| Astronomers see black hole raging red Posted: 15 Mar 2016 07:04 PM PDT Violent red flashes, lasting just fractions of a second, have been observed during one of the brightest black hole outbursts in recent years. In June 2015, a black hole called V404 Cygni underwent dramatic brightening for about two weeks, as it devoured material that it had stripped off an orbiting companion star. V404 Cygni, which is about 7,800 light years from Earth, was the first definitive black hole to be identified in our Galaxy and can appear extremely bright when it is actively devouring material. Astronomers report that the black hole emitted dazzling red flashes lasting just fractions of a second, as it blasted out material that it could not swallow. |
| Storks give up on winter migration in favor of junk food Posted: 15 Mar 2016 07:02 PM PDT Storks are giving up on winter migration in favor of junk food, new research indicates.

| 400,000-year-old fossils from Spain provide earliest genetic evidence of Neanderthals Posted: 15 Mar 2016 09:09 AM PDT Previous analyses of the hominins from Sima de los Huesos in 2013 showed that their maternally inherited mitochondrial DNA was distantly related to Denisovans, extinct relatives of Neanderthals in Asia. This was unexpected since their skeletal remains carry Neanderthals-derived features. Researchers have since worked on sequencing nuclear DNA from fossils from the cave, a challenging task as the extremely old DNA is degraded to very short fragments. The results now show that the Sima de los Huesos hominins were indeed early Neanderthals. |
