1 00:00:00,520 --> 00:00:03,600 Speaker 1: Welcome to brain Stuff from house stuff works dot com, 2 00:00:03,600 --> 00:00:14,920 Speaker 1: where smart happens him Marshall Brain and welcome to this 3 00:00:14,960 --> 00:00:18,400 Speaker 1: week's Friday news round up. Let's start by looking at 4 00:00:18,480 --> 00:00:22,640 Speaker 1: several extreme forms of tourism that came to light this week. 5 00:00:23,400 --> 00:00:26,920 Speaker 1: Virgin Galactic gave reporters a look at their new vehicle 6 00:00:27,040 --> 00:00:31,760 Speaker 1: for space tourism, called Spaceship Too. If you google brain 7 00:00:31,920 --> 00:00:35,080 Speaker 1: Stuff Space Tourism, you can find a video that takes 8 00:00:35,080 --> 00:00:40,440 Speaker 1: you inside this spaceship. Virgin also announced Virgin Oceanic, which 9 00:00:40,440 --> 00:00:43,000 Speaker 1: has a sub that's supposed to be able to handle 10 00:00:43,040 --> 00:00:46,519 Speaker 1: the deepest oceans on Earth for the first time. That 11 00:00:46,520 --> 00:00:50,720 Speaker 1: would be thirty seven thousand feet deep, or roughly the 12 00:00:50,800 --> 00:00:54,800 Speaker 1: height of Mount Everest underwater. It's fascinating to think about this. 13 00:00:55,360 --> 00:00:58,720 Speaker 1: Even today, with all our technology, there are parts of 14 00:00:58,760 --> 00:01:01,920 Speaker 1: the ocean that have not yet been explored by people 15 00:01:02,400 --> 00:01:05,240 Speaker 1: because we don't have a sub that can handle the depth. 16 00:01:05,720 --> 00:01:09,040 Speaker 1: And this Virgin Oceanic sub will be able to explore 17 00:01:09,080 --> 00:01:12,960 Speaker 1: the ocean in style. It's like an underwater fighter plane. 18 00:01:13,319 --> 00:01:17,160 Speaker 1: You can google brain Stuff Virgin Oceanic to see the 19 00:01:17,240 --> 00:01:20,360 Speaker 1: sub and understand what some of its missions might be. 20 00:01:21,240 --> 00:01:25,279 Speaker 1: There were also interesting articles this week on excursions into 21 00:01:25,319 --> 00:01:29,839 Speaker 1: two human exclusion zones and the amazing amount of wildlife 22 00:01:29,880 --> 00:01:33,959 Speaker 1: that's flourishing inside of them. One exclusion zone surrounds the 23 00:01:34,040 --> 00:01:37,520 Speaker 1: Chernobyl Nuclear power plant, and the other is in the 24 00:01:37,600 --> 00:01:43,560 Speaker 1: demilitarized Zone between North and South Korea. The Chernobyl exclusion 25 00:01:43,680 --> 00:01:46,160 Speaker 1: zone is easy to understand. They just made this great, 26 00:01:46,200 --> 00:01:50,080 Speaker 1: big circle around the power plant and decided to evacuate 27 00:01:50,120 --> 00:01:53,080 Speaker 1: all the people and keep them out because of the radioactivity. 28 00:01:53,440 --> 00:01:57,080 Speaker 1: The Demilitarized Zone is a strip that's two and a 29 00:01:57,160 --> 00:02:00,120 Speaker 1: half miles wide and about a hundred and sixty miles 30 00:02:00,160 --> 00:02:03,760 Speaker 1: long that's been fenced off to keep North and South 31 00:02:03,840 --> 00:02:07,520 Speaker 1: Korea from killing each other. It's amazing what nature will 32 00:02:07,560 --> 00:02:10,680 Speaker 1: do once people are eliminated from a piece of land 33 00:02:10,760 --> 00:02:14,480 Speaker 1: like this. A new human exclusion zone has been created 34 00:02:14,520 --> 00:02:19,280 Speaker 1: around Japan's stricken nuclear power plant that basically melted down 35 00:02:19,360 --> 00:02:24,480 Speaker 1: after the earthquake. A thirty kilometer evacuation area is now 36 00:02:24,680 --> 00:02:28,720 Speaker 1: virtually devoid of all people. A reporter went in this 37 00:02:28,800 --> 00:02:31,519 Speaker 1: week with a camera to record the state of things, 38 00:02:31,639 --> 00:02:35,160 Speaker 1: and some of it looks absolutely post apocalyptic, like a 39 00:02:35,200 --> 00:02:39,359 Speaker 1: waste land. Parts of it were leveled completely by the tsunami, 40 00:02:39,639 --> 00:02:43,000 Speaker 1: and then human beings were sucked out, and then radioactive 41 00:02:43,000 --> 00:02:46,080 Speaker 1: waste from the reactors melt down ended up settling on 42 00:02:46,160 --> 00:02:49,040 Speaker 1: the land, and all that's left now is the occasional 43 00:02:49,200 --> 00:02:53,000 Speaker 1: stray dog or cow roaming free. Given the levels of 44 00:02:53,080 --> 00:02:56,360 Speaker 1: radiation that he observed and documented, it's really hard to 45 00:02:56,400 --> 00:02:59,640 Speaker 1: say what will happen to these hundreds of square kilometers 46 00:02:59,680 --> 00:03:02,680 Speaker 1: of and in Japan going forward. If you check the 47 00:03:02,680 --> 00:03:05,680 Speaker 1: brain Stuff blog, you can find the video that he took. 48 00:03:06,000 --> 00:03:10,000 Speaker 1: There were also several technological fiascos reported this week, and 49 00:03:10,040 --> 00:03:13,320 Speaker 1: two of the more interesting involved the Nintendo three DS 50 00:03:13,480 --> 00:03:17,120 Speaker 1: and the Motorola Zoom tablet. With the Zoom, the pre 51 00:03:17,240 --> 00:03:20,080 Speaker 1: release hype was intense and it was built as the 52 00:03:20,160 --> 00:03:24,040 Speaker 1: tablet to take on the iPad too. Unfortunately, it's not 53 00:03:24,200 --> 00:03:27,640 Speaker 1: lived up to those expectations, selling only about a hundred 54 00:03:27,639 --> 00:03:31,560 Speaker 1: thousand copies since the launch. What's holding it back The 55 00:03:31,680 --> 00:03:34,560 Speaker 1: prices a problem. It's more expensive than the iPad too, 56 00:03:34,800 --> 00:03:37,000 Speaker 1: so as the lack of familiarity on the part of 57 00:03:37,000 --> 00:03:39,800 Speaker 1: the buying public. It's also invisible if you try to 58 00:03:39,840 --> 00:03:42,480 Speaker 1: find it in a place like Best Buy. Add to 59 00:03:42,560 --> 00:03:44,760 Speaker 1: that the fact that it came out at the same 60 00:03:44,800 --> 00:03:47,560 Speaker 1: time as the iPad too, and the iPad to just 61 00:03:47,920 --> 00:03:52,720 Speaker 1: essentially completely overshadowed it in the marketplace. So it's starting 62 00:03:52,720 --> 00:03:55,240 Speaker 1: point hasn't gone really well, and it's hard to say 63 00:03:55,280 --> 00:03:58,120 Speaker 1: what will happen to it going forward. On the three 64 00:03:58,200 --> 00:04:01,840 Speaker 1: DS side, there are are a surprising number of complaints 65 00:04:01,840 --> 00:04:05,840 Speaker 1: about the three D screen. As you'll recall, this screen 66 00:04:05,920 --> 00:04:09,680 Speaker 1: does not require three D glasses. Instead, lens is built 67 00:04:09,720 --> 00:04:12,560 Speaker 1: into the screen direct two different images into your left 68 00:04:12,600 --> 00:04:15,360 Speaker 1: and right eyes. To get the full three D effect, 69 00:04:15,360 --> 00:04:17,440 Speaker 1: you need to be centered on the screen, and the 70 00:04:17,480 --> 00:04:21,200 Speaker 1: screen needs to be the correct distance from your eyes. Apparently, 71 00:04:21,600 --> 00:04:25,200 Speaker 1: the new screen causes a bad experience for some people. 72 00:04:25,600 --> 00:04:28,159 Speaker 1: They get dizzy, or they get headaches, or you know, 73 00:04:28,320 --> 00:04:30,400 Speaker 1: it just doesn't feel right to them as they look 74 00:04:30,440 --> 00:04:34,040 Speaker 1: at it. And Nintendo is suggesting using the three D 75 00:04:34,120 --> 00:04:37,280 Speaker 1: feature for only thirty minutes at a time and not 76 00:04:37,400 --> 00:04:40,359 Speaker 1: letting kids under seven use it at all. The whole 77 00:04:40,400 --> 00:04:43,680 Speaker 1: thing has been a little uncomfortable for the launch of 78 00:04:43,720 --> 00:04:47,039 Speaker 1: this amazing new device. If you google Interesting Reading number 79 00:04:47,120 --> 00:04:49,960 Speaker 1: seven twenty and seven twenty two, you can get details 80 00:04:49,960 --> 00:04:54,000 Speaker 1: on these two situations we've all heard of riddling It's 81 00:04:54,000 --> 00:04:56,560 Speaker 1: a drug that's supposed to help kids suffering from a 82 00:04:56,680 --> 00:05:01,040 Speaker 1: d D or a d h D, essentially attention deficit disorder. 83 00:05:01,640 --> 00:05:04,760 Speaker 1: Lots of college students also use it, however, because they 84 00:05:04,800 --> 00:05:07,840 Speaker 1: think it improves their concentration one studying as well as 85 00:05:07,880 --> 00:05:12,880 Speaker 1: improving retention. Now scientists are studying why riddle in might help. 86 00:05:13,160 --> 00:05:15,159 Speaker 1: It turns out that it really does help. If you 87 00:05:15,279 --> 00:05:19,000 Speaker 1: give riddle into rats, they learn things faster. It appears 88 00:05:19,040 --> 00:05:22,279 Speaker 1: to do this by increasing two different kinds of dopamine. 89 00:05:22,640 --> 00:05:25,800 Speaker 1: One type of dopamine affects the speed of learning and 90 00:05:25,839 --> 00:05:30,240 Speaker 1: the other type effects focus. Right now, using riddle in 91 00:05:30,240 --> 00:05:33,480 Speaker 1: in this way is ill advised because it's a prescription drug. 92 00:05:33,760 --> 00:05:36,440 Speaker 1: But in the future the drug might be relabeled as 93 00:05:36,440 --> 00:05:39,839 Speaker 1: a brain boosting drug, so it becomes much more widely available. 94 00:05:40,160 --> 00:05:43,160 Speaker 1: If you google interesting Reading seven twenty one, you can 95 00:05:43,200 --> 00:05:47,239 Speaker 1: get details on using riddle in in this way. Remember 96 00:05:47,240 --> 00:05:49,800 Speaker 1: a couple of weeks ago we talked about a streaming 97 00:05:49,880 --> 00:05:54,480 Speaker 1: DVD service called z Diva. They set up physical DVD 98 00:05:54,680 --> 00:05:59,040 Speaker 1: players playing physical DVDs, and then they routed the video 99 00:05:59,120 --> 00:06:02,360 Speaker 1: signals from these DVD players over the Internet to create 100 00:06:02,400 --> 00:06:06,400 Speaker 1: a streaming service. The goal is to get around Hollywood's 101 00:06:06,400 --> 00:06:09,760 Speaker 1: restrictions on movie streaming, and the Diva claim that their 102 00:06:09,800 --> 00:06:13,000 Speaker 1: service is the same as a video rental store because 103 00:06:13,040 --> 00:06:17,560 Speaker 1: they're using physical DVDs and physical DVD players and they're 104 00:06:17,600 --> 00:06:21,000 Speaker 1: only allowing one person to watch each DVD at a time. 105 00:06:21,680 --> 00:06:24,640 Speaker 1: This week, Za Diva got sued by six of the 106 00:06:24,680 --> 00:06:28,160 Speaker 1: biggest studios in Hollywood, which is pretty amazing. Since the 107 00:06:28,279 --> 00:06:32,080 Speaker 1: Diva launched in March and has only five employees, it'll 108 00:06:32,120 --> 00:06:34,240 Speaker 1: be interesting to see how this shakes out. If you 109 00:06:34,320 --> 00:06:37,040 Speaker 1: google Interesting Reading number seven twenty one, you can get 110 00:06:37,040 --> 00:06:41,680 Speaker 1: the details. There's a fascinating article this week that discusses 111 00:06:41,839 --> 00:06:47,200 Speaker 1: seven common things that people do wrong. Take, for example, showering. Now, 112 00:06:47,200 --> 00:06:49,839 Speaker 1: this seems like something that's really simple and hard to 113 00:06:49,880 --> 00:06:53,159 Speaker 1: screw up, but it appears that we really are doing 114 00:06:53,200 --> 00:06:56,280 Speaker 1: this wrong. Many of us take showers daily or even 115 00:06:56,360 --> 00:06:59,680 Speaker 1: twice daily, with hot water, soap, and maybe even a 116 00:07:00,040 --> 00:07:03,080 Speaker 1: bonge or a washcloth or a loofer or something to 117 00:07:03,160 --> 00:07:07,400 Speaker 1: get the pores really clean. The problem is that showering 118 00:07:07,480 --> 00:07:12,160 Speaker 1: like this damages the skin, so the article recommends fewer showers, 119 00:07:12,280 --> 00:07:16,560 Speaker 1: cooler water, and safer soap without the abrasion, and we're 120 00:07:16,560 --> 00:07:20,520 Speaker 1: supposed to avoid a towel and air dry ourselves instead 121 00:07:20,720 --> 00:07:23,800 Speaker 1: to minimize the effect on our skin. Now, if you 122 00:07:23,840 --> 00:07:27,120 Speaker 1: like that idea, you'll enjoy the articles other entries on 123 00:07:27,240 --> 00:07:31,040 Speaker 1: things like pooping we're supposed to use a squatting action 124 00:07:31,160 --> 00:07:37,240 Speaker 1: rather than using a toilet, breathing, sleeping, toothbrushing, childbirthing, which 125 00:07:37,280 --> 00:07:39,679 Speaker 1: fortunately half of us don't really have to think about. 126 00:07:40,000 --> 00:07:44,480 Speaker 1: And finally, sitting, What you're supposed to do about sitting 127 00:07:44,840 --> 00:07:49,240 Speaker 1: is not sit basically, that's one recommendation. Anyway, you're supposed 128 00:07:49,280 --> 00:07:52,360 Speaker 1: to get a standing desk or an exercise desk so 129 00:07:52,400 --> 00:07:56,200 Speaker 1: that you can avoid the whole sedentary sitting thing. Another 130 00:07:56,720 --> 00:07:59,240 Speaker 1: is a seat that lets you recline at a hundred 131 00:07:59,320 --> 00:08:02,880 Speaker 1: and thirty five degree angle. If you google Interesting Reading 132 00:08:02,960 --> 00:08:05,960 Speaker 1: number seven twenty, you can find this article. It really 133 00:08:06,040 --> 00:08:09,800 Speaker 1: is pretty amusing to read it. Lots of people are 134 00:08:09,880 --> 00:08:13,920 Speaker 1: unemployed right now, so where are the decent paying jobs. 135 00:08:14,400 --> 00:08:17,000 Speaker 1: It has been well known for some time that jobs 136 00:08:17,000 --> 00:08:19,600 Speaker 1: in the medical field have openings and they tend to 137 00:08:19,640 --> 00:08:23,040 Speaker 1: pay well. I also did an article on the BAJA 138 00:08:23,280 --> 00:08:26,400 Speaker 1: s A program this week. S a A stands for 139 00:08:26,440 --> 00:08:30,280 Speaker 1: the Society of Automotive Engineers and Baja SEE is a 140 00:08:30,360 --> 00:08:35,160 Speaker 1: college student program where college students build little ten horsepower 141 00:08:35,240 --> 00:08:39,000 Speaker 1: Baja style cars and race them. One of the videos 142 00:08:39,040 --> 00:08:44,040 Speaker 1: in that article suggests that mechanical engineers and manufacturing engineers 143 00:08:44,040 --> 00:08:46,960 Speaker 1: are in demand right now. If you google brain stuff 144 00:08:47,080 --> 00:08:50,040 Speaker 1: Baja s a E. You can see the details and 145 00:08:50,080 --> 00:08:53,280 Speaker 1: watch that video. And then there was a piece in 146 00:08:53,280 --> 00:08:59,000 Speaker 1: Interesting Reading seven twenty entitled fifteen overlooked and underappreciated blue 147 00:08:59,040 --> 00:09:03,040 Speaker 1: collar jobs pay well. This is pretty interesting because the 148 00:09:03,160 --> 00:09:07,920 Speaker 1: jobs are esoteric. At number one is and if you 149 00:09:07,920 --> 00:09:10,920 Speaker 1: think about this, what you know what could be the 150 00:09:11,000 --> 00:09:15,280 Speaker 1: number one most overlooked under appreciated blue collar job in America? 151 00:09:15,520 --> 00:09:20,200 Speaker 1: It's elevator installers and repairers, with an average salary of 152 00:09:20,280 --> 00:09:23,520 Speaker 1: sixty nine thousand dollars a year. That would at least 153 00:09:23,559 --> 00:09:26,360 Speaker 1: be a job that's indoor. Some of these jobs are not, 154 00:09:26,559 --> 00:09:29,160 Speaker 1: and that might make them less desirable to some people. 155 00:09:29,800 --> 00:09:33,439 Speaker 1: The best paying job on the list is mining engineer 156 00:09:33,559 --> 00:09:37,360 Speaker 1: at seventy nine thousand dollars per year. Number twelve is 157 00:09:37,400 --> 00:09:40,960 Speaker 1: commercial divers at fifty eight thousand dollars per year, and 158 00:09:41,040 --> 00:09:44,920 Speaker 1: so on. Google Interesting Reading number seven twenty for details 159 00:09:45,000 --> 00:09:49,560 Speaker 1: on these jobs.

Supposedly, all you have 165 00:10:05,760 --> 00:10:09,480 Speaker 1: to do is hold the closed door button down and 166 00:10:09,640 --> 00:10:13,080 Speaker 1: keep it down while you press your floor number, and 167 00:10:13,120 --> 00:10:16,240 Speaker 1: then as the elevator starts moving, you can release those 168 00:10:16,280 --> 00:10:18,920 Speaker 1: two buttons. It can't hurt to try it next time 169 00:10:18,960 --> 00:10:21,760 Speaker 1: you're on an elevator. If you google interesting Reading number 170 00:10:21,800 --> 00:10:25,720 Speaker 1: seven nineteen, you can get instructions for this hat. In 171 00:10:25,800 --> 00:10:30,640 Speaker 1: the past, cows obviously have produced cow's milk, but now 172 00:10:30,840 --> 00:10:33,920 Speaker 1: some cows, about three hundred of them, are producing human 173 00:10:34,000 --> 00:10:38,720 Speaker 1: milk thanks to genetic engineering, and thanks to relax genetic 174 00:10:38,760 --> 00:10:43,080 Speaker 1: engineering regulations that are in place in China, scientists have 175 00:10:43,240 --> 00:10:48,440 Speaker 1: inserted human genes into cows to make this possible. The 176 00:10:48,520 --> 00:10:51,880 Speaker 1: ultimate goal is to create milk from cows that's nearly 177 00:10:51,920 --> 00:10:55,040 Speaker 1: identical to human milk as a way to improve the 178 00:10:55,120 --> 00:10:57,960 Speaker 1: milk for infants that are bottle fed. One of the 179 00:10:58,040 --> 00:11:01,760 Speaker 1: key differences in human milk is a protein called lyso zyme, 180 00:11:01,840 --> 00:11:06,120 Speaker 1: which can kill bacteria. Other human proteins help boost a 181 00:11:06,160 --> 00:11:09,960 Speaker 1: baby's immune system. It's not yet a perfect duplicate of 182 00:11:10,000 --> 00:11:13,040 Speaker 1: human milk, but it's much closer than straight cow's milk 183 00:11:13,080 --> 00:11:17,040 Speaker 1: would be. Google interesting reading number seven nineteen for details. 184 00:11:17,880 --> 00:11:21,640 Speaker 1: How much data can your cell phone or smartphone collect 185 00:11:21,679 --> 00:11:24,840 Speaker 1: about you? Quite a bit, it turns out, as discovered 186 00:11:24,880 --> 00:11:29,079 Speaker 1: by a European politician who requested his records to find 187 00:11:29,120 --> 00:11:32,960 Speaker 1: out what the cell phone company was keeping about him. Apparently, 188 00:11:33,080 --> 00:11:37,200 Speaker 1: his cell phone company logged his GPS information tens of 189 00:11:37,280 --> 00:11:39,760 Speaker 1: thousands of times over the course of a year or so, 190 00:11:40,160 --> 00:11:44,679 Speaker 1: along with his call history. A newspaper then cross correlated 191 00:11:44,800 --> 00:11:48,080 Speaker 1: that data stream with his Twitter feed and other publicly 192 00:11:48,120 --> 00:11:52,800 Speaker 1: available information to basically map out his life. It's kind 193 00:11:52,840 --> 00:11:55,480 Speaker 1: of shocking, really. There's a little tool you can run 194 00:11:55,840 --> 00:11:58,280 Speaker 1: in the article where you can see on a map 195 00:11:58,440 --> 00:12:02,280 Speaker 1: exactly where he's going and what's happening in his life 196 00:12:02,320 --> 00:12:05,400 Speaker 1: at those different moments as they go by, and it 197 00:12:05,520 --> 00:12:08,720 Speaker 1: shows that we are completely unanonymous if we have a 198 00:12:08,760 --> 00:12:11,160 Speaker 1: phone in our pocket, whether we like it or not. 199 00:12:11,280 --> 00:12:13,679 Speaker 1: This kind of data keeping will be happening more and 200 00:12:13,720 --> 00:12:16,959 Speaker 1: more in the future. If you google interesting Reading number 201 00:12:16,960 --> 00:12:20,040 Speaker 1: seven nineteen you can see how much information can be 202 00:12:20,080 --> 00:12:24,559 Speaker 1: gathered from a smartphone. And finally, there are several news 203 00:12:24,600 --> 00:12:28,240 Speaker 1: items this week on stem cells. One involved an effort 204 00:12:28,280 --> 00:12:31,360 Speaker 1: to grow a human eye from stem cells. Another is 205 00:12:31,400 --> 00:12:34,959 Speaker 1: an attempt to grow a full human heart from stem cells. 206 00:12:35,480 --> 00:12:38,560 Speaker 1: The idea of growing replacement hearts for people is getting 207 00:12:38,600 --> 00:12:41,079 Speaker 1: closer to reality, and if you can grow a heart, 208 00:12:41,400 --> 00:12:44,360 Speaker 1: then it's probably likely you can also grow other organs 209 00:12:44,400 --> 00:12:47,920 Speaker 1: like kidneys or livers or stomachs for that matter as well. 210 00:12:48,520 --> 00:12:51,800 Speaker 1: The heart technique involves starting with a donor heart and 211 00:12:51,880 --> 00:12:56,640 Speaker 1: washing away everything but the kellagians scaffolding to give the 212 00:12:56,679 --> 00:13:00,880 Speaker 1: new hearted shape. Then that skeleton or the saffolding is 213 00:13:00,960 --> 00:13:03,920 Speaker 1: seated with stem cells from the person who will receive 214 00:13:03,960 --> 00:13:07,480 Speaker 1: the heart, which then grow to create a new heart 215 00:13:07,640 --> 00:13:11,760 Speaker 1: on that scaffolding. One problem during the growth process is 216 00:13:11,760 --> 00:13:15,400 Speaker 1: a blood supply. As the cells thicken, they need blood 217 00:13:15,440 --> 00:13:18,120 Speaker 1: to get oxygen and nutrients, so there really needs to 218 00:13:18,120 --> 00:13:21,440 Speaker 1: be a circulation system that can handle the delivery of 219 00:13:21,480 --> 00:13:24,840 Speaker 1: that blood. And another problem is the nerve cells to 220 00:13:24,880 --> 00:13:28,040 Speaker 1: control beating, which are fairly complex in a natural heart. 221 00:13:28,400 --> 00:13:32,080 Speaker 1: But if these hurdles can be overcome, then replacement hearts 222 00:13:32,120 --> 00:13:36,679 Speaker 1: could become a reality.
