| Vigorous star birth without galactic collisions: Herschel paints new story of galaxy evolution Posted: 13 Sep 2011 04:55 PM PDT The European Space Agency's Herschel infrared space observatory has discovered that galaxies do not need to collide with each other to drive vigorous star birth. The finding overturns this long-held assumption and paints a more stately picture of how galaxies evolve.  |
| Double jeopardy: Building codes may underestimate risks due to multiple hazards Posted: 13 Sep 2011 02:27 PM PDT As large parts of the United States recover from nature's one-two punch -- an earthquake followed by Hurricane Irene -- building researchers warn that a double whammy of seismic and wind hazards can increase the risk of structural damage to as much as twice the level implied in building codes.  |
| Blood vessels from your printer? Posted: 13 Sep 2011 09:20 AM PDT Researchers have been working on growing tissue and organs in the laboratory for a long time. Today, tissue engineering enables us to build up artificial tissue, although science still hasn't been successful with larger organs.  |
| Star blasts planet with X-rays Posted: 13 Sep 2011 09:20 AM PDT A nearby star is pummeling a companion planet with a barrage of X-rays a hundred thousand times more intense than the Earth receives from the Sun. New data suggest that high-energy radiation is evaporating about 5 million tons of matter from the planet every second. This result gives insight into the difficult survival path for some planets.  |
| Intense magnetic fields probably formed shortly after Big Bang, researchers say Posted: 13 Sep 2011 06:08 AM PDT Intense magnetic fields were probably generated in the universe shortly after the Big Bang, according to an international team of researchers.  |
| Superconductivity: New piece in the puzzle Posted: 13 Sep 2011 06:08 AM PDT By destabilizing superconductivity with a strong magnetic field, the electrons of a "high temperature" superconductor align into linear filaments. This phenomenon has been demonstrated by a team of researchers in France. The results add a new piece to the puzzle that condensed-matter physicists have been trying to put together for nearly 25 years.  |
