| NASA mission returns first video from moon's far side Posted: 01 Feb 2012 03:21 PM PST A camera aboard one of NASA's twin Gravity Recovery And Interior Laboratory (GRAIL) lunar spacecraft has returned its first unique view of the far side of the moon. MoonKAM, or Moon Knowledge Acquired by Middle school students, will be used by students nationwide to select lunar images for study.  |
| Powering pacemakers with heartbeat vibrations Posted: 01 Feb 2012 03:14 PM PST Aerospace engineers have developed a prototype device that could power a pacemaker using a source that is surprisingly close to the heart of the matter: vibrations in the chest cavity that are due mainly to heartbeats.  |
| Self-assembling nanorods: Researchers obtain 1-, 2- and 3-D nanorod arrays and networks Posted: 01 Feb 2012 11:24 AM PST Researchers have developed a relatively fast, easy and inexpensive technique for inducing nanorods to self-assemble into aligned and ordered macroscopic structures. This technique should enable more effective use of nanorods in solar cells, magnetic storage devices and sensors, and boost the electrical and mechanical properties of nanorod-polymer composites.  |
| Sun delivered curveball of powerful radiation at Earth Posted: 01 Feb 2012 11:24 AM PST A potent follow-up solar flare, which occurred Jan. 17, 2012, just days after the Sun launched the biggest coronal mass ejection seen in nearly a decade, delivered a powerful radiation punch to Earth's magnetic field despite the fact that it was aimed away from our planet.  |
| Nano-oils keep the electronic devices really cool Posted: 01 Feb 2012 11:00 AM PST Scientists have created a nano-infused oil that could greatly enhance the ability of devices as large as electrical transformers and as small as microelectronic components to shed excess heat.  |
| Scientists help define structure of exoplanets Posted: 01 Feb 2012 11:00 AM PST Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. Astronomers have come up with new methods for deriving and testing the equation of state of matter in exoplanets and figured out the mass-radius and mass-pressure relations for materials relevant to planetary interiors.  |
| Scientists confirm first 'frequency comb' to probe ultraviolet wavelengths Posted: 01 Feb 2012 11:00 AM PST Physicists have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers in wavelength. Laser-generated frequency combs are the most accurate method available for precisely measuring frequencies, or colors, of light. The new tool can aid in the development of "nuclear clocks" based on ticks in the nuclei of atoms, and measurements of previously unexplored behavior in atoms and molecules.  |
| Stellar nursery: A pocket of star formation Posted: 01 Feb 2012 06:43 AM PST A new view shows a stellar nursery called NGC 3324. It was taken using the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. The intense ultraviolet radiation from several of NGC 3324's hot young stars causes the gas cloud to glow with rich colors and has carved out a cavity in the surrounding gas and dust.  |
| Self-guided bullet prototype can hit target a mile away Posted: 30 Jan 2012 02:02 PM PST A new design for a self-guided bullet could help war fighters, scientists report. Researchers have invented a dart-like, self-guided bullet for small-caliber, smooth-bore firearms that could hit laser-designated targets at distances of more than a mile (about 2,000 meters).  |
