New nanolens breaks resolution record Wired UK Share    
A new kind of lens reaches an unprecedentedly sharp focus by giving up on being perfect. The lens is the first ever to help take visual light images of structures smaller than 100 nanometers, which could make it useful for nanotechnology and probing the insides of cells. Read the associated Physical Review Letters abstract. More
Simplifying the process of detecting genuine multiparticle entanglement PhysOrg Share
The ability to entangle particles is considered essential for a number of experiments and applications, but entanglement is still difficult to detect unambiguously. Physicists are now proposing a new method to easily evaluate multiparticle entanglement. Read the associated Physical Review Letters abstract. More
New superconductive properties discovered in old sandwich material PhysOrg Share
Researchers have discovered that a previously known kind of double layered material created using electrostatic doping can be used as a superconductor. More Weird 'unparticle' boosted by Tevatron signal New Scientist Share
Elastic "unparticles" could explain a mysterious signal glimpsed at a particle collider a year ago. That would link a tenuous but intriguing idea to one of the biggest mysteries in physics: why matter prevails over antimatter in the universe. More
Unbound planets could abound in the universe Physics World Share
Ten planets that appear to be drifting in interstellar space have been spotted by an international team of astronomers. The planets are so far from any host stars that they may not orbit a star at all, and could be drifting unbound through space. The team believes that such rogue planets could outnumber normal stars almost 2:1 and their existence could confirm computer simulations of solar-system formation. More Details of Japan earthquake explain its extraordinary strength and unexpectedness Scientific American Share
The first scientific analyses of the deadly earthquake that took place in Japan on March 11 confirm its power and suggest what might happen next. More
Largest-ever survey of cosmic history confirms that dark energy exists, is tearing the universe apart Popular Science Share
After a five-year study of 200,000 galaxies, scientists are more certain than ever that dark energy acts as a repulsive force, tearing the universe apart at an accelerating rate. The research confirms the idea that dark energy dominates gravity throughout the cosmos. But no one has any idea what dark energy actually is or how it works. More Liquid crystals could detect contaminated water New Scientist Share
If you've ever dropped your mobile phone in dishwater, you can now claim you were testing the water for bacterial contamination. It seems liquid crystals, ubiquitous in electronic displays, are the best way to detect water-borne toxins. More
Chu calls NSF's decision to abandon DUSEL 'disappointing' Science Magazine Share
Energy Secretary Steven Chu says that he's "very disappointed" with the National Science Foundation (NSF) for pulling out of a planned $875-million underground science lab in South Dakota. In his most extensive public comments since NSF's oversight body decided in December to walk away from the Deep Underground Science and Engineering Laboratory (DUSEL) project, Chu told a congressional spending panel yesterday that the decision was especially hard to fathom "since [NSF] started it."
