  • Sperm Study

Two new studies are shedding light on some factors that could make a man infertile. The first study points a finger to lead. Researchers measured lead levels in the semen of 140 men and found that those with the highest levels of lead had the most trouble with the sperm connecting to an egg which, they say, might explain some unexplained cases in which the men appeared to have normal hormone levels. The second study simply circles age as a factor in male infertility. The study compared sperm speed in nearly a hundred men between the ages of 22 and 80. It found sperm slows down as men get older. Both studies are published in the journal human reproduction. The lead study was conducted by researchers at North Shore Long Island Jewish Research Center. The motility study is from the University of California at Berkeley.

  • Staph Discovery

Scientists have some new targets to aim for in the fight against Staph Bacteria. Staph infections account for hundreds of thousands of deaths each year in the U.S. but now, researchers at the University of Chicago have mapped how the germ grows and spreads infection. The key, they say, is iron. The bacteria can't grow without it. So, the study maps out a variety of potential targets to stop the germ - because, the theory is if you can keep it from getting iron, that means certain death to the Staph Bacteria. This study is published in the journal, "Science".

  • Helping Kids who Stuttering

Children who stutter don't respond well to advice that encourages them to slow down and relax. A survey by the Stuttering Foundation found that nearly 90% of parents interviewed would tell their child to relax, not realizing that advice would likely frustrate their child. The foundation says that most young children who stutter respond best to patient responses from parents as well as attentiveness to what the child is saying.
