For statues, stress injuries come from standing in place for hundreds of years. Using a novel technique, researchers have now developed a way to predict such fracturing, applying the procedure to Michelangelo's David in an analysis that proved simpler, faster and more accurate than previous methods.
A group of some 15 chimpanzees isolated in a pocket of Rwandan rain forest will have a greater range â€“ and, thus, greater chances for survival â€“ thanks to one of Africaâ€™s most ambitious forest restoration and ecological research efforts ever.
A 200-patient human trial is about to start into Oxycyte, a Teflon-like liquid that carries four times the oxygen levels of real, red blood cells to brain tissue damaged by traumatic injury. Without that continuous flow of oxygen, brain cells can die within hours.
Richard Leakey, former head of the Kenyan Wildlife Service, has announced his support of the culling of elephants in South Africa.
Brown bears from the Iberian Peninsula are not as genetically different from other brown bears in Europe as was previously thought. An international study being published this week in Proceedings of the National Academy of Sciences (PNAS) shows that, on the contrary, the Spanish bear was only recently isolated from other European strains. These findings shed new light on the discussion of how to save the population of Spanish bears.
In large-scale field trials, scientists from North Carolina State University have shown that silencing a specific gene in burley tobacco plants significantly reduces harmful carcinogens in cured tobacco leaves.
Using data from the SCIAMACHY instrument aboard ESA's Envisat environmental satellite, scientists have for the first time detected regionally elevated atmospheric carbon dioxide â€“ the most important greenhouse gas that contributes to global warming â€“ originating from manmade emissions.
Researchers at the nonprofit Cetos Research Organization have shown for the first ever that humpback whale calves make sounds.
Using the latest satellite observations, NASA researchers and others report that the Arctic is still on â€œthin iceâ€ when it comes to the condition of sea ice cover in the region.
