New evidence that chubby people have sluggish nervous systems may help explain one of the great injustices of dieting--that some people burn up calories more quickly than others. The study, published in the New England Journal of Medicine, supports the theory that many fat people get that way because their bodies are extra-fuel efficient. Earlier research has documented that obese men and women often have lower metabolic rates.

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.

The first concrete evidence that stuttering and a second speech disorder called spasmodic dysphonia are caused by biochemical abnormalities rather than by emotional disturbances was presented here Monday by University of Texas researchers.

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.

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")

"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.

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.
