Behind the mask of the LHC
British Journal of Pharmacology (Free subscription) | yesterday
The physics that the Large Hadron Collider will explore has tentative philosophical foundations. But that#25;s a good thing, says Philip Ball.

Interview With Atle Selberg
Not Even Wrong (Free subscription) | 1 hour ago
Sticking with the theme of the Riemann Hypothesis, the AMS has recently posted some articles to appear in an upcoming issue of the AMS Bulletin, one of which contains a long interview with Atle Selberg, who died last summer at the age of 90. Selberg had been a professor at the IAS and an [...]

Phoenix To Bake Ice-Rich Sample Next Week
Science Daily (Free subscription) | 03/07/2008
The next sample delivered to NASA's Phoenix Mars Lander's Thermal and Evolved-Gas Analyzer (TEGA) will be ice-rich. A team of engineers and scientists assembled to assess TEGA after a short circuit was discovered in the instrument has concluded that another short circuit could occur when the oven is used again.

Mining For Molecules In The Milky Way
Science Daily (Free subscription) | 03/07/2008
Scientists are prospecting in a rich molecular cloud in our Milky Way Galaxy. They seek to discover new, complex molecules in interstellar space that may be precursors to life. As molecules rotate and vibrate, they emit radio waves at specific frequencies. Each molecule has a unique pattern of such frequencies, called spectral lines, that constitutes a "fingerprint" identifying that molecule. Laboratory...

Proof of the Riemann Hypothesis?
Not Even Wrong (Free subscription) | 02/07/2008
Last night a preprint by Xian-Jin Li appeared on the arXiv, claiming a proof of the Riemann Hypothesis. Preprints claiming such a proof have been pretty common, and always wrong. Most of them are obviously implausible, invoking a few pages of elementary mathematics and authored by people with no track record of doing [...]

Exploding Asteroid Theory Strengthened By New Evidence Located In Ohio, Indiana
Science Daily (Free subscription) | 02/07/2008
Was the course of life on the planet altered 12,900 years ago by a giant comet exploding over Canada? New evidence suggests the answer is affirmative. The timing attached to this theory of about 12,900 years ago is consistent with the known disappearances in North America of the wooly mammoth population and the first distinct human society to inhabit the continent, known as the Clovis civilization....

Improving Diagnosis Of Osteoporosis: Computer Simulations Help Predict Fracture Risk
Science Daily (Free subscription) | 02/07/2008
Using a Blue Gene supercomputer, scientists have demonstrated the most extensive simulation yet of actual human bone structure. This achievement may lead to better clinical tools to improve the diagnosis and treatment of osteoporosis, a widespread disease that worldwide affects one in three women and one in five men over the age of 50.

Healthy Or Diseased? Analysis Of Body's Metabolism Sheds New Light On The Question
Science Daily (Free subscription) | 02/07/2008
Scientists have shown that biological indicators for diseases caused or influenced by environmental factors can be detected by the systemic analysis of the body's metabolism (metabolomics). The procedure presented here is also suitable for pre-clinical drug testing and allows for the early detection of possible side effects of a new medication.

Species Extinction Threat Underestimated Due To Math Glitch
Science Daily (Free subscription) | 02/07/2008
Extinction risks for natural populations of endangered species are likely being underestimated by as much as 100-fold because of a mathematical "misdiagnosis," according to a new study. Researchers have noted that sex ratio variations and physical variation between individuals within a population -- have been ignored or mischaracterized by most extinction risk modelers.

First Images Of Solar System's Invisible Frontier
Science Daily (Free subscription) | 02/07/2008
An instrument aboard NASA's STEREO spacecraft unexpectedly detected particles from the edge of the solar system last year, allowing UC Berkeley scientists to map for the first time the energized particles in the region where the hot solar wind slams into the cold interstellar medium. The region, at about 100 AU, is invisible to other telescopes, but can be mapped by detecting energetic neutral atoms,...

Universal emission intermittency in quantum dots, nanorods and nanowires
Nature (Free subscription) | 01/07/2008
Fluorophores are quantum objects that blink intermittently and whose dark states exist practically ‘forever’—on quantum-mechanical scales, that is. Although there is no accepted theory, there has been plenty of theoretical progress.
