| Thermonuclear behavior of unique neutron star captured Posted: 10 Mar 2012 12:00 PM PST A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth into a sphere no larger than a city. In October 2010, a neutron star near the center of our galaxy erupted with hundreds of X-ray bursts that were powered by a barrage of thermonuclear explosions on the star's surface. NASA captured the month-long fusillade in extreme detail.  |
| Scientists discover effects of PD-1 blockade on ART therapy in SIV-infected monkeys Posted: 08 Mar 2012 02:49 PM PST Scientists have discovered that blocking PD-1, an immune molecule that inhibits the immune response to viral infections, can have a significant effect on HIV-like illness in non-human primates.  |
| Experiment observes elusive neutrino transformation Posted: 08 Mar 2012 11:32 AM PST Physicists have detected and measured, for the first time, a transformation of one particular type of neutrino into another type. The finding, physicists say, may help solve some of the biggest mysteries about the universe, such as why the universe contains more matter than antimatter -- a phenomenon that explains why stars, planets, and people exist at all.  |
