| Birds that live with varying weather sing more versatile songs Posted: 03 Aug 2012 10:19 AM PDT A new study of North American songbirds reveals that birds that live with fluctuating weather are more flexible singers. Mixing it up helps birds ensure that their songs are heard no matter what the habitat.  |
| Giant moa had climate change figured out Posted: 03 Aug 2012 08:44 AM PDT An international team of scientists has used ancient DNA from bones of giant extinct New Zealand birds to show that significant climate and environmental changes did not have a large impact on their populations.  |
| Researchers invent new tool to study single biological molecules Posted: 03 Aug 2012 08:08 AM PDT Researchers have developed new microscope technology to study single biological molecules with unprecedented accuracy and precision.  |
| Supernova progenitor found? New research identifies star system that may explode Posted: 03 Aug 2012 07:30 AM PDT Type Ia supernovae are violent stellar explosions. Observations of their brightness are used to determine distances in the universe and have shown scientists that the cosmos is expanding at an accelerating rate. But there is still too little known about the specifics of the processes by which these supernovae form. New research identifies a star system, prior to explosion, which will possibly become a type Ia supernova.  |
| Predatory beetles eavesdrop on ants' chemical conversations to find best egg-laying sites Posted: 03 Aug 2012 07:29 AM PDT Predatory beetles can detect the unique alarm signal released by ants that are under attack by parasitic flies, and the beetles use those overheard conversations to guide their search for safe egg-laying sites on coffee bushes.  |
| People with Allergies May Have Lower Risk of Brain Tumors Posted: 03 Aug 2012 06:44 AM PDT New research adds to the growing body of evidence suggesting that there's a link between allergies and reduced risk of a serious type of cancer that starts in the brain.  |
| Turning white fat into energy-burning brown fat: Hope for new obesity and diabetes treatments Posted: 02 Aug 2012 09:23 AM PDT Medical researchers have identified a mechanism that can give energy-storing white fat some of the beneficial characteristics of energy-burning brown fat. The findings, based on studies of mice and of human fat tissue, could lead to new strategies for treating obesity and type 2 diabetes.  |
