Physicists close two loopholes while violating local realism
(PhysOrg.com) -- The latest test in quantum mechanics provides even stronger support than before for the view that nature violates local realism and is thus in contradiction with a classical worldview. By performing an experiment in which photons were sent from one Canary Island to another, physicists have shown that two of three loopholes can be closed simultaneously in a test that violates Bell's inequality (and therefore local realism) by more than 16 standard deviations. Performing a Bell test that closes all three loopholes still remains a challenge, but the physicists predict that such an experiment might be "on the verge of being possible" with state-of-the-art technology.
IBM's breakthrough chip technology lights the path to exascale computing
(PhysOrg.com) -- IBM scientists today unveiled a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light (instead of electrical signals), resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies.
US deploys 'game-changer' weapon to Afghanistan
It looks and acts like something best left in the hands of Sylvester Stallone's "Rambo," but this latest dream weapon is real -- and the US Army sees it becoming the Taliban's worst nightmare.
Partial reversal of aging achieved in mice
(PhysOrg.com) -- Harvard scientists at Dana-Farber Cancer Institute say they have for the first time partially reversed age-related degeneration in mice, resulting in new growth of the brain and testes, improved fertility, and the return of a lost cognitive function.
New life form found on Earth: Deadly arsenic breathes life into organisms (Update, Video)
(PhysOrg.com) -- Evidence that the toxic element arsenic can replace the essential nutrient phosphorus in biomolecules of a naturally occurring bacterium expands the scope of the search for life beyond Earth, according to Arizona State University scientists who are part of a NASA-funded research team reporting findings in the Dec. 2 online Science Express.
Discovery triples number of stars in universe
Astronomers have discovered that small, dim stars known as red dwarfs are much more prolific than previously thought—so much so that the total number of stars in the universe is likely three times bigger than realized.
A step toward fusion power: MIT advance helps remove contaminants that slow fusion reactions
The long-sought goal of a practical fusion-power reactor has inched closer to reality with new experiments from MIT’s experimental Alcator C-Mod reactor, the highest-performance university-based fusion device in the world.
NASA creates buzz with 'extraterrestrial' announcement
The US space agency has created a buzz with its announcement of a press conference Thursday to discuss a scientific finding that relates to the hunt for life beyond the planet Earth.
US Air Force connects 1,760 PlayStation 3's to build supercomputer
(PhysOrg.com) -- About the 33rd largest supercomputer in the world right now is the US Air Force Research Laboratory's (AFRL) newest system, which has a core made of 1,760 Sony PlayStation 3 (PS3) consoles. In addition to its large capacity, the so-called "Condor Cluster" is capable of performing 500 trillion floating point operations per second (TFLOPS), making it the fastest interactive computer in the entire US Defense Department.
Sahara desert project aims to power half the world by 2050
(PhysOrg.com) -- A joint project by universities in Algeria and Japan is planning to turn the Sahara desert, the largest desert in the world, into a breeding ground for solar power plants that could supply half the world’s electrical energy requirements by 2050.
Milky Way stars move in mysterious ways
Rather than moving in circles around the center of the Milky Way, all the stars in our Galaxy are travelling along different paths, moving away from the Galactic center. This has just been evidenced by Arnaud Siebert and Benoit Famaey, astronomers at the Strasbourg Astronomical Observatory, and by their colleagues in other countries. This strange behavior may be due to perturbation caused by the central bar and spiral arms of our Galaxy, forcing stars to leave their normal circular course and take an outward path.
Apple patents an inexpensive 3-D projection system
(PhysOrg.com) -- The U.S. patent office has granted Apple a patent for a 3-D projection system that doesn't require the use of bulky 3-D glasses. This gives the viewer more freedom of movement and viewing angles.
Meditation isn't just about relaxing
Meditation is a brain-boosting, stress-busting activity that is now embraced by everyone from the U.S. military to corporate executives. And if you're living a busy, hectic life - and can't fathom finding time to sit cross-legged in a quiet room - you're an ideal candidate too.
Venus holds warning for Earth
(PhysOrg.com) -- A mysterious high-altitude layer of sulphur dioxide discovered by ESA's Venus Express has been explained. As well as telling us more about Venus, it could be a warning against injecting our atmosphere with sulphur droplets to mitigate climate change.
Pheromones a myth in mammals
Something just didn’t smell right to Richard Doty. It was 1976 when the director of the Smell and Taste Center at Penn’s School of Medicine first started raising a stink about the existence of pheromones.
Legalizing child pornography is linked to lower rates of child sex abuse: study
Could making child pornography legal lead to lower rates of child sex abuse? It could well do, according to a new study by Milton Diamond, from the University of Hawaii, and colleagues.
Researchers discover a way to simultaneously desalinate water, produce hydrogen and treat wastewater
(PhysOrg.com) -- Fresh water and reusable energy. Humans are on a constant hunt for a sustainable supply of both. Water purification requires a lot of energy, while utility companies need large amounts of water for energy production. Their goal is to find a low-energy-required treatment technology. Researchers from the University of Colorado Denver College of Engineering and Applied Science may have discovered an answer.

Graphene: Scientists figure out how to shatter the world's strongest material
In 2008, experiments at The Fu Foundation School of Engineering and Applied Science at Columbia University established pure graphene, a single layer of graphite only one atom thick, as the strongest material known to mankind. This raised a question for Chris Marianetti, Assistant Professor in Columbia Engineering's Department of Applied Physics and Applied Mathematics: how and why does graphene break?
Scientists discover new mechanism for controlling blood sugar level
Medical scientists at the University of Leicester have identified for the first time a new way in which our body controls the levels of sugar in our blood following a meal.
