| NASA's Ironman-like exoskeleton could give astronauts, paraplegics improved mobility and strength Posted: 12 Oct 2012 11:19 AM PDT Marvel Comic's fictional superhero, Ironman, uses a powered armor suit that allows him superhuman strength. While NASA's X1 robotic exoskeleton can't do what you see in the movies, the latest robotic, space technology, spinoff derived from NASA's Robonaut 2 project may someday help astronauts stay healthier in space with the added benefit of assisting paraplegics in walking here on Earth. |
| Posted: 12 Oct 2012 09:26 AM PDT A new approach that allows objects to become "invisible" has now been applied to an entirely different area: letting particles "hide" from passing electrons, which could lead to more efficient thermoelectric devices and new kinds of electronics. |
| The worst noises in the world: Why we recoil at unpleasant sounds Posted: 12 Oct 2012 08:24 AM PDT Heightened activity between the emotional and auditory parts of the brain explains why the sound of chalk on a blackboard or a knife on a bottle is so unpleasant. |
| X-raying stellar winds in a high-speed collision Posted: 12 Oct 2012 08:21 AM PDT Two massive stars racing in orbit around each other have had their colliding stellar winds X-rayed for the first time, thanks to the combined efforts of the European Space Agency's XMM-Newton and NASA's Swift space telescopes. |
| Fly genomes show natural selection and return to Africa Posted: 12 Oct 2012 07:26 AM PDT New studies of the genomes of almost 200 strains of Drosophila flies show natural selection and a "return to Africa" of the tiny flies, which likely migrated with ancestral humans tens of thousands of years ago. |
| Transplantation of embryonic neurons raises hope for treating brain diseases Posted: 12 Oct 2012 07:21 AM PDT The unexpected survival of embryonic neurons transplanted into the brains of newborn mice in a series of experiments raises hope for the possibility of using neuronal transplantation to treat diseases like Alzheimer's, epilepsy, Huntington's, Parkinson's and schizophrenia. |
| When galaxies eat galaxies: Gravity lenses suggest big collisions make galaxies denser Posted: 12 Oct 2012 05:21 AM PDT Using gravitational "lenses" in space, astronomers have discovered that the centers of the biggest galaxies are growing denser -- evidence of repeated collisions and mergers by massive galaxies with 100 billion stars. |
| Scientists identify trigger for explosive volcanic eruptions Posted: 12 Oct 2012 04:47 AM PDT Scientists have identified a repeating trigger for the largest explosive volcanic eruptions on Earth. The Las Cañadas volcanic caldera on Tenerife, in the Canary Islands, has generated at least eight major eruptions during the last 700,000 years. These catastrophic events have resulted in eruption columns of over 25km high and expelled widespread pyroclastic material over 130km. By comparison, even the smallest of these eruptions expelled over 25 times more material than the 2010 eruption of Eyjafjallajökull, Iceland. |
