| In metallic glasses, researchers find a few new atomic structures Posted: 11 May 2012 10:37 AM PDT Drawing on powerful computational tools and a state-of-the-art scanning transmission electron microscope, materials science and engineering researchers have discovered a new nanometer-scale atomic structure in solid metallic materials known as metallic glasses.  |
| Low-cost nanosheet catalyst discovered to split hydrogen from water Posted: 11 May 2012 09:22 AM PDT Scientists have developed a new electrocatalyst that overcomes the high cost of platinum, generating hydrogen gas from water with abundant and affordable metals. The unexpected and high-performing nanosheet structure of the catalytic nickel-molybdenum-nitride compound offers a promising new model for effective hydrogen catalysis.  |
| First satellite tag study for manta rays reveals habits and hidden journeys of ocean giants Posted: 11 May 2012 09:22 AM PDT Using the latest satellite tracking technology, conservationists have completed a ground-breaking study on a mysterious ocean giant: The manta ray.  |
| Newly discovered bacterium forms intracellular minerals Posted: 11 May 2012 07:13 AM PDT A new species of photosynthetic bacterium has come to light: it is able to control the formation of minerals (calcium, magnesium, barium and strontium carbonates) within its own organism. This is a new type of biomineralization, whose mechanism is still unknown. This finding has important implications for the interpretation of the ancient fossil record.  |
| How nature shapes the birth of stars Posted: 11 May 2012 07:12 AM PDT Using state of the art computer simulations, a team of astronomers have found the first evidence that the way in which stars form depends on their birth environment.  |
| An incisive design solution: The spider's venomous fang Posted: 11 May 2012 07:12 AM PDT Among the factors that make spiders successful predators is the ingeniously composed and structured material of their fangs.  |
| Asteroid Vesta looks like a little planet, complete with craters, mountains and landslides Posted: 10 May 2012 07:49 PM PDT Vesta looks like a little planet. "We didn't find gold on Vesta, but it is still a gold mine," said the principal investigator of NASA's Dawn mission. Scientists have discovered two large craters, a mountain more than twice as large as Mount Everest, and landslides, detailed in six new articles.  |
| Greater insight into earthquake cycles Posted: 10 May 2012 11:20 AM PDT For those who study earthquakes, one major challenge has been trying to understand all the physics of a fault -- both during an earthquake and at times of "rest" -- in order to know more about how a particular region may behave in the future. Now, researchers have developed the first computer model of an earthquake-producing fault segment that reproduces the available observations of both the fault's seismic and aseismic behavior.  |
| Scientists identify protein that stimulates brown fat to burn calories Posted: 10 May 2012 09:28 AM PDT Scientists have identified a protein which regulates the activation of brown fat in both the brain and the body's tissues.  |
| Potential instability in West Antarctic Ice Sheet from newly discovered basin size of New Jersey Posted: 10 May 2012 07:05 AM PDT Scientists have uncovered a previously unknown sub-glacial basin nearly the size of New Jersey beneath the West Antarctic Ice Sheet near the Weddell Sea. The location, shape and texture of the mile-deep basin suggest that this region of the ice sheet is at a much greater risk of collapse than previously thought.  |
