...imental network of optical fiber, where each fiber carries data on multiple wavelengths of light (lambdas) to connect distributed computing resources at speeds equivalent to internal PC bus speeds. Each lambda can transmit data at 1 to 10 Gigabits per second (Gbps), and soon will achieve 40 Gbps and greater ...Obesity not a personal failing, but a battle against biology
...ficials have been sounding an alarm, since obesity carries an increased risk for heart disease, high blood pressure and diabetes. And even more disturbing is the increased incidence of type 2 diabetes in children -- which public health officials blame on the obesity epidemic in young adults. Friedman points ...Purdue researchers connect life's blueprints with its energy source
... RNA - well-known as the "messenger molecule" that carries instructions between DNA strands in a cell's nucleus - could serve as a catalyst for important chemical reactions in the body. The discovery of these RNA catalysts, called ribozymes, convinced many scientists that RNA probably existed on earth before...Computer model offers noninvasive evaluation for abdominal aortic aneurysm rupture risk
...to the weakened area. "But because surgical repair carries its own risks, being able to pinpoint when an AAA is likely to rupture gives surgeons a valuable tool," said Elena DiMartino, Ph.D., a research associate in Pitt's department of surgery who is a member of Dr. Vorp's team and worked on the study.
