| Tiny amounts of alcohol dramatically extend a worm's life, but why? Posted: 20 Jan 2012 03:45 PM PST Minuscule amounts of ethanol can at least double the life span of a tiny worm used as a model for aging studies, biochemists report. "This finding floored us; it's shocking" said the senior author of the study. |
| Researchers solve questions about Ethiopians' high-altitude adaptations Posted: 20 Jan 2012 03:45 PM PST Over many generations, people living in the high-altitude regions of the Andes or on the Tibetan Plateau have adapted to life in low-oxygen conditions, but exactly how their genes convey a survival advantage remains an open question. Now, scientists have made new inroads to answering this question with the first genome-wide study of high-altitude adaptations within the third major population to possess them: the Amhara people of the Ethiopian Highlands. |
| Carbon dioxide is 'driving fish crazy' Posted: 20 Jan 2012 03:42 PM PST Rising human carbon dioxide emissions may be affecting the brains and central nervous system of sea fishes with serious consequences for their survival, an international scientific team has found. Carbon dioxide concentrations predicted to occur in the ocean by the end of this century will interfere with fishes' ability to hear, smell, turn and evade predators, says a professor. |
| Dung beetle dance provides crucial orientation cues Posted: 19 Jan 2012 07:15 AM PST Dung beetle dance provides crucial orientation cues: Beetles climb on top of ball, rotate to get their bearings to maintain straight trajectory. |
