Method to count the absolute number of individual protein molecules inside a living cell

Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively.

Men who smoke cigarettes may experience a significant decline in their capacity to father a child

Sperm from nearly two-thirds of the chronic smokers in the study failed a special test that measures the ability of sperm to fertilize an egg. On average, those men showed a 75 percent decline in fertilizing capacity when compared to nonsmokers. Lead researcher Loni Burkman, Ph.D., presented the results today (Oct. 17, 2005) at the American Society of Reproductive Medicine annual meeting in Montreal, Quebec.
