Of mice, men, trees and the global carbon cycle
...synthesis, in which carbon dioxide is absorbed and stored
as plant tissue, is difficult to measure but can be estimated globally from satellites, based on the visible plant cover. The plant cover indicates how much light the plants will intercept. Even harder to calculate are the global amounts of carbon di...
Global warming - the blame is not with the plants
... 2 g methane emitted per kg of CO2 assimilated and stored
in plants for longer periods. Over a 100-year horizon, the global warming potential of methane is ~20 times higher than that of carbon dioxide. Thus, for climate, the benefits gained by reforestation programs would be lessened by between 1 and 4 per ...
Fat overload kills mammalian cells key culprit identified
...ays. "But saturated fats like palmitate are poorly stored
in the tiny fat droplets normally found in most cells and therefore are more likely to enter into pathways that lead to cell death such as the one in which EF1A-1 is involved." In the process of identifying the role of EF1A-1, the lab members uncove...
