about tartar grades and things like that,

0:47:01.160 --> 0:47:03.319
<v Speaker 1>but there you know, even if you just look at

0:47:03.360 --> 0:47:06.759
<v Speaker 1>animals like it looks like turtles have more radio resistance

0:47:06.800 --> 0:47:12.080
<v Speaker 1>than dogs probably, so there is some room within large

0:47:12.160 --> 0:47:15.399
<v Speaker 1>mammals like us to modify our bodies to be more

0:47:15.480 --> 0:47:19.680
<v Speaker 1>resistant to radiation. Alright, So, so one potential there is

0:47:19.719 --> 0:47:21.120
<v Speaker 1>if we can and again there are a lot of

0:47:21.239 --> 0:47:24.360
<v Speaker 1>gifts and and and and butts and and all of this,

0:47:24.480 --> 0:47:29.239
<v Speaker 1>But if we can figure out ways to alter the

0:47:29.280 --> 0:47:34.879
<v Speaker 1>human genome to encourage a greater resistance to radiation, greater

0:47:35.000 --> 0:47:39.719
<v Speaker 1>protection from radiation, that would be an area of opportunity. Yeah,

0:47:39.760 --> 0:47:41.520
<v Speaker 1>and I mean there are lots of ways you can

0:47:41.520 --> 0:47:43.239
<v Speaker 1>think that you might be able to do this. One

0:47:43.239 --> 0:47:48.759
<v Speaker 1>would be the body already has natural DNA repair properties, right.

0:47:48.800 --> 0:47:53.319
<v Speaker 1>If there's DNA damage, the genome will try to put

0:47:53.360 --> 0:47:56.200
<v Speaker 1>itself back together, and of course, if it puts itself

0:47:56.200 --> 0:47:58.880
<v Speaker 1>back together wrong, this can lead to a mutation that

0:47:58.960 --> 0:48:01.480
<v Speaker 1>can have bad effects and maybe cause cancer or something

0:48:01.520 --> 0:48:04.920
<v Speaker 1>like that. But you could try to genetically modify the

0:48:05.000 --> 0:48:09.320
<v Speaker 1>human body so as to have stronger DNA repair precision

0:48:09.440 --> 0:48:15.320
<v Speaker 1>and stronger DNA repair resilience. Or here's another possibility, Robert,

0:48:15.320 --> 0:48:18.440
<v Speaker 1>remember when we did the episode about the eater of rads,

0:48:18.520 --> 0:48:23.680
<v Speaker 1>the radiation resistant fungi that that supposedly, if these results

0:48:23.680 --> 0:48:27.200
<v Speaker 1>are correct, and not only survive in the presence of,

0:48:27.400 --> 0:48:31.239
<v Speaker 1>for example, gamma radiation, but can apparently gain some kind

0:48:31.239 --> 0:48:34.279
<v Speaker 1>of usable bio energy from it. And this was done

0:48:34.320 --> 0:48:38.560
<v Speaker 1>by absorbing the radiation through melaninrich cells. Now, I wonder

0:48:38.680 --> 0:48:41.600
<v Speaker 1>if you could try to do something similar to take

0:48:41.640 --> 0:48:45.920
<v Speaker 1>some inspiration from that and try to modify human somatic

0:48:46.000 --> 0:48:49.239
<v Speaker 1>cells so that they have similar properties of of you know,

0:48:49.360 --> 0:48:54.040
<v Speaker 1>internal chemicals and molecules that are absorbent of radiation and

0:48:54.120 --> 0:48:57.480
<v Speaker 1>dissipating the radiation instead of allowing it to penetrate the

0:48:57.560 --> 0:49:00.600
<v Speaker 1>DNA in your cells. Yes, so, so we're looking at

0:49:00.600 --> 0:49:03.960
<v Speaker 1>ways to further protect the body against radiation and make

0:49:03.960 --> 0:49:07.000
<v Speaker 1>it less susceptible to damage from radiation and UH and

0:49:07.000 --> 0:49:11.799
<v Speaker 1>then potentially better repair itself. Okay, Now on top of that,

0:49:11.880 --> 0:49:15.000
<v Speaker 1>one one UH issue that was brought up in this

0:49:15.200 --> 0:49:18.719
<v Speaker 1>World Science Festival discussion is a cancer treatment in the

0:49:18.719 --> 0:49:21.759
<v Speaker 1>reduction of cancer risk totally. Some of that falls in

0:49:21.840 --> 0:49:24.360
<v Speaker 1>line with the radiation here for sure. But you know,

0:49:24.400 --> 0:49:27.040
<v Speaker 1>at first this might seem like more of a terrestrial concern, right,

0:49:27.440 --> 0:49:29.800
<v Speaker 1>But what if you're talking about a ten year trip

0:49:30.239 --> 0:49:33.520
<v Speaker 1>and then you realize you've developed cancer three years in

0:49:33.880 --> 0:49:37.680
<v Speaker 1>five years in so you can't take a risk. You

0:49:37.680 --> 0:49:40.600
<v Speaker 1>can't risk an astro not coming down with cancer developing

0:49:40.640 --> 0:49:43.879
<v Speaker 1>cancer uh during the trip, because they might not have

0:49:44.120 --> 0:49:46.800
<v Speaker 1>time to make it back to Earth for treatment, or

0:49:46.840 --> 0:49:48.960
<v Speaker 1>it might not even be in the cards for a

0:49:48.960 --> 0:49:51.360
<v Speaker 1>return trip at all. Sure, I mean, if this is

0:49:51.400 --> 0:49:53.920
<v Speaker 1>a colonization, or if it's a trip to Mars, this

0:49:54.040 --> 0:49:56.040
<v Speaker 1>is going to be a multi year kind of thing. Yeah.

0:49:56.080 --> 0:49:58.440
<v Speaker 1>I mean, even if it's one of these, uh, these

0:49:58.480 --> 0:50:01.200
<v Speaker 1>one way trips that we've in a lot of discussion about.

0:50:02.239 --> 0:50:04.880
<v Speaker 1>The plan is probably not for you to get to

0:50:05.000 --> 0:50:07.320
<v Speaker 1>Mars and then die immediately. I mean, that may happen.

0:50:07.360 --> 0:50:10.680
<v Speaker 1>That's thus are the risks of such a venture, but

0:50:12.160 --> 0:50:14.120
<v Speaker 1>you it would be it would be even more of

0:50:14.120 --> 0:50:16.640
<v Speaker 1>a tragedy if it were to occur due to uh

0:50:16.880 --> 0:50:20.239
<v Speaker 1>to the effects of cancer, um, you know, within the

0:50:20.280 --> 0:50:24.600
<v Speaker 1>first year of landing on Mars totally. Now, what about

0:50:24.600 --> 0:50:27.080
<v Speaker 1>the effects of micro gravity? This is obviously going to

0:50:27.160 --> 0:50:30.560
<v Speaker 1>be one of the biggest challenges that biological systems encounter

0:50:30.640 --> 0:50:33.759
<v Speaker 1>in space. We are adapted to an environment with Earth

0:50:33.760 --> 0:50:36.680
<v Speaker 1>gravity with one G. You go to a place without

0:50:36.760 --> 0:50:40.359
<v Speaker 1>one G, or at least without consistent one G, you're

0:50:40.440 --> 0:50:44.520
<v Speaker 1>going to encounter some biological disturbances. Yeah, this is this

0:50:44.560 --> 0:50:47.120
<v Speaker 1>is the area where and I think we've covered some

0:50:47.200 --> 0:50:49.120
<v Speaker 1>of the science on this show before, Like this is

0:50:49.120 --> 0:50:51.239
<v Speaker 1>an area that there's been a lot of study, Uh,

0:50:51.440 --> 0:50:54.640
<v Speaker 1>not necessary, a lot of great answers other than lots

0:50:54.640 --> 0:50:58.600
<v Speaker 1>of exercise and uh and in certain vitamin supplements. Get

0:50:58.640 --> 0:51:02.600
<v Speaker 1>on that treadmill. Uh yeah, and and tread use of

0:51:02.640 --> 0:51:04.759
<v Speaker 1>to the treadmills. The use of exercise devices seems to

0:51:04.760 --> 0:51:06.200
<v Speaker 1>be one of the key ways to make up for

0:51:06.200 --> 0:51:09.120
<v Speaker 1>it because we don't have artificial gravity. Even though we

0:51:09.160 --> 0:51:13.160
<v Speaker 1>have these these wonderful sci fi visions of of an

0:51:13.280 --> 0:51:17.280
<v Speaker 1>artificial gravity created via centrifugal force via like a spinning

0:51:17.440 --> 0:51:21.399
<v Speaker 1>space station, like a tourist or like the space station

0:51:21.440 --> 0:51:23.960
<v Speaker 1>we see in two thousand one of Space Odyssey, we

0:51:24.360 --> 0:51:27.839
<v Speaker 1>these ideas are largely unproven. Um and it I mean,

0:51:27.880 --> 0:51:30.280
<v Speaker 1>we we do know you could create a force towards

0:51:30.320 --> 0:51:32.600
<v Speaker 1>the floor if you did that. Yes, yeah, we we

0:51:32.640 --> 0:51:35.200
<v Speaker 1>know we know that. Yeah, we know we could create

0:51:35.239 --> 0:51:38.439
<v Speaker 1>the force, but we don't know exactly what it would

0:51:38.520 --> 0:51:41.879
<v Speaker 1>be like to try and then function as an astronaut

0:51:42.400 --> 0:51:45.440
<v Speaker 1>in such an environment, but for a really long period

0:51:45.440 --> 0:51:47.759
<v Speaker 1>of time especially Yeah, and then think about if you

0:51:47.840 --> 0:51:50.080
<v Speaker 1>get to maybe so if you're going to another planet.

0:51:50.840 --> 0:51:52.600
<v Speaker 1>Once you get to the planet, you're not really going

0:51:52.680 --> 0:51:55.000
<v Speaker 1>to have that option there the planet, You're just gonna

0:51:55.000 --> 0:51:59.200
<v Speaker 1>be dealing with whatever the natural gravity of that planet is. Yeah,

0:51:59.440 --> 0:52:01.960
<v Speaker 1>it was brought up in the talk by A. Caleb

0:52:02.040 --> 0:52:04.759
<v Speaker 1>sharf h that we might have to if we were

0:52:04.800 --> 0:52:09.239
<v Speaker 1>on one of these spinning artificial environment uh constructions, we

0:52:09.320 --> 0:52:12.200
<v Speaker 1>might have to deal with the of course, the coreolis effects.

0:52:12.320 --> 0:52:14.440
<v Speaker 1>What would happen if I threw an apple to you

0:52:15.360 --> 0:52:18.560
<v Speaker 1>on board one of these space stations. I don't know.

0:52:18.640 --> 0:52:21.480
<v Speaker 1>I've never tried to throw an apple in a spinning drum.

0:52:21.560 --> 0:52:24.600
<v Speaker 1>What would happen? I don't know. But it's one of

0:52:24.600 --> 0:52:27.200
<v Speaker 1>those those new realities you would have to get used

0:52:27.239 --> 0:52:30.760
<v Speaker 1>to just the way objects behave in the space, because

0:52:31.120 --> 0:52:34.920
<v Speaker 1>you would be replicating gravity, but it would be it

0:52:34.960 --> 0:52:37.640
<v Speaker 1>would be artificial gravity in in a in a in

0:52:37.640 --> 0:52:40.160
<v Speaker 1>a very real sense. I mean, there are just so

0:52:40.200 --> 0:52:45.239
<v Speaker 1>many ways that space messes with you in a systemic way.

0:52:45.400 --> 0:52:47.760
<v Speaker 1>In some cases, I think it's not even totally clear

0:52:48.280 --> 0:52:52.040
<v Speaker 1>when say, astronauts on the International Space Station exhibit symptoms,

0:52:52.480 --> 0:52:55.920
<v Speaker 1>what in what ways the symptoms are informed by the

0:52:55.960 --> 0:52:58.680
<v Speaker 1>different conditions of space. So you've got micro gravity, But

0:52:58.760 --> 0:53:01.120
<v Speaker 1>it's not just the micrograp You've also got a different

0:53:01.160 --> 0:53:04.279
<v Speaker 1>microbial environment, and you've got you know, you've got a

0:53:04.320 --> 0:53:06.799
<v Speaker 1>million different things going on at once. Some of it's

0:53:06.800 --> 0:53:10.359
<v Speaker 1>probably just stress and things like that. So we don't

0:53:10.400 --> 0:53:13.440
<v Speaker 1>even know at this point for sure exactly what parts

0:53:13.440 --> 0:53:16.920
<v Speaker 1>of space travel do what to you. In some cases

0:53:16.920 --> 0:53:18.600
<v Speaker 1>we have a good idea, in other cases were not

0:53:18.680 --> 0:53:22.120
<v Speaker 1>as sure. Yeah, and the talk, Mason also pointed out

0:53:22.160 --> 0:53:24.799
<v Speaker 1>that when you when you get into space, thousands of

0:53:24.880 --> 0:53:28.480
<v Speaker 1>genes become perturbed. So we have a short list of

0:53:28.600 --> 0:53:31.040
<v Speaker 1>risk genes for space and an example of this would

0:53:31.080 --> 0:53:35.760
<v Speaker 1>be stress response genes, DNA damage and repair genes. Yeah,

0:53:35.880 --> 0:53:38.160
<v Speaker 1>and a lot of this was to be expected because

0:53:38.320 --> 0:53:41.320
<v Speaker 1>gene expression changes all the time. It happens, it happens

0:53:41.320 --> 0:53:44.319
<v Speaker 1>here on Earth every time you eat. It kind of

0:53:44.320 --> 0:53:47.399
<v Speaker 1>goes back to our discussion about the the role that

0:53:47.719 --> 0:53:51.560
<v Speaker 1>your local environment, your local microbiome, would have on the

0:53:51.560 --> 0:53:54.160
<v Speaker 1>expression of your genes to and that could that gets

0:53:54.160 --> 0:53:57.560
<v Speaker 1>into another fact of life in space pointed out by

0:53:57.600 --> 0:54:00.600
<v Speaker 1>Mason and this, and that's that that microbes become more

0:54:00.680 --> 0:54:04.560
<v Speaker 1>active in space. So salmonella, for instance, becomes more deadly

0:54:04.680 --> 0:54:08.239
<v Speaker 1>for mice that have been studied in orbital environments. Yeah.

0:54:08.280 --> 0:54:10.200
<v Speaker 1>I think we mentioned that in the Reasons Not to

0:54:10.200 --> 0:54:12.719
<v Speaker 1>Take Your Space Helmet Off episode. So, yeah, once you

0:54:12.760 --> 0:54:16.840
<v Speaker 1>get into space, it appears that space conditions, for whatever reason,

0:54:17.080 --> 0:54:22.239
<v Speaker 1>increase the virulence of pathogens, which is just great. Who

0:54:22.280 --> 0:54:26.640
<v Speaker 1>decided that would happen? Um. Yeah, it increases the virulence

0:54:26.640 --> 0:54:30.879
<v Speaker 1>of pathogens and depresses your immune function, right, it leads

0:54:30.920 --> 0:54:34.520
<v Speaker 1>to these immune problems. Like we we talked in in

0:54:34.560 --> 0:54:37.040
<v Speaker 1>that other episode about all the ways that space messes

0:54:37.040 --> 0:54:40.640
<v Speaker 1>with your immune system, including creating these sort of almost

0:54:40.680 --> 0:54:45.560
<v Speaker 1>allergic like effects. And so maybe that is one fruitful

0:54:45.600 --> 0:54:48.360
<v Speaker 1>place to start looking about modification of humans. If you

0:54:48.400 --> 0:54:51.160
<v Speaker 1>want to modify astronauts to survive in space, you might

0:54:51.200 --> 0:54:54.480
<v Speaker 1>need to make changes to how the immune system is

0:54:54.520 --> 0:54:57.319
<v Speaker 1>expressed and regulated by the genome. Yeah, I mean it

0:54:57.400 --> 0:55:00.719
<v Speaker 1>sounds like just across the board. You know, in the

0:55:00.760 --> 0:55:04.120
<v Speaker 1>same way that an astronaut is does not it is

0:55:04.120 --> 0:55:07.759
<v Speaker 1>probably not going to be your average physical specimen, you know.

0:55:07.840 --> 0:55:10.120
<v Speaker 1>They they need to be Yeah, they need to be

0:55:10.160 --> 0:55:11.759
<v Speaker 1>in shape, they need to they need to be able

0:55:11.800 --> 0:55:15.280
<v Speaker 1>to survive the rigors of space. So in order to

0:55:15.280 --> 0:55:17.920
<v Speaker 1>to tweak the genome you need to essentially tweak for

0:55:18.120 --> 0:55:22.120
<v Speaker 1>just a really healthy person. So ignore you know, don't

0:55:22.120 --> 0:55:25.240
<v Speaker 1>worry about crab clause just yet, Like, focus on creating

0:55:25.239 --> 0:55:28.200
<v Speaker 1>a really healthy astronaut that's going to be able to

0:55:28.239 --> 0:55:31.520
<v Speaker 1>withstand these changes that's gonna you know, for instance, not

0:55:32.280 --> 0:55:35.320
<v Speaker 1>suffer as much bone and muscle loss due to the

0:55:35.360 --> 0:55:38.760
<v Speaker 1>effects of micro gravity. You know. It's it's also worth

0:55:38.800 --> 0:55:42.239
<v Speaker 1>noting in all of this that that some of these

0:55:42.280 --> 0:55:44.920
<v Speaker 1>negatives that we're talking about, you know, or but are

0:55:44.960 --> 0:55:50.120
<v Speaker 1>actually examples of the body adapting in real time. Uh,

0:55:50.160 --> 0:55:53.839
<v Speaker 1>you know, not evolving, but adapting. Uh So, so all

0:55:53.880 --> 0:55:57.440
<v Speaker 1>that bone and muscle mass uh that is lost unless

0:55:57.440 --> 0:55:59.600
<v Speaker 1>you know, vigorous exercises kept up to sort of keep

0:55:59.600 --> 0:56:03.320
<v Speaker 1>it in check. But that's essentially the body acclimatizing to

0:56:03.600 --> 0:56:07.040
<v Speaker 1>this low gravity environment. It's being smart, it's using its

0:56:07.080 --> 0:56:10.480
<v Speaker 1>resources wisely. Yeah, thing, I don't need to be strong.

0:56:11.440 --> 0:56:13.279
<v Speaker 1>And then there are other changes that are happening as well,

0:56:13.320 --> 0:56:15.480
<v Speaker 1>Like it was pointed out that you will end up

0:56:15.480 --> 0:56:18.080
<v Speaker 1>with callouses on the tops of your feet as well,

0:56:18.880 --> 0:56:21.719
<v Speaker 1>because it's not just the bottom so your feet that

0:56:21.760 --> 0:56:25.080
<v Speaker 1>are coming in contact with the surfaces in your environment.

0:56:25.280 --> 0:56:29.719
<v Speaker 1>You're becoming You're not this just top down gravity organism anymore.

0:56:29.520 --> 0:56:33.040
<v Speaker 1>You're weird. Ye. And then there's the example of clothing.

0:56:33.560 --> 0:56:37.239
<v Speaker 1>So Mason uh Or he talked a bit about in

0:56:37.280 --> 0:56:40.680
<v Speaker 1>this about his work with the NASA astronaut twins Mark

0:56:40.719 --> 0:56:43.640
<v Speaker 1>and Scott Kelly, because he did a number of of

0:56:43.640 --> 0:56:46.399
<v Speaker 1>of of experiments who was essentially you know, looking at

0:56:46.440 --> 0:56:49.960
<v Speaker 1>the at the genetic differences between the two after one

0:56:50.000 --> 0:56:53.160
<v Speaker 1>of them returned from space and uh And he pointed

0:56:53.160 --> 0:56:58.839
<v Speaker 1>out that that after Scott Kelly returned, like he could

0:56:58.880 --> 0:57:01.920
<v Speaker 1>not wear clothing for a couple of days because just

0:57:02.000 --> 0:57:06.400
<v Speaker 1>the feeling of clothing held down by gravity on his

0:57:06.480 --> 0:57:12.120
<v Speaker 1>skin made him experience quote unquote pain. Yeah. So it's

0:57:12.160 --> 0:57:15.200
<v Speaker 1>just that you become that unaccustomed to even just minor

0:57:15.760 --> 0:57:22.160
<v Speaker 1>aspects of of gravity. It's hard to imagine your shirt hurts. Yeah,

0:57:22.240 --> 0:57:24.120
<v Speaker 1>And and that's just and that's one of the small things.

0:57:24.120 --> 0:57:27.360
<v Speaker 1>It's not even getting into you know, you know, potential

0:57:27.560 --> 0:57:31.120
<v Speaker 1>you know, radiation or or or major bone and muscle

0:57:31.160 --> 0:57:35.080
<v Speaker 1>mass loss. Oh. And then of course there's there's the

0:57:35.080 --> 0:57:38.120
<v Speaker 1>fact that your circadian rhythm is screwed up and is

0:57:38.200 --> 0:57:41.280
<v Speaker 1>you're trying to sleep unless you have your hands trapped down,

0:57:41.280 --> 0:57:43.320
<v Speaker 1>they're gonna be floating in your face, you know, phantom

0:57:43.400 --> 0:57:46.720
<v Speaker 1>hands coming at you. And this is something I hadn't

0:57:46.720 --> 0:57:50.680
<v Speaker 1>thought about that Mason pointed out, is that you're you're

0:57:50.720 --> 0:57:53.680
<v Speaker 1>setting there, you're laying there, floating there. However you want

0:57:53.680 --> 0:57:56.600
<v Speaker 1>to look at it, strapped down, trying to sleep, and

0:57:56.640 --> 0:58:00.360
<v Speaker 1>you're already up, like puffed up and snotty, just from

0:58:01.400 --> 0:58:03.640
<v Speaker 1>just hey fever kind of condition, yeah, hey fever kind

0:58:03.680 --> 0:58:05.680
<v Speaker 1>of condition. Just but by virtue of being in space

0:58:05.720 --> 0:58:10.240
<v Speaker 1>and sharing everybody's micro biome. But you're also liable to

0:58:10.280 --> 0:58:13.160
<v Speaker 1>wind up sweeping in a bubble of c O two

0:58:13.760 --> 0:58:16.720
<v Speaker 1>what yeah, what he refers to as uh in your

0:58:16.720 --> 0:58:21.440
<v Speaker 1>own respiratory excrement um, just by virtue of breathing into

0:58:21.480 --> 0:58:25.960
<v Speaker 1>this this uh, this this microgravity environment. So like the

0:58:26.080 --> 0:58:29.240
<v Speaker 1>gases don't disperse is easily, I guess. Yeah, I've never

0:58:29.280 --> 0:58:32.280
<v Speaker 1>heard that before. I had not either, but it makes

0:58:32.280 --> 0:58:35.480
<v Speaker 1>sense now. In a rare reversal of everything we've been

0:58:35.480 --> 0:58:38.840
<v Speaker 1>talking about, of all these dire consequences of venturing into space,

0:58:39.280 --> 0:58:44.320
<v Speaker 1>Mason points out that our telomeres actually get longer in space. Oh,

0:58:44.440 --> 0:58:48.720
<v Speaker 1>the telomeres now are these um, these are things having

0:58:48.760 --> 0:58:53.000
<v Speaker 1>to do supposedly with the natural length of cell division

0:58:53.040 --> 0:58:56.120
<v Speaker 1>and reproduction in the human body. Yes, so yeah, you

0:58:56.120 --> 0:58:59.280
<v Speaker 1>get into the like the whole science of telomeres, and

0:59:01.080 --> 0:59:03.280
<v Speaker 1>we won't get into it here. There's a there's there's

0:59:03.280 --> 0:59:05.080
<v Speaker 1>an article on how stuff works dot com that I

0:59:05.120 --> 0:59:07.520
<v Speaker 1>wrote years ago about it. But the short version is

0:59:07.880 --> 0:59:13.120
<v Speaker 1>that the telomere length is directly related to uh to lifespan.

0:59:13.720 --> 0:59:18.760
<v Speaker 1>So if timomeres are longer than than than life is longer.

0:59:18.960 --> 0:59:22.480
<v Speaker 1>That's kind of the very brief explanation of it. So

0:59:22.600 --> 0:59:25.080
<v Speaker 1>you could make an argument that if you were in

0:59:25.480 --> 0:59:28.480
<v Speaker 1>that life and space lasts longer, that you could live

0:59:28.560 --> 0:59:31.560
<v Speaker 1>longer in space, of course, if you were ignoring many

0:59:31.560 --> 0:59:35.040
<v Speaker 1>of these other debilitating effects. So why did roy Baby

0:59:35.080 --> 0:59:37.439
<v Speaker 1>come back to Earth? If he wants more life, maybe

0:59:37.440 --> 0:59:40.080
<v Speaker 1>he should have stayed in space. Well, but I mean

0:59:40.120 --> 0:59:42.560
<v Speaker 1>that's kind of the thing, right, that the telomeres were

0:59:42.640 --> 0:59:46.880
<v Speaker 1>artificially shortened on replicance, I guess yeah, Or maybe it's

0:59:46.920 --> 0:59:50.280
<v Speaker 1>because he came back because this is I don't know

0:59:50.360 --> 0:59:53.400
<v Speaker 1>if if there's been much treatment on this, but the

0:59:54.120 --> 0:59:57.960
<v Speaker 1>replicants in Blade Runner, where they made for use and

0:59:58.040 --> 1:00:00.760
<v Speaker 1>off world scenarios for use in space. Yeah, I think so.

1:00:01.720 --> 1:00:04.320
<v Speaker 1>You know, it seems like you could probably create a

1:00:04.360 --> 1:00:09.320
<v Speaker 1>replicant then that would live longer in space, and if

1:00:09.360 --> 1:00:12.120
<v Speaker 1>a return to a higher gravity world, it would have

1:00:12.240 --> 1:00:15.880
<v Speaker 1>a genetic effect on it that would kill it. I mean,

1:00:16.120 --> 1:00:18.480
<v Speaker 1>this is almost a perfect example of one of the

1:00:18.600 --> 1:00:21.960
<v Speaker 1>dangers of you say you want to create crisper modified

1:00:22.000 --> 1:00:27.040
<v Speaker 1>astronauts thrive in space. What if their mission changed and

1:00:27.160 --> 1:00:29.960
<v Speaker 1>they wanted to come back to Earth. A thing optimized

1:00:30.000 --> 1:00:33.360
<v Speaker 1>for space would no longer be optimized for Earth. And

1:00:33.400 --> 1:00:36.640
<v Speaker 1>there are many cases where if you want a genetic

1:00:36.640 --> 1:00:39.919
<v Speaker 1>advantage in one environment, it's not just like a it's

1:00:40.440 --> 1:00:43.200
<v Speaker 1>it's not just like a win with no drawback. You know,

1:00:43.600 --> 1:00:45.760
<v Speaker 1>if you were to come back to Earth, it would

1:00:45.760 --> 1:00:48.520
<v Speaker 1>actually hurt you. There's a there's a win loss, there's

1:00:48.520 --> 1:00:51.080
<v Speaker 1>a trade off. Yeah. I guess part of it comes

1:00:51.120 --> 1:00:54.800
<v Speaker 1>down to, like, how how far into the future are

1:00:54.800 --> 1:00:58.520
<v Speaker 1>you gazing? You know, are you creating creating and maybe

1:00:58.560 --> 1:01:02.400
<v Speaker 1>a too heavier turn, but are you augmitting augmenting people

1:01:02.560 --> 1:01:06.600
<v Speaker 1>too to remain within this next phase? Are you essentially

1:01:06.600 --> 1:01:13.240
<v Speaker 1>creating an an interplanetary humanoid species or subspecies? Are you

1:01:13.280 --> 1:01:18.000
<v Speaker 1>are you creating subspecies then that are acclimatized to various

1:01:18.000 --> 1:01:21.240
<v Speaker 1>soft world environments or are you are you saying, all right,

1:01:21.240 --> 1:01:24.240
<v Speaker 1>these people are gonna come back to and then and

1:01:24.280 --> 1:01:27.680
<v Speaker 1>then like, how does that affect their rights as a citizen? Uh,

1:01:28.000 --> 1:01:30.400
<v Speaker 1>as a member of the human species. How much would

1:01:30.440 --> 1:01:33.400
<v Speaker 1>you have to modify astronauts before they began to lose

1:01:33.480 --> 1:01:36.920
<v Speaker 1>their sense of kinship with earth dwelling humans and earth

1:01:37.000 --> 1:01:40.000
<v Speaker 1>dwelling humans lost their sense of kinship for the astronauts.

1:01:40.240 --> 1:01:43.920
<v Speaker 1>I mean, we are incredibly genetically similar to chimpanzees and

1:01:44.040 --> 1:01:48.560
<v Speaker 1>sometimes show a remarkable callousness despite how similar we are.

1:01:48.960 --> 1:01:51.280
<v Speaker 1>How much would you have how many genes would you

1:01:51.280 --> 1:01:54.720
<v Speaker 1>have to change before we no longer recognize the astronaut

1:01:54.760 --> 1:01:57.240
<v Speaker 1>just the same animal as us. Well, and think of

1:01:57.320 --> 1:02:00.160
<v Speaker 1>just spatial distance here on Earth And granted this kind

1:02:00.160 --> 1:02:05.320
<v Speaker 1>of a clunky analogy, but uh, think of the callousness

1:02:05.360 --> 1:02:08.080
<v Speaker 1>that one group of people can show for another on

1:02:08.200 --> 1:02:11.760
<v Speaker 1>the other side of the Earth. And then imagine us

1:02:11.800 --> 1:02:17.000
<v Speaker 1>sending people even greater distances, like distances between people that

1:02:17.080 --> 1:02:22.760
<v Speaker 1>have not been possible until until the advent of interplanetary travel.

1:02:23.680 --> 1:02:26.920
<v Speaker 1>In other words, the spatial distance between people will be

1:02:26.960 --> 1:02:30.240
<v Speaker 1>greater than it has ever been in human history. Yeah,

1:02:30.360 --> 1:02:33.040
<v Speaker 1>what will be the ramifications of that? Yeah, that's a

1:02:33.040 --> 1:02:36.480
<v Speaker 1>tough thing to consider. Um, and then when you start

1:02:36.520 --> 1:02:40.120
<v Speaker 1>factoring in the the increased time it takes to transmit

1:02:40.160 --> 1:02:44.959
<v Speaker 1>information as interconnected as we are on on Earth, now,

1:02:45.640 --> 1:02:48.000
<v Speaker 1>like that is not necessarily going to carry over to

1:02:48.080 --> 1:02:52.720
<v Speaker 1>an interplanetary scenario. I'm thinking kind of you know, far

1:02:52.800 --> 1:02:56.240
<v Speaker 1>future here, But can you imagine, you know, how out

1:02:56.280 --> 1:02:58.960
<v Speaker 1>of the loop you feel when you come in fourteen

1:02:59.040 --> 1:03:02.200
<v Speaker 1>minutes after the beginning of a public discussion on Twitter

1:03:02.240 --> 1:03:05.480
<v Speaker 1>about from public event that just happened. Now, people on

1:03:05.520 --> 1:03:08.400
<v Speaker 1>Mars are going to be like that constantly, where Mars

1:03:08.400 --> 1:03:09.920
<v Speaker 1>will have to have its own Twitter. I guess it's

1:03:09.960 --> 1:03:13.240
<v Speaker 1>the thing of Martian Twitter and Earth Twitter. Uh, that's

1:03:13.240 --> 1:03:18.080
<v Speaker 1>the only way to do it from Mars Twitter. Now,

1:03:18.440 --> 1:03:19.800
<v Speaker 1>I think it would be great. It would just be

1:03:19.880 --> 1:03:23.360
<v Speaker 1>one person. Would you need a genetic modification in order

1:03:23.400 --> 1:03:25.160
<v Speaker 1>to be able to keep up with the jokes on

1:03:25.200 --> 1:03:33.320
<v Speaker 1>Mars Twitter? Yeah, I mean either red red humor gene maybe.

1:03:33.360 --> 1:03:35.720
<v Speaker 1>I mean you do get into so many different when

1:03:35.760 --> 1:03:39.160
<v Speaker 1>you when you start thinking you know, far future. Uh,

1:03:39.360 --> 1:03:42.280
<v Speaker 1>there's so many a cultural changes that can occur, so

1:03:42.320 --> 1:03:47.880
<v Speaker 1>many changes in value on top of various microbial changes

1:03:47.880 --> 1:03:50.560
<v Speaker 1>that have taken place. Now, a lot of the changes

1:03:50.560 --> 1:03:54.040
<v Speaker 1>we've talked about so far, the potential genetic changes have

1:03:54.160 --> 1:03:57.000
<v Speaker 1>been to survive in a space environment, you know, just

1:03:57.040 --> 1:03:59.960
<v Speaker 1>to get along with all of the natural hardships you'd face.

1:04:00.520 --> 1:04:03.600
<v Speaker 1>But there are also things that you could imagine changing

1:04:03.640 --> 1:04:06.960
<v Speaker 1>about people just to make them like more efficient in space.

1:04:07.480 --> 1:04:09.440
<v Speaker 1>I mean, one of the things I can imagine would

1:04:09.440 --> 1:04:13.120
<v Speaker 1>be like better eyesight for low light conditions. He wanted

1:04:13.160 --> 1:04:15.560
<v Speaker 1>to have that in space to conserve power or all

1:04:15.640 --> 1:04:19.360
<v Speaker 1>kinds of power conserving things like could you make people

1:04:19.480 --> 1:04:22.720
<v Speaker 1>that had slower metabolisms and space so they needed to

1:04:22.800 --> 1:04:27.280
<v Speaker 1>consume fewer resources. Would you make people who's I don't know,

1:04:27.360 --> 1:04:30.560
<v Speaker 1>genetic engineering so their kidneys are more efficient so they

1:04:30.560 --> 1:04:32.720
<v Speaker 1>don't don't need to drink as much water to stay

1:04:32.760 --> 1:04:36.200
<v Speaker 1>healthy or something. Yeah, And I wonder, I mean, I

1:04:36.240 --> 1:04:38.440
<v Speaker 1>can't help it draw in I guess kind of kind

1:04:38.440 --> 1:04:42.040
<v Speaker 1>of clunky comparisons to other natural world organisms and say, well,

1:04:42.080 --> 1:04:43.920
<v Speaker 1>if we had if we had this feature, would that

1:04:43.960 --> 1:04:46.480
<v Speaker 1>make us a little uh, you know, a little better

1:04:46.480 --> 1:04:48.840
<v Speaker 1>in a microgravity environment? For instance, I'm thinking like a

1:04:48.920 --> 1:04:52.440
<v Speaker 1>cat's whiskers, Like if humans had cat whiskers, would they

1:04:52.480 --> 1:04:55.440
<v Speaker 1>be better at floating around through various tubes and whatnot

1:04:55.480 --> 1:04:59.880
<v Speaker 1>because they have a very ready read on the space

1:05:00.040 --> 1:05:03.080
<v Speaker 1>or is the size of their body. Now, maybe humans

1:05:03.360 --> 1:05:07.280
<v Speaker 1>instead of crab claws need spider spinnerets in space so

1:05:07.320 --> 1:05:10.760
<v Speaker 1>that they can like shoot webs out and pull themselves

1:05:10.800 --> 1:05:14.600
<v Speaker 1>from place to place in a microgravity environment. Huh. I

1:05:14.640 --> 1:05:17.000
<v Speaker 1>wonder how would we spend I guess maybe we would

1:05:17.040 --> 1:05:19.880
<v Speaker 1>like milk it from our nipples. That would be because

1:05:20.080 --> 1:05:22.600
<v Speaker 1>because I don't know how, I like a spider man

1:05:23.200 --> 1:05:28.480
<v Speaker 1>web shooter uh scenario would work. But I'm thinking back

1:05:28.520 --> 1:05:31.880
<v Speaker 1>on the the goat we discussed that had been genetically

1:05:31.880 --> 1:05:35.680
<v Speaker 1>augmented to produce spider silk from its uh it's utters

1:05:35.680 --> 1:05:37.920
<v Speaker 1>the spider goat. Yeah, so if we could create our

1:05:37.960 --> 1:05:41.640
<v Speaker 1>own spider nipple scenario, I can imagine like a shirtless astronaut.

1:05:42.080 --> 1:05:44.480
<v Speaker 1>He's floating around in the cabin and he needs to

1:05:44.480 --> 1:05:46.920
<v Speaker 1>move across the room, so he reaches down to his nipple,

1:05:47.880 --> 1:05:50.760
<v Speaker 1>pulls out some some silk, and like throws a drag

1:05:50.800 --> 1:05:54.840
<v Speaker 1>line across the room and then navigates on that. I

1:05:54.880 --> 1:05:57.040
<v Speaker 1>commend you, Robert, but I think we've reached the end

1:05:57.040 --> 1:06:01.240
<v Speaker 1>of this conversation probably so uh, anytime the spider goat

1:06:01.320 --> 1:06:03.360
<v Speaker 1>is invoked, you've you've kind of reached the limits of

1:06:03.440 --> 1:06:06.920
<v Speaker 1>human understanding. I guess, well, hey, you out there, what

1:06:07.040 --> 1:06:09.080
<v Speaker 1>do you think would be one of the most useful

1:06:09.160 --> 1:06:13.640
<v Speaker 1>or interesting genetic modifications for future astronauts and space colonists?

1:06:13.800 --> 1:06:16.520
<v Speaker 1>Or do you think that we shouldn't dabble in trying

1:06:16.520 --> 1:06:20.640
<v Speaker 1>to modify trying to modify humans except for maybe life

1:06:20.640 --> 1:06:24.080
<v Speaker 1>threatening or survival needs. And to what extent should we

1:06:24.160 --> 1:06:27.960
<v Speaker 1>focus on changing individuals into what extent should we focus

1:06:27.960 --> 1:06:30.200
<v Speaker 1>on changing the species? Like, are you just changing an

1:06:30.240 --> 1:06:34.040
<v Speaker 1>individual astronaut or a group of astronauts for a journey

1:06:34.080 --> 1:06:37.760
<v Speaker 1>for a mission, or are you altering the human species

1:06:37.880 --> 1:06:41.280
<v Speaker 1>entirely and creating a subspecies that's going to thrive in

1:06:41.280 --> 1:06:43.400
<v Speaker 1>a particular environment. Yeah, I don't know. It's a really

1:06:43.400 --> 1:06:46.400
<v Speaker 1>interesting question. So, yeah, you out there, let us know

1:06:46.480 --> 1:06:49.520
<v Speaker 1>what you think. Yeah, hit us with those other science

1:06:49.560 --> 1:06:53.080
<v Speaker 1>fiction examples. I'm sure there are tons of them. As always,

1:06:53.080 --> 1:06:57.200
<v Speaker 1>you can find us all the normal places where on Facebook, Twitter, Instagram,

<v Speaker 1>Tumbler all those websites. We also have the mother show

1:07:00.040 --> 1:07:01.880
<v Speaker 1>up stuff to bow your Mind dot com. That's where

1:07:01.880 --> 1:07:05.080
<v Speaker 1>we'll find all the podcast episodes dating back to the

1:07:05.160 --> 1:07:08.800
<v Speaker 1>very beginning. You'll find videos, blog posts, et cetera, and
