| Chemists gain edge in next-gen energy: Flexible film can catalyze production of hydrogen Posted: 04 Nov 2014 05:38 AM PST Scientists have created a flexible film with the ability to catalyze the production of hydrogen or be used for energy storage. They have turned molybdenum disulfide's two-dimensional form into a nanoporous film that can catalyze the production of hydrogen or be used for energy storage.       |
| Posted: 03 Nov 2014 04:21 PM PST The mystery about a thin, bizarre object in the center of the Milky Way that some astronomers believe to be a hydrogen gas cloud headed toward our galaxy's enormous black hole has been solved by astronomers.  |
| How a giant impact formed asteroid Vesta's 'belt' Posted: 03 Nov 2014 01:19 PM PST Collisions of heavenly bodies generate almost unimaginable levels of energy. Researchers used NASA's ultra-high-speed cannon and computer models to simulate such a collision on Vesta, the second-largest object in the asteroid belt. Their analysis of the images -- taken at a million frames per second -- shows how Vesta may have gotten the deep grooves that encircle its midsection.  |
| Arctic warming: Scientists identify new driver Posted: 03 Nov 2014 01:19 PM PST A mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice has been identified by scientists. They found that open oceans are much less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum, a previously unknown phenomenon that is likely contributing to the warming of the polar climate.  |
| Posted: 03 Nov 2014 01:19 PM PST Yeast geneticists report they have developed a novel tool -- dubbed 'the telomerator' -- that could redefine the limits of synthetic biology and advance how successfully living things can be engineered or constructed in the laboratory based on an organism's genetic, chemical base-pair structure.  |
| Investigating a triple star system in formation Posted: 03 Nov 2014 09:10 AM PST Astronomers have carried out the most accurate study so far of the cocoon of gas and dust surrounding the GG Tau A system. By combining complementary observations at submillimeter (ALMA and IRAM) wavelengths with those at infrared (VLTI/ESO) wavelengths, the researchers were able to identify the complex dynamics at work in GG Tau. For the first time, they detected motion of matter showing that exoplanets can form not only around one of the members of this trio of young stars, but also much further out in the disc surrounding the three stars.  |
