Longer Life? 'Longevity'Genes Protect Very Old People From The Bad Gen
People who live to 100 or more are known to have just as many -- and sometimes even more -- harmful gene variants compared with younger people. Now, scientists have discovered the secret behind this paradox: favorable "longevity"genes that protect very old people from the bad genes'harmful effects. The novel method used by the researchers could lead to new drugs to protect against age-related diseases. Polaroid Sunglasses Let Astronomers Take A Closer Look At Black Holes

Scientists have identified a virtual "speed limit"on the rate of molecular evolution in organisms, and the magic number appears to be six mutations per genome per generation -- a level beyond which species run the strong risk of extinction as their genomes lose stability. Controlling Sexual Compatibility Can Help Control Spread Of Some Invas
When it comes to controlling invasive weeds, sex might be a useful weapon, according to research from UC Riverside geneticist Norman Ellstrand in an article in the Proceedings of the National Academies of Science. New Test For Most Virulent HPV Strains Under Study

For those who have wondered why they like or dislike certain things, or how they decide what to order from a menu, a team of researchers at the University of Colorado at Boulder says it's dopamine. Long-lived Deep-sea Fishes Imperiled By Technology, Overfishing
Many commercially prized fish from the depths of the world's oceans are severely threatened by over-fishing and the species' ability to recover is constrained by the fishes' long lifespans and low reproductive success, a panel of experts said at the annual meeting of the American Association of the Advancement of Science. Computers: Poor Placement Does Not Compute In Medical Exam Rooms
