Genetics Confirm Oral Traditions Of Druze In Israel DNA analysis of residents of Druze villages in Israel suggests these ancient religious communities offer a genetic snapshot of the Near East as it was several thousands of years ago. The Druze harbor a remarkable diversity of mitochondrial DNA types or lineages that appear to have separated from each other many thousands of years ago, according to a new study by multinational team.
Nutrition For The Growing Athlete: The Good, The Bad And The Ugly For millions of American children and teens playing sports, good nutrition is critical for maximum health, performance and normal growth. Yet, with all the information available out there, it's becoming harder than ever for a young athlete to filter truth from myth, and detangle the good from the bad and the ugly, says a pediatric sports nutritionist at the Johns Hopkins Children's Center.
Fruit Fly Avoidance Mechanism Could Lead To New Ways To Control Pain In Humans At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs. Researchers have now discovered that the important developmental switch from food attraction to aversion in the fruit fly larva is controlled by a timing mechanism in the brain and its sensory system. The study shows how this important avoidance mechanism has been recruited into evolutionary processes to promote development and could lead to new methods of controlling pain in humans and other animals.
