Antipater writes "To the brain, heartbreak and emotional torment are no different from having hot coffee spilled on your hand, reports CNN. They cite a recent study from Proceedings of the National Academy of Sciences in which 40 recently-dumped men and women underwent fMRI scans while having their ar
An anonymous reader writes "Vladimir Romanov has released what he claims is a polynomial-time algorithm for solving 3-SAT. Because 3-SAT is NP-complete, this would imply that P==NP. While there's still good reason to be skeptical that this is, in fact, true, he's made source code available and appears decidedly more serious than most of the people attempting to prove that P==NP or P!=NP. Even thou

However, the virus will likely evolve around these drugs, making it crucially important to get a better understanding of the virus itself. An important step in understanding the virus is to get a handle on its genetic blue

Posted by timothy on Wednesday August 26, 2009 @03:36PM from the to-be-aware-of dept. natehoy writes "According to the US News and World Report, a recent study has shown a link between obesity and the loss of neurological tissue. The brains of elderly patients who were obese had on average 8% less tissue than their trimmer counterparts. Overweight patients had brains lighter by about 4%. This coul
Al writes "A woman with a rare, inherited form of blindness is now able to read, thanks to a gene therapy that caused a new fovea — the part of the retina that is most densely populated with photoreceptors — to grow in her eye. The patient suffers from Leber congenital amaurosis, meaning an abnormal protein makes her photoreceptors have a severely impaired sensitivity to light. She received the ex

Adam Korbitz writes "New Scientist is reporting the extrasolar planet MOA-2007-BLG-192Lb — whose discovery was announced just last summer — may actually be the first truly Earth-sized exoplanet to be identified. A new analysis suggests the planet weighs less than half the original estimate of 3.3 Earth masses; the new estimate pegs the planet's size at 1.4 Earth masses. The planet orbits a small r

KentuckyFC writes "A scrambled Rubik's cube can be solved in just 25 moves, regardless of the starting configuration. Tomas Rokicki, a Stanford-trained mathematician, has proven the new limit (down from 26 which was proved last year) using a neat piece of computer science. Rather than study individu
Tech.Luver writes "Gene Expression reports, "Tyler Cowen quotes from a new study testing the relationship between grades and delayed sexual activity. Last December I passed a paper along to Razib showing that high-school age adolescents with higher IQs and extremely low IQs were less likely to have had first intercourse than those with average to below average intelligence.
