| Posted: 19 Jun 2013 04:52 PM PDT A sliver of wood coated with tin could make a tiny, long-lasting, efficient and environmentally friendly battery, say scientists. |
| Carbon nanotube harpoon catches individual brain-cell signals Posted: 19 Jun 2013 04:51 PM PDT Neuroscientists may soon be modern-day harpooners, snaring individual brain-cell signals instead of whales with tiny spears made of carbon nanotubes. |
| Metamorphosis of moon's water ice explained Posted: 19 Jun 2013 01:47 PM PDT Using data gathered by NASA's Lunar Reconnaissance Orbiter mission, scientists believe they have solved a mystery from one of the solar system's coldest regions -- a permanently shadowed crater on the moon. They have explained how energetic particles penetrating lunar soil can create molecular hydrogen from water ice. The finding provides insight into how radiation can change the chemistry of water ice throughout the solar system. |
| New microfluidic chip can help identify unwanted particles in water and food Posted: 19 Jun 2013 01:43 PM PDT Researchers have developed a new microfabrication technique to develop three-dimensional microfluidic devices in polymers. The devices can be used in the analysis of cells and could prove useful in counterterrorism measures and in water and food safety concerns. |
| Simple and inexpensive process to make a material for CO2 adsorption Posted: 19 Jun 2013 01:15 PM PDT Researchers have developed a novel, simple method to synthesize hierarchically nanoporous frameworks of nanocrystalline metal oxides such as magnesia and ceria by the thermal conversion of well-designed metal-organic frameworks (MOFs). |
| Posted: 19 Jun 2013 10:24 AM PDT A practical new approach to holographic video could also enable 2-D displays with higher resolution and lower power consumption. |
| Milestone for quantum networks: First entanglement between light and an optical atomic coherence Posted: 19 Jun 2013 10:24 AM PDT Using clouds of ultra-cold atoms and a pair of lasers operating at optical wavelengths, researchers have reached a quantum network milestone: entangling light with an optical atomic coherence composed of interacting atoms in two different states. |
| Mars had oxygen-rich atmosphere 4,000 million years ago Posted: 19 Jun 2013 10:24 AM PDT Differences between Martian meteorites and rocks examined by a NASA rover can be explained if Mars had an oxygen-rich atmosphere 4,000 million years ago -- well before the rise of atmospheric oxygen on Earth 2,500 million years ago. |
| Unusual supernova is doubly unusual for being perfectly normal Posted: 19 Jun 2013 09:21 AM PDT Type Ia supernovae are indispensable milestones for measuring the expansion of the universe. With definitive measures of Supernova 2011fe, the "Backyard Supernova" that thrilled amateur and professional astronomers alike in the summer of 2011, the Nearby Supernova Factory demonstrates that this unusually close-by Type Ia is such a perfect example of its kind that future Type Ia's -- and models meant to explain their physics -- must be measured against it. |
| Sound waves precisely position nanowires Posted: 19 Jun 2013 07:28 AM PDT The smaller components become, the more difficult it is to create patterns in an economical and reproducible way, according to an interdisciplinary team of researchers who, using sound waves, can place nanowires in repeatable patterns for potential use in a variety of sensors, optoelectronics and nanoscale circuits. |
| Three centaurs follow Uranus through the solar system Posted: 18 Jun 2013 07:16 AM PDT Astrophysicists have confirmed that Crantor, a large asteroid with a diameter of 70 km has an orbit similar to that of Uranus and takes the same amount of time to orbit the Sun. Researchers have demonstrated for the first time that this and a further two objects of the group of the Centaurs are co-orbital with Uranus. |
