Therapeutic value of meditation unprovenThere is an enormous amount of interest in using meditation as a form of treatment to cope with a variety of modern-day health problems, particularly hypertension, stress and chronic pain, but the majority of evidence that seems to support this notion is anecdotal, or it comes from poor quality studies, say Maria Ospina and Kenneth Bond, scientists at the University of Alberta/Capital Health Evidence-based Practice Center in Edmonton, Canada.

Gene That Spurs Development Of The EpididymisHuman sperm cells travel up to 6 meters in their transit from testes to penis, and most of that journey occurs in the epididymis, a tightly coiled tube that primes the cells for their ultimate task: fertilization. In a paper released this week in the Proceedings of the National Academy of Sciences, scientists at the University of Illinois report that they have discovered a gene - and related mechanism - essential to the embryonic development of........Go to the Research news blog (Added on 6/27/2007 6:44:09 PM)
