A study of human-sized turtles suggests dinosaurs were able to regulate their body temperatures in warm and cool climates much like large mammals, researchers reported in the journal Nature. The study has added to a growing body of evidence that dinosaurs were not the sluggish, lumbering, cold-blooded reptiles depicted in Godzilla movies, but lively, sociable beasts that acted much like animals do today.

"Prolonged sitting is not what nature intended for us," says Dr. Camelia Davtyan, clinical professor of medicine and director of women's health at the UCLA Comprehensive Health Program. "The chair is out to kill us," says James Levine, an endocrinologist at the Mayo Graduate School of Medicine. Most of us have years of sitting experience, consider ourselves quite good at it and would swear that nature intended us to do it as much as possible. PHOTOS: 17 ways to fight the inertia, step by step But unfortunately, a good deal of data suggest that we're off our rockers to spend so much time on our rockers - as well as the vast variety of other seats where we're fond of parking our duffs.

Chromium is an essential trace mineral found in a variety of foods, including whole grains, cereals, spices (such as black pepper), broccoli, mushrooms, cheese, seafood and meat. In the body, it plays a role in metabolizing fats and carbohydrates and controlling blood levels of sugar. The body has a hard time absorbing chromium supplements in mineral form; it is absorbed more easily when it's bound to another molecule.

That's the bottom line of an unusual case report published in this week's edition of the New England Journal of Medicine. Doctors at the Henry Ford Health System in Detroit treated a 47-year-old woman who had suffered from pain in her lower back, hips, legs and arms. She was also missing all of her teeth because they had become brittle. Something was wrong with her bones. Sure enough, X-rays revealed that the vertebrae in her spine showed signs of a painful condition called skeletal fluorosis. Doctors gave her a blood test to measure the concentration of flouride in her system.

The cluster of symptoms collectively known as a metabolic syndrome heighten the prospect that with age will come steep cognitive decline, a new study has found. Researchers followed 7,087 French people over 65 for four years to see what factors were most clearly linked to losses in mental performance that fell short of dementia. Many seniors--including 15.8% of the sample--are diagnosed with metabolic syndrome , defined by these researchers as having two of the following five biomarkers: high blood pressure, a large waist circumference, a high overall cholesterol reading , a particularly low score on HDL (or "good")

Horace Albert Barker, 93, UC Berkeley biochemist, who made significant studies in the function of vitamin B-12. Internationally respected, Barker in 1944 helped pioneer the use of isotopic tracers to synthesize sugar, sharing the Sugar Research Award from the National Academy of Sciences. In the 1950s, he moved into vitamin B-12 coenzyme chemistry and later into bacterial metabolism, fatty acid oxidation and carbohydrate transformations.
