| Drawing connections between food webs: Universal truths about species' roles uncovered Posted: 04 Apr 2012 01:19 PM PDT Researchers have discovered universal truths about species' roles in food webs. The findings could open doors to increasingly global approaches in conservation.  |
| Reproductive seasonality observed in male giant pandas Posted: 04 Apr 2012 01:19 PM PDT A three-year study of giant pandas reveals that reproductive seasonality exists not only in female pandas, but in male pandas as well. According to the authors, this new understanding of the regulators of male reproductive function will allow continued improvement of the captive panda management program and will, one day, assist in reintroducing pandas into the wild.  |
| New options for nuclear waste? Crushing pressure surprisingly opens up nanopores in mineral Posted: 04 Apr 2012 11:41 AM PDT By squeezing a porous solid, scientists surprisingly made its cavities open wider, letting in -- and trapping -- europium ions. Given the similarities between europium and uranium ions, the team thinks the innovation could represent a promising new avenue for nuclear waste processing.  |
| Posted: 04 Apr 2012 10:38 AM PDT Climate scientists have proposed a simple new mechanism to explain the source of carbon that fed a series of extreme warming events about 55 million years ago, the Paleocene-Eocene Thermal Maximum, and a sequence of similar, smaller warming events afterward.  |
| Posted: 04 Apr 2012 10:37 AM PDT Three-spine sticklebacks aren't as pretty as many aquarium fish, and anglers don't fantasize about hooking one. But biologists treasure these small fish for what they are revealing about the genetic changes that drive evolution. Now, researchers have sequenced the stickleback genome for the first time, and they have discovered that as fish in different parts of the world adapted to live in fresh water, the same sites in the genome were changed time and again.  |
| Posted: 04 Apr 2012 10:37 AM PDT Research into the behavior of flies and their sleep-wake mechanism in a natural environment flies in the face of over 40 years of research in controlled laboratory conditions.  |
| Potential method to control obesity: Red wine, fruit compound could help block fat cell formation Posted: 04 Apr 2012 09:53 AM PDT A compound found in red wine, grapes and other fruits, and similar in structure to resveratrol, is able to block cellular processes that allow fat cells to develop, opening a door to a potential method to control obesity, according to a new study.  |
| Some 'improved cookstoves' may emit more pollution than traditional mud cookstoves Posted: 04 Apr 2012 09:53 AM PDT The first real-world, head-to-head comparison of "improved cookstoves" (ICs) and traditional mud stoves has found that some ICs may at times emit more of the worrisome "black carbon," or soot, particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires. The report raises concerns about the leading hope as a clean cooking technology in the developing world.  |
| Defying conventional wisdom, water can float on oil Posted: 04 Apr 2012 09:52 AM PDT Defying thousands of years of conventional wisdom, scientists are reporting that it is possible for water to float on oil, a discovery they say has important potential applications in cleaning up oil spills that threaten seashores and fisheries.  |
| How social contact with sick ants protects their nestmates Posted: 04 Apr 2012 07:23 AM PDT Micro-infections have been found to promote social vaccination in ant societies. Like crowded megacities, ant colonies face a high risk of disease outbreaks. These are kept in check by the ants' "social immune system"— a set of collective hygienic behaviors and adaptive changes in interaction frequencies that acts in conjunction with the physiological, innate immune system of colony members.  |
| Vegetation cover affects the speed of snowmelt in tundra regions Posted: 04 Apr 2012 07:22 AM PDT Climate change has increased vegetation in Arctic tundra regions. According to a recent study, the increase in vegetation in tundra regions may further accelerate global warming.  |
