Many autistic children share a chronic flaw in the body's natural defenses against oxygen free radicals -- corrosive molecules in the body that can severely damage developing brain cells, scientists said Saturday in San Diego. The molecular havoc caused by free radicals -- natural byproducts of metabolism -- is believed to be a major factor in the cell damage that underlies aging.

For people with metabolic syndrome, there is no shortage of the warning signs for heart disease, stroke and diabetes. Now scientists at Yale University Medical School say they have found a molecular common denominator that may help explain why conditions such as obesity, insulin resistance, high blood pressure, high levels of cholesterol and triglycerides tend to cluster in some people.

Harry Beevers, 80, a UC Santa Cruz biology professor who made breakthroughs in the understanding of the cellular structure of plants, died April 14 at his home in Carmel after a brief illness. A native of Durham, England, Beevers earned degrees in botany and plant physiology from Durham University. After postdoctoral study at Oxford, he immigrated to the U.S. and taught at Purdue University in West Lafayette, Ind., from 1950 until moving to UC Santa Cruz in 1969. He retired in 1990.

Cholesterol is thought to be crucial to normal metabolism, but a team at Quark Biotech Inc. of Fremont has produced apparently healthy mice that are cholesterol-free. The team reported in the current issue of Science that it removed a gene that carries out the final step in the natural production of cholesterol. The mice, however, are smaller than normal and show poorer growth characteristics.

At least 4% of American youths age 12 to 19 -- and 30% of those who are overweight -- meet the criteria for metabolic syndrome, a condition that puts them at increased risk for diabetes and heart disease as adults.

One of the most persistent myths about weight loss is that people who have trouble shedding fat are simply cursed with a slow metabolism. "Metabolism is everyone's favorite scapegoat," says William Evans, director of the Nutrition, Metabolism and Exercise Lab at the University of Arkansas for Medical Science. Yet the metabolic rate -- a measure of how many calories your body needs to function -- is rarely responsible for weight-loss woes.

Question: I hear the phrase "metabolism" related to weight loss all the time in my gym. Can you tell me what it means and how to use it for losing a few pounds? CARLTON SCHUCK Shreveport, La. Answer: Metabolism is the sum of all chemical processes in the body that provide energy for the maintenance of life, says Richard Cotton, a spokesman for the American Council on Exercise.

Let's face it: No matter how many exercise books you read or classes you take, you probably still have fitness questions, and you're not alone. There's a dizzying array of health/fitness information to decipher. Furthermore, fitness isn't a one-size-fits-all proposition. Whether you're a mother-to-be, a desk jockey trying to stay fit or a senior with special needs, you need information to help you do the very best you can to lead a longer, healthier, more vigorous life.

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.
