WEBVTT - Marshall Brain's News Roundup No. 2

0:00:00.520 --> 0:00:03.600
<v Speaker 1>Welcome to brain Stuff from how stuff Works dot com

0:00:03.600 --> 0:00:14.640
<v Speaker 1>where smart Happens. Hi, I'm Marshall Brain and this is

0:00:14.760 --> 0:00:19.120
<v Speaker 1>episode two of Friday's science and tech news round up.

0:00:19.680 --> 0:00:22.520
<v Speaker 1>As you may recall, last Friday was the first time

0:00:22.560 --> 0:00:25.040
<v Speaker 1>I did this, and I asked you for your comments,

0:00:25.640 --> 0:00:27.880
<v Speaker 1>and wow, did I get a lot of comments. There were.

0:00:28.560 --> 0:00:30.680
<v Speaker 1>There were hundreds of them. It was. It was really

0:00:30.680 --> 0:00:34.279
<v Speaker 1>pretty amazing and I did try to respond to as

0:00:34.320 --> 0:00:36.280
<v Speaker 1>many of them as I could, but after the first

0:00:36.360 --> 0:00:38.320
<v Speaker 1>hundred or so, I just ran out of time. And

0:00:38.360 --> 0:00:41.400
<v Speaker 1>I apologize if I wasn't able to personally respond to you,

0:00:41.840 --> 0:00:45.519
<v Speaker 1>but thanks so much for sending them in, and I

0:00:45.560 --> 0:00:47.960
<v Speaker 1>will try to use several of the suggestions I got

0:00:48.000 --> 0:00:51.560
<v Speaker 1>today in doing this. If you'd like to comment more,

0:00:52.000 --> 0:00:55.240

<v Speaker 1>try to respond and and thank you again. I really

0:01:14.760 --> 0:01:18.200
<v Speaker 1>appreciate it. So let's look at the news what happened

0:01:18.200 --> 0:01:21.119
<v Speaker 1>this week. If I had to pick the most interesting thing,

0:01:21.319 --> 0:01:24.560
<v Speaker 1>I saw on the web this week. Keeping in mind

0:01:24.600 --> 0:01:28.039
<v Speaker 1>that I'm a robotics kind of guy, it's the fact

0:01:28.080 --> 0:01:32.240
<v Speaker 1>that the I Tripoli Magazines I Tripoli Spectrum did an

0:01:32.319 --> 0:01:36.800
<v Speaker 1>article on David Hansen's robot heads. Now, Hanson has been

0:01:36.800 --> 0:01:40.160
<v Speaker 1>working on these things for for maybe as much as

0:01:40.160 --> 0:01:43.759
<v Speaker 1>a decade. I know, back in like two thousand three

0:01:43.840 --> 0:01:46.360
<v Speaker 1>or something, Popular Science did a big article on it.

0:01:46.440 --> 0:01:48.600
<v Speaker 1>So he's been working at this for a long time,

0:01:49.320 --> 0:01:54.840
<v Speaker 1>and they are getting so realistic. It really is amazing. Um.

0:01:54.880 --> 0:01:56.200
<v Speaker 1>You know, if you want to look at one of

0:01:56.200 --> 0:01:58.440
<v Speaker 1>these heads, you can go to Google right now and

0:01:58.520 --> 0:02:02.840
<v Speaker 1>you can type in interest reading number six eight four

0:02:03.400 --> 0:02:06.960
<v Speaker 1>and the top link will be my article that contains

0:02:06.960 --> 0:02:09.480
<v Speaker 1>a link to the video, and you look at it,

0:02:09.840 --> 0:02:14.359
<v Speaker 1>and like I said, Hansen's heads are getting very very close.

0:02:14.680 --> 0:02:18.280
<v Speaker 1>The blinking isn't quite there yet, but otherwise just wow.

0:02:18.760 --> 0:02:23.040
<v Speaker 1>I envision one day walking into like a favorite restaurant

0:02:23.120 --> 0:02:27.000
<v Speaker 1>chain with Lee and this very attractive man or woman

0:02:27.280 --> 0:02:31.640
<v Speaker 1>comes up, acting as a Greater and says like, hi, Marshall,

0:02:31.919 --> 0:02:33.800
<v Speaker 1>it's great to have you here. How are the kids?

0:02:34.240 --> 0:02:37.000
<v Speaker 1>And she will be a robot. I'll be able to

0:02:37.000 --> 0:02:39.560
<v Speaker 1>walk into any restaurant in the chain, and I will

0:02:39.600 --> 0:02:43.440
<v Speaker 1>be recognized because all these robots will share the same database,

0:02:43.520 --> 0:02:46.359
<v Speaker 1>and they'll use facial recognition and they'll be able to talk.

0:02:46.440 --> 0:02:49.920
<v Speaker 1>And you know, when you look at the heads that

0:02:49.919 --> 0:02:53.800
<v Speaker 1>that Hanson is creating, it's not that hard to imagine

0:02:53.880 --> 0:02:57.160
<v Speaker 1>it happening in the not too distant future. We got

0:02:57.280 --> 0:03:00.440
<v Speaker 1>to get the natural language processing figure year doubt, and

0:03:00.520 --> 0:03:03.520
<v Speaker 1>we have to get some of the mechanics of walking

0:03:03.560 --> 0:03:07.440
<v Speaker 1>and stuff made more fluid. But it's coming. It's coming,

0:03:07.440 --> 0:03:10.320
<v Speaker 1>and it just wasn't It was really interesting to look

0:03:10.360 --> 0:03:14.520
<v Speaker 1>at how realistic the heads are. So a lot of

0:03:14.560 --> 0:03:16.720
<v Speaker 1>you commented that I need to do some kind of

0:03:16.760 --> 0:03:21.280
<v Speaker 1>separator between stories because it was a little confusing last time.

0:03:21.400 --> 0:03:25.880
<v Speaker 1>So here's the separator flip. You might remember the Icelandic

0:03:25.960 --> 0:03:29.400
<v Speaker 1>volcano that erupted last year. It became famous because it

0:03:29.520 --> 0:03:32.600
<v Speaker 1>totally shut down the airlines in Europe. You may remember

0:03:33.000 --> 0:03:35.560
<v Speaker 1>nothing was flying. They couldn't fly in Europe and they

0:03:35.560 --> 0:03:39.480
<v Speaker 1>couldn't fly between Europe and the United States because of

0:03:39.520 --> 0:03:42.520
<v Speaker 1>the ash that that volcano threw up. The ash would

0:03:42.520 --> 0:03:46.120
<v Speaker 1>get into jet engines and destroy them. So now there's

0:03:46.200 --> 0:03:50.640
<v Speaker 1>evidence in the form of a swarm of earthquakes, that

0:03:50.680 --> 0:03:53.520
<v Speaker 1>there may be another eruption coming up, and it could

0:03:53.600 --> 0:03:56.960
<v Speaker 1>be a lot bigger than the last one. Uh. That

0:03:57.120 --> 0:04:00.760
<v Speaker 1>article is linked in Interesting Reading them or six eighty

0:04:00.760 --> 0:04:04.680
<v Speaker 1>four as well, and it contains this cool quote. The

0:04:04.800 --> 0:04:09.720
<v Speaker 1>last recorded eruption of whatever the name of this volcano is,

0:04:09.720 --> 0:04:12.600
<v Speaker 1>because I can't pronounce it, but let's say it's Barta

0:04:12.600 --> 0:04:18.960
<v Speaker 1>Bunga was in nineteen ten, although volcanologists believe its last

0:04:19.080 --> 0:04:22.800
<v Speaker 1>major eruption occurred in fourteen seventy seven, when it produced

0:04:22.839 --> 0:04:27.320
<v Speaker 1>a large ash and plumas fallout. It also produced the

0:04:27.440 --> 0:04:31.760
<v Speaker 1>largest known lava flow during the past ten thousand years

0:04:31.760 --> 0:04:34.600
<v Speaker 1>on Earth. That's a lot of lava, especially if you've

0:04:34.640 --> 0:04:38.200
<v Speaker 1>ever seen the volcano that's been erupting on Hawaii for

0:04:38.680 --> 0:04:42.520
<v Speaker 1>you know forever, it's produced a lot of lava. And

0:04:42.600 --> 0:04:45.960
<v Speaker 1>to think that this was the largest known lava flow

0:04:46.120 --> 0:04:49.200
<v Speaker 1>in ten thousand years is an incredible amount of lava.

0:04:49.320 --> 0:04:53.120
<v Speaker 1>So if that volcano blows, we may never fly to

0:04:53.160 --> 0:04:56.480
<v Speaker 1>Europe again. For all I know. That article was published

0:04:56.480 --> 0:05:02.719
<v Speaker 1>by the Telegraph. Blip. We now know how fleas are

0:05:02.880 --> 0:05:05.400
<v Speaker 1>able to jump so far. Now. I don't know if

0:05:05.400 --> 0:05:08.520
<v Speaker 1>you've ever experienced fleas, or if you've even ever seen

0:05:08.560 --> 0:05:11.440
<v Speaker 1>a flea jump, and it may not seem like such

0:05:11.480 --> 0:05:13.920
<v Speaker 1>a big deal if you never have, but the jumping

0:05:13.960 --> 0:05:18.200
<v Speaker 1>ability of fleas is utterly amazing when you consider their size.

0:05:18.880 --> 0:05:21.960
<v Speaker 1>I'm gonna admit that I haven't seen a flea in years,

0:05:22.080 --> 0:05:26.080
<v Speaker 1>but that's only because someone invented those flea drops that

0:05:26.120 --> 0:05:29.440
<v Speaker 1>you put on the back of the dog, and they work.

0:05:29.520 --> 0:05:32.200
<v Speaker 1>Those flea drops work incredibly well and they get rid

0:05:32.240 --> 0:05:35.760
<v Speaker 1>of all fleas. But before those drops were invented, I

0:05:35.880 --> 0:05:39.040
<v Speaker 1>used to live on a farm in Zebula, North Carolina,

0:05:39.160 --> 0:05:42.080
<v Speaker 1>and I had eight dogs and they would bring fleas

0:05:42.120 --> 0:05:47.200
<v Speaker 1>into the house, obviously, especially in the summer. And you've

0:05:47.240 --> 0:05:49.520
<v Speaker 1>got a lot of experience with fleas and they really

0:05:49.520 --> 0:05:52.680
<v Speaker 1>are amazing. Or if you've ever seen um some of

0:05:52.720 --> 0:05:55.760
<v Speaker 1>the studies on fleas and flea circuses and stuff, that

0:05:56.040 --> 0:05:58.839
<v Speaker 1>they're they're cool bugs if you don't mind the fact

0:05:58.880 --> 0:06:02.640
<v Speaker 1>that they suck your blood. Anyway, the way these fleas

0:06:02.880 --> 0:06:06.919
<v Speaker 1>jump is that they have what's essentially a spring mechanism,

0:06:06.960 --> 0:06:10.920
<v Speaker 1>and the leg muscle doesn't drive the leg directly, It

0:06:11.040 --> 0:06:14.640
<v Speaker 1>loads up the spring and then releases it. And that

0:06:14.880 --> 0:06:18.040
<v Speaker 1>springs release is what drives the leg and lets the

0:06:18.560 --> 0:06:22.800
<v Speaker 1>fleas jump so far, and the leg has this cool

0:06:23.120 --> 0:06:26.680
<v Speaker 1>kind of multipart lever system that makes the most of

0:06:26.720 --> 0:06:29.840
<v Speaker 1>that spring. So they figured all this out by taking

0:06:29.880 --> 0:06:35.600
<v Speaker 1>these really nice high speed slow motion movies of fleas

0:06:35.720 --> 0:06:38.280
<v Speaker 1>jumping and kind of reverse engineering what was going on.

0:06:38.440 --> 0:06:41.800
<v Speaker 1>So again, if you google interesting reading numbers six eight four,

0:06:41.839 --> 0:06:44.040
<v Speaker 1>you can find an article that has a video showing

0:06:44.640 --> 0:06:48.039
<v Speaker 1>fleas jumping. And you know, I guess you could go

0:06:48.080 --> 0:06:51.039
<v Speaker 1>out and this summer get your dog to bring you

0:06:51.080 --> 0:06:52.920
<v Speaker 1>some fleas and you can watch them do their thing.

0:06:52.960 --> 0:06:57.920
<v Speaker 1>It truly is amazing. Blip. You may have heard that

0:06:58.080 --> 0:07:02.120
<v Speaker 1>Russian scientists have been down in Antarctica this summer, and yes,

0:07:02.160 --> 0:07:05.280
<v Speaker 1>it's summer in Antarctica right now, because that's the Southern Hemisphere,

0:07:05.640 --> 0:07:08.599
<v Speaker 1>and they're trying to drill a borehole through the ice

0:07:08.880 --> 0:07:14.800
<v Speaker 1>to reach an ancient ice entombed lake that's underneath Antarctica,

0:07:14.920 --> 0:07:17.880
<v Speaker 1>and they're hoping to find cool new life forms there

0:07:18.200 --> 0:07:20.800
<v Speaker 1>because this lake has been cut off from everything else

0:07:21.000 --> 0:07:25.280
<v Speaker 1>they think for something like fourteen million years. So they've

0:07:25.320 --> 0:07:28.920
<v Speaker 1>been drilling through the ice more than two miles now

0:07:29.080 --> 0:07:33.440
<v Speaker 1>all summer long, trying to get down into the water

0:07:33.520 --> 0:07:37.160
<v Speaker 1>of this lake, and they're like a hundred feet from

0:07:37.200 --> 0:07:40.160
<v Speaker 1>breaking through and getting to the lake. And they ran

0:07:40.200 --> 0:07:42.920
<v Speaker 1>out of time because summer's ending, and if they were

0:07:42.960 --> 0:07:45.560
<v Speaker 1>to stay there too long, it gets so cold you

0:07:45.600 --> 0:07:48.440
<v Speaker 1>can't take off and land airplanes anymore because it freezes

0:07:48.480 --> 0:07:51.080
<v Speaker 1>up the hydraulic fluid and stuff. And so they had

0:07:51.120 --> 0:07:54.360
<v Speaker 1>to get out. So before they left, they filled this

0:07:54.560 --> 0:07:58.320
<v Speaker 1>two mile deep borehole with kerosene, hopped on their plane

0:07:58.320 --> 0:08:01.240
<v Speaker 1>and took off. The rasine was put there to keep

0:08:01.280 --> 0:08:04.400
<v Speaker 1>the whole from closing back up, so that, you know,

0:08:04.400 --> 0:08:06.440
<v Speaker 1>they don't have to go and redrill the whole thing

0:08:07.000 --> 0:08:09.520
<v Speaker 1>next year, because it took the whole summer to drill it,

0:08:09.560 --> 0:08:12.120
<v Speaker 1>so they need to be able to start with with

0:08:12.480 --> 0:08:15.760
<v Speaker 1>a partially done whole. But as you can imagine, there's

0:08:15.760 --> 0:08:17.880
<v Speaker 1>a lot of people who just are not happy about

0:08:17.960 --> 0:08:21.240
<v Speaker 1>the kerosene. What if the kerosene contaminates the lake, what

0:08:21.360 --> 0:08:24.520
<v Speaker 1>if you know, who knows what else. So you know,

0:08:24.560 --> 0:08:27.480
<v Speaker 1>there are international bodies that worry about this kind of stuff,

0:08:27.480 --> 0:08:30.000
<v Speaker 1>and we'll see how this plays out over the next year.

0:08:31.000 --> 0:08:35.200
<v Speaker 1>Blip Reuters published an article that says that Facebook and

0:08:35.280 --> 0:08:39.160
<v Speaker 1>Google are considering the idea of buying Twitter. The thing

0:08:39.200 --> 0:08:42.520
<v Speaker 1>that's most amazing about the article is the price. It's

0:08:42.559 --> 0:08:46.840
<v Speaker 1>as high as ten billion dollars for Twitter. Just to

0:08:46.880 --> 0:08:50.840
<v Speaker 1>put that into perspective, that's like what that's like two

0:08:50.880 --> 0:08:54.160
<v Speaker 1>hours of the Iraqi war. Okay, that's a bad analogy,

0:08:54.200 --> 0:08:57.040
<v Speaker 1>but let's put it in a different perspective. Think about

0:08:57.800 --> 0:09:00.920
<v Speaker 1>all of the factories and all of the employees and

0:09:01.120 --> 0:09:04.800
<v Speaker 1>all the stuff that General Motors has to have in

0:09:04.960 --> 0:09:09.880
<v Speaker 1>order to be a worldwide company making, you know, millions

0:09:09.920 --> 0:09:17.440
<v Speaker 1>of automobiles. It's a huge, unbelievable, complicated, a massive company.

0:09:17.559 --> 0:09:21.120
<v Speaker 1>That company, if they were to sell a hundred thousand

0:09:21.280 --> 0:09:25.440
<v Speaker 1>Chevy Vaults at forty tho dollars each, that transaction alone,

0:09:25.559 --> 0:09:30.000
<v Speaker 1>that one model alone, that's four billion dollars. GM is

0:09:30.040 --> 0:09:34.480
<v Speaker 1>a massive company. That company is only worth fifty billion

0:09:34.520 --> 0:09:37.920
<v Speaker 1>dollars in market cap, and Forward is about the same.

0:09:38.720 --> 0:09:43.120
<v Speaker 1>So you have Twitter, which is little hundred and forty

0:09:43.200 --> 0:09:46.400
<v Speaker 1>character messages that people randomly flip off to each other,

0:09:47.000 --> 0:09:50.520
<v Speaker 1>and you have GM, which forges cars and trucks out

0:09:50.520 --> 0:09:53.920
<v Speaker 1>of steel and aluminum to drive the nation or whatever.

0:09:54.520 --> 0:09:57.280
<v Speaker 1>Yet GM is worth not that much more than Twitter.

0:09:57.400 --> 0:10:01.120
<v Speaker 1>It's just it's amazing. So what does this mean? Think

0:10:01.120 --> 0:10:04.240
<v Speaker 1>about it? What does this mean? This means that we

0:10:04.320 --> 0:10:08.199
<v Speaker 1>need to get out there and start us some websites. Wow,

0:10:08.280 --> 0:10:11.280
<v Speaker 1>we we need to be creating websites because who knows

0:10:11.679 --> 0:10:14.880
<v Speaker 1>what the next Twitter like idea will be or where

0:10:14.920 --> 0:10:17.719
<v Speaker 1>it will come from. You know, it's just not that

0:10:17.800 --> 0:10:22.000
<v Speaker 1>complicated an idea to be worth that kind of money,

0:10:22.160 --> 0:10:27.440
<v Speaker 1>and it indicates that we should be creating websites. Blip

0:10:27.960 --> 0:10:30.280
<v Speaker 1>I did a podcast about this a couple of months ago,

0:10:30.679 --> 0:10:33.480
<v Speaker 1>but it broke into the mainstream news this week. So

0:10:33.559 --> 0:10:36.520
<v Speaker 1>let me let me just mention it again. A scientist

0:10:36.600 --> 0:10:39.960
<v Speaker 1>has developed what is being called a thinking cap or

0:10:40.040 --> 0:10:45.480
<v Speaker 1>a creativity cap that can enhance your creative abilities by

0:10:45.520 --> 0:10:50.080
<v Speaker 1>disrupting your left hemisphere. So think about some of the

0:10:50.120 --> 0:10:53.880
<v Speaker 1>things savants can do. Like, you know, you've probably seen

0:10:54.920 --> 0:10:58.560
<v Speaker 1>this with certain autistic people. You can, you know, drop

0:10:58.559 --> 0:11:00.360
<v Speaker 1>a box of matches on the floor, or and they

0:11:00.360 --> 0:11:03.840
<v Speaker 1>can instantly count all the matches just by looking at

0:11:03.840 --> 0:11:07.120
<v Speaker 1>it one time. Or they can draw incredibly well, or

0:11:07.160 --> 0:11:10.200
<v Speaker 1>they have photographic memories, or they can solve complex math

0:11:10.280 --> 0:11:14.200
<v Speaker 1>problems in their head. Most normal people can't do this

0:11:14.360 --> 0:11:18.320
<v Speaker 1>kind of stuff, But it turns out maybe we actually can.

0:11:18.760 --> 0:11:22.880
<v Speaker 1>And what this thinking cap or creativity cap does is

0:11:23.000 --> 0:11:26.880
<v Speaker 1>it gets in and disrupts part of the left hemisphere

0:11:27.000 --> 0:11:31.319
<v Speaker 1>for a period of time like an hour, and these

0:11:31.360 --> 0:11:35.560
<v Speaker 1>abilities get uncovered in normal people. It's almost like the

0:11:35.679 --> 0:11:40.599
<v Speaker 1>left hemisphere is masking them or or making these abilities,

0:11:41.400 --> 0:11:44.520
<v Speaker 1>uh be suppressed. And once you get the left hemisphere

0:11:44.520 --> 0:11:49.479
<v Speaker 1>out of the picture, prestoh, these magical abilities become available

0:11:49.520 --> 0:11:53.120
<v Speaker 1>to normal people. So one professor who's working on this

0:11:53.160 --> 0:11:57.200
<v Speaker 1>project calls it the biggest cognitive enhancement we are aware of.

0:11:57.920 --> 0:12:01.760
<v Speaker 1>And you know, this could become a commercial product in

0:12:01.960 --> 0:12:04.959
<v Speaker 1>the not too distant future because this isn't like you know,

0:12:05.040 --> 0:12:07.600
<v Speaker 1>it doesn't require a machine the size of a skyscraper

0:12:07.640 --> 0:12:09.800
<v Speaker 1>or anything like that. It's a really pretty simple device.

0:12:10.360 --> 0:12:12.800
<v Speaker 1>So it's something you know, maybe we can buy it

0:12:12.840 --> 0:12:16.960
<v Speaker 1>at Best Buy in in two years or something like that. Blip.

0:12:17.520 --> 0:12:20.680
<v Speaker 1>There was a lot of stuff about tablet computers this week.

0:12:21.000 --> 0:12:24.920
<v Speaker 1>The biggest announcement probably is from HP, which released its

0:12:24.960 --> 0:12:29.360
<v Speaker 1>new touch pad tablet. So last week there were only

0:12:29.559 --> 0:12:35.400
<v Speaker 1>three major tablet operating systems. There was Apples, there was Android,

0:12:35.440 --> 0:12:39.200
<v Speaker 1>and there was Windows seven. So this week the hp

0:12:39.240 --> 0:12:42.840
<v Speaker 1>product makes a completely new operating system available, and this

0:12:42.880 --> 0:12:45.840
<v Speaker 1>one is called web os, which was developed by Palm

0:12:46.360 --> 0:12:48.880
<v Speaker 1>and hp bot. Palm last year in order to get

0:12:48.880 --> 0:12:53.440
<v Speaker 1>web os the demos that you can find on YouTube

0:12:53.720 --> 0:12:56.840
<v Speaker 1>or you know, on on the brain stuff blog. There's

0:12:56.840 --> 0:13:00.120
<v Speaker 1>a lot of videos out. They look pretty interesting and

0:13:00.160 --> 0:13:03.319
<v Speaker 1>will know probably in a year whether this operating system

0:13:03.440 --> 0:13:06.800
<v Speaker 1>is able to get any traction and take off. Meanwhile,

0:13:07.160 --> 0:13:11.640
<v Speaker 1>the iPad two has apparently gone into production in preparation

0:13:11.720 --> 0:13:16.080
<v Speaker 1>for its announcements sometime this spring. Apple has sold something

0:13:16.120 --> 0:13:20.080
<v Speaker 1>like fifteen million of the original iPads, or more than

0:13:20.120 --> 0:13:22.880
<v Speaker 1>a million a month, so it needs to start production

0:13:23.000 --> 0:13:25.800
<v Speaker 1>long before the announcement in order to get enough new

0:13:25.920 --> 0:13:30.520
<v Speaker 1>iPads into the pipeline to meet demand. Once the announcement happens,

0:13:31.000 --> 0:13:33.520
<v Speaker 1>of course, the new one's thinner, and it'll have a

0:13:33.600 --> 0:13:36.440
<v Speaker 1>camera for FaceTime on the front of it, and the

0:13:36.480 --> 0:13:40.320
<v Speaker 1>CPU gets upgraded. But you know, it's not that much

0:13:40.360 --> 0:13:43.720
<v Speaker 1>different from the existing iPad. It certainly can't jump as

0:13:43.720 --> 0:13:46.920
<v Speaker 1>far as a flea can or anything like that. Blip

0:13:47.480 --> 0:13:51.240
<v Speaker 1>Wired wrote about a piece of performance art that is

0:13:51.280 --> 0:13:55.840
<v Speaker 1>really pretty original. Two people donate their white blood cells

0:13:56.040 --> 0:13:58.600
<v Speaker 1>and then those white blood cells battle it out in

0:13:58.640 --> 0:14:01.640
<v Speaker 1>an arena under a my groscope to see who has

0:14:01.720 --> 0:14:05.240
<v Speaker 1>the stronger immune system. This is not quite as easy

0:14:05.280 --> 0:14:07.760
<v Speaker 1>as it sounds, because you have to have somebody draw blood,

0:14:07.800 --> 0:14:10.199
<v Speaker 1>and then the white blood cells need to be isolated

0:14:10.679 --> 0:14:13.720
<v Speaker 1>from the red blood cells and and put aside, and

0:14:13.760 --> 0:14:15.760
<v Speaker 1>then they need to be stained with a color so

0:14:15.840 --> 0:14:18.480
<v Speaker 1>you know which team is winning and which team is losing.

0:14:18.920 --> 0:14:22.200
<v Speaker 1>But you have to admit that it's a pretty interesting

0:14:22.240 --> 0:14:24.800
<v Speaker 1>way for two people to have a competition, and then

0:14:25.040 --> 0:14:27.240
<v Speaker 1>you know the winner can go on and and fight

0:14:27.280 --> 0:14:31.440
<v Speaker 1>with somebody else. You can imagine Obama versus Putin or

0:14:31.520 --> 0:14:35.800
<v Speaker 1>something coming up in the future. Blip. NASA is getting

0:14:35.840 --> 0:14:39.120
<v Speaker 1>ready to design another new rocket, but it's arguing with

0:14:39.200 --> 0:14:42.360
<v Speaker 1>Congress right now about the cost of that new rocket.

0:14:42.800 --> 0:14:45.160
<v Speaker 1>And as you may recall, NASA is about to have

0:14:45.240 --> 0:14:48.920
<v Speaker 1>its last Shuttle flight, and last year NASA had its

0:14:48.960 --> 0:14:52.440
<v Speaker 1>first test flight of its Constellation rocket that was going

0:14:52.520 --> 0:14:55.760
<v Speaker 1>to replace the Shuttle in terms of getting people into orbit,

0:14:56.280 --> 0:14:59.440
<v Speaker 1>but the Constellation program was cut with the hope that

0:14:59.520 --> 0:15:03.200
<v Speaker 1>private companies can pick up the slack. The other rocket

0:15:03.240 --> 0:15:05.960
<v Speaker 1>that NASA needs to build is a heavy lift vehicle

0:15:06.080 --> 0:15:09.520
<v Speaker 1>because the Shuttle was good at getting big stuff into orbit.

0:15:10.000 --> 0:15:13.000
<v Speaker 1>This heavy lift rocket would use many of the parts

0:15:13.040 --> 0:15:15.880
<v Speaker 1>from the Shuttle, including the solid rocket boosters and the

0:15:15.880 --> 0:15:19.480
<v Speaker 1>Shuttle's main engines, in order to cut the costs. But

0:15:19.640 --> 0:15:22.320
<v Speaker 1>NASA still isn't sure that it has enough money to

0:15:22.360 --> 0:15:26.600
<v Speaker 1>bring this thing into into flight status. We should be

0:15:26.640 --> 0:15:30.280
<v Speaker 1>able to see the results of their calculations by this summer,

0:15:30.760 --> 0:15:33.960
<v Speaker 1>and if the money is available, the new rocket is

0:15:34.000 --> 0:15:37.520
<v Speaker 1>supposed to have test flights in five years. Speaking of

0:15:37.520 --> 0:15:40.920
<v Speaker 1>the Shuttle, there's been some discussion of letting a private

0:15:41.000 --> 0:15:44.160
<v Speaker 1>company take over the Shuttle after it retires so that

0:15:44.200 --> 0:15:48.520
<v Speaker 1>it can keep flying. A company called United Space Alliance

0:15:48.640 --> 0:15:51.720
<v Speaker 1>already is in charge of the thousands of people who

0:15:51.800 --> 0:15:55.480
<v Speaker 1>process shuttles for flight and launch them. This company would

0:15:55.480 --> 0:15:58.920
<v Speaker 1>take over and fly the Shuttle as a private enterprise,

0:15:59.040 --> 0:16:01.480
<v Speaker 1>rather than seeing it of balled. It might be a

0:16:01.520 --> 0:16:04.720
<v Speaker 1>win win for both the employees of that company and

0:16:04.880 --> 0:16:09.120
<v Speaker 1>NASA if they can pull this off. Blip, a new

0:16:09.200 --> 0:16:13.120
<v Speaker 1>drone for the Navy that is a pilot less aircraft,

0:16:13.160 --> 0:16:16.200
<v Speaker 1>took its first flight this week. This one's unique because

0:16:16.240 --> 0:16:19.680
<v Speaker 1>it's stealthy, and it also should be able to replace

0:16:19.800 --> 0:16:23.080
<v Speaker 1>manned fighters, and if things work out as planned, it

0:16:23.080 --> 0:16:25.760
<v Speaker 1>will be able to take off and land on aircraft carriers,

0:16:25.760 --> 0:16:28.840
<v Speaker 1>which would be a first. It has a longer range

0:16:28.840 --> 0:16:32.000
<v Speaker 1>than manned fighters, over two thousand miles, meaning that an

0:16:32.040 --> 0:16:35.040
<v Speaker 1>aircraft carrier could sit hundreds of miles away from the

0:16:35.120 --> 0:16:39.720
<v Speaker 1>target and launch these drones at enemy targets, particularly at

0:16:39.760 --> 0:16:42.640
<v Speaker 1>any aircraft installations where you don't want to be flying

0:16:42.680 --> 0:16:45.840
<v Speaker 1>people near them anyway. So if things work out in

0:16:45.880 --> 0:16:48.480
<v Speaker 1>the next couple of years, those things will start landing

0:16:48.520 --> 0:16:52.920
<v Speaker 1>and taking off from carriers and that will begin, you know,

0:16:52.960 --> 0:16:54.800
<v Speaker 1>that will be the start of the beginning of the

0:16:54.920 --> 0:16:59.240
<v Speaker 1>end of manned flight, probably because once you get drones

0:16:59.320 --> 0:17:02.600
<v Speaker 1>that can replay fighters, robots are going to take over

0:17:02.640 --> 0:17:07.520
<v Speaker 1>that whole business. Probably. Blip pharmacies in the United States

0:17:07.680 --> 0:17:11.360
<v Speaker 1>have a problem. People who are addicted to pain killers

0:17:11.359 --> 0:17:14.960
<v Speaker 1>have started robbing pharmacies to get the drugs in the

0:17:15.080 --> 0:17:17.560
<v Speaker 1>same way that people rob banks. You know, like a

0:17:17.600 --> 0:17:20.680
<v Speaker 1>guy with a mask or a you know, pantyhose over

0:17:20.720 --> 0:17:23.040
<v Speaker 1>his face comes in with a gun or a machete

0:17:23.119 --> 0:17:26.760
<v Speaker 1>or a knife for something like that and demands, you know,

0:17:26.800 --> 0:17:29.040
<v Speaker 1>it's not give me all your money. It's give me

0:17:29.160 --> 0:17:32.880
<v Speaker 1>your pain killers. And this is happening more and more

0:17:32.960 --> 0:17:36.000
<v Speaker 1>at local drug stores. There are now hundreds of pharmacy

0:17:36.080 --> 0:17:40.200
<v Speaker 1>robberies every year. It's getting so bad that we may

0:17:40.240 --> 0:17:43.800
<v Speaker 1>have to start buying our prescriptions through cages or through

0:17:43.880 --> 0:17:47.760
<v Speaker 1>bulletproof glass dividers to keep robbers away from the drugs.

0:17:48.119 --> 0:17:50.600
<v Speaker 1>If you go to how stuff works and read how

0:17:50.720 --> 0:17:55.560
<v Speaker 1>OxyContin works, you can understand why this is happening. Blip.

0:17:56.520 --> 0:17:59.520
<v Speaker 1>And finally I saw this this morning and it it

0:17:59.720 --> 0:18:02.719
<v Speaker 1>just well, let me say that someone suggested that I

0:18:02.960 --> 0:18:06.439
<v Speaker 1>end on something that was particularly interesting and funny to be,

0:18:06.600 --> 0:18:09.840
<v Speaker 1>so this is it. I saw an article in Fast

0:18:09.880 --> 0:18:14.240
<v Speaker 1>Company magazine talking about the death of Dig. If you've

0:18:14.280 --> 0:18:18.440
<v Speaker 1>been following social media sites, Dig started imploding last year

0:18:18.600 --> 0:18:22.280
<v Speaker 1>when they did a redesign that that absolutely ticked off

0:18:22.359 --> 0:18:26.200
<v Speaker 1>their audience. So they haven't recovered from that, and so

0:18:26.359 --> 0:18:29.760
<v Speaker 1>the article is called why dig may never find its

0:18:29.800 --> 0:18:32.560
<v Speaker 1>way back. So I was reading this article and way

0:18:32.600 --> 0:18:35.359
<v Speaker 1>down at the bottom of it, there is this amazing

0:18:35.440 --> 0:18:40.439
<v Speaker 1>little paragraph that says, and I quote, most would be

0:18:40.520 --> 0:18:44.040
<v Speaker 1>shocked to learn that some of Dig's competitors actually pay

0:18:44.119 --> 0:18:48.720
<v Speaker 1>people to generate interesting, witty and intellectual comments. It's not

0:18:48.880 --> 0:18:52.520
<v Speaker 1>discussed in many circles, but nobody really worries if it

0:18:52.560 --> 0:18:56.320
<v Speaker 1>makes us laugh, smile or think? Who cares if it's artificial?

0:18:56.600 --> 0:18:59.840
<v Speaker 1>End quote? Now is that true? Like when you go

0:18:59.880 --> 0:19:04.119
<v Speaker 1>to Reddit or slash dot or farc are you you know,

0:19:04.200 --> 0:19:07.120
<v Speaker 1>are a lot of the comments being produced by ringers

0:19:07.200 --> 0:19:09.800
<v Speaker 1>who have been paid to put those comments in there?

0:19:10.160 --> 0:19:11.960
<v Speaker 1>And if it is true, how much do you get

0:19:12.000 --> 0:19:15.680
<v Speaker 1>paid to put artificial comments into a website? Like? Think
