| Bacteria use chat to play the 'prisoner's dilemma' game in deciding their fate Posted: 27 Mar 2012 06:57 PM PDT When faced with life-or-death situations, bacteria -- and maybe even human cells -- use an extremely sophisticated version of "game theory" to consider their options and decide upon the best course of action. Scientists said microbes "play" a version of the classic "Prisoner's Dilemma" game. |
| Posted: 27 Mar 2012 06:55 PM PDT Though Tsimane men have a third less baseline testosterone compared with U.S. men, Tsimane show the same increase in testosterone following a soccer game, suggesting that competition-linked bursts of testosterone are a fundamental aspect of human biology. |
| Elusive Bururi long-fingered frog found after 62 years Posted: 27 Mar 2012 12:28 PM PDT Herpetologists have discovered a single specimen of the Bururi long-fingered frog during a research expedition to Burundi in December 2011. The frog was last seen by scientists in 1949 and was feared to be extinct after decades of turmoil in the tiny East African nation. |
| Placenta on toast? Could we derive benefits from ingesting afterbirth? Posted: 27 Mar 2012 12:28 PM PDT Almost all non-human mammals eat placenta for good reasons. Are we missing something? Neuroscientists now suggest that ingesting components of afterbirth or placenta -- placentophagia -- may offer benefits to human mothers and perhaps to non-mothers and males. |
| Posted: 27 Mar 2012 09:48 AM PDT Researchers have created a gut-on-a-chip microdevice lined by living human cells that mimics the structure, physiology, and mechanics of the human intestine -- even supporting the growth of living microbes within its luminal space. As a more accurate alternative to conventional cell culture and animal models, the microdevice could help researchers gain new insights into intestinal disorders and evaluate the safety and efficacy of potential treatments. |
| New plastics 'bleed' when cut or scratched -- and then heal like human skin Posted: 27 Mar 2012 06:12 AM PDT A new genre of plastics that mimic the human skin's ability to heal scratches and cuts offers the promise of endowing cell phones, laptops, cars and other products with self-repairing surfaces, scientists have reported. The plastics change color to warn of wounds and heal themselves when exposed to light. |
| Some scum: Microbe in pond scum enlisted in new cancer test Posted: 26 Mar 2012 08:25 AM PDT Scientists are enlisting the living, self-propelled microbes found in pond scum — the pea-green surface slicks that form on ponds — in the development of a long-awaited new test to detect the cells that spread cancer through the bloodstream from the original tumor to new sites in the body. |
