...hroughout most of the Antarctic winter season. The longest track was 326 days and up to 30,000 profiles of temperature and salinity were obtained. By simultaneously recording movements, dive behaviour and oceanographic conditions, the new sensors allow researchers to examine in detail how elephant seals re...Study identifies energy efficiency as reason for evolution of upright walking
...ctive muscle mass. Indeed, the chimpanzee with the longest stride was the most efficient walking upright. What those results allowed us to do was to look at the fossil record and see whether fossil hominins show adaptations that would have reduced bipedal energy expenditures, said Raichlen.

Other paleoclimatic research had suggested that epic droughts occurred in much of the western U.S. during the Medieval Climate Anomaly of about 900 to 1300, a time when some parts of the world were warmer than now.

... PLoS Biology. The study is one of the largest and longest surveys of ocean temperature and coral disease and is the first to conclusively demonstrate a link between disease severity and ocean temperature, Bruno said. The colorful coral colonies that attract visitors to the Great Barrier Reef live atop a ...... He found that the smallest bees sometimes had the longest tongues and the largest bees sometimes had the shortest tongues. But after taking into account all that variation in body size, he says long tongues really do impose a mechanical cost on bees. Everyone knows just how busy bees can be, but orchid bees...Ancient coral reef tells the history of Kenya's soil erosion
