| Galaxies are the ultimate recyclers, NASA's Hubble confirms Posted: 17 Nov 2011 05:29 PM PST New observations by NASA's Hubble Space Telescope are expanding astronomers' understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy elements. This process allows galaxies to build successive generations of stars stretching over billions of years.  |
| World's lightest material is a metal 100 times lighter than styrofoam Posted: 17 Nov 2011 12:46 PM PST Engineers have developed the world's lightest material -- with a density of 0.9 mg/cc -- about 100 times lighter than Styrofoam.  |
| Birth of black hole: Longstanding mysteries about object called Cygnus X-1 unravelled Posted: 17 Nov 2011 11:40 AM PST A precise distance measurement by the Very Long Baseline Array (VLBA) allowed astronomers to accurately calculate the mass and spin of a famous black hole, thus providing a complete description of the object.  |
| Smart swarms of bacteria inspire robotics: Adaptable decision-making found in bacteria communities Posted: 17 Nov 2011 11:40 AM PST Scientists have now discovered how bacteria collectively gather information to learn about their environment and find an optimal path to growth. This research will allow scientists to design a new generation of "smart robots" that can form intelligent swarms and aid in the development of medical micro-robots used to treat diseases in the human body.  |
| Research cracks puzzle of enzyme critical to food supply Posted: 17 Nov 2011 11:40 AM PST Researchers used the Stanford Synchrotron Radiation Lightsource at SLAC National Accelerator Laboratory to identify a key atom inside the part of the nitrogenase enzyme where atmospheric nitrogen is converted into a form that living things can use.  |
| Microfabrication breakthrough could set piezoelectric material applications in motion Posted: 17 Nov 2011 11:39 AM PST Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.  |
| Posted: 17 Nov 2011 05:13 AM PST In order to find the chemical properties of super-heavy elements, chemists must conduct one of the world's most demanding chemical experiments in a matter of seconds.  |
| Racing to be the first to create the world's heaviest element Posted: 17 Nov 2011 05:13 AM PST All heavy elements are created in gigantic supernova explosions. Now scientists are competing to create the world's heaviest element in a laboratory. Production time: less than one atom per month. Lifetime: a few modest microseconds.  |
| Posted: 17 Nov 2011 05:13 AM PST Flies are real flight artists, although they only have small wings compared to their body size. Scientists have recently identified the genetic switch that regulates the formation of flight muscles.  |
