Tropical deforestation is the source of nearly a fifth of annual, human-induced emissions of heat-trapping gases to the atmosphere. Recent studies by Woods Hole Research Center scientists demonstrate that during years of severe drought, tropical rainforest fires can double emissions from tropical forests. Now, an international team of forest and climate researchers has found that halving defores...UCI launches effort to develop patient-specific stem cell lines

Rosemont, Ill. January 5, 2007 The Food and Drug Administration (FDA) has proposed an amended health claim that would communicate to consumers the value of foods high in calcium and vitamin D for reducing the risk of osteoporosis. The National Dairy Council (NDC) acknowledges and supports the body of scientific evidence that backs the proposed claim, which indicates that a lifestyle that incl...'Marathon mice' elucidate little-known muscle type

... Researchers at UC Irvine have found that fat droplets -- tiny balls of fat that exist in most cells -- appear to have an intriguing role to play when it comes to regulating excess proteins in the body. In a study with fruit flies, developmental biologist Steven Gross and colleagues found that these fat droplets served as storage depots for a type of protein used primarily by the cell to bind...UCI scientists use near real-time sensor data to detect coastal ocean pollution
