| Nearby massive star explosion 30 million years ago equaled detonation of 100 million suns Posted: 26 Apr 2016 11:49 AM PDT A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, say astrophysicists. The massive explosion, Supernova 2013ej, was one of the closest to Earth in recent years. Comprehensive analysis of the exploding star's light curve and color spectrum found its sudden blast hurled material outward at 10,000 kilometers a second. |
| Despite their small brains, ravens and crows may be just as clever as chimps, research suggests Posted: 26 Apr 2016 07:15 AM PDT A new study suggests that ravens can be as clever as chimpanzees, despite having much smaller brains, indicating that rather than the size of the brain, the neuronal density and the structure of the birds' brains play an important role in terms of their intelligence. |
| Robots may be able to lift, drive, and chat, but are they safe and trustworthy? Posted: 26 Apr 2016 06:24 AM PDT Automation experts conclude that the time is ripe for human factors researchers to contribute scientific insights that can tackle the many challenges of human-robot interaction. |
| Immuno-psychiatry: When your body makes its own 'angel dust' Posted: 26 Apr 2016 06:19 AM PDT A new study reports structural brain damage from an autoimmune encephalitis that impairs behavior in ways that are somewhat similar to the effects of "angel dust". The body sometimes makes substances that have effects on the brain in ways that resemble the effects of illicit drugs. |
