SpaceShipTwo Tests Its Rocket Engine and Goes Supersonic 103

ehartwell writes "It's official. This morning, after WhiteKnightTwo released SpaceShipTwo at an altitude of around 50,000 feet, pilots Mark Stucky and Mike Alsbury ignited the engine for a roughly 16-second blast. After the engine cutoff, the plane coasted back to its landing back at the Mojave airport. Virgin Galactic tweeted that the pilots confirmed 'SpaceShipTwo exceeded the speed of sound on today's flight!' Its predecessor, SpaceShipOne, first went supersonic December 17, 2003."

Genetically Modified Plants To Produce Natural Lighting 328

kkleiner writes "A team has launched a crowdsourcing campaign to develop sustainable natural lighting by using a genetically modified version of the flowering plant Arabidopsis. Using the luciferase gene, the enzyme responsible for making fireflies glow, the researchers will design, print, and transform the genes into the target plant. The project, which was recently launched on Kickstarter, has already raised over $100k with over a month left to go."

Nearest Alien Planet Gets New Name 185

SchrodingerZ writes "The nearest planet outside our solar system has recently been named Albertus Alauda. Originally named Alpha Centauri Bb, the planet is the closest known planet not orbiting the Sun, being a mere 4.3 light years away. The name comes from Jay Lark, who won the naming contest held by Uwingu starting last month and ending on April 22. Lark remarks that the name comes from the Latin name of his late grandfather, stating, "My grandfather passed away after a lengthy and valiant battle with cancer; his name in Latin means noble or bright and to praise or extol." The competition for naming the planet came from Uwing, a company which used the buying of name proposals and votes to fund grants for future space exploration ventures. Albertus Alauda won the competition with 751 votes, followed by Rakhat with 684 votes, and Caleo, with 622 votes."

Experiment Will Determine Dinosaur's Skin Color 98

AchilleTalon writes "One of the only well preserved dinosaur skin samples ever found is being tested at the Canadian Light Source (CLS) synchrotron to determine skin color and to explain why the fossilized specimen remained intact after 70-million years. University of Regina physicist Mauricio Barbi said the hadrosaur, a duck-billed dinosaur from the Late Cretaceous period (100-65 million years ago), was found close to a river bed near Grand Prairie, Alberta."

EPA Report That Lowers Methane-Leak Estimates Further Divides Fracking Camps 127

gmfeier writes "The EPA has significantly lowered its estimate of how much methane leaks during natural gas production. This has major implications for the fracking debate, but puts the EPA at odds with NOAA. From the article: 'The scope of the EPA's revision was vast. In a mid-April report on greenhouse emissions, the agency now says that tighter pollution controls instituted by the industry resulted in an average annual decrease of 41.6 million metric tons of methane emissions from 1990 through 2010, or more than 850 million metric tons overall. That's about a 20 percent reduction from previous estimates. The agency converts the methane emissions into their equivalent in carbon dioxide, following standard scientific practice.'"

Artificial Skin Sensitivity Rivals That of Human Skin 29

New submitter hebbosome writes "Researchers at Georgia Tech have provided a glimpse of a future full of highly-sensitive robots. Their nanoelectronic pressure sensors, comparable in sensitivity to human skin, are made out of new type of vertical transistor (abstract). 'In Wang’s nanowire transistors, the gate traditionally used in electronics is eliminated. Instead, the current flowing through the nanowires is controlled by the electrical charge generated when strain or force applied is to the transistors.' 'The arrays include more than 8,000 functioning piezotronic transistors, each of which can independently produce an electronic controlling signal when placed under mechanical strain.' They could immediately be used in human-machine interfaces for capturing electronic signatures, and, down the road, in robots and prosthetics."

Space Junk 'Cleaning' Missions Urgently Needed 165

Following a conference on space debris, the European Space Agency has warned that the amount of space junk floating around in orbit is a problem that needs to be dealt with 'urgently.' They are calling for a number of test missions to examine different methods of controlling or removing the debris. "Our understanding of the growing space debris problem can be compared with our understanding of the need to address Earth’s changing climate some 20 years ago," said Heiner Klinkrad, head of the agency's Space Debris office. A couple years ago we discussed an idea for de-orbiting space junk by hitting it with a laser to change its momentum. An Australian company has now received funding from NASA and the Australian government to try just that. "We've been developing tracking systems using lasers for some years, so we can actually track very small objects with a laser rangefinder to very high accuracy. ... If you allow that velocity to change over a period of perhaps 24 hours, then you can get actually a 100-meter shift in the location of an object to deflect it from colliding with another space debris object." Other plans are in development as well, and there currently exists an international guideline saying that new hardware must de-orbit and burn up in the atmosphere after 25 years of operation — but compliance is lagging. Meanwhile, collision events are becoming more common (PDF), and experts worry about the safety of the International Space Station and important satellites. "Their direct costs and the costs of losing them will by far exceed the cost of remedial activities."

'Master Gene' Makes Mouse Brain Look More Human 121

sciencehabit writes "Researchers have found a genetic mutation that causes mammalian neural tissue to expand and fold. When they mutated this gene in mice, the rodents developed brains that look more like ours (abstract). The discovery may help explain why humans evolved more elaborate brains than mice, and it could suggest ways to treat disorders such as autism and epilepsy that arise from abnormal neural development. The findings go against a common conception that 'dumber species will have different genes' for brain development than more intelligent species, Borrell says. He adds that the mechanism could help explain how New World monkeys, with their small, smooth brains, could have evolved from an ancestor with a bigger and more folded brain."

Belief In God Correlates With Better Mental Health Treatment Outcomes 931

Hatta writes "According to researchers from Harvard Medical School, belief in god is correlated with improved outcomes of treatment for depression. Quoting: 'In the study, published in the current issue of Journal of Affective Disorders, researchers comment that people with a moderate to high level of belief in a higher power do significantly better in short-term psychiatric treatment than those without. "Belief was associated with not only improved psychological well-being, but decreases in depression and intention to self-harm," says David H. Rosmarin, Ph.D., an instructor in the Department of Psychiatry at Harvard Medical School.' This raises interesting questions. Does this support the concept of depressive realism? If the association is found to be causal, would it be ethical for a psychiatrist to prescribe religion?"

2014: Planetary Resources To Launch Their First Satellites 76

symbolset writes "Planetary Resources wants to mine asteroids for their sweet, sweet minerals and make a business of it. The sparky little company has been writ up here on Slashdot numerous times. With the backing of such billionaires as Eric Schmidt, Larry Page, James Cameron, and many others, and such luminaries as major NASA project managers, engineers and scientists, you have to think they might have a good shot at it. Recently they picked up a huge engineering, procurement and construction partner: Bechtel. Their operations are already cash-flow positive by selling tech invented to pursue their goals, so they're a legitimate business running lean and intending to make good. Yesterday they announced the plan to launch their first space missions — the Arkyd Series 100 LEO Space Telescopes — as soon as next year. Beginning in 2014 their satellites will be scanning the skies from Low Earth Orbit for lucrative rocks that happen to be heading our way, and incidentally doing for-pay work to keep the lights on. For a reasonable fee they'll sell you the right to retask one of these telescopes to take a picture of anything you want that it can see, for a fair price. The plan is to follow up with harvester craft to go get these asteroids, mulch them, and sell their bits for profit. Some talk has been made of selling what are uncommon terrestrial minerals like gold and platinum, refined on orbit and deorbited at great expense as a business plan, but frankly that's absurd. 'Extraterrestrial Asteroid Bits' ought to go for a higher price on the collector market than gold or platinum ever would, and the temporal preeminence should draw a premium price. 'This 69 mg specimen (769 of 10,000) was one of the first commercially harvested bits of asteroid returned to Earth. Lucite embedded for permanent display, with case. Certificate of authenticity included.'"

Why We'll Never Meet Aliens 629

iggychaos writes "The idea that aliens will come visit us is fundamentally flawed. Paul Tyma ponders the technology that would be required for such an event and examines how evolution of that technology would preclude any reason to actually make the trip. He writes, 'Twenty years ago if I asked you how many feet were in a mile (and you didn't know) you could go to a library and look it up. Ten years ago, you could go to a computer and google it. Today, you can literally ask your phone. It's not a stretch at all with the advent of wearable computing that coming soon - I can ask you that question and you'll instantly answer. ... How would you change if you had instant brain-level access to all information. How would you change if you were twice as smart as you are now. How about ten times as smart? (Don't answer, truth is, you're not smart enough to know). Now, let's leap ahead and think about what that looks like in 100 years. Or 1000. Or whenever it is you'll think we'd have the technology to travel to another solar system. We'd be a scant remnant of what a human looks like today. ... The question of why aliens might 'want to come here' is probably fundamentally flawed because we are forming that question from our current (tiny) viewpoint. The word 'want' might not apply at all to someone 1000 times smarter than us."

New Study Suggests No Shortage of American STEM Graduates 344

An anonymous reader writes "A study released Wednesday by the left-leaning Economic Policy Institute reinforces what a number of researchers have come to believe: that the STEM worker shortage is a myth. The EPI study found that the United States has 'more than a sufficient supply of workers available to work in STEM occupations.' Basic dynamics of supply and demand would dictate that if there were a domestic labor shortage, wages should have risen. Instead, researchers found, they've been flat, with many Americans holding STEM degrees unable to enter the field and a sharply higher share of foreign workers taking jobs in the information technology industry. (IT jobs make up 59 percent of the STEM workforce, according to the study.)"

Earth's Core Far Hotter Than Thought 189

hessian writes "New measurements suggest the Earth's inner core is far hotter than prior experiments suggested, putting it at 6,000C — as hot as the Sun's surface. The solid iron core is actually crystalline, surrounded by liquid. But the temperature at which that crystal can form had been a subject of long-running debate. Experiments outlined in Science used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt."

Europe Needs Genetically Engineered Crops, Scientists Say 586

First time accepted submitter Dorianny writes in with a story about the ongoing battle over genetically engineered crops in Europe. "The European Union cannot meet its goals in agricultural policy without embracing genetically engineered crops (GMOs). That's the conclusion of scientists who write in Trends in Plant Science, a Cell Press publication, based on case studies showing that the EU is undermining its own competitiveness in the agricultural sector to its own detriment and that of its humanitarian activities in the developing world. 'Failing such a change, ultimately the EU will become almost entirely dependent on the outside world for food and feed and scientific progress, ironically because the outside world has embraced the technology which is so unpopular in Europe, realizing this is the only way to achieve sustainable agriculture,' said Paul Christou of the University of Lleida-Agrotecnio Center and Institució Catalana de Recerca i Estudis Avançats in Spain."

Smithsonian Releases 128-Year-Old Recording of Alexander Graham Bell 122

redletterdave writes "Thanks to a newly developed audio extraction technology called optical scanning, the Smithsonian was able to recover the voice of Alexander Graham Bell from one of his hundreds of discs he donated to the museum, which were once considered 'mute artifacts.' Since many of the collected recordings are very fragile due to their age and experimental nature, optical scanning is a non-invasive procedure that creates a high-resolution digital map of the disc or cylinder, which is then reconstructed and used to simulate the motion of a stylus moving through its grooves to reproduce the original audio content. Bell, who created this recording on a wax and cardboard disc on April 15, 1885, can be heard clearly saying, 'In witness whereof — hear my voice, Alexander Graham Bell.'"

Scientists May Have Detected Neutrinos From Another Galaxy 151

The Bad Astronomer writes "A experiment called IceCube — consisting of sensitive light detectors buried deep in the Antarctic ice — has detected two ultra-high-energy neutrinos, each with over a peta-electronVolt of energy (a quadrillion times the energy of a visible light photon), the highest energy neutrinos ever seen. The two events, nicknamed Bert and Ernie, have a 99% chance of originating outside our galaxy, likely created either by a supermassive black hole or an exploding gamma-ray burst."

Harvard To Close New England Primate Research Center 100

sciencehabit writes "Citing an increasingly bleak outlook for federal research funding, Harvard Medical School is shutting down its major primate center, which has recently experienced the departure of several key scientists and an investigation into its handling of animals. In the announcement, which surprised many primate researchers, the school said it will not seek to renew the New England Primate Research Center's (NEPRC's) 5-year grant from the National Institutes of Health (NIH) and will 'wind down operations' at the center in Southborough, Massachusetts, over the next 2 years. The center, which has a nearly 50-year history, had done groundbreaking work on an AIDS vaccine and developed animal models for diseases such as Parkinson's, among other accomplishments."

NASA Lets Us Watch the Sun Spin For 3 Years In 4 Minute Video 34

An anonymous reader writes "Back in February 2010 NASA launched the Solar Dynamics Observatory–a 3-axis stabilized satellite and fully redundant spacecraft. The aim of the SDO is to monitor solar activity and see how that impacts space weather. As part of its observations, the SDO captures an image of the Sun every 12 seconds using the onboard Atmospheric Imaging Assembly, but varies those shots across 10 different wavelengths. NASA has now collected three years worth of image data from the SDO and has put together a video letting us see the Sun spin in all its glory." If you watch closely, you can see individual frames containing the Moon and Venus.
