astroengine writes "Pulling from 20 years of research since the first discoveries of planets beyond our solar system, scientists have concluded that Earth and its sibling worlds comprise what appears to be a relatively rare breed in a diverse cosmic zoo that includes a huge variety of planet sizes, orbits and parent stars. The most common systems contain one or more planets one to three times bigger than Earth, all orbiting much closer to their parent stars than Earth circles the sun, says astronomer Andrew Howard, with the University of Hawaii."

mikejuk writes with news of an advancement for homomorphic encryption and open source: "To be fully homomorphic the code has to be such that a third party can add and multiply numbers that it contains without needing to decrypt it. In other words they can change the data by working with just the encrypted version. This may sound like magic but a fully homomorphic scheme was invented in 2009 by Craig Gentry. This was a step in the right direction but the problem was that it is very inefficient and computationally intensive. Since then there have been a number of improvements that make the scheme practical in the right situations Now Victor Shoup and Shai Halevi of the IBM T J Watson Research Center have released an open source (GPL) C++ library, HElib, as a Github project. The code is said to incorporate many optimizations to make the encryption run faster. Homomorphic encryption has the potential to revolutionize security by allowing operations on data without the need to decrypt it."

ckwu writes "Since the 1970s, physicists have used laser beams to trap and study small objects, from cells down to individual atoms. Now, electrical engineers at the University of Southern California have developed a simple optical system that assembles hundreds of nanoparticles into two-dimensional structures using a single laser beam and a silicon photonic crystal. This compact optical trap fits on a small chip and could eventually help researchers make materials for new types of sensors, optical devices, and chemical filters."
g01d4 writes "On March 29, 2012, NASA scientists learned that the space agency's Fermi Gamma-ray Space Telescope was headed for a potential conjunction (close approach) with Cosmos 1805, a defunct Russian satellite from the Cold War era. The team knew that the only way to move Fermi would be to fire thrusters designed to move the spacecraft out of orbit at the end of its operating life. On April 3rd, shortly after noon EDT, the space agency fired all thrusters for one second. When it was over, everyone involved 'just sighed with relief that it all went well.' By 1 p.m., the spacecraft had returned to its mission."

ceview writes "This story at Wired seems to have lots of people a bit confused: 'In February 2012, the Nobel Prize-winning physicist Frank Wilczek decided to go public with a strange and, he worried, somewhat embarrassing idea. Impossible as it seemed, Wilczek had developed an apparent proof of "time crystals" — physical structures that move in a repeating pattern, like minute hands rounding clocks, without expending energy or ever winding down. ... [A] Berkeley-led team will attempt to build a time crystal by injecting 100 calcium ions into a small chamber surrounded by electrodes. The electric field generated by the electrodes will corral the ions in a "trap" 100 microns wide, or roughly the width of a human hair. The scientists must precisely calibrate the electrodes to smooth out the field. Because like charges repel, the ions will space themselves evenly around the outer edge of the trap, forming a crystalline ring.' The experimental set up is incredibly delicate (Bose Einstein Condensate), so it implies this perpetual motion effect can't really be used to extract energy. What is your take on it? It's unlike to upend anything, as the article suggests, because at a quantum level things behave weirdly at the best of times. The heavy details are available at the arXiv."
New submitter Doug Otto sends word that researchers working on the ALPHA experiment at CERN are trying to figure out whether antimatter interacts with gravity in the same way that normal matter does. The ALPHA experiment wasn't designed to test for this, but they realized part of it — an antihydrogen trap — is suitable to collect some data. Their preliminary results: uncertain, but they can't rule it out. From the article: "Antihydrogen provides a particularly useful means of testing gravitational effects on antimatter, as it's electrically neutral. Gravity is by far the weakest force in nature, so it's very easy for its effects to be swamped by other interactions. Even with neutral particles or atoms, the antimatter must be moving slowly enough to perform measurements. And slow rates of motion increase the likelihood of encountering matter particles, leading to mutual annihilation and an end to the experiment. However, it's a challenge to maintain any antihydrogen long enough to perform meaningful experiments on it, regardless of its speed. ... The authors of the current study realized that [antiatoms trapped in ALPHA] eventually escaped or were released from this magnetic trap. At that point, they were momentarily in free-fall, experiencing no force other than gravity. The detectors on the outside of ALPHA could then determine if the antihydrogen was rising or falling under gravity's influence, and whether the magnitude of the force was equivalent to the effect on matter."

Chris Hadfield, an astronaut currently on the ISS, described it in his Twitter feed as 'a small stone from the universe.' He also said he was glad it didn't hit the hull. Jim Scotti, a planetary scientist from the University of Arizona, thinks the object may have had a different origin: 'It's unlikely this was caused by a meteor; more likely a piece of man-made space debris in low Earth orbit.'"
Velcroman1 writes "Following the historic first rocket-powered flight of its SpaceShipTwo vehicle, Virgin Galactic plans to build a fleet of spaceships and begin ferrying hundreds of tourists into space in 2014. And then? A whole new kind of spacecraft, Sir Richard Branson said. 'We'll be building orbital spaceships after that,' Branson told Fox News Tuesday, 'so that people who want to go for a week or two can.' Assuming the cost is on the same scale, would you pay a few hundred grand for a few weeks in orbit?"
AmiMoJo writes "The billion-euro Herschel observatory has run out of the liquid helium needed to keep its instruments and detectors at their ultra-low functioning temperature. This equipment has now warmed, meaning the telescope cannot see the sky. Its 3.5m mirror and three state-of-the-art instruments made it the most powerful observatory of its kind ever put in space, but astronomers always knew the helium store onboard would be a time-limiting factor." Reader etash points to a collection of some infrared imagery that Herschel collected.
sl4shd0rk writes "Remember SOPA? If not, perhaps the name Lamar Smith will ring a bell. The U.S. House Committee on Science, Space and Technology chose Smith to Chair as an overseer for the National Science Foundation's funding process. Smith is preparing a bill (PDF) which will require that every grant must benefit 'national defense,' be of 'utmost importance to society,' and not be 'duplicative of other research.' Duplicating research seems reasonable until you consider that this could also mean the NSF will not provide funding for research once someone has already provided results — manufactured or otherwise. A strange target since there is a process in place which makes an effort to limit duplicate funding already. The first and second requirements, even when read in context, still miss the point of basic research. If we were absolutely without-a-doubt-certain of the results, there would be little point in doing the research in the first place."
Zothecula writes "Since the early days of space travel, a consistent complaint has been lousy coffee. Now a group of freshman engineering students at Rice University have developed a simple approach to alleviating this problem. From the article: 'The challenge was to develop a method and equipment that allows astronauts to add liquid ingredients (cream, sweetener, and lemon juice) from a foil package to another that contains black coffee or tea. No spills in microgravity can be allowed, as these have a tendency to migrate into equipment and cause faults. The Rice freshmen designed their system around the existing black coffee pouches. NASA supplied them two-ply heat sealed pouches to hold the sugar syrup and cream. The beverage and condiment pouches all have a septum which allows access to their contents without allowing any of the liquid contents to escape.'"

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."

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.'"
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."
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."
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."
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?"
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.

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."
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.)"
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."
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."
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.'"
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.

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.
ananyo writes "With Taiwan announcing the first case of H7N9 avian flu outside mainland China, researchers have revealed how the virus may spread in China — and beyond. The projections use risk maps developed for human infection by another, well-established avian flu — H5N1. Indeed, when human cases of H7N9 are overlaid on a risk map, they appear to fall within the highest risk areas for H5N1. The map suggests that high-risk areas for H7N9 might include Shandong province (where the first case was reported 23 April) and a belt extending around the Bohai sea to Liaoning province in the north. Though there has been no evidence of sustained human-to-human spread of H7N9 so far, researchers have analyzed airline passenger data for China. Eastern China — the epicenter of the current the H7N9 outbreak — is one of the world's busiest hubs for airline traffic. From the Nature story: 'A quarter of the global population outside of China lives within two hours of an airport with a direct flight from the outbreak regions, and 70% if a single connecting flight is included.'"
An anonymous reader writes "Matter and antimatter are thought to have existed in equal amounts at the beginning of the Universe, but today the Universe appears to be composed essentially of matter. By studying subtle differences in the behavior of particles and antiparticles, experiments at the LHC are seeking to cast light on this dominance of matter over antimatter. Now the LHCb experiment has observed a preference for matter over antimatter known as CP-violation in the decay of neutral B0s particles. The results are based on the analysis of data collected by the experiment in 2011."

Called SDSSJ1506+54, this galaxy generates a huge quantity of infrared radiation, the majority being generated by a compact region at its core. NASA's Wide-field Infrared Survey Explorer first spotted the galactic oddity and Hubble confirmed the maelstrom of stellar birthing near its core. But the most amazing thing? This galaxy is the 'greenest' factory yet discovered — it uses 100 percent of all the available hydrogen to supply the protostars, leaving no waste. 'This galaxy is remarkably efficient,' said lead scientist Jim Geach of McGill University in a NASA news release. 'It's converting its gas supply into new stars at the maximum rate thought possible.'"
MightyMait writes "A study from a team at McGill University has found Tetris to be a good treatment for lazy eye. 'Armed with a special pair of video goggles they set up an experiment that would make both eyes work as a team. Nine volunteers with amblyopia were asked to wear the goggles for an hour a day over the next two weeks while playing Tetris, the falling building block video game. The goggles allowed one eye to see only the falling objects, while the other eye could see only the blocks that accumulate on the ground in the game. For comparison, another group of nine volunteers with amblyopia wore similar goggles but had their good eye covered, and watched the whole game through only their lazy eye. At the end of the two weeks, the group who used both eyes had more improvement in their vision than the patched group (abstract).' As someone born with crossed-eyes who underwent surgery as an infant and has lived with a lazy eye his whole life (without 3-D vision), the prospect of fixing my vision by playing Tetris is an enticing one."

In a mouse model of pancreatic cancer, researchers have shown that bacteria can deliver deadly radiation to tumours — exploiting the immune suppression that normally makes the disease so intractable. The researchers coated the bacterium Listeria monocytogenes with radioactive antibodies and injected the bacterium into mice with pancreatic cancer that had spread to multiple sites. After several doses, the mice that had received the radioactive bacteria had 90% fewer metastases compared with mice that had received saline or radiation alone."
new submitter heybiff writes "It is the time of year where students are scrambling for extra credit assignments to boost grades. As a middle school science teacher, I want to accommodate them, while still keeping science involved; and book reports are a popular activity in my school. Unfortunately, I have only been able to come up with a short list of science related books that a 11-14 year old would or could read in their free time: Ender's Game, Hitchhiker's Guide. What books would you recommend as a good read for an extra credit book report, that would still involve a strong science twist or inspire a student's interest in science? The book must be in print, science related, fiction or non-fiction, and not be overtly objectionable or outright banned. I look forward to the submissions." "Outright banned" actually seems a rich vein on which to draw; note that not even Ender's Game is safe.

Researchers at the university say that it will take years to recover their work. Many of the animals at the facility are genetic models for psychiatric disorders such as autism and schizophrenia. Some of the mice removed by activists were delicate mutants and immunosuppressed 'nude' mice, which die very quickly outside controlled environments. No arrests have been made following the 12-hour drama, which took place on Saturday, although the university says that it will press charges against the protesters. The attack was staged by the animal-rights group that calls itself Fermare Green Hill (or Stop Green Hill), in reference to the Green Hill dog-breeding facility near Brescia, Italy, which it targets for closure."

Bigelow will be performing the study for free too. Robert Bigelow chatted with a radio host a few weeks ago about Bigelow's long-term space plans. They include refueling depots and a commercial moon base, since NASA isn't planning to go there.
colinneagle writes "During a recent trip to an eye doctor, I noticed that she was still using Windows XP. After I suggested that she might need to upgrade soon, she said she couldn't because she couldn't afford the $10,000 fee involved with the specialty medical software that has been upgraded for Windows 7. Software written for medical professionals is not like mass market software. They have a limited market and can't make back their money in volume because there isn't the volume for an eye doctor's database product like there is for Office or Quicken. With many expecting Microsoft's upcoming end-of-support for XP to cause a security nightmare of unsupported Windows devices in the wild, it seems a good time to ask how many users may fall into the category of wanting an upgrade, but being priced out by expensive but necessary third-party software. More importantly, can anything be done about it?"

Nerval's Lobster writes "Samsung is testing a way to control your mobile device with your brainwaves. If that project succeeds, it would truly be a case of science fiction brought to real life. According to MIT Technology Review, Samsung's Emerging Technology Lab is collaborating with Roozbeh Jafari, assistant professor of electrical engineering at the University of Texas, Dallas, on the early-stage research. That research involves placing a cap 'studded with EEG-monitoring electrodes' atop the head of a convenient subject, who then concentrates on an onscreen icon blinking at a particular rate. Concentrate hard enough, and the subject can launch and interact with applications. However, Samsung also indicated that mind-controlled mobile devices are quite a ways off, if they ever appear in a market-ready form at all. 'Several years ago, a small keypad was the only input modality to control the phone, but nowadays the user can use voice, touch, gesture, and eye movement to control and interact with mobile devices,' Insoo Kim, Samsung's lead researcher, told the Review. 'Adding more input modalities will provide us with more convenient and richer ways of interacting with mobile devices.' In any case, it's a crazy concept, the sort of thing Philip K. Dick might have written up as a short story; but it's one evidently grounded in reality."
An anonymous reader writes "A single equation grounded in basic physics principles could describe intelligence and stimulate new insights in fields as diverse as finance and robotics, according to new research, reports Inside Science. Recent work in cosmology has suggested that universes that produce more entropy (or disorder) over their lifetimes tend to have more favorable properties for the existence of intelligent beings such as ourselves. A new study (pdf) in the journal Physical Review Letters led by Harvard and MIT physicist Alex Wissner-Gross suggests that this tentative connection between entropy production and intelligence may in fact go far deeper. In the new study, Dr. Wissner-Gross shows that remarkably sophisticated human-like "cognitive" behaviors such as upright walking, tool use, and even social cooperation (video) spontaneously result from a newly identified thermodynamic process that maximizes entropy production over periods of time much shorter than universe lifetimes, suggesting a potential cosmology-inspired path towards general artificial intelligence."
After high winds (up to 140mph) delayed yesterday's scheduled launch (itself a re-do because of a cabling problem), Orbital Science's Antares rocket has made it to space. This launch was a test run, but Antares is intended to launch supplies to the ISS. Space.com reports: "The third try was the charm for the private Antares rocket, which launched into space from a new pad at NASA's Wallops Flight Facility, its twin engines roaring to life at 5 p.m. EDT (2100 GMT) to carry a mock cargo ship out over the Atlantic Ocean and into orbit. The successful liftoff came after two delays caused by a minor mechanical glitch and bad weather." Congratulations to all involved.
