| Posted: 12 Oct 2012 11:37 AM PDT Spots on the butts of fruit flies are really, really small. But what a researcher and his graduate student are discovering about them could be gigantic. Researchers have discovered that three genes that cause cancer and disease in humans also "paint" the spots on the fly's body. This discovery could enable researchers to study how those genes work in fruit flies and apply that knowledge to treating cancer in people. |
| 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. |
| 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. |
| 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. |
