| 'Lost world' discovered around Antarctic vents Posted: 03 Jan 2012 03:52 PM PST Communities of species previously unknown to science have been discovered on the seafloor near Antarctica, clustered in the hot, dark environment surrounding hydrothermal vents. The discoveries include new species of yeti crab, starfish, barnacles, sea anemones, and potentially an octopus. |
| A shot of young stem cells made rapidly aging mice live much longer and healthier Posted: 03 Jan 2012 10:51 AM PST Mice bred to age too quickly seemed to have sipped from the fountain of youth after scientists injected them with stem cell-like progenitor cells derived from the muscle of young, healthy animals. Instead of becoming infirm and dying early as untreated mice did, animals that got the stem/progenitor cells improved their health and lived two to three times longer than expected. |
| Posted: 29 Dec 2011 06:16 AM PST Chimpanzees, orangutans, gorillas and bonobos make more sophisticated decisions than was previously thought. Great apes weigh their chances of success, based on what they know and the likelihood to succeed when guessing, according to a new study. The findings may provide insight into human decision-making as well. |
| Members of small monkey groups more likely to fight for their group Posted: 27 Dec 2011 06:07 PM PST Small monkey groups may win territorial disputes against larger groups because some members of larger, invading groups avoid aggressive encounters. Scientists show that individual monkeys that don't participate in conflicts prevent large groups from achieving their competitive potential. |
