UT Southwestern receives $1.78 million grant for obesity research as part of NIH Roadmap initiative
...se of preventable death. "Obesity is a deceptively simple problem, as it is essentially energy input vs. energy output," Dr. Malloy said. "However, it's not obvious yet why obesity should necessarily accompany development of type II diabetes, cardiovascular and other diseases. These are problems that need t...DNA lends scientists a hand, revealing new chemical reactions
...n unexpected reaction that efficiently coupled two simple hydrocarbons, a terminal alkyne and a terminal alkene, to form a useful and more complex group called a trans-enone," Liu says.
