Outliving the Ice Age: Tale of a Rhinoceros (ScienceDaily) >
Species extinction is a fundamental part of evolution: the best adapted species survives, while others die out. A new study shows why, after 800,000 years of successful survival, a species of rhinoceros suddenly disappeared.
Sharper than Hubble: Large Binocular Telescope achieves major breakthrough (PhysOrg)
The next generation of adaptive optics has arrived at the Large Binocular Telescope (LBT) in Arizona, providing astronomers with a new level of image sharpness never before seen. Developed in a collaboration between Italy`s Arcetri Observatory of the Istituto Nazionale di Astrofisica (INAF) and the University of Arizona`s Steward Observatory, this technology represents a remarkable step forward for astronomy.
Insomniacs have different brains, researcher says (ScienceDaily)
The brains of older adults with chronic sleep problems look different from those of adults who have enjoyed enough sleep. Yet the older adults function well despite their lack of sleep. They switch to a continuous form of mild stress, as a result of which they sometimes even perform better than contemporaries who enjoy a good night’s sleep, according to a Dutch researcher.
Experience shapes the brain’s circuitry throughout adulthood (EurekAlert!)
The adult brain, long considered to be fixed in its wiring, is in fact remarkably dynamic. Neuroscientists once thought that the brain’s wiring was fixed early in life, during a critical period beyond which changes were impossible. Recent discoveries have challenged that view, and now, research by scientists at Rockefeller University suggests that circuits in the adult brain are continually modified by experience.
Massive black holes ‘switched on’ by galaxy collision (PhysOrg)
The centre of most galaxies harbours a massive black hole. Our Milky Way galaxy is one of these – the exotic object there however is reasonably calm, unlike some super-massive gravity monsters in other galaxies. Scientists at the Max Planck Institute for Extraterrestrial Physics and other institutions around the world have now analysed 199 of these galaxies and discovered what makes the black holes at the galaxy centres become active: The black holes were “switched on” some 700 million years ago after major galaxy merger events.
