First 'heavy-fermion' material made in 2D PhysicsWorld Share    
Physicists in Japan have created the first 2D "heavy-fermion" material -- providing the best evidence yet that heavy fermions undergo a quantum phase transition. The material was made using molecular beam epitaxy (MBE), which also allowed the researchers to carry out the first systematic study of how the electronic properties of a heavy-fermion material change when it is made into layers just one molecule thick. The results could help physicists to understand why some other layered materials superconduct at relatively high temperatures. More
Secretary of Energy Steven Chu helps confirm Einstein theory San Francisco Chronicle Share
A UC Berkeley physicist and a Nobel prize-winning colleague now in President Obama's Cabinet report they have confirmed one of Albert Einstein's most revolutionary theories 10,000 times more accurately than ever before. More
Can graphene nanoribbons replace silicon? PhysOrg Share
"Graphene has been the subject of intense focus and research for a few years now," Philip Kim tells PhysOrg.com. "There are researchers that feel that it is possible that graphene could replace silicon as a semiconductor in electronics." Click here to read the associated Physical Review Letters article. More Climate science: Credibility at risk, scientists say ScienceNews Share
Publication of hacked emails exchanged by climate scientists. News accounts of problems in vetting data used in climate-assessment reports. Charges by critics that scientists won't release their raw data so that others might independently vet published analyses of climate trends. Taken together, these events have marred the reputations of climate scientists, the Intergovernmental Panel on Climate Change and perhaps science generally More
Nuclear disarmament science: How to be dumb enough to be smart ScienceNOW Share
As underscored by the announcement by Vice President Joe Biden, the Obama Administration has undertaken a historic effort to cut its nuclear arsenal. The science to do it safely and credibly is ready to go, says a new study presented here at the annual meeting of the American Association for the Advancement of Science. But the surprising political and diplomatic conundrums involved with shrinking the U.S. and Russian stockpiles are numerous and formidable. More WISE sees sky in new light: Big pics Discovery News Share
Peering out across the sky, a new NASA telescope known as WISE (the Wide-field Infrared Survey) is methodically mapping everything radiating in infrared light. Prime catches during its first month of surveys include shots of a newly discovered comet, our neighbor galaxy Andromeda and a relatively nearby cluster of galaxies known as Fornax. NASA released the first batch images. More
Stranger than friction The Columbus Dispatch Share
Every time you tune in to the Winter Olympics, you are watching the laws of physics at work. (And no, we're not talking about Bob Costas' hair.) You see them when a hockey player unloads a wicked slap shot, when a figure skater vaults into a triple axel, and when a ski jumper soars through the frigid air. More Science literacy: U.S. college courses really count ScienceNews Share
Over the past two decades, science literacy in the United States – an estimate of the share of adults who can follow complex science issues and maybe even render an informed opinion on them – has nearly tripled. But, and it's a big but, the proportion of people who fall into this category remains small. Just 28 percent. More |
