The 2011 Nobel Prize in Physics goes to Saul Perlmutter at the Lawrence Berkeley National Lab, Brian Schmidt at the Australian National Lab and Adam Reiss at Johns Hopkins. The Royal Swedish Academy’s Olga Botner: “In a universe which is dominated by matter, one would expect gravity eventually should make the expansion slow down.

(PhysOrg.com) -- Neutrons, the particles that along with protons, exist in the nuclei of atoms (except for hydrogen) have been intensely studied ever since their discovery in the 1930’s. And while many interesting developments have occurred as a result (fission reactions, etc) physicists have continued to be frustrated in their attempts to get a closer look at them, due to their not having an electric charge which could be used to hold them in place.

(PhysOrg.com) -- Deep within a silver and lean mine in Naica, Mexico, scientists discovered what is now known as Cueva de los Cristales, or Cave of Crystals, close to a decade ago. The gypsum crystals found in this cave measure as long as 11 meters (36 feet) and as thick as 1 meter (3 feet). While these crystals are beautiful and reminiscent of a Superman film, they have had scientists stumped since their discovery

The protein encoded by the tumour-suppressor gene BRCA1 may keep breast and ovarian cancer in check by preventing transcription of repetitive DNA sequences, says a study published today in Nature . This explanation brings together many disparate theories about how the gene functions and could also shed light on how other tumour suppressors work

(PhysOrg.com) -- An incredibly rare sub-atomic particle decay might not be quite as rare as previously predicted, say Cornell researchers. This discovery, culled from a vast data set at the Collider Detector at Fermilab (CDF), is a clue for physicists trying to catch glimpses of how the universe began.

The existence of an intermediate-spin (IS) state in cobalt oxides has long been a subject of dispute.

Around a black hole 12 billion light years away, there's an almost unimaginable vapor cloud of water--enough to supply an entire planet's worth of water for every person on earth, 20,000 times over.

Let me be clear: Another Earth , opening July 22, is not a science-fiction film, despite its premise of the discovery of a planet just like our own.

(PhysOrg.com) -- Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced the observation of a new particle, the neutral Xi-sub-b (Ξb0). This particle contains three quarks: a strange quark, an up quark and a bottom quark (s-u-b). While its existence was predicted by the Standard Model, the observation of the neutral Xi-sub-b is significant because it strengthens our understanding of how quarks form matter

(PhysOrg.com) -- A high-temperature superconductor can now be switched on and off within a trillionth of a second – 100 years after the discovery of superconductivity and 25 years after the first high-temperature superconductor was. A team including physicists from the University of Oxford and the Max Planck Research Group for Structural Dynamics at the University of Hamburg has realised an ultrafast superconducting switch by using intense terahertz pulses.

(PhysOrg.com) -- Working out of Tokyo University, scientists in the Department of Materials Science, have developed a new metal alloy that unlike other “superelastic” alloys can resume its original shape in temperatures ranging from -196 to 249 degrees Celsius. Prior to this discovery, such alloys were only able to revert to their original form in the much narrower range of -20 to 80 degrees Celsius.

LINDAU, Germany--There's a magazine ad for an expensive skin care product marketed by Christian Dior that claims to trade on aquaporins, the discovery of which by Peter Agre won him the Nobel Prize in chemistry in 2003 (he shared it with Roderick MacKinnon).

Harold Kroto won the Nobel Prize in chemistry in 1996 for the discovery of buckminsterfullerene, the soccer ball shaped form of carbon better known as buckyballs. On June 28, he spoke to students [at the Lindau Nobel Laureates meeting] about science as a philosophical construct: "I'm going to talk about what science is because it's a totally misunderstood sort of subject
