...when they die and decay they release it back into the air. Wetlands and rice paddies serve a similarly dual role for both CO2 and methane, acting as sources and sinks simultaneously. The challenge has been trying to tease out how those two functions balance out, but a new paper in the Jan. 14 issue of Science has provided some hard numbers. Using satellite data, investigators determined that wetlands contribute from 53% to 58% of global methane emissions and that rice paddies are responsible for more than a quarter of that output. The study could help make climate-change models...
...find the structural mechanism for the HIV virus’s drug resistance, we can see how those mutations will react with the drug molecules and better design drug therapy,” said Jing Zhang, a postdoctoral fellow at Harvard and the lead author of the paper...
...These are the heaviest boys who are shifting even further out," says CDC epidemiologist Cynthia Ogden, the lead author on the paper. "We didn't see that among the other kids, and we don't have an explanation...
...paper in Proceedings of the National Academy of Sciences makes that argument a lot harder to sustain. João Zilhão of the University of Bristol, along with several colleagues, has uncovered Neanderthal jewelry from two caves in southern Spain dating to about 50,000 years ago. "This," says Zilhão, "is 10,000 years before modern humans arrived. There is no question that Neanderthals are their makers...
While scientists have been able to determine the energy of hydrogen using paper and pencil since the 1930s, they now know they can use a quantum computer to perform this—and hopefully more complex calculations—with precision. Using classical computers, calculating the energies of larger molecules was virtually unimaginable because “the numbers get literally astronomical,” according to University of Queensland Physics Professor Andrew G. White, one of the authors of the study published in “Nature Chemistry?...
