First time accepted submitter smazsyr writes "An international collaboration of scientists is reporting in landmark detail the decay process of a subatomic particle called a kaon – information that may help answer fundamental questions about how the universe began. The calculation in the study required 54 million processor hours on the IBM BlueGene/P supercomputer at Argonne National Laboratory, the equivalent of 281 days of computing with 8,000 processors. 'This calculation brings us closer to answering fundamental questions about how matter formed in the early universe and why we, and everything else we observe today, are made of matter and not anti-matter,' says a co-author of the paper."

scibri writes, quoting Nature: "A loose coalition of eco-anarchist groups is increasingly launching violent attacks on scientists. A group calling itself the Olga Cell of the Informal Anarchist Federation International Revolutionary Front has claimed responsibility for the non-fatal shooting of a nuclear-engineering executive on 7 May in Genoa. The same group sent a letter bomb to a Swiss pro-nuclear lobby group in 2011; attempted to bomb IBM's nanotechnology laboratory in Switzerland in 2010; and has ties with a group responsible for at least four bomb attacks on nanotechnology facilities in Mexico. Another branch of the group attacked railway signals in Bristol, UK, last week in an attempt to disrupt employees of nearby defense technology firms (no word on whether anyone noticed the difference between an anarchist attack and a normal Wednesday on the UK's railways). A report by Swiss intelligence says such loosely affiliated groups are increasingly working together."
ericjones12398 writes "Just one decade ago, sequencing an entire human genome cost upwards of $10 million and took about three years to complete. Now, several companies are racing to provide technology that can sequence a complete human genome in one day for less than $1,000. 'A genome sequence for $1,000 was a pipe dream, just a few years ago,' said Dr. Richard Gibbs, director of the Human Genome Sequencing Center at Baylor College of Medicine, 'A $1,000 genome in less than one day was not even on the radar, but will transform the clinical applications of sequencing."
ananyo writes "Chemists in the UK have made a five-ring polyaromatic hydrocarbon and dubbed it 'olympicene'. The molecule is just a couple of nanometers wide and can be regarded as a little fragment of graphene. Strictly speaking, of course, the molecule might constitute an 'unofficial use' of the motif and land the scientists in court for copyright infringement."
First time accepted submitter gbrennan123 writes "Researchers at NYU School of Medicine have identified a single gene that simultaneously controls inflammation, accelerated aging and cancer. From the article: '"This was certainly an unexpected finding," said principal investigator Robert J. Schneider, PhD, the Albert Sabin Professor of Molecular Pathogenesis, associate director for translational research and co-director of the Breast Cancer Program at NYU Langone Medical Center. "It is rather uncommon for one gene to have two very different and very significant functions that tie together control of aging and inflammation. The two, if not regulated properly, can eventually lead to cancer development. It's an exciting scientific find."'"
First time accepted submitter funge writes "The Economist has an article on Work and play: The gamification of hiring about a start-up that lets you play games to show off your talents to prospective employers. From the article: 'The rules of Happy Hour are deceptively simple. You are a bartender. Your challenge is to tell what sort of drink each of a swelling mob of customers wants by the expressions on their faces. Then you must make and serve each drink and wash each used glass, all within a short period of time. Play this video game well and you might win a tantalizing prize: a job in the real world.'"
First time accepted submitter johnsnails writes "A German 16-year-old, Shouryya Ray, solved two fundamental particle dynamic theories posed by Sir Isaac Newton, which until recently required the use of powerful computers. He worked out how to calculate exactly the path of a projectile under gravity and subject to air resistance. Shouryya solved the problem while working on a school project. From the article: 'Mr Ray won a research award for his efforts and has been labeled a genius by the German media, but he put it down to "curiosity and schoolboy naivety." "When it was explained to us that the problems had no solutions, I thought to myself, 'well, there's no harm in trying,'" he said.'"
sciencehabit writes "China and India are some of the world's top polluters, with countless cars, factories, and households belching more than 2 million metric tons of carbon soot and other dark pollutants into the air every year. The pall hanging over the region has come to be known as 'the Asian brown cloud.' These pollutants aren't just bad news for the countries themselves. A new study reveals that they can affect climate thousands of kilometers away, warming the United States by up to 0.4C by 2024, while cooling other regions (abstract)."
An anonymous reader writes "People who are outgoing, optimistic, easygoing, and have a good sense of humor and a large social network are likely to live longer than others who don't possess these personality traits, according to new research (abstract). The study reveals how saying, 'It's in their genes' could refer to more than just genetic variations that give a physiological advantage, like having high levels of HDL ('good') cholesterol, because people with positive personality traits appear to live longer than those who do not."
Hexydes writes "Early in the morning (5:53 am EST) on May 26th, 2012, NASA gave the go-ahead for the Expedition 31 crew to begin the procedure to open the hatch on the Dragon capsule, now directly attached to the ISS. 'The hatch opening begins four days of operations to unload more than 1,000 pounds of cargo from the first commercial spacecraft to visit the space station and reload it with experiments and cargo for a return trip to Earth. It is scheduled for splashdown several hundred miles west of California on May 31. Wearing protective masks and goggles, as is customary for the opening of a hatch to any newly arrived vehicle at the station, Pettit entered the Dragon with Station Commander Oleg Kononenko. The goggles and masks will be removed once the station atmosphere has had a chance to mix air with the air inside the Dragon itself.' Here is a video of the procedure."
hessian writes "Scientists at the Georgia Institute of Technology achieved a 17-percent increase in boiling efficiency by using an acoustic field to enhance heat transfer. The acoustic field does this by efficiently removing vapor bubbles from the heated surface and suppressing the formation of an insulating vapor film."
gollum123 writes with this excerpt from the NY Times: "For more than a decade, almost all processed foods in the United States — cereals, snack foods, salad dressings — have contained ingredients from plants whose DNA was manipulated in a laboratory. Regulators and many scientists say these pose no danger. But as Americans ask more pointed questions about what they are eating, popular suspicions about the health and environmental effects of biotechnology are fueling a movement to require that food from genetically modified crops be labeled, if not eliminated. The most closely watched labeling effort is a proposed ballot initiative in California that cleared a crucial hurdle this month, setting the stage for a probable November vote that could influence not just food packaging but the future of American agriculture. Tens of millions of dollars are expected to be spent on the election showdown. It pits consumer groups and the organic food industry, both of which support mandatory labeling, against more conventional farmers, agricultural biotechnology companies like Monsanto and many of the nation's best-known food brands like Kellogg's and Kraft."
Today at 9:56AM EDT (13:56 GMT) the robotic arm on the International Space Station successfully captured SpaceX's Dragon capsule. It's the first time a commercial craft has connected with the ISS, and the first time a spacecraft made in the U.S. has gone to the station since the retirement of the shuttle. The approach was delayed temporarily as engineers worked out bad sensor readings due to light reflected off the ISS's Kibo laboratory. "To work around the problem, SpaceX narrowed the field of view for the laser sensor so that it wouldn't pick up light from the offending reflector. Dragon then returned to the 30-meter checkpoint and moved in for the final approach." If all goes well today, the capsule will most likely be opened tomorrow. Video of the operation is being broadcast live on NASA TV.
ananyo writes "The battle for the world's largest radio telescope has ended in a draw. As an earlier Slashdot story suggested, South Africa and Australia are to split the Square Kilometre Array, a €1.5 billion (US$1.9 billion) project made up of 3,000 15-meter-wide dishes and an even larger number of simple antennas. The decision was announced at a meeting outside of Amsterdam in the Netherlands, following a vote by SKA's international board."
Marian the Librarian writes "UCSF is among the first public institutions to adopt an open access policy, and is the largest scientific institution to have such a policy. The policy, voted unanimously by the faculty, will allow UCSF authors to put electronic versions of their published scientific articles on an open access repository making their research findings freely available to the public. Dr. Richard A. Schneider, who led the initiative, said, 'Our primary motivation is to make our research available to anyone who is interested in it, whether they are members of the general public or scientists without costly subscriptions to journals. The decision is a huge step forward in eliminating barriers to scientific research.'"
