An anonymous reader writes "Researchers at the Scripps Research Institute are potentially one step closer to creating life. In an experiment they recently created enzymes that can replicate and evolve. 'It kind of blew me away,' said team member Tracey Lincoln of the Scripps Research Institute, who is working on her Ph.D. 'What we have is non-living, but we've been able to show that it has some life-like properties, and that was extremely interesting.'"

An anonymous reader writes "A recent study suggests the downfall of individual researchers, who are being rapidly replaced by enormous research groups. Quoting: '... in recent decades — especially since the Soviet success in launching the Sputnik satellite in 1957 — the trend has been to create massive institutions that foster more collaboration and garner big chunks of funding. And it is harder now to achieve scientific greatness. A study of Nobel Prize winners in 2005 found that the accumulation of knowledge over time has forced great minds to toil longer before they can make breakthroughs. The age at which thinkers produce significant innovations increased about six years during the 20th century.'"

Khemisty writes "Earth may be trapped in an abnormal bubble of space-time that is particularly void of matter. Scientists say this condition could account for the apparent acceleration of the universe's expansion, for which dark energy currently is the leading explanation. Until now, there has been no good way to choose between dark energy or the void explanation, but a new study outlines a potential test of the bubble scenario. If we were in an unusually sparse area of the universe, then things could look farther away than they really are and there would be no need to rely on dark energy as an explanation for certain astronomical observations. 'If we lived in a very large under-density, then the space-time itself wouldn't be accelerating,' said researcher Timothy Clifton of Oxford University in England. 'It would just be that the observations, if interpreted in the usual way, would look like they were.'"

Kligat writes "For the first time since 2003, the International Space Station has utilized the rockets on the European Space Agency's Automated Transfer Vehicle to dodge leftover remnants of a defunct satellite. The Russian Cosmos-2421 was launched in June 2006 to track Western Navy vessels and is believed by NASA to have exploded — 'likely due to a self-destruct command issued by Russian officials' according to the article — leaving 500 pieces of space debris. Ordinarily, the rockets on the ATV are used to take the ISS away from Earth's atmosphere and reduce drag. In this case, the 5-minute firing caused the ISS to move downward because it was already near the top of its acceptable range. Estimated probability of impact was 1 in 72, and an avoidance maneuver is called for if the probability is greater than 1 in 10,000. The space junk was predicted to pass the ISS within just a mile."

Hugh Pickens writes "For a long time, humans were pretty dumb, doing little but make 'the same very boring stone tools for almost 2 million years,' says Philipp Khaitovich of the Partner Institute for Computational Biology in Shanghai. Then, 150,000 years ago, our big brains suddenly got smart. We started innovating. We tried different materials. We started creating art and maybe even religion. To understand what caused the cognitive spurt, researchers examined chemical brain processes known to have changed in the past 200,000 years. Comparing apes and humans, they found the most robust differences were for processes involved in energy metabolism. The finding suggests that increased access to calories spurred our cognitive advances, although definitive claims of causation are premature. In most animals, the gut needs a lot of energy to grind out nourishment from food sources. But cooking, by breaking down fibers and making nutrients more readily available, is a way of processing food outside the body. Eating (mostly) cooked meals would have lessened the energy needs of our digestion systems, thereby freeing up calories for our brains. Today, humans have relatively small digestive systems and allocate around 20% of their total energy to the brain, compared to approximately 13% for non-human primates and 2-8% for other vertebrates. While other theories for the brain's cognitive spurt have not been ruled out, the finding sheds light on what made us, as Khaitovich put it, 'so strange compared to other animals.'"

TaeKwonDood writes "Carl Wieman is the 2001 Nobel Prize winner in Physics but what he cares most about is fixing science education. The real issue is, can someone who went through 20 years of science education as a student, lived his life in academia since then and even got a Nobel prize get a fair shake from bureaucrats who like education the way it is — flawed and therefore always needing more money?"

VindictivePantz writes to mention that scientists have discovered some bizarre properties of glass and are already applying that knowledge to create what is being called "metallic glass." "The breakthrough involved solving the decades-old problem of just what glass is. It has been known that that despite its solid appearance, glass and gels are actually in a 'jammed' state of matter — somewhere between liquid and solid — that moves very slowly. Like cars in a traffic jam, atoms in a glass are in something like suspended animation, unable to reach their destination because the route is blocked by their neighbors. So even though glass is a hard substance, it never quite becomes a proper solid, according to chemists and materials scientists."

wifeoflurker writes "Can someone give me recommendations for a desk chair to give my husband as a Father's Day gift? He currently uses a cheap one he got from Office Max, but I want him to have a really comfortable one. He spends his life in this chair (coding and lurking on Slashdot). I don't have time to research good chairs on the internet today (I'm chasing my 10 month old around, and she seems to get into the most mischief when I'm staring at the computer screen), so I figured a few folks here might share their personal recommendations." Has there been any great progress in the state of the art (of sitting) since the last time readers sought recommendations for back-friendly chairs a few years back, or the perfect computer chair nearly a decade back? Is there even such a thing as a back-friendly chair, or should we all be in astronaut-style lounge workstations?

Ant contributes a link spotted on Neatorama that may upset middle school Earth Science teachers, writing "LiveScience says Earth's simple schematic is not core, mantle, and crust anymore. It is more like the gooey center of a chocolate morsel harboring peanut butter and honey. Inner Earth is far more nuanced than outward appearances would suggest. A new model is proposed in the May 2, 2008, issue of the journal Science."

Ant writes in to note a study indicating that, because of air pollution, the smell of flowers is not wafting as far as it once did. Pollutants from power plants and automobiles destroy flowers' aromas, the study suggests: "The scent molecules produced by flowers in a less polluted environment, such as in the 1800s, could travel for roughly 1,000 to 1,200 meters; but in today's polluted environment downwind of major cities, they may travel only 200 to 300 meters." The finding could help explain why some pollinators, particularly bees, are declining in certain parts of the world.

seattle-pk writes "Males are apparently clueless when it comes to interpreting sexual intent from females, according to a recent study (PDF) from Indiana University's Department of Psychological and Brain Sciences. Men were found commonly to perceive more sexual intent in women's behavior than women were intending to convey. (A campus survey showed that 68% of college females had an experience where a male mistook signs of friendliness for affection.) However, the study also shows that men were quite likely to misperceive sexual interest as friendliness. 'Rather than seeing the world through sex-colored glasses, men seemed just to have blurry vision of sorts, overall,' according to the article. If you're a male who ever mistook the meaning of a barista's smile, looks like you're not alone."

Pickens writes "Mankind has always had a fascination with monsters, and mythologies from around the world include stories of strange and terrifying creatures. Examples include the half-bull, half-human Minotaur of Greek myths, the living clay Golem of Jewish traditions, British elves and Chinese dragons. Live Science has an interesting photo essay on their ten favorite monsters that may have a basis in real life. Their rogue's gallery includes the Ogopogo, a mysterious monster in Canada's Lake Okanagan; the Chupacabra, that Latin Americans believe is the unholy result of secret US government experiments in the jungles of Puerto Rico; and the perennial favorite Bigfoot."

Regular Slashdot contributor Bennett Haselton has some opinions on child safety online and the use of fear mongering. Here are his thoughts. "The National Center for Missing and Exploited Children has been running online ads for several years saying that "Each year 1 in 5 children is sexually solicited online", a statistic that has been endlessly repeated, including by vendors of blocking software and by politicians who often paraphrase it to say that 1 in 5 children "are approached by online predators". While others have quietly documented the problems with this statistic, lawmakers still bring it out every year in a push for more online regulation (preempted this year only by the topic du jour of cyberbullying), so it's time for anti-censorship organizations to start campaigning more aggressively against the misleading "1 in 5" number. That means two things: framing the debate with more accurate numbers, and holding the parties accountable for disseminating the wrong ones -- and that means naming names, including those of organizations like the NCMEC that are normally beyond reproach." Read below for the rest. I have no doubt that on balance, the world is a better place because of the NCMEC and what they've done, and God knows how I'd feel about them if they'd helped me find a lost child. But the good things they've done shouldn't be viewed as political capital that they can withdraw against in order to be above criticism for spreading the "1 in 5" meme. The longer they go on implying to parents that there is a 1-in-5 chance their kid will be asked by an adult to meet in person for sex, the more I think it tarnishes their whole legacy. (The NCMEC did not respond to contact requests for this article.)

First, what the 1-in-5 number actually means. It originated with a study done in 2000 by the Crimes Against Children Research Center at the University of New Hampshire, which surveyed 1,501 Internet-using youth age 10 through 17. The actual relevant findings of the study were as follows:

• The 1 in 5 figure was the number that had received at least one instance of unwanted sex talk (including from other teenagers), or sex talk from an adult (whether wanted or not), in the past year.

• The proportion of respondents who received a sexual flirtation from an adult, followed by a request to talk on the phone or meet in person, was about 1%.

• The number of survey respondents who actually befriended an adult online and then met the adult in person for sexual purposes, was zero.

Specifically: About 19% of respondents said had received a "sexual solicitation or approach" (my emphasis), and "sexual solicitations and approaches" were defined as: "requests to engage in sexual activities or sexual talk or give personal sexual information that were unwanted or, whether wanted or not, made by an adult". That means any unwanted sex talk, including from other teens, even if limited to one occurrence in the entire previous year, would cause a respondent to be included in the 19% figure (which, when you define it that broadly, actually sounds pretty low). To say that those 1 in 5 minors were "sexually solicited" -- literally, asked for sex -- is simply false.

The actual proportion of respondents who reported that someone made sexual overtures and asked to talk on the phone or meet in person -- what the study called an "aggressive sexual solicitation" -- was 3%, and 34% of those requests were known to have been made by adults. And even this overestimates the proportion of minors who were truly "sexually solicited", because all it means is that an adult started out by talking to them sexually, and then made some request for offline contact, which could have merely been asking for a phone number. So the scenario that comes to mind when hearing that "1 in 5 children is sexually solicited online" -- of being approached sexually by an adult and asked for an in-person meeting -- had actually happened to no more than 1% of respondents, and probably much fewer than that.

And this is just considering the percentage of youth who received solicitations, not taking into account how they responded. Out of 1,501 youth surveyed, none of them reported actually meeting an adult in person for anything that they described as sexual contact. Two teens in the study had "close friendships" with adults that the authors wrote "may have had sexual aspects". One 17-year-old boy had a relationship with a woman in her late twenties that he described as "romantic" but not sexual, and they never met in person. Another 16-year-old girl became close to a man in his thirties, and they met in a public place, but she described the relationship as non-sexual, and she declined to spend the night with him. (While these could still be considered "close calls", it's worth noting that even if the 16- and 17-year-olds had actually had a sexual relationship with their adult friends, that would have in fact been legal in many U.S. states, and in any case it's not what most people think of when they hear about "children" being "sexually solicited online".)

Of course all of this depends on the accuracy of the answers that the youth gave to the surveyors. But the "1 in 5" figure was based on the youths' stated responses as well. People who cite the study can't have their cake and eat it too, taking the "1 in 5" number as accurate but discounting the fact that none of the teens surveyed reported a sexual relationship with an adult they met online.

These were the data that were available in 2000, when the "1 in 5" number started being spread. The authors of the original study followed up with a 2005 report, "Online Victimization of Youth: Five Years Later", in which the corresponding statistics were:

• 1 in 7 respondents received unwanted sex talk or sex talk from an adult, at some point in the past year.

• The proportion of respondents who received a sexual flirtation from an adult, followed by a request to communicate offline, was again about 1-2%. (4% of respondents reported a sexual flirtation plus a request to correspond offline. The new study reported that 39% of all sexual solicitations were made by adults, but did not say what proportion of "aggressive sexual solicitations" -- which included requests for offline contact -- were made by adults.)

• Out of 1,501 respondents surveyed in 2005, two did report an in-person meeting that led to a sexual crime -- one was a 15-year-old girl who met a 30-year-old man in person and had consensual sex with him, and another was a 16-year-old girl who went to a party with an older male she met online who later tried to rape her. But even these incidents (which were both reported to law enforcement) do not mean that the Internet is a more dangerous environment for youth with regard to interaction with adults. The National Center for Missing and Exploited Children's own Web site links to a study -- also by one of the authors of the "Online Victimization" report -- which found that when all types of abuse are counted, 20% of females experience some type of sexual victimization before adulthood, compared to 2 out of 750 female survey respondents in the "Online Victimization" study who reported sexual abuse by someone they met online.

The NCMEC has updated their Web site to say that "one in seven youths (10 to 17 years) experience a sexual solicitation or approach while online", although the banner ads still say 1 in 5. But I think the 1-in-7 versus 1-in-5 is hardly worth nit-picking, when the real problem is that the statement "1 in 5 children is sexually solicited online" is written in a way that virtually guarantees it will be mis-heard and passed along as a statement involving "online predators" or "pedophiles". "Authorities Say 1 in 5 Children Has Been Approached By Online Predators" reads the sub-heading of a story on ABC news. "20% of children who use computer chat rooms have been approached over the Internet by a pedophile" says an online safety site sponsored by the Albemarle County government in Virginia. "One in five kids in America are approached by online predators" says a Congressman's press release.

The NCMEC itself never says that 1 in 5 or 1 in 7 children is "approached by a pedophile", merely that they are "sexually solicited online". I still think this is false because that is not the proportion of minors who are literally solicited for sex, but suppose that you expanded "sexual solicitation" to include all sex talk, so that the statement was "technically true". That still misses the point, because the issue shouldn't be seen as a game where sides try to make their statements as alarmist as possible while still being "technically true", like the kid with his petition to ban "dihydrogen monoxide". If you say something that is virtually guaranteed to get passed along as a wrong and alarmist statement about "pedophiles", aren't you at least partly responsible?

Why, then, does the NCMEC do it? Their site does have a "Donate" link, but it's very low-key, and the site generally seems to steer first-time visitors towards actions that they can take with regard to their own children. So I'm not cynical enough to think the "1 in 5" statistic is a campaign to scare up donations; I think they really do believe they are doing good by getting people to believe that number and to take action based on it. The problem is that there is such a thing as too much worrying and too much overprotection. Sites like Facebook are often used to organize parties and events and send out venue changes, just because that's the most efficient way to do it, and if your parents ban you from getting on Facebook, you'll miss out on simple things like that. What good does that do for anybody? Critics of overprotection often say that overly sheltered kids may rebel later on and get themselves in worse trouble, and that's often true, but so what even if they don't? Your quality of life is still worse off if you're the only one in your peer group who can't get updates about your friends' parties. And your parents' quality of life will be worse if they're constantly wringing their hands thinking that there is a 1 in 5 chance their kid will be propositioned online by a pedophile.

So I would urge the NCMEC to reconsider what they're telling people. Regarding the "1 in 5" meme that's already out there, it's spread so far that it's probably too late for the NCMEC to put the genie back into the bottle. But any anti-censorship group participating in a debate about online safety should put the real statistics forward, and since many in the audience will have heard the "1 in 5" figure somewhere, take a minute to knock it down as well. You don't have to commit political suicide by calling out the NCMEC specifically for spreading the "1 in 5" number, but put the right numbers out there.

Unfortunately the subject of child safety is such that wrong information, from any source, is unlikely to be criticized if it's erring on the side of caution, but some memes die faster than others. Microsoft's resource page about "online predators" says that "if you find pornography on the family computer" -- not child porn, but regular pornography -- that could be a warning sign that "your child is the target of an online predator". I think that's a wildly irresponsible thing to be telling parents, but fortunately the meme does not seem to have spread beyond that one page, which probably not one parent in a thousand will ever actually read.

One of the best things about being a scientist is that people will pay you to research strange things, like why monkeys yell during sex. It turns out the male monkeys like loud females and will have a more "vigorous" session with them. "Counting monkey pelvic thrusts is admittedly "quite weird, but it's science," researcher Dana Pfefferle, a behavioral scientist and primatologist at the German Primate Center, told LiveScience. "You get used to it.""

Ponca City, We Love You writes "Does time slow down when you are in a traffic accident or other life threatening crisis like Neo dodging bullets in slow-motion in The Matrix? To find out, researchers developed a perceptual chronometer where numbers flickered on the screen of a watch-like unit. The scientists adjusted the speed at which the numbers flickered until it was too fast for the subjects to see. Then subjects were put in a Suspended Catch Air Device, a controlled free-fall system in which 'divers' are dropped backwards off a platform 150 feet up and land safely in a net. Subjects were asked to read the numbers on the perceptual chronometer as they fell [video]. The bottom line: While subjects could read numbers presented at normal speeds during the free-fall, they could not read them at faster-than-normal speeds. 'We discovered that people are not like Neo in The Matrix,' Eagleman said. 'The answer to the paradox is that time estimation and memory are intertwined: the volunteers merely thought the fall took a longer time in retrospect'."

wile_e_wonka writes to tell us Researchers at Harvard and the Montreal-based McGill University are working on a drug that would allow psychiatrists to dampen painful memories in their patients when combined with therapy. "They treated 19 accident or rape victims for ten days, during which the patients were asked to describe their memories of the traumatic event that had happened 10 years earlier. Some patients were given the drug, which is also used to treat amnesia, while others were given a placebo. A week later, they found that patients given the drug showed fewer signs of stress when recalling their trauma."

Ant writes "A LiveScience story discusses the cultural differences in interpreting facial expressions. The article notes that where you come from plays a large role in what part of the human face you use to determine another person's mood. That also includes communicating online with the usages of smiley faces. 'For instance, in Japan, people tend to look to the eyes for emotional cues, whereas Americans tend to look to the mouth, says researcher Masaki Yuki, a behavioral scientist at Hokkaido University in Japan ... In Japan, emoticons tend to emphasize the eyes, such as the happy face (^_^) and the sad face (;_;). "After seeing the difference between American and Japanese emoticons, it dawned on me that the faces looked exactly like typical American and Japanese smiles," he said.'"

Ollabelle writes "It's always been a bit of a mystery why plants absorb red and blue light, reflecting green, when the sun emits the peak energy of the visible spectrum in the green. A new theory offers one possible answer: that the first chlorophyll-utilizing microbes evolved to exploit the red-and-blue light that older green-absorbing microbes didn't use, eventually out-competing them through greater efficiency and the rise of oxygen."

jas_public writes "Since the human and chimp families split about 6 million years ago, chimpanzee genes seem to have evolved more than human genes. The results, detailed in the Proceedings of the National Academy of Sciences, go against the conventional wisdom that humans are the result of a high degree of genetic selection, evidenced by our relatively large brains, cognitive abilities, and bipedalism. The researchers found that 'substantially more genes in chimps evolved in ways that were beneficial than was the case with human genes.'"

anthemaniac writes "Computerized projections in sports are nothing new, but Bruce Bukiet of the New Jersey Institute of Technology has developed a model that seems to work pretty well. He projects how many games a Major League Baseball team will win by factoring in how each hitter ought to do against each pitcher in every game. His crystal ball says the Yankees will win 110 games this year, a pretty safe bet, many might agree. But he also projects all the divisional winners. He claims to be right more than wrong in five of the past six years."

anthemaniac writes "Scientists have long puzzled over how some dinosaurs and other creatures survived the asteroid impact that supposedly caused the KT mass extinction 65 million years ago and wiped out all the big dinosaurs. One idea has been that smaller animals, including mammals, could have endured the fallout, the big chill, the subsequent volcanoes, and whatever else by burrowing. Now scientists have come up with the first evidence of burrowing dinosaurs. They speculate that underground dens might explain how some dinosaurs got through long, dark winters at high latitudes, too."

anthemaniac writes "Playing video games that involve firing guns (Gears of War, Halo, take your pick) can improve eyesight, according to a new study. From the article: 'People who started out as non-gamers and then received 30 hours of training on first-person action video games showed a substantial increase in their ability to see objects accurately in a cluttered space, compared to non-gamers given the same test.' The games push the brain to the limit, the thinking goes, and it adapts by developing better spatial resolution. The effect was not duplicated in more sedate games like Tetris."

anthemaniac writes "Seismic observations reveal a huge reservoir of water in Earth's mantle beneath Asia. It's actually rock saturated with water, but it's an ocean's worth of water ... as much as is in the whole Arctic Ocean. How did it get there? A slab of water-laden crust sank, and the water evaporated out when it was heated, and then it was trapped, the thinking goes. The discovery fits neatly with the region's heavy seismic activity and fits neatly with the idea that the planet's moving crustal plates are lubricated with water."

amigoro writes to tell us about a study for the US Department of Energy, led by MIT, indicating that geothermal energy could account for 10% of energy production in the US by 2050. The study concludes that geothermal is proven, could impose markedly lower environmental impacts than fossil-fuel and nuclear power plants, and is likely to be cost-competitive with the alternatives. This coverage in LiveScience points out how big a player geothermal already is in the US: "The United States is the world's biggest producer of geothermal energy. Nafi Toksöz, a geophysicist at MIT, noted that the electricity produced annually by geothermal plants now in use in California, Hawaii, Utah, and Nevada is comparable to that produced by solar and wind power combined."

An anonymous reader writes "LiveScience is reporting that it may be possible for two snowflakes to be alike after all. For anyone who studies probability, this seems reasonable, given that the article mentions that 10^24 snowflakes fall in any given year. The article contains links to fascinating snowflake pictures. From the article: 'A typical snow crystal weighs roughly one millionth of a gram. This means a cubic foot of snow can contain roughly one billion crystals ... "It is probably safe to say that the possible number of snow crystal shapes exceeds the estimated number of atoms in the known universe," Nelson said. Still, while "no two snowflakes are alike" might hold true for larger snowflakes, Nelson figures it might ring false for smaller crystals that sometimes fall before they have a chance to fully develop. "How likely is it that two snowflakes are alike? Very likely if we define alike to mean that we would have trouble distinguishing them under a microscope and if we include the crystals that hardly develop beyond the prism stage--that is, the smallest snow crystals," Nelson said.'"

If you're thinking of aiming for the prize, pick the right field. Nobel laureates in physics lived nearly a year longer than winners in chemistry."

An anonymous reader writes "The White House has begun implementing a new policy toward the U.S. Geological Survey, in which all scientific papers and other public documents by USGS scientists must be screened for content.

Subjects fitting this description might include global warming, or research on the effects of oil drilling in the Alaska National Wildlife Reserve."

anthemaniac writes "Researchers for at least two decades have used acoustic levitation to suspend light materials without a container. Wenjun Xie, a materials physicist at Northwestern Polytechnical University in China, has previously used ultrasound fields to levitate globs of iridium and mercury, very heavy materials. Now the scientist has performed the feat with live animals. From the story: 'Xie and his colleagues employed an ultrasound emitter and reflector that generated a sound pressure field between them. The emitter produced roughly 20-millimeter-wavelength sounds, meaning it could in theory levitate objects half that wavelength or less.' Apparently the ants, spiders and ladybugs endured the trick just fine, but the fish didn't do so well due to lack of water."

Looks like this little dog is on the comeback trail."

BostonBTS writes "IntelliOne Technologies has just launched a real-world test of Need4Speed, a real-time traffic-monitoring system that tracks drivers' cell phones. From their website: 'Unlike any other solution available today, the IntelliOne Roadway Speed Measurement System produces live roadway speeds for all highways and surface streets where mobile phone coverage exists, accurate to within three miles per hour.' Of course, any compulsory phone-tracking system raises privacy concerns. According to an article on LiveScience, 'the personal identification data of users will be stripped from cell phone signals before they are processed by IntelliOne's software.' The cell phone companies have this data, but IntelliOne says they won't be keeping their copy."

9x320 writes "The chicken restaurant chain Zaxby's has started to use computers with software by Hyperactive Technologies to direct employees what to do and when to do it, and to decide how many should come to work. The computer works through the use of sensors, analysis of historic data, and touchscreens. The article compares the software to that in a science fiction novel published only just a few years ago, except the computer, Manna, also carried a voice synthesizer."

anthemaniac writes "Hybrid cars are all the rage. Now comes a hybrid scooter. It gets beyond ethanol and lots of batteries, though, running on a hydrogen fuel cell that charges a battery. During braking, energy is also harnessed. All this and speedy too, says inventor Crijn Bouman of Delft University of Technology in the Netherlands. For now, however, the prototype lacks one crucial component: the hydrogen fuel cell! It's coming, Bouman says. Yes, just like $5/gal gas..."

anthemaniac writes "Last year scientists recovered soft tissue from a T. rex. Now LiveScience is reporting that researchers have found fossilized bone marrow, the first discovery this this type of soft tissue, in frog and salamander fossils dating back 10 million years. Since the bone marrow was discovered 'in an environment vastly different form the one in which the T. rex soft tissue was found,' scientists now hope they'll find soft tissue in other environments and maybe from ancient mammals."

anthemaniac writes "A reptile that lived 225 million years ago had triangular-shaped wings like the delta-wings of some jets. At least that's what a new computer model suggests. Researcher have generated several possible shapes for the wings of Sharovipteryx mirabili before, so this is just the latest guess (based on one fossil). Last fall NatGeo reported that the first biplane configuration was on a dinosaur. Maybe airplane designers should delve into the fossil record a little more."

electric_mongoose writes "NewScientistTech has a fascinating story about a paralysed man who can control a computer and robot arm using electrodes implanted in his brain. The electrodes measure neural signals generated when he concentrates on trying to move one of his paralysed limbs and software translates these imagined gestures into the movement of an on-screen cursor or a robotic arm. Other researchers have also revealed a way to dramatically boost the efficiency of similar brain implants in monkeys." If you don't have a handy human brain to play with, 9x320 writes points to a report on LiveScience of Wim van Eck's graduation project: a computer game similar to Pac-Man controlled, not by conventional computer code, but by the brain of an insect. From the article:"Instead of computer code, I wanted to have animals controlling the ghosts. To enable this, I built a real maze for the animals to walk around in, with its proportions and layout matching the maze of the computer game. The position of the animals in the maze is detected using colour-tracking via a camera, and linked to the ghosts in the game. This way, the real animals are directly controlling the virtual ghosts."

An anonymous reader writes "In the 1966 movie "Fantastic Voyage," scientists enter the submarine Proteus, which is miniaturized so they can go inside the body of Jan Benes and save him. While such feats may be a ways off, a new smart pill "enters and exits the body through preexisting orifices" and reports on what it finds along the way, including temperature and pH. Sounds a bit creepy, but apparently it can lickety-split diagnose a disease that otherwise requires lots of uncomfortable probing."

John3 writes "Some people are OK with voluntarily implanting themselves with RFID chips, but how about making RFID implantation mandatory for immigrant and guest workers? VeriChip Corporation chairman Scott Silverman has proposed implanting RFID chips to register workers as they cross the border. According to Silverman, 'We have talked to many people in Washington about using it...' Privacy advocates see this move by VeriChip as a way to introduce their product to Latin America after a lukewarm reception in North America. Would immigrant workers trade their privacy for the opportunity to work in the U.S.? If this type of tracking is enacted, how long before the government decides to start tracking others for various purposes (for example, pedophiles who are released from prison)?"

An anonymous reader writes "Slashdotters are certified geeks, but apparently there's a bunch of other people out there who are very interested in science, technology, politics and culture but they don't want to be known as geeks. A media consulting firm called OMD did a study for the company that owns Space.com and LiveScience. They conclude that 60 million Americans can be called "intellectually curious." Intellectually, I'm curious what that makes the rest of them."

[TheBORG] writes "Professor David Nutt, a psychopharmacologist at the University of Bristol in the UK, believes that there is no scientific reason why 'synthehol' (a science-fictional substitute for alcohol that appears in Star Trek:The Next Generation television series) cannot be created now. It will allow drinkers to experience all of the enjoyable, intoxicating effects of alcohol without unpleasant side-effects like hangovers." Of course, there's still the real deal, Romulan Ale, for when you want a splitting headache in the morning.

starexplorer2001 writes "An object called the 10th planet by some astronomers is not as large as previously thought. New images of 2003 UB313 (aka Xena) were delivered by the Hubble Telescope and showed up as only 1.5 pixels! Now, some are calling to demote Pluto and kill Xena."

valamaldoran writes "Looks like organic computers aren't too far off. Live Science has an interesting article about fusing brain neurons with silicon chips. From the article: 'The achievement could one day enable the creation of sophisticated neural prostheses to treat neurological disorders or the development of organic computers that crunch numbers using living neurons.'"
