ScienceDaily (Mar. 3, 2009) — When it comes to the hippocampus, a brain structure vital to certain types of memory, size matters. Numerous studies have shown that bigger is usually better. Now researchers have found that elderly adults who are more physically fit tend to have bigger hippocampi and better spatial memory than those who are less fit.…

ScienceDaily (Feb. 28, 2009) — HIV is evolving rapidly to escape the human immune system, an international study led by Oxford University has shown. The findings, published in Nature, demonstrate the challenge involved in developing a vaccine for HIV that keeps pace with the changing nature of the virus.…

Projection of the what the first Antarctic ice sheet might have looked like as the global climate cooled about 33.5 million years ago. Antarctica is in gray, with the ice sheet shown in meters of ice thickness. The ice sheet is continental in scale, but somewhat smaller than today. The estimate is based on prior modeling work of DeConto and Pollard and is supported by this new data study.… Posted in Science News Tags: 5 Million, Amp, Antarctic Ice Sheet, Antarctica, Carbon Dioxide, Climate Changes, Climatic Conditions, Geologists, Glacier, Global Climate, Global Cooling, Global Temperature Change, Greenhouse, Massive Ice, Million Years, New Perspective, Pollard, Science Daily, Sciencedaily, Transition One Comments Off February 26th, 2009 Malvika Sampat
