| 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. |
| 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. |
| 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. |
| Posted: 12 Oct 2012 04:48 AM PDT Researchers have discovered how to control the shape of nanoparticles that move DNA through the body and have shown that the shapes of these carriers may make a big difference in how well they work in treating cancer and other diseases. This study is also noteworthy because this gene therapy technique does not use a virus to carry DNA into cells. |
