Crystal clarity wins Chemistry Nobel for Israeli The Associated Press via Google Share    
Israeli scientist Daniel Shechtman Wednesday won the 2011 Nobel Prize for Chemistry for the secret of quasicrystals, an atomic mosaic whose discovery overturned theories about solids. Shechtman, aged 70, ran into fierce hostility among fellow chemists after making a eureka-like discovery in 1982 that at the time was dismissed as laughable.

Physics Nobel explainer: Why is expanding universe accelerating? National Geographic Share
What goes up must come down. Few on Earth would argue with the fundamental law of gravity. But the 2011 Nobel Prize in Physics was awarded to three scientists who uncovered a dark side of the force. New Nobel laureates Saul Perlmutter and Adam Riess of the U.S. and Brian Schmidt of Australia contributed to the discovery that the universe is not only expanding but also speeding up. More UT grad student faces trial in Iran, scientists call espionage charges 'ludicrous' Austin American-Statesman Share
As scientists and academics across the world continue to push for his release, a 29-year-old University of Texas physics graduate student faces trial in his native Iran on espionage charges. Omid Kokabee, 29, started attending UT last fall to work on his Ph.D. in optics. More 'Accelerating universe' could be just an illusion MSNBC Share
A new theory suggests that the accelerating expansion of the universe is merely an illusion. Read the associated Physical Review D abstract. More
Trilayer graphene exhibits quantum effect Science News Share
Three could be the magic number for making spintronic devices from thin carbon sheets. Read the associated Physical Review Letters abstract. More Accelerator finds new gear The Wall Street Journal Share
Scientists powered down the nation's largest particle accelerator that for nearly three decades has been revealing insights into the building blocks of matter. But closing the Tevatron accelerator won't mean the end of cutting-edge research at the U.S. Department of Energy's Fermi National Accelerator Laboratory. More Sweet beams: Lasers to measure blood sugar Science News Share
A new, gentler technique for measuring blood sugar uses a pair of laser beams instead of a needle. The device could provide a way for diabetics to monitor their glucose levels without the pain of pricked fingers. Read the abstract of the forthcoming Physical Review E article. More
Prediction or cause? Information theory may hold the key PhysOrg Share
Physicists ponder how to tell the difference between something predicting an event and something actually causing an event. Read the associated Physical Review Letters abstract. More Richard Feynman, the late physicist, is hero of new graphic novel The Washington Post Share
There is a new graphic novel starring a particle physicist. Not, mind you, just any particle physicist. The people’s particle physicist. More
Quantum life: The weirdness inside us NewScientist Share
Ever felt a little incoherent? Or maybe you've been in two minds about something, or even in a bit of delicate state. Well, here's your excuse: perhaps you are in thrall to the strange rules of quantum mechanics. Read the associated Physical Review Letters abstract. More New way to store light could prove useful for optical communication PhysOrg Share
A proof-of-principle experiment has successfully stored optical information as mechanical excitations inside silica microspheres. The microspheres serve as optomechanical resonators, which have cavities that allow the scientists to generate mechanical excitations. Read the associated Physical Review Letters abstract. More
Active galactic nuclei measure the universe Physics World Share
A common type of active galactic nuclei (AGN) could be used as an accurate "standard candle" for measuring cosmic distances - according to astronomers in Denmark and Australia. AGNs are some of the brightest objects in the visible universe and the technique could allow astronomers to determine much larger distances than is possible with current techniques, the scientists say. More Seismologists' trial in Italy highlights need for routine earthquake forecasting, geophysicist says PhysOrg Share
Six Italian seismologists and one government official went on trial for manslaughter in Italy last week. The unusual trial stems from accusations that the seven failed to adequately communicate the potential for a major earthquake to the population around the central Italian town of L'Aquila, which was hit by a devastating magnitude 6.3 earthquake in the predawn hours of April 6, 2009.
