| Some corals like it hot: Heat stress may help coral reefs survive climate change Posted: 30 Mar 2012 05:59 PM PDT Scientists working in the central Pacific have discovered that coral which has survived heat stress in the past is more likely to survive it in the future. The study paves the way towards an important road map on the impacts of ocean warming, and will help scientists identify the habitats and locations where coral reefs are more likely to adapt to climate change. |
| Organics probably formed easily in early solar system Posted: 30 Mar 2012 05:58 PM PDT Complex organic compounds, including many important to life on Earth, were readily produced under conditions that likely prevailed in the primordial solar system. Scientists came to this conclusion after linking computer simulations to laboratory experiments. |
| Images capture split personality of dense suspensions Posted: 30 Mar 2012 01:49 PM PDT Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior momentarily reveals a decidedly non-viscous side. Physicists have recorded this surprising behavior in laboratory experiments using high-speed photography that can capture action taking place in one hundred-thousandths of a second or less. |
| Honeycombs of magnets could lead to new type of computer processing Posted: 30 Mar 2012 09:32 AM PDT Scientists take an important step in developing a material using nano-sized magnets that could lead to new electronic devices. Researchers have demonstrated that large arrays of nano-magnets can be used to store computable information. |
| Bees 'self-medicate' when infected with some pathogens Posted: 30 Mar 2012 08:10 AM PDT Honey bees "self-medicate" when their colony is infected with a harmful fungus, bringing in increased amounts of antifungal plant resins to ward off the pathogen. |
| Posted: 30 Mar 2012 08:10 AM PDT Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to predicting large eruptions. International teams of researchers studied the location and behavior of magma chambers on Earth's mid-ocean ridge system -- a vast chain of volcanoes along which Earth forms new crust. |
| Crocodiles trump T. rex as heavyweight bite-force champions, new study shows Posted: 30 Mar 2012 08:02 AM PDT Biologists have found in a study of all 23 living crocodilian species that crocodiles can kill with the strongest bite force measured for any living animal. The study also revealed that the bite forces of the largest extinct crocodilians exceeded 23,000 pounds, a force two-times greater than the mighty Tyrannosaurus rex. |
| Clocking an accelerating universe: First results from BOSS Posted: 30 Mar 2012 05:18 AM PDT First spectroscopic results from BOSS give the most detailed look yet at the time when dark energy turned on some six billion light years ago, as the expansion of the universe was slipping from the grasp of matter's mutual gravitational attraction, and expansion began to accelerate. |
