1 00:00:03,840 --> 00:00:06,720 Speaker 1: Welcome to Stuff to Blow Your Mind from how Stuff 2 00:00:06,720 --> 00:00:13,640 Speaker 1: Works dot com. Hey, welcome to Stuff to Blow your Mind. 3 00:00:13,640 --> 00:00:16,360 Speaker 1: My name is Robert Lamb and my name is Julie Douglas. 4 00:00:16,680 --> 00:00:19,040 Speaker 1: And we just recorded an episode about some of the 5 00:00:19,079 --> 00:00:23,480 Speaker 1: big stories in science during the last year, during twelve uh, 6 00:00:23,520 --> 00:00:26,079 Speaker 1: and now we're doing a second episode where we're just 7 00:00:26,079 --> 00:00:29,400 Speaker 1: gonna run through some bits of really fascinating science that 8 00:00:29,400 --> 00:00:31,600 Speaker 1: you might have missed. Uh, A lot of its stuff 9 00:00:31,600 --> 00:00:35,560 Speaker 1: that we could have conceivably maybe have done an episode about. 10 00:00:36,120 --> 00:00:38,199 Speaker 1: Or maybe it's like something that's really interesting but just 11 00:00:38,320 --> 00:00:40,920 Speaker 1: not quite enough to do a whole episode on. So 12 00:00:41,159 --> 00:00:43,839 Speaker 1: consider this kind of a sampler platter of some of 13 00:00:43,840 --> 00:00:50,159 Speaker 1: the stranger chocolates from now I get to say, a 14 00:00:50,200 --> 00:00:55,800 Speaker 1: poo poo platter, Yes, poop ladder of odd science from Um, 15 00:00:55,840 --> 00:00:58,360 Speaker 1: we're gonna kick off with with my favorite from this 16 00:00:58,720 --> 00:01:02,680 Speaker 1: this bunch and this is a worse the Immortal jellyfish 17 00:01:02,720 --> 00:01:06,559 Speaker 1: the quote unquote Benjamin Button of the Animal Kingdom. Uh. 18 00:01:06,600 --> 00:01:08,720 Speaker 1: A lot of headlines had some fun with this, I 19 00:01:08,720 --> 00:01:11,039 Speaker 1: mean have to fund with Most of these are the headlines. 20 00:01:11,400 --> 00:01:14,480 Speaker 1: New York Times ran a story titled can a jellyfish Unlocked? 21 00:01:14,520 --> 00:01:17,720 Speaker 1: The Secrets of immortality. So you have a number of 22 00:01:18,440 --> 00:01:23,000 Speaker 1: I mean just pit there. Yeah, they dropped in immortality 23 00:01:23,040 --> 00:01:25,959 Speaker 1: in the headline, which that's gonna that generates some interest 24 00:01:26,000 --> 00:01:28,760 Speaker 1: because we all want to live live, not forever, at 25 00:01:28,800 --> 00:01:32,000 Speaker 1: least maybe a little more than we have a lotted 26 00:01:32,040 --> 00:01:36,680 Speaker 1: to us. So, uh, it's it's instantly fascinating. So the 27 00:01:36,880 --> 00:01:44,320 Speaker 1: jellyfish in question is the Tatopsis dorney, which to all 28 00:01:44,360 --> 00:01:48,480 Speaker 1: appearances looks like jellyfish. There's there's nothing particularly amazing about 29 00:01:48,480 --> 00:01:51,360 Speaker 1: but what what happens here is that, um nothing amazing 30 00:01:51,360 --> 00:01:54,280 Speaker 1: about it in just appearance, but in function it does 31 00:01:54,280 --> 00:01:57,160 Speaker 1: some amazing things. What appears to happen is that it 32 00:01:57,520 --> 00:02:00,720 Speaker 1: quote unquote reverses an in age unil it reaches an 33 00:02:00,720 --> 00:02:04,320 Speaker 1: early stage, earlier stage of its development. Now to really 34 00:02:04,360 --> 00:02:07,320 Speaker 1: understand what's going on here, you have to picture the 35 00:02:07,360 --> 00:02:10,760 Speaker 1: life cycle of the jellyfish and h So what happens, 36 00:02:10,840 --> 00:02:13,520 Speaker 1: all right, So you having an adult jellyfish, a medusa, 37 00:02:13,840 --> 00:02:17,880 Speaker 1: all right, when it reproduces, it drops off this planny 38 00:02:17,919 --> 00:02:21,480 Speaker 1: little larva. Alright, this larva floats down to the bottom 39 00:02:21,520 --> 00:02:24,440 Speaker 1: of of the sea there and there it grows into 40 00:02:24,520 --> 00:02:27,120 Speaker 1: a polyp and then the budding polyp emits this ifira, 41 00:02:27,360 --> 00:02:31,920 Speaker 1: this little sort of mini pseudo jellyfish that then floats 42 00:02:32,000 --> 00:02:35,120 Speaker 1: up and becomes the adult jellyfish of it. Right, right, 43 00:02:35,919 --> 00:02:39,959 Speaker 1: So that's the basic life cycle. Now, what happens normally 44 00:02:40,160 --> 00:02:42,440 Speaker 1: is that you have an adult jellyfish that reproduces a 45 00:02:42,440 --> 00:02:45,960 Speaker 1: few times, starts getting a little old, it starts to starve, 46 00:02:46,080 --> 00:02:47,639 Speaker 1: or the water gets a little too hot, and then 47 00:02:47,680 --> 00:02:50,480 Speaker 1: it dies. It shuffles off this mortal coil. You know. 48 00:02:50,520 --> 00:02:53,760 Speaker 1: This is basically like any life form right reaches the 49 00:02:53,760 --> 00:02:56,520 Speaker 1: adult stage. The adult stage is about reproducing. Now, it's 50 00:02:56,560 --> 00:03:00,520 Speaker 1: worth noting that, as with many other organisms, um, the 51 00:03:00,560 --> 00:03:03,720 Speaker 1: adult stage is not the only stage that can reproduce. Uh, 52 00:03:03,760 --> 00:03:07,160 Speaker 1: there's also some a sexual reproduction that takes place at 53 00:03:07,160 --> 00:03:11,160 Speaker 1: the poly up stage. But but generally, in most organisms 54 00:03:11,240 --> 00:03:14,040 Speaker 1: reach it reaches the adult stage, it reproduces, and then 55 00:03:14,400 --> 00:03:16,600 Speaker 1: it either dies immediately or maybe it carries on a 56 00:03:16,639 --> 00:03:19,920 Speaker 1: little longer, but generally its function is done. You've reached 57 00:03:19,960 --> 00:03:23,400 Speaker 1: the adulthood stage. You've reproduced. That's it. You have to 58 00:03:23,440 --> 00:03:26,359 Speaker 1: get off the stage and make room for the other players. 59 00:03:26,400 --> 00:03:30,800 Speaker 1: But not so with this particular jellyfish. Now it does 60 00:03:30,840 --> 00:03:35,200 Speaker 1: not quite Benjamin Button, Like, that would be a wrong analogy. 61 00:03:35,720 --> 00:03:37,520 Speaker 1: What would be a better analogy is that is not 62 00:03:37,560 --> 00:03:40,000 Speaker 1: that like an old man grows young again. But imagine 63 00:03:40,040 --> 00:03:43,040 Speaker 1: an old man walking down the street and just collapses 64 00:03:43,240 --> 00:03:46,920 Speaker 1: under the weight of his like old awfulness, and then 65 00:03:46,960 --> 00:03:50,000 Speaker 1: just melts into a pile of goo on the sidewalk, 66 00:03:50,320 --> 00:03:54,480 Speaker 1: and then out of that goo crawls a naked, slime 67 00:03:54,520 --> 00:03:58,160 Speaker 1: covered infant, which then grows up into an adult. I 68 00:03:58,240 --> 00:04:01,360 Speaker 1: like that. I like that. Pat Krug marine biologists says 69 00:04:01,520 --> 00:04:04,640 Speaker 1: that when they do reach the end of this cycle, uh, 70 00:04:04,680 --> 00:04:06,440 Speaker 1: they get really stressed out and they collapse to the 71 00:04:06,440 --> 00:04:11,520 Speaker 1: bottom and melt, But instead of dying, they really reorganize 72 00:04:12,080 --> 00:04:15,520 Speaker 1: its tissues and forms a new little polyp, so, as 73 00:04:15,560 --> 00:04:19,760 Speaker 1: you say, sort of climbing from the primordial goo and 74 00:04:19,880 --> 00:04:25,200 Speaker 1: reforming itself. Um. And it's interesting because Craig says that 75 00:04:25,279 --> 00:04:28,520 Speaker 1: it it's it's almost like it skips it's having the 76 00:04:28,680 --> 00:04:31,679 Speaker 1: sex part of it and goes straight to the next 77 00:04:31,720 --> 00:04:34,200 Speaker 1: bit in the life cycle and becomes this new polyp. 78 00:04:34,839 --> 00:04:37,640 Speaker 1: And I think this is so cool because it reminds 79 00:04:37,640 --> 00:04:40,680 Speaker 1: me of the imaginal cells that we talked about in 80 00:04:40,720 --> 00:04:44,599 Speaker 1: the Gremlin's podcast. We were talking about a butterfly sort 81 00:04:44,600 --> 00:04:48,400 Speaker 1: of deconstructing a rather caterpillar deconstructing itself in the cocoon, 82 00:04:49,040 --> 00:04:53,560 Speaker 1: and that those imaginal cells are much like undifferentiated stem cells, 83 00:04:53,600 --> 00:04:55,080 Speaker 1: and that they can do any sort of job that 84 00:04:55,120 --> 00:04:59,760 Speaker 1: they need to while reconstructing this new form, new life form, 85 00:04:59,800 --> 00:05:03,480 Speaker 1: this butterfly um and then those cells becoming specialized when 86 00:05:03,480 --> 00:05:06,440 Speaker 1: it when it actually does become the butterfly itself. This 87 00:05:06,520 --> 00:05:10,599 Speaker 1: is very much the same thing with this immortal jellyfish. Yeah, 88 00:05:10,680 --> 00:05:12,520 Speaker 1: to put it in the gremlin model now that we 89 00:05:12,560 --> 00:05:15,479 Speaker 1: brought gremlins and magua into it. Uh, the magua the 90 00:05:15,480 --> 00:05:18,479 Speaker 1: furry little dude, the gremlin, the repulsive creature that the 91 00:05:18,480 --> 00:05:22,040 Speaker 1: magua turns into. The gremlin is the adult form. The 92 00:05:22,080 --> 00:05:25,719 Speaker 1: magua is the juvenile form, maybe even a larval form. 93 00:05:25,720 --> 00:05:28,120 Speaker 1: However you want to look at it um and so 94 00:05:28,400 --> 00:05:31,120 Speaker 1: when you know, the magua eats after midnight, turns into 95 00:05:31,120 --> 00:05:34,240 Speaker 1: an adult gremlin. But then imagine if the adult gremlin 96 00:05:34,320 --> 00:05:39,320 Speaker 1: melted and then out of the gremlin melt emerged a magua. 97 00:05:39,520 --> 00:05:42,240 Speaker 1: You know, it would be a a reversal, you know. 98 00:05:42,320 --> 00:05:45,640 Speaker 1: So it's fascinating to think about about it that way, 99 00:05:45,640 --> 00:05:48,160 Speaker 1: but but still taking nothing away from this organism. Like 100 00:05:48,200 --> 00:05:51,600 Speaker 1: I said, it's not quite Benjamin Button, and it's which 101 00:05:51,800 --> 00:05:54,560 Speaker 1: is I think a good thing. Uh, it's also not 102 00:05:54,800 --> 00:05:57,479 Speaker 1: quite immortal. We're getting a little carried away with that, right, 103 00:05:57,520 --> 00:06:00,719 Speaker 1: there's a question mark to to what degree the tissues 104 00:06:00,800 --> 00:06:04,400 Speaker 1: can continue to regenerate themselves, right, Yeah, I mean it's 105 00:06:04,400 --> 00:06:08,159 Speaker 1: it's really awesome, it's really fascinating and certainly, um, something 106 00:06:08,279 --> 00:06:10,720 Speaker 1: very unique is going up. Well that's also another thing 107 00:06:10,720 --> 00:06:13,320 Speaker 1: because there's also the possibly there are other jellyfish species 108 00:06:13,320 --> 00:06:14,840 Speaker 1: that do this as well. So it's maybe not as 109 00:06:14,880 --> 00:06:16,599 Speaker 1: unique as some of the stories made it out to be. 110 00:06:16,800 --> 00:06:20,560 Speaker 1: But it's still pretty amazing. Uh. And ultimately how long 111 00:06:20,560 --> 00:06:23,960 Speaker 1: can this keep going? Uh? Probably not forever. This is 112 00:06:24,000 --> 00:06:26,520 Speaker 1: probably not a situation where it's like the Highlander of 113 00:06:26,600 --> 00:06:30,039 Speaker 1: jellyfish just carrying on and carrying on. Yeah, And let 114 00:06:30,120 --> 00:06:32,440 Speaker 1: me just do a quick quote from Pat Kraig again, 115 00:06:32,480 --> 00:06:36,599 Speaker 1: the marine biologist. Why it is significant? He or she 116 00:06:36,680 --> 00:06:39,080 Speaker 1: says that learning how to take adult cells and get 117 00:06:39,120 --> 00:06:41,360 Speaker 1: them back to the early stage where they can develop 118 00:06:41,400 --> 00:06:44,680 Speaker 1: into anything is a significant goal of what we want 119 00:06:44,720 --> 00:06:47,080 Speaker 1: to be able to achieve. Um, and I think in 120 00:06:47,080 --> 00:06:49,520 Speaker 1: this case she's talking about in humans, it's something that 121 00:06:49,600 --> 00:06:52,160 Speaker 1: this humble little jelly has a built in feature of 122 00:06:52,160 --> 00:06:55,080 Speaker 1: its life cycle. Things get gross around it, it melts 123 00:06:55,080 --> 00:06:57,040 Speaker 1: and rebuilds itself from scratch. So I think there is 124 00:06:57,040 --> 00:06:59,640 Speaker 1: definitely the potential that we could learn some basic things 125 00:06:59,720 --> 00:07:01,960 Speaker 1: that we could better apply to our own technology for 126 00:07:02,040 --> 00:07:04,400 Speaker 1: human medicine. Now, you know, it would be a dream 127 00:07:04,520 --> 00:07:06,960 Speaker 1: is to talk to Aubrey Degree about this, you know, 128 00:07:07,000 --> 00:07:09,279 Speaker 1: and say, like, what you know, to what extent are 129 00:07:09,360 --> 00:07:14,760 Speaker 1: things like this? These sort of discoveries um helpful in 130 00:07:14,760 --> 00:07:18,120 Speaker 1: in his own bio gerontology work where he is trying 131 00:07:18,160 --> 00:07:21,320 Speaker 1: to get to disease before it happens in the human 132 00:07:21,360 --> 00:07:24,720 Speaker 1: body and basically try to keep the body is finally 133 00:07:24,760 --> 00:07:29,000 Speaker 1: tuned as possible so that with drug intervention and good health, 134 00:07:29,160 --> 00:07:32,960 Speaker 1: we could possibly live, you know, upwards to five hundred 135 00:07:33,040 --> 00:07:36,480 Speaker 1: years old. Yeah. I guess one of the things about 136 00:07:36,560 --> 00:07:39,200 Speaker 1: humans is we don't really we never go through a 137 00:07:39,200 --> 00:07:43,600 Speaker 1: cocoon phase. We never go through a drastic of change. 138 00:07:43,800 --> 00:07:45,800 Speaker 1: I mean, you know, there's there's a lot of drastic 139 00:07:45,840 --> 00:07:48,400 Speaker 1: changes that go that occur between you know, being an 140 00:07:48,400 --> 00:07:51,560 Speaker 1: infinite being an adult, but but like what would be 141 00:07:51,560 --> 00:07:54,640 Speaker 1: the cut off line, you know, if you could? Yeah, 142 00:07:55,520 --> 00:07:58,240 Speaker 1: and to what degree could you re org your your 143 00:07:58,280 --> 00:08:01,640 Speaker 1: cells and your tissues. So I think that's the interesting part, 144 00:08:01,720 --> 00:08:07,800 Speaker 1: Like could we take that information and apply to yourselves practically? Yeah, 145 00:08:07,840 --> 00:08:10,920 Speaker 1: I mean what makes me think of the fly because 146 00:08:11,080 --> 00:08:13,440 Speaker 1: in a lot of primordial do in that. Yeah, I mean, 147 00:08:13,480 --> 00:08:15,280 Speaker 1: that's one of the things that the Jeff gold Blooms, 148 00:08:15,320 --> 00:08:17,760 Speaker 1: the character gets on about when he's you know, quote 149 00:08:17,840 --> 00:08:21,480 Speaker 1: unquote gold blooming about the excitement of the science, and 150 00:08:21,520 --> 00:08:24,960 Speaker 1: he's talking about, you know, being broken down in the 151 00:08:24,960 --> 00:08:28,880 Speaker 1: teleportation and then reassembled, reborn, re emerging from the plasma pool. 152 00:08:29,160 --> 00:08:32,800 Speaker 1: And that's pretty much what's happening with this jellyfish, which 153 00:08:32,880 --> 00:08:35,040 Speaker 1: I don't know. I mean, if you can combine that 154 00:08:35,400 --> 00:08:40,319 Speaker 1: with um quantum entanglement, which which we'll talk about, maybe 155 00:08:40,320 --> 00:08:42,680 Speaker 1: that could happen. But before we get to that, let's 156 00:08:42,720 --> 00:08:47,280 Speaker 1: talk about junk DNA or as we have discovered this year, 157 00:08:47,400 --> 00:08:50,440 Speaker 1: not so junk DNA. Yeah. So this is pretty cool, 158 00:08:50,480 --> 00:08:52,960 Speaker 1: And this is just another example of you knows, as 159 00:08:53,320 --> 00:08:55,959 Speaker 1: we any scientific endeavor, you'd you push a little a 160 00:08:56,040 --> 00:08:59,360 Speaker 1: little farther. You you answer one question and three new 161 00:08:59,400 --> 00:09:02,880 Speaker 1: ones arive. Um just this when you know you're you're 162 00:09:02,880 --> 00:09:06,360 Speaker 1: traveling across the countryside. Uh, what seems to be a 163 00:09:06,480 --> 00:09:09,040 Speaker 1: very simple array of hills and trees in the distance. 164 00:09:09,080 --> 00:09:10,960 Speaker 1: The closer you get you see the details, you see 165 00:09:11,000 --> 00:09:14,320 Speaker 1: the the how how complex the system actually is. And 166 00:09:14,400 --> 00:09:17,400 Speaker 1: so for the longest we've we've thought that there is 167 00:09:17,440 --> 00:09:21,520 Speaker 1: this thing called this junk DNA, which you know, sounds 168 00:09:21,960 --> 00:09:24,280 Speaker 1: kind of like a silly idea because why is it there? Right? 169 00:09:24,400 --> 00:09:27,079 Speaker 1: Is there's the the the you know, the quote you 170 00:09:27,080 --> 00:09:28,640 Speaker 1: may have seen on a T shirt. God don't make 171 00:09:28,640 --> 00:09:32,440 Speaker 1: no junk, right, So why would God? Because the idea 172 00:09:32,480 --> 00:09:35,800 Speaker 1: that the God in his his or her infinite wisdom 173 00:09:35,840 --> 00:09:38,160 Speaker 1: would not make something that was that was wasted, like 174 00:09:38,200 --> 00:09:41,280 Speaker 1: everything has a purpose, something, everything kind of fits in somehow. 175 00:09:41,720 --> 00:09:45,120 Speaker 1: And take the God out of that equation and fit 176 00:09:45,200 --> 00:09:48,760 Speaker 1: it into a more scientific setting, then it still rings 177 00:09:48,760 --> 00:09:50,760 Speaker 1: with a certain amount of true like it's there, like 178 00:09:50,800 --> 00:09:53,240 Speaker 1: why would why would there be junk DNA? Like would 179 00:09:53,280 --> 00:09:56,920 Speaker 1: it just be like leftover garbage DNA? And uh, you know, 180 00:09:57,040 --> 00:09:58,400 Speaker 1: the the take home here is that the more that 181 00:09:58,440 --> 00:10:00,920 Speaker 1: we've we've we've looked at with the vename, we realized 182 00:10:00,920 --> 00:10:03,080 Speaker 1: that it is not junk DNA, but it is a 183 00:10:03,080 --> 00:10:09,400 Speaker 1: genetic material that informs UM, these various epigenetic changes in 184 00:10:09,440 --> 00:10:12,240 Speaker 1: the genes that determine what genes are turned on or off. 185 00:10:12,559 --> 00:10:16,360 Speaker 1: And these switches, UM, the simplified way of looking at 186 00:10:16,360 --> 00:10:21,360 Speaker 1: these switches have an impact on various UM manifestations of 187 00:10:21,400 --> 00:10:25,439 Speaker 1: the human body, from various traits to UH diseases. Yeah, 188 00:10:25,520 --> 00:10:29,079 Speaker 1: and UM, this is a byproduct of mapping the human genome. 189 00:10:29,200 --> 00:10:32,760 Speaker 1: This discovery that junk DNA is not necessarily junking in 190 00:10:32,880 --> 00:10:36,839 Speaker 1: fact of it, they say, is vital and as you say, 191 00:10:36,840 --> 00:10:40,480 Speaker 1: it has UM has a pretty big implication in gene 192 00:10:40,480 --> 00:10:44,480 Speaker 1: switches that reside in bits of DNA. So UM, the 193 00:10:44,559 --> 00:10:48,720 Speaker 1: discovery is considered a major medical and scientific breakthrough and 194 00:10:48,800 --> 00:10:52,160 Speaker 1: it really does have an effect on our ability to 195 00:10:52,280 --> 00:10:56,960 Speaker 1: gain human health here. Um, and again we're talking about UM, 196 00:10:57,440 --> 00:11:00,760 Speaker 1: this material that was largely mysterious for this in some 197 00:11:00,800 --> 00:11:03,319 Speaker 1: ways it is, but there's an ability now to to 198 00:11:03,520 --> 00:11:06,760 Speaker 1: better uh look at it and try to figure out 199 00:11:06,760 --> 00:11:09,400 Speaker 1: what it is. In fact, the term junk DNA is 200 00:11:09,440 --> 00:11:11,520 Speaker 1: not being tossed around so much anymore. It has now 201 00:11:11,600 --> 00:11:15,400 Speaker 1: been upgraded to dark matter. Yes, something that and just 202 00:11:15,520 --> 00:11:19,720 Speaker 1: a briefly about dark matter in a cosmic sense, a mystery, 203 00:11:19,760 --> 00:11:22,760 Speaker 1: a thing that that we're we're not sure exactly on 204 00:11:22,800 --> 00:11:24,720 Speaker 1: the nature of, but we know it. It must be 205 00:11:24,760 --> 00:11:27,079 Speaker 1: important because there's a lot of it out there. Yeah, 206 00:11:27,200 --> 00:11:30,480 Speaker 1: and um, you know, there are complex diseases that appear 207 00:11:30,559 --> 00:11:34,120 Speaker 1: and they appear to be caused by tiny changes in 208 00:11:34,200 --> 00:11:37,240 Speaker 1: hundreds of genes switches which are controlled by this junk 209 00:11:37,360 --> 00:11:40,440 Speaker 1: or dark matter DNA. UM it really is a game 210 00:11:40,520 --> 00:11:43,760 Speaker 1: changer because it can help us to understand how alterations 211 00:11:43,760 --> 00:11:46,559 Speaker 1: in the non gene parts of DNA contribute to human disease, 212 00:11:46,600 --> 00:11:49,719 Speaker 1: which could lead to new drug therapy. UM. It could 213 00:11:49,760 --> 00:11:53,720 Speaker 1: also explain how the environment can affect disease risk. So 214 00:11:53,760 --> 00:11:56,560 Speaker 1: in the case of identical twins, small changes in the 215 00:11:56,640 --> 00:12:00,480 Speaker 1: environmental exposure can slightly altered genes, which is with the 216 00:12:00,520 --> 00:12:03,160 Speaker 1: result that one twin gets disease and the other does not. 217 00:12:04,080 --> 00:12:06,960 Speaker 1: UM and I think this is really going to be 218 00:12:07,520 --> 00:12:10,959 Speaker 1: most important, at least in the short term in cancer. 219 00:12:11,679 --> 00:12:14,960 Speaker 1: UM that this is from the New York Times article 220 00:12:15,040 --> 00:12:18,880 Speaker 1: Bits of Mystery DNA far from junk play crucial role. 221 00:12:19,480 --> 00:12:21,360 Speaker 1: It says that as they begin to turning the DNA 222 00:12:21,440 --> 00:12:25,800 Speaker 1: sequences of cancer cells. Researchers realize that most of the 223 00:12:25,880 --> 00:12:28,959 Speaker 1: thousands of DNA changes in cancer cells were not in genes. 224 00:12:29,040 --> 00:12:31,640 Speaker 1: They were in the dark matter. The challenge is to 225 00:12:31,640 --> 00:12:34,680 Speaker 1: figure out which of those changes are driving the cancer's growth. 226 00:12:34,920 --> 00:12:37,000 Speaker 1: All right, So there you go, junk DNA not so 227 00:12:37,080 --> 00:12:39,880 Speaker 1: junk after all. So we're gonna take a quick break 228 00:12:39,920 --> 00:12:42,640 Speaker 1: and when we come back, we're gonna roll through some 229 00:12:42,720 --> 00:12:56,520 Speaker 1: other potentially overlooked awesome science from the from including solar tornadoes. Okay, 230 00:12:56,600 --> 00:12:59,640 Speaker 1: we're back, and we are talking sellar tornadoes, which I'm 231 00:12:59,679 --> 00:13:04,280 Speaker 1: really excited about because this year they were confirmed. They've 232 00:13:04,280 --> 00:13:06,679 Speaker 1: been spotted or hints of them have been spotted in 233 00:13:06,720 --> 00:13:09,040 Speaker 1: two thousand and eight, but they were confirmed this year. 234 00:13:09,040 --> 00:13:12,000 Speaker 1: And it's thought that up to eleven thousand of them 235 00:13:12,240 --> 00:13:15,600 Speaker 1: twist over the Sun's surface every day, and they're made 236 00:13:15,640 --> 00:13:18,280 Speaker 1: of hot plasma and they are capable of reaching heights 237 00:13:18,280 --> 00:13:22,120 Speaker 1: of eighteen hundred miles high, with diameters ranging from nine 238 00:13:22,240 --> 00:13:27,600 Speaker 1: hundred and thirty to thirty five hundred miles wide. Okay, 239 00:13:27,640 --> 00:13:30,199 Speaker 1: so that the stats aren't done there, because think about 240 00:13:30,200 --> 00:13:33,920 Speaker 1: this mammoth um. It can spin upwards to about nine 241 00:13:33,960 --> 00:13:38,880 Speaker 1: thousand miles an hour, lasting only for about thirteen minutes each. Yeah, 242 00:13:39,000 --> 00:13:41,840 Speaker 1: and it's a lot of the news stories about this 243 00:13:42,240 --> 00:13:44,400 Speaker 1: really like the focus on these things are gonna be 244 00:13:44,400 --> 00:13:47,480 Speaker 1: as big as the United States. Yeah, they're They're enormous 245 00:13:47,920 --> 00:13:52,760 Speaker 1: solar tornadoes. Um, And it's important that I get a 246 00:13:52,760 --> 00:13:55,840 Speaker 1: lot of space related headlines. Don't at me because I 247 00:13:56,160 --> 00:13:59,880 Speaker 1: sometimes right for Discovery Space. So anytime Discovery Space does 248 00:13:59,880 --> 00:14:02,640 Speaker 1: a story, I end up seeing the headline. And it's 249 00:14:02,679 --> 00:14:04,600 Speaker 1: easy to become kind of dull to these after a 250 00:14:04,600 --> 00:14:07,760 Speaker 1: while because you have something happened in space, some new discovery. 251 00:14:08,080 --> 00:14:10,160 Speaker 1: You know, it's the nature of science journalism. You have 252 00:14:10,200 --> 00:14:13,120 Speaker 1: to spice it up a bit um. You know, black holes, 253 00:14:13,559 --> 00:14:16,040 Speaker 1: that's great, but no, it's not enough today. It's gotta 254 00:14:16,040 --> 00:14:18,560 Speaker 1: be monster black holes. There have to be cannibal black holes. 255 00:14:18,600 --> 00:14:23,480 Speaker 1: They've gotta so everything is sexed up to them. Yeah, 256 00:14:23,560 --> 00:14:26,920 Speaker 1: so solar tornadoes on the Sun. It sounds awesome, but 257 00:14:26,960 --> 00:14:28,920 Speaker 1: it was actually kind of easy to miss this one 258 00:14:28,960 --> 00:14:31,440 Speaker 1: if you're if you're having to process a lot of 259 00:14:31,600 --> 00:14:35,160 Speaker 1: space headlines because they kind of overstate everything. Even though 260 00:14:35,320 --> 00:14:37,640 Speaker 1: the core science is always really amazing when you look 261 00:14:37,680 --> 00:14:39,640 Speaker 1: at it. In this case, in point, you have the 262 00:14:39,800 --> 00:14:43,800 Speaker 1: solar tornadoes. Now you probably wonder, well, what is why 263 00:14:43,880 --> 00:14:45,400 Speaker 1: is it important? Like why does it what does it 264 00:14:45,440 --> 00:14:49,840 Speaker 1: matter that there are solar tornadoes aside from the cool factor, Well, 265 00:14:50,240 --> 00:14:52,560 Speaker 1: it really does give us a better understanding what's going 266 00:14:52,600 --> 00:14:56,000 Speaker 1: on on the Sun. Like one thing that it's important 267 00:14:56,040 --> 00:14:58,360 Speaker 1: to realize about the Sun is that the the surface 268 00:14:58,360 --> 00:15:01,120 Speaker 1: of the Sun is the coolest part of the Sun, 269 00:15:01,360 --> 00:15:04,920 Speaker 1: which seems to counterintuitive, right, right, especially since the atmosphere, 270 00:15:04,960 --> 00:15:07,280 Speaker 1: the weather of the Sun is hotter than the surface. 271 00:15:07,520 --> 00:15:08,880 Speaker 1: So it's like it's hot and then it gets a 272 00:15:08,880 --> 00:15:12,960 Speaker 1: little cooler and it gets progressively hotter again. Um and uh, 273 00:15:13,000 --> 00:15:14,920 Speaker 1: And this gives us little more reason to understand it 274 00:15:14,920 --> 00:15:17,280 Speaker 1: because in the atmosphere of the Sun, the weather of 275 00:15:17,040 --> 00:15:22,240 Speaker 1: the Sun, you have all this intense activity. Yeah and um, 276 00:15:22,280 --> 00:15:25,920 Speaker 1: I wanted to point out that then wide amount Boom, 277 00:15:26,000 --> 00:15:28,760 Speaker 1: he's an astrophysicist at the University of Also had said, 278 00:15:28,840 --> 00:15:30,680 Speaker 1: you know, we thought something was up. Basically, he said 279 00:15:30,680 --> 00:15:34,240 Speaker 1: that we observed some unusually hot plasma above the Sun's surface, 280 00:15:34,240 --> 00:15:36,200 Speaker 1: so we knew something was happening there, but we didn't 281 00:15:36,200 --> 00:15:39,520 Speaker 1: know what. And it turns out that this activity, these 282 00:15:39,680 --> 00:15:44,960 Speaker 1: solar tornadoes may contribute to that variation in heat. The 283 00:15:45,120 --> 00:15:47,320 Speaker 1: reason why there is so much heat in this upper 284 00:15:47,360 --> 00:15:51,240 Speaker 1: atmosphere because if you think about a tornado, it's um, 285 00:15:51,600 --> 00:15:55,080 Speaker 1: you know, it's well, there's there's a spiraling effect bringing 286 00:15:55,080 --> 00:15:58,000 Speaker 1: heat up right, But a sort of solar tornado is 287 00:15:58,080 --> 00:16:00,640 Speaker 1: unlike tornadoes on Earth, which of course are powered by 288 00:16:00,640 --> 00:16:03,760 Speaker 1: differences in temperature and humidity. UM. The twisters in the 289 00:16:03,760 --> 00:16:07,520 Speaker 1: Sun are a combination of hot flowing gas entangled magnetic 290 00:16:07,600 --> 00:16:12,400 Speaker 1: field lines, ultimately driven by nuclear reactions at the solar core. 291 00:16:13,040 --> 00:16:16,560 Speaker 1: So at the surface for the photosphere, cooled plasma sinks 292 00:16:16,600 --> 00:16:19,480 Speaker 1: towards the interior like water running down the bathtub drain, 293 00:16:20,000 --> 00:16:23,480 Speaker 1: and this creates vortex is that magnetic field lines are 294 00:16:23,480 --> 00:16:26,840 Speaker 1: forced to follow, and then the line stretch upward into 295 00:16:26,840 --> 00:16:30,400 Speaker 1: the chromosphere where they continue to spiral up. So it's 296 00:16:30,440 --> 00:16:33,320 Speaker 1: just one big death metal album up there. Big. Yeah. Yeah, 297 00:16:33,560 --> 00:16:37,640 Speaker 1: it's why you It's why the corona, this upper atmosphere 298 00:16:37,640 --> 00:16:40,760 Speaker 1: of the Sun's atmosphere is filled with all of this 299 00:16:40,920 --> 00:16:44,440 Speaker 1: heat because you have these massive tornadoes of plasma just 300 00:16:44,520 --> 00:16:47,920 Speaker 1: throwing themselves around. UM. And then as for the eleven 301 00:16:48,000 --> 00:16:51,640 Speaker 1: thousand per day statistic um. It has been said that 302 00:16:51,840 --> 00:16:54,520 Speaker 1: there may not be as many in the future because 303 00:16:55,000 --> 00:16:58,360 Speaker 1: we've seen a glut of these huge sillar tornadoes because 304 00:16:58,360 --> 00:17:00,600 Speaker 1: the Sun has been ramping up toward max and activity 305 00:17:00,680 --> 00:17:04,000 Speaker 1: levels in its current cycle. So you know, still it's 306 00:17:04,119 --> 00:17:08,400 Speaker 1: a tremendous amount of activity, and one that people weren't 307 00:17:08,400 --> 00:17:11,240 Speaker 1: necessarily aware of. They suspected, of course that something was 308 00:17:11,280 --> 00:17:13,520 Speaker 1: going on. But you know, I think it recasts the 309 00:17:13,560 --> 00:17:15,600 Speaker 1: whole idea of the Wizard of oz. I think someone 310 00:17:15,680 --> 00:17:20,679 Speaker 1: needs to to write with sort of the oz uh 311 00:17:20,920 --> 00:17:23,840 Speaker 1: based on the Sun. Really, so so Dorothy would go 312 00:17:23,880 --> 00:17:26,960 Speaker 1: to the Sun instead. Yes, there's there are a lot 313 00:17:27,000 --> 00:17:29,680 Speaker 1: of logistics to be worked out there. But imagine the 314 00:17:29,680 --> 00:17:32,000 Speaker 1: twister that comes through that cancel. Yes, yeah, of course, 315 00:17:32,040 --> 00:17:34,679 Speaker 1: of course, the solar twister. I like it. I like it, 316 00:17:34,720 --> 00:17:37,600 Speaker 1: all right, all right, well, now let's turn our attention 317 00:17:37,800 --> 00:17:41,360 Speaker 1: to the quantum world. Now, of course, quantum things happened 318 00:17:41,359 --> 00:17:45,920 Speaker 1: in because quantum, quantum happens. Quantum happens. It looks great 319 00:17:45,920 --> 00:17:49,359 Speaker 1: in the headline um and so there there continues to 320 00:17:49,400 --> 00:17:52,720 Speaker 1: be some interesting headway in the field of quantum teleportation. 321 00:17:53,600 --> 00:17:56,960 Speaker 1: Now I know what you're you're you're you're wondering. You're 322 00:17:57,000 --> 00:18:00,000 Speaker 1: either wondering, well, what is quantum teleportation or you're thinking, 323 00:18:00,080 --> 00:18:03,199 Speaker 1: oh God, I hope they don't try and explain it. Uh. 324 00:18:03,840 --> 00:18:06,160 Speaker 1: And we're we're not going to go to in depth 325 00:18:06,240 --> 00:18:10,280 Speaker 1: on quantum teleportation. That's really a subject for another time, 326 00:18:10,359 --> 00:18:12,080 Speaker 1: but but we can sort of speed you through the 327 00:18:12,119 --> 00:18:15,399 Speaker 1: simple version of it um because what what we have here, 328 00:18:15,440 --> 00:18:18,680 Speaker 1: what we're dealing with, essentially, is quantum entanglement, in which 329 00:18:18,720 --> 00:18:21,960 Speaker 1: two sub atomic particles thousands of light years of party 330 00:18:22,000 --> 00:18:26,200 Speaker 1: and then can instantly respond um to each other's motions. Uh. 331 00:18:26,240 --> 00:18:29,000 Speaker 1: So we've this started off is something that was you know, 332 00:18:29,040 --> 00:18:33,240 Speaker 1: merely theoretical that we figured was possible, and then scientists 333 00:18:33,280 --> 00:18:37,000 Speaker 1: observed the phenomenon at at at the particle level and 334 00:18:37,119 --> 00:18:38,960 Speaker 1: uh and in two thousand and nine they managed to 335 00:18:39,240 --> 00:18:43,800 Speaker 1: produce the effect with linked superconductors and uh. And it's 336 00:18:43,800 --> 00:18:46,840 Speaker 1: an exciting topic because you know, it helps us certainly, 337 00:18:47,000 --> 00:18:49,080 Speaker 1: it involves a greater understanding of what's going on in 338 00:18:49,080 --> 00:18:53,680 Speaker 1: the quantum realm, but also it has enormous possible applications, 339 00:18:54,080 --> 00:18:57,800 Speaker 1: uh for faster than light signaling, for as sending data, 340 00:18:57,880 --> 00:19:01,040 Speaker 1: for encrypting data, um but particularly and in the in 341 00:19:01,040 --> 00:19:04,840 Speaker 1: the area of quantum computing. It's it's pretty big medicine. Yeah. 342 00:19:04,840 --> 00:19:06,919 Speaker 1: In the past year, a team from China and another 343 00:19:06,960 --> 00:19:10,520 Speaker 1: in Austria set new records for quantum teleportation using a 344 00:19:10,640 --> 00:19:13,720 Speaker 1: laser to beam photons through the open air over sixty 345 00:19:13,800 --> 00:19:17,199 Speaker 1: and eighty nine excuse me, sixty and eighty nine miles 346 00:19:17,200 --> 00:19:21,320 Speaker 1: respectively for context, just you know, just to let you know. 347 00:19:21,560 --> 00:19:24,000 Speaker 1: The first efforts to do this resulted in sending the 348 00:19:24,040 --> 00:19:28,080 Speaker 1: particles mirror inches. So the fact that they're already up 349 00:19:28,119 --> 00:19:32,960 Speaker 1: to eighty nine miles is pretty amazing. So the idea 350 00:19:33,160 --> 00:19:36,359 Speaker 1: is that quantum teleportation could be used to transmit particles 351 00:19:36,359 --> 00:19:41,240 Speaker 1: and information from an orbiting satellite eventually to relay station 352 00:19:41,280 --> 00:19:44,800 Speaker 1: on Earth. So this information in the process by which 353 00:19:44,800 --> 00:19:49,600 Speaker 1: it is transmitted is what is called quantum encryption. So, 354 00:19:49,680 --> 00:19:53,000 Speaker 1: according to wire dot COM's article the Race to bring 355 00:19:53,080 --> 00:19:57,760 Speaker 1: Quantum Teleportation to your world, quote, if developed, quantum teleportation, 356 00:19:57,800 --> 00:20:02,080 Speaker 1: satellites could allow spies to pass large amounts of information 357 00:20:02,119 --> 00:20:06,040 Speaker 1: back and forth or create unhackable codes. Should we ever 358 00:20:06,080 --> 00:20:10,760 Speaker 1: build quantum computers, they would need quantum teleporters in order 359 00:20:10,800 --> 00:20:14,160 Speaker 1: to be networked together in a quantum version of the Internet. 360 00:20:14,920 --> 00:20:17,480 Speaker 1: This is very cool stuff, you know, just from a 361 00:20:17,560 --> 00:20:22,119 Speaker 1: sci fi perspective, you can imagine the implications of a 362 00:20:22,240 --> 00:20:26,199 Speaker 1: quantum infrastructure in our world. Yes, to say nothing of 363 00:20:26,200 --> 00:20:28,920 Speaker 1: all those scenarios in which got vaculate might wear address. 364 00:20:32,240 --> 00:20:34,760 Speaker 1: So that's sort of the Pine the Sky idea. And 365 00:20:34,800 --> 00:20:36,720 Speaker 1: if you think that's too pine the sky though, just 366 00:20:36,880 --> 00:20:39,679 Speaker 1: consider this. China plans to launch a satellite with a 367 00:20:39,800 --> 00:20:45,640 Speaker 1: quantum teleportation experiment payload in two, with a quantum communications 368 00:20:45,640 --> 00:20:50,240 Speaker 1: project being estimated to cost fifty to one million dollars. Okay, 369 00:20:50,280 --> 00:20:54,040 Speaker 1: so China obviously thinks that this is an important technology. Uh. 370 00:20:54,080 --> 00:21:00,760 Speaker 1: Europe UM, UH, Japan and Canada are all their space 371 00:21:00,760 --> 00:21:03,880 Speaker 1: agencies are hoping to fund their own quantum teleportation satellite 372 00:21:03,920 --> 00:21:06,480 Speaker 1: projects in the coming years. So the US is a 373 00:21:06,520 --> 00:21:08,439 Speaker 1: bit behind in this, and some of this has to 374 00:21:08,480 --> 00:21:13,800 Speaker 1: do with bureaucratic shuffling between DARPA and IOPA. UM. But 375 00:21:14,600 --> 00:21:17,959 Speaker 1: it's interesting because it's definitely a race to get as 376 00:21:18,000 --> 00:21:20,800 Speaker 1: advanced in this technology as possible. Yeah, if you think 377 00:21:20,800 --> 00:21:24,480 Speaker 1: back to the episode we did on an interseller Internet 378 00:21:24,560 --> 00:21:28,119 Speaker 1: the idea and the interplanetary Internet. Uh, because as we 379 00:21:29,280 --> 00:21:31,359 Speaker 1: as we continue to expand out into the cosmos. If 380 00:21:31,400 --> 00:21:33,520 Speaker 1: we you know, as we we show up on other worlds, 381 00:21:33,520 --> 00:21:35,840 Speaker 1: we're gonna have to deal with communication, and we're going 382 00:21:35,880 --> 00:21:39,640 Speaker 1: to face the reality that we're dealing with such distances 383 00:21:39,680 --> 00:21:43,520 Speaker 1: that that instantaneous communication just isn't possible. So you end 384 00:21:43,560 --> 00:21:46,080 Speaker 1: up with it with ever growing lag times, and it's 385 00:21:46,119 --> 00:21:48,120 Speaker 1: more of a return to an age of instead of 386 00:21:48,440 --> 00:21:51,920 Speaker 1: you know, instantly connecting with a loved one or or 387 00:21:52,320 --> 00:21:55,520 Speaker 1: or just employers or mission team members, you would have 388 00:21:55,600 --> 00:21:57,680 Speaker 1: to send off missives into the void and then wait 389 00:21:57,720 --> 00:21:59,680 Speaker 1: for one to return and you know, hope that nothing 390 00:21:59,720 --> 00:22:02,600 Speaker 1: went long. One of the big exciting things, here's the 391 00:22:02,640 --> 00:22:08,760 Speaker 1: possible possibility of instantaneous communication between planets by use of 392 00:22:08,880 --> 00:22:12,720 Speaker 1: this quantum teleportation. And it's because we're talking about data 393 00:22:12,920 --> 00:22:17,360 Speaker 1: being reproduced in one place through quantum entanglement. No, it's 394 00:22:17,400 --> 00:22:19,800 Speaker 1: it's very interesting and I particularly that the spy part 395 00:22:19,800 --> 00:22:22,440 Speaker 1: of course, just kind of makes me sit up a 396 00:22:22,440 --> 00:22:26,480 Speaker 1: little bit taller and take notice. And there was an interesting, 397 00:22:26,840 --> 00:22:31,040 Speaker 1: uh analogy of this of how this might happen with 398 00:22:31,200 --> 00:22:34,720 Speaker 1: quantum teleportation to send this controllable signal, say to a 399 00:22:34,800 --> 00:22:37,439 Speaker 1: satellite and I'm going to take a stab at it, 400 00:22:37,520 --> 00:22:40,040 Speaker 1: a game for it. Yeah, let's do it. Okay. This 401 00:22:40,119 --> 00:22:45,000 Speaker 1: requires three subatomic particles, say photons. In this case, two 402 00:22:45,000 --> 00:22:48,199 Speaker 1: of the photons are entangled with one another, and the 403 00:22:48,359 --> 00:22:52,480 Speaker 1: third contains the bit of information you want to send. Okay. 404 00:22:52,920 --> 00:22:56,239 Speaker 1: So just know that the sub atomic particles, let's say 405 00:22:56,320 --> 00:22:59,879 Speaker 1: they're a vertical orientation, okay. And once you test that 406 00:23:00,000 --> 00:23:01,800 Speaker 1: and you figure out that these the two that are 407 00:23:01,880 --> 00:23:04,200 Speaker 1: entangled are vertical. You know, the other ones in vertical 408 00:23:04,280 --> 00:23:07,080 Speaker 1: no matter where it is in conjunction to the other one. Okay, 409 00:23:07,080 --> 00:23:10,679 Speaker 1: So these are like paired Dakota rings. Yes, So you 410 00:23:10,760 --> 00:23:13,399 Speaker 1: take one and I take one. Yeah, okay, And then 411 00:23:13,440 --> 00:23:16,280 Speaker 1: there's that third bit right that has the information. So 412 00:23:16,600 --> 00:23:18,480 Speaker 1: it says. For a simple example of how this works, 413 00:23:18,560 --> 00:23:21,080 Speaker 1: let's say you place one photon from the entangled pair 414 00:23:21,240 --> 00:23:24,879 Speaker 1: in Los Angeles and the other in New York. In 415 00:23:25,000 --> 00:23:28,119 Speaker 1: Los Angeles, a scientist measures one of the entangled photons 416 00:23:28,520 --> 00:23:31,440 Speaker 1: and the third particle at the same time. She doesn't 417 00:23:31,480 --> 00:23:34,640 Speaker 1: find out their exact properties, but just their relative ones 418 00:23:34,800 --> 00:23:37,480 Speaker 1: if they are the same or opposite of one another, 419 00:23:38,040 --> 00:23:40,800 Speaker 1: for instance. And the particles get destroyed during this measurement. 420 00:23:41,160 --> 00:23:44,160 Speaker 1: So the scientists has measured figures out. Let's say it's horizontal. 421 00:23:44,280 --> 00:23:46,760 Speaker 1: Let's say that she discovers that the particles are opposites, 422 00:23:47,040 --> 00:23:50,840 Speaker 1: meaning that the one that is entangled, Okay, that the 423 00:23:50,840 --> 00:23:53,679 Speaker 1: one of the pair is opposite from the third particle. 424 00:23:53,760 --> 00:23:56,359 Speaker 1: That bit of information, they're opposite from each other. And 425 00:23:56,400 --> 00:23:58,919 Speaker 1: she relays this information to her New York colleague. He 426 00:23:59,040 --> 00:24:03,000 Speaker 1: then measures the entangled photon and knows that the opposite 427 00:24:03,080 --> 00:24:05,639 Speaker 1: of that measurement is the bit of information he was 428 00:24:05,640 --> 00:24:09,040 Speaker 1: meant to receive. Yeah, there you go, clear as clear, 429 00:24:10,840 --> 00:24:13,719 Speaker 1: clear as is mud. Right there. Um. It makes me 430 00:24:13,960 --> 00:24:17,040 Speaker 1: we ran across a number of different quote unquote simplified 431 00:24:17,040 --> 00:24:19,040 Speaker 1: explanations for this stuff. When we're looking at it, like 432 00:24:19,080 --> 00:24:22,840 Speaker 1: there's one that involves like a secret like police investigation 433 00:24:22,920 --> 00:24:27,760 Speaker 1: involving detectives, Romulus and Remus and Alice. It it gets 434 00:24:27,840 --> 00:24:29,920 Speaker 1: very complex even when you're trying to do a very 435 00:24:29,920 --> 00:24:33,560 Speaker 1: simple explanation, and a lot of it kept. It kept. 436 00:24:33,560 --> 00:24:37,200 Speaker 1: Made me think of the movie Labyrinth in which uh 437 00:24:37,320 --> 00:24:40,399 Speaker 1: Sarah encounters the two doors with the with the the 438 00:24:40,480 --> 00:24:44,399 Speaker 1: muppety creatures behind them, where one of them says that 439 00:24:43,840 --> 00:24:46,960 Speaker 1: they both informer that one of them always tells the truth, 440 00:24:46,960 --> 00:24:49,879 Speaker 1: and one of them always lies. And then one tells 441 00:24:49,880 --> 00:24:51,879 Speaker 1: her you know what the other one would say, and 442 00:24:51,920 --> 00:24:53,440 Speaker 1: you have to try and work out in your mind 443 00:24:54,680 --> 00:24:56,959 Speaker 1: what that answer means and which doors you should take 444 00:24:57,000 --> 00:24:59,880 Speaker 1: based on that answer, and it's it's really a mind work. Well, 445 00:25:00,119 --> 00:25:02,480 Speaker 1: the problem with a Romulus and Remus example that we 446 00:25:02,520 --> 00:25:05,760 Speaker 1: did not talk about for a good reason is because 447 00:25:05,760 --> 00:25:08,639 Speaker 1: it also brings cultural drink into the conversation. That's not 448 00:25:08,680 --> 00:25:11,600 Speaker 1: relevant to it, right, because Romulus and Remus is an 449 00:25:11,680 --> 00:25:15,160 Speaker 1: entirely different thing. All they wanted in this analogy were twins. 450 00:25:15,640 --> 00:25:19,200 Speaker 1: Yeah yeah, um so, but I got to attach their characters. 451 00:25:19,200 --> 00:25:22,160 Speaker 1: They had to name them. Suddenly they were invested in them, 452 00:25:22,160 --> 00:25:24,000 Speaker 1: and we're just trying to understand plans. All I want 453 00:25:24,000 --> 00:25:26,760 Speaker 1: to know is this entangled pair, how are they behaving? 454 00:25:26,840 --> 00:25:30,119 Speaker 1: And what is their behavior? Tell us about this third particle? Right, 455 00:25:30,320 --> 00:25:32,479 Speaker 1: don't kind of distract us by telling a good story, right, 456 00:25:32,760 --> 00:25:35,439 Speaker 1: good stuff? Um, but it's it's again. This is uh, 457 00:25:35,520 --> 00:25:38,679 Speaker 1: this cryptography, right, This this key that is inserted to 458 00:25:38,720 --> 00:25:41,199 Speaker 1: give you a bit of information, and this essentially is 459 00:25:41,200 --> 00:25:44,760 Speaker 1: what these entangled pairs are doing. Real quick, just to 460 00:25:45,040 --> 00:25:47,440 Speaker 1: mention another story that we discussed briefly, but we ended 461 00:25:47,480 --> 00:25:50,320 Speaker 1: up not including. There was a really cool article about 462 00:25:50,480 --> 00:25:54,199 Speaker 1: dissonant music and what happens when animals listen to it, 463 00:25:54,480 --> 00:25:57,719 Speaker 1: or more importantly, what's what happens when people listen to it? 464 00:25:58,080 --> 00:26:00,439 Speaker 1: And this is a u c l A team that 465 00:26:00,480 --> 00:26:05,359 Speaker 1: looked into this, and they found that that just distorted 466 00:26:05,400 --> 00:26:09,240 Speaker 1: and jarring music is really is so evocative because the 467 00:26:09,280 --> 00:26:13,280 Speaker 1: mechanisms are closely related to distress calls in animals. So 468 00:26:13,480 --> 00:26:16,560 Speaker 1: the idea here is that everyone, like you know, perks 469 00:26:16,640 --> 00:26:18,879 Speaker 1: up at Woodstock and listens to Jimi Hendrix playing the 470 00:26:18,960 --> 00:26:24,000 Speaker 1: national anthem because it's jarring and there's distortion, and you know, 471 00:26:24,040 --> 00:26:28,760 Speaker 1: it calls out to our our deeper animal selves. So 472 00:26:29,320 --> 00:26:31,359 Speaker 1: I found that found it interesting and they were also 473 00:26:31,400 --> 00:26:32,920 Speaker 1: they also did some studies in like two thousand and 474 00:26:32,960 --> 00:26:37,040 Speaker 1: ten where they're looking at and classic movies and various 475 00:26:37,160 --> 00:26:40,720 Speaker 1: genres including horror and looking at UH at the soundtracks 476 00:26:40,760 --> 00:26:42,920 Speaker 1: and how they differ and the kind of emotions they evoked. 477 00:26:43,240 --> 00:26:45,280 Speaker 1: And and they did see that like horror films tended 478 00:26:45,320 --> 00:26:50,520 Speaker 1: to to use more screaming females and distorted vocals UH 479 00:26:50,720 --> 00:26:55,040 Speaker 1: distorted sounds in their soundtracks. Um So anyway, I just 480 00:26:55,080 --> 00:26:56,800 Speaker 1: found it's, like said, there's not a lot of meat 481 00:26:56,880 --> 00:26:58,679 Speaker 1: really there to chew on. But it's interesting to think 482 00:26:58,720 --> 00:27:01,080 Speaker 1: about that in terms of of music that we find. 483 00:27:01,359 --> 00:27:03,560 Speaker 1: Please maybe they did a study and and uh and everything. 484 00:27:03,560 --> 00:27:06,080 Speaker 1: We're like, you know, subjects were rating music that they 485 00:27:06,119 --> 00:27:09,760 Speaker 1: listened to, uh on a negative and positive scale. They 486 00:27:09,760 --> 00:27:11,679 Speaker 1: were listening to stuff that was distorted and stuff that 487 00:27:11,760 --> 00:27:14,879 Speaker 1: was more you know, serene and uh and more melody 488 00:27:14,920 --> 00:27:16,840 Speaker 1: to it. Uh and it. But it did make me 489 00:27:16,880 --> 00:27:19,440 Speaker 1: think about music that combines both because they're certainly there's 490 00:27:19,440 --> 00:27:21,719 Speaker 1: straight up noise music you can listen to straight up 491 00:27:21,760 --> 00:27:25,080 Speaker 1: you know, just extreme electronic distortion and stuff that sounds 492 00:27:25,560 --> 00:27:28,720 Speaker 1: uh in my wife's words, like someone throwing a xylophone 493 00:27:28,720 --> 00:27:31,080 Speaker 1: down a set of stairs. And then you have you know, 494 00:27:31,119 --> 00:27:32,760 Speaker 1: more stuff that's all the way on the on the 495 00:27:32,760 --> 00:27:34,720 Speaker 1: serene level. But then you have music that sort of 496 00:27:34,720 --> 00:27:37,240 Speaker 1: incorporates both, like like some of the groups that I 497 00:27:37,280 --> 00:27:39,800 Speaker 1: really like that that toy with the nose, that the 498 00:27:39,880 --> 00:27:44,440 Speaker 1: nose the noise uh section here, like like Autecker. They 499 00:27:44,480 --> 00:27:47,840 Speaker 1: they use a certain amount of serene and sounds and 500 00:27:47,880 --> 00:27:50,120 Speaker 1: a certain amount of melody, but then also a lot 501 00:27:50,160 --> 00:27:54,760 Speaker 1: of you know, unpredictable um uh, distorted noise as well, 502 00:27:55,119 --> 00:27:56,679 Speaker 1: and it sort of comes together in this sort of 503 00:27:56,680 --> 00:27:59,240 Speaker 1: interesting place that that it makes you think, what's it's 504 00:27:59,280 --> 00:28:01,600 Speaker 1: touching based with the you know, the part of my 505 00:28:01,640 --> 00:28:04,440 Speaker 1: mind it wants, you know, calmness and serenity, but also 506 00:28:04,520 --> 00:28:07,000 Speaker 1: in this this animal part of my mind that is 507 00:28:07,040 --> 00:28:10,000 Speaker 1: responding to something that might be the sound of an 508 00:28:10,040 --> 00:28:13,800 Speaker 1: animal dying. Yeah, it's stimulating, right, So it's interesting to 509 00:28:13,840 --> 00:28:16,800 Speaker 1: have both of those um I also wanted to mention, 510 00:28:16,920 --> 00:28:20,080 Speaker 1: and I don't have the information right in front of me, 511 00:28:20,200 --> 00:28:21,960 Speaker 1: so this is off top of my head. I believe 512 00:28:22,040 --> 00:28:25,280 Speaker 1: it was a chimp in Germany, a zoo in Germany. 513 00:28:25,280 --> 00:28:31,800 Speaker 1: Have you heard about this chump um That was remarkable 514 00:28:31,960 --> 00:28:36,040 Speaker 1: for a couple of things, but mainly because he would 515 00:28:36,800 --> 00:28:40,480 Speaker 1: take rocks, put them nearby him, and then sit there 516 00:28:40,520 --> 00:28:44,280 Speaker 1: and wait for zoo visitors to come by and will 517 00:28:44,360 --> 00:28:48,640 Speaker 1: be act very relaxed, and then just when when the 518 00:28:48,800 --> 00:28:53,080 Speaker 1: zoo visitor sort of didn't realize or was distracted by something, 519 00:28:53,280 --> 00:28:56,040 Speaker 1: with launch an attack with those rocks. And I thought 520 00:28:56,040 --> 00:28:59,240 Speaker 1: it was fascinating because not only does it show premeditative behavior, 521 00:28:59,240 --> 00:29:02,120 Speaker 1: which we know systin animals, particularly in chimps, but it 522 00:29:02,200 --> 00:29:06,600 Speaker 1: shows the ability for these chimps to actually enter into 523 00:29:06,640 --> 00:29:10,040 Speaker 1: the realm of acting and in order to pull off 524 00:29:10,040 --> 00:29:14,960 Speaker 1: this subterfuge against these zoo visitors. And uh, the video 525 00:29:15,000 --> 00:29:17,400 Speaker 1: on it is fascinating. I thought that was an interesting 526 00:29:17,440 --> 00:29:20,680 Speaker 1: bit of animal behavior from this year. All right, well, 527 00:29:20,680 --> 00:29:23,720 Speaker 1: there you go, just some overlooked, potentially overlooked, but really 528 00:29:23,720 --> 00:29:27,280 Speaker 1: cool bits of science from that we wanted to clean 529 00:29:27,360 --> 00:29:30,920 Speaker 1: up there and present to you. So let's call over 530 00:29:31,120 --> 00:29:36,120 Speaker 1: the robit for a little listener mail. Before I read 531 00:29:36,160 --> 00:29:37,720 Speaker 1: some of these, I do want to point out real quick. 532 00:29:38,040 --> 00:29:41,320 Speaker 1: In a previous episode, I mentioned pugs, the breed of dog, 533 00:29:41,560 --> 00:29:44,200 Speaker 1: and I talked about how useless they were, uh, you know, 534 00:29:44,240 --> 00:29:46,720 Speaker 1: because the largely you encounter a pug, and the pug 535 00:29:46,800 --> 00:29:49,320 Speaker 1: is just this slightly you know, this kind of poorly 536 00:29:49,840 --> 00:29:52,640 Speaker 1: put together dog that has trouble with with heat and 537 00:29:52,680 --> 00:29:56,600 Speaker 1: too much exercise and is ultimately just a lap creature. Uh. 538 00:29:57,040 --> 00:29:58,240 Speaker 1: Or at least that's the way I used to think 539 00:29:58,240 --> 00:30:01,400 Speaker 1: about it. But just yesterday I was on Marta, Atlanta's 540 00:30:01,440 --> 00:30:03,800 Speaker 1: public transportation system. I saw a young lady in a 541 00:30:03,840 --> 00:30:07,040 Speaker 1: wheelchair and she had a helper animal that was a pug, 542 00:30:07,400 --> 00:30:10,520 Speaker 1: So it's recast your opinion. I have to come back 543 00:30:10,560 --> 00:30:12,240 Speaker 1: some of what I thought about pugs, because here's a 544 00:30:12,280 --> 00:30:14,560 Speaker 1: pug and he's uh. I think it was a she actually, 545 00:30:14,560 --> 00:30:17,320 Speaker 1: But there was that pug and she was doing her job, 546 00:30:17,440 --> 00:30:20,400 Speaker 1: representing calmly there by the by the wheelchair as a 547 00:30:20,440 --> 00:30:23,600 Speaker 1: train roared by. So how did you know she was she? Well, 548 00:30:23,640 --> 00:30:26,120 Speaker 1: I mean I could sort of. She was slim, so 549 00:30:26,160 --> 00:30:28,000 Speaker 1: you could sort of tell what was going on under there. 550 00:30:28,640 --> 00:30:29,880 Speaker 1: You know. It's like you picked the dog up and 551 00:30:29,880 --> 00:30:32,400 Speaker 1: turned her over the idea I rolled her Alpha roll 552 00:30:32,640 --> 00:30:34,880 Speaker 1: the dog. No, it's always a no no. Don't alpha 553 00:30:35,000 --> 00:30:40,360 Speaker 1: roll a helper an, especially on public transportation. Exactly. All right, Well, um, 554 00:30:40,400 --> 00:30:42,520 Speaker 1: here's a little bit of listener mail from our listener Brad. 555 00:30:42,960 --> 00:30:46,040 Speaker 1: Brad writes and says, hey, you guys are awesome. I 556 00:30:46,080 --> 00:30:48,520 Speaker 1: am at a party right now. And that's the thing. 557 00:30:48,560 --> 00:30:50,640 Speaker 1: This first time anyone has written this from a party 558 00:30:50,720 --> 00:30:53,080 Speaker 1: that they've mentioned it. But he says, I am at 559 00:30:53,080 --> 00:30:55,000 Speaker 1: a party right now, and it was just plugging your 560 00:30:55,040 --> 00:30:58,520 Speaker 1: biology of Gremlin's episode. The crowd here were so excited. 561 00:30:58,960 --> 00:31:01,880 Speaker 1: We got to pondering the biology of zombies. Hint, you 562 00:31:01,920 --> 00:31:04,080 Speaker 1: need to do an episode on the biology of zombies. 563 00:31:04,160 --> 00:31:07,400 Speaker 1: That's all I'm gonna say, Bratt. I don't know what 564 00:31:07,400 --> 00:31:09,560 Speaker 1: I have to think about that one. The potential there, 565 00:31:09,880 --> 00:31:12,000 Speaker 1: I know there are some. I mean, it ultimately comes 566 00:31:12,000 --> 00:31:15,840 Speaker 1: down to are their real world biological analogs? Because that 567 00:31:15,920 --> 00:31:18,840 Speaker 1: was the fun of the Gremlins, was taking something that 568 00:31:19,320 --> 00:31:22,520 Speaker 1: seems wacky and stupid and totally just made up without 569 00:31:22,560 --> 00:31:25,480 Speaker 1: any real regard for the natural world and pairing it 570 00:31:25,560 --> 00:31:29,960 Speaker 1: with things in the natural world that are just as amazing. Um, 571 00:31:30,000 --> 00:31:32,720 Speaker 1: And I think there's some parallels with zombies we'd have 572 00:31:32,760 --> 00:31:34,840 Speaker 1: we'd have to explore. Speaking of have you seen a 573 00:31:34,880 --> 00:31:37,880 Speaker 1: trailer for the Zombies Love Story movie that's coming out? 574 00:31:39,840 --> 00:31:42,960 Speaker 1: Telling is it? Does it look good? Yeah? Somehow they well, 575 00:31:43,000 --> 00:31:44,600 Speaker 1: I don't know, it looks kind of hokey too, because 576 00:31:44,640 --> 00:31:48,000 Speaker 1: somehow the zombies seem to heal themselves through the powerful 577 00:31:48,000 --> 00:31:50,880 Speaker 1: of If I was actually paying attention to this trailer, 578 00:31:51,080 --> 00:31:54,360 Speaker 1: um in a meaningful way, but we might be interesting, 579 00:31:54,360 --> 00:31:56,520 Speaker 1: all right, We'll look out for that one. We also 580 00:31:56,560 --> 00:31:59,760 Speaker 1: received a number of cool contents from people who listen 581 00:31:59,800 --> 00:32:02,200 Speaker 1: to our teen Angst episode, we were talking about the 582 00:32:02,960 --> 00:32:04,840 Speaker 1: the science of teen ankst. Well, what's going on with 583 00:32:04,840 --> 00:32:07,840 Speaker 1: the teenager's brain? Why? Why did teenagers seem so different? 584 00:32:07,960 --> 00:32:11,600 Speaker 1: And why as teenagers do we feel ultimately so different 585 00:32:11,600 --> 00:32:14,640 Speaker 1: about the world and about our social life than uh, 586 00:32:14,640 --> 00:32:16,320 Speaker 1: than we did when we were younger, and then we 587 00:32:16,360 --> 00:32:19,000 Speaker 1: do when we get older. So we heard from a 588 00:32:19,040 --> 00:32:22,240 Speaker 1: number of people. Here's one from listener Jordan's. Jordan rights 589 00:32:22,280 --> 00:32:24,120 Speaker 1: in and says, Hey, they're just finished listening to your 590 00:32:24,120 --> 00:32:26,520 Speaker 1: podcast on teenage angst. I just wanted to let you 591 00:32:26,560 --> 00:32:29,200 Speaker 1: know that, being a teenager myself, I have experienced some 592 00:32:29,240 --> 00:32:31,600 Speaker 1: of these tricks the mind plays, but most of the 593 00:32:31,640 --> 00:32:33,800 Speaker 1: time I can overcome the brain's way of tricking me. 594 00:32:34,120 --> 00:32:37,000 Speaker 1: Like when one of my friends desired, uh that he 595 00:32:37,200 --> 00:32:39,880 Speaker 1: no longer be my friend, I myself didn't care, but 596 00:32:39,920 --> 00:32:43,120 Speaker 1: I started having bad dreams about this non friend of mine, 597 00:32:43,480 --> 00:32:45,440 Speaker 1: and I would wake up and I would think to myself, 598 00:32:45,600 --> 00:32:48,120 Speaker 1: I don't really care care. Why is this person's Why 599 00:32:48,160 --> 00:32:50,840 Speaker 1: is it so important to me? Thanks for explaining this 600 00:32:50,920 --> 00:32:53,880 Speaker 1: to me. Keep up the great podcasting work. Regards Jordan's. 601 00:32:53,960 --> 00:32:56,520 Speaker 1: We heard from Drake. Drake wrote in says, hello, I 602 00:32:56,600 --> 00:32:59,800 Speaker 1: just listened to your Teenage Teenager podcast and was interested 603 00:32:59,800 --> 00:33:03,480 Speaker 1: in a change of consciousness. I was absorbed in all 604 00:33:03,520 --> 00:33:06,000 Speaker 1: of the facts that you guys stated because in a 605 00:33:06,000 --> 00:33:08,400 Speaker 1: few months, I too will know what, uh what it's 606 00:33:08,440 --> 00:33:10,600 Speaker 1: like to be a teenager. I used to think that 607 00:33:10,840 --> 00:33:13,400 Speaker 1: taking risk and rebellion were just things that teens did 608 00:33:13,720 --> 00:33:15,680 Speaker 1: to fit in or to look cool, But now I 609 00:33:15,720 --> 00:33:18,480 Speaker 1: know that there's some science behind it. Besides, I never 610 00:33:18,520 --> 00:33:20,800 Speaker 1: really knew how to fit in any way. Keep up 611 00:33:20,840 --> 00:33:23,240 Speaker 1: the great work, and I'm happy you've got this message. 612 00:33:23,680 --> 00:33:26,720 Speaker 1: And that's from Drake from Nevada. So we received a 613 00:33:26,760 --> 00:33:28,440 Speaker 1: number of other comments and it's all I wish we 614 00:33:28,480 --> 00:33:31,200 Speaker 1: could read them all. Um. A lot of the cool 615 00:33:31,280 --> 00:33:35,760 Speaker 1: moments where people either were reevaluating the teenagers they were 616 00:33:35,960 --> 00:33:38,480 Speaker 1: or took a close look at the teenagers they were becoming, 617 00:33:38,920 --> 00:33:41,320 Speaker 1: also wanted to mention. We got an email from Isabelle 618 00:33:41,400 --> 00:33:45,640 Speaker 1: and she took us to task for not exploring teens 619 00:33:45,720 --> 00:33:50,040 Speaker 1: who exercise great amounts of self control, because she said 620 00:33:50,040 --> 00:33:54,560 Speaker 1: that she believes that there are a good subsection here 621 00:33:54,800 --> 00:34:00,000 Speaker 1: of teenagers who are honest and who um, who can 622 00:34:00,040 --> 00:34:03,000 Speaker 1: kind of control their states of rebellion and so on 623 00:34:03,080 --> 00:34:04,560 Speaker 1: and so forth, and I thought, you know, she makes 624 00:34:04,560 --> 00:34:07,560 Speaker 1: a really interesting point, and that might make for a 625 00:34:07,560 --> 00:34:10,240 Speaker 1: good podcast in the future here talking about self control 626 00:34:10,239 --> 00:34:14,480 Speaker 1: and teenagers and why some teenagers are successful at that. Um, Like, 627 00:34:14,560 --> 00:34:16,839 Speaker 1: ultimately we could do like a how to guide for 628 00:34:16,840 --> 00:34:20,680 Speaker 1: for teenagers, the teenager the teenage brain owners guide. Yeah, like, 629 00:34:20,800 --> 00:34:23,560 Speaker 1: what you know, is it higher functioning? Why are some 630 00:34:23,600 --> 00:34:26,120 Speaker 1: teenagers more mature than others? Because I certainly thought of 631 00:34:26,360 --> 00:34:29,120 Speaker 1: examples of teenagers I know in my life who are 632 00:34:30,239 --> 00:34:33,400 Speaker 1: who do seem very responsible and have a good amount 633 00:34:33,400 --> 00:34:35,680 Speaker 1: of self control. So I thought she's got a point there, 634 00:34:36,320 --> 00:34:38,560 Speaker 1: perhaps something we can pursue here in the future. Yeah. Well, 635 00:34:38,600 --> 00:34:40,680 Speaker 1: I was talking about this episode with with my wife 636 00:34:40,680 --> 00:34:42,600 Speaker 1: and she brought up to that It's like, it's kind 637 00:34:42,640 --> 00:34:45,759 Speaker 1: of a little disturbing to think about how the the 638 00:34:45,920 --> 00:34:48,840 Speaker 1: range in which one has the teenage brain. You know, 639 00:34:48,880 --> 00:34:50,840 Speaker 1: it can it can hit pretty early, and then it 640 00:34:50,880 --> 00:34:52,839 Speaker 1: can it can also hit kind of late and last 641 00:34:52,920 --> 00:34:55,560 Speaker 1: up until you know, basically in mid twenties. And at 642 00:34:55,600 --> 00:34:58,200 Speaker 1: that point, like we we were already sitting and sending 643 00:34:58,800 --> 00:35:02,600 Speaker 1: these individuals to to college, We're already sending these individuals 644 00:35:02,600 --> 00:35:05,799 Speaker 1: to war. Um, you know that they're they're voting. I mean, 645 00:35:05,840 --> 00:35:08,320 Speaker 1: they're all these these things that are happening and uh 646 00:35:08,400 --> 00:35:10,960 Speaker 1: and but there's still you know, potentially in this uh, 647 00:35:11,280 --> 00:35:14,560 Speaker 1: this state of development. So yeah, Well, we also got 648 00:35:14,560 --> 00:35:16,520 Speaker 1: an email and just thinking about that that have different 649 00:35:16,520 --> 00:35:18,799 Speaker 1: states and experiences that teenagers going through.
