Endorphins

An addiction to opiates produced by the brain while dieting may be the cause of anorexia nervosa, an eating disorder in which patients starve themselves, sometimes to death, Michigan researchers said last week. The scientists say their research, presented at the 40th annual meeting of the American Society for Pharmacology and Experimental Therapeutics, suggested anorexics may have "abnormal biological responses" to diet-triggered opiates.

Later this month, kisses will be exchanged on cards, in boxes of candy -- and, of course, on the lips. Scientists know how humans kiss and what happens to the body during a kiss, but why people began puckering up in the first place remains unknown. A romantic kiss, blandly stated, involves movement of the lower jaw (the sole movable bone in the head) and contraction of 34 muscles in the face, neck and head -- principally the orbicularis orbis, which surrounds the mouth and allows the lips to pucker.

Hans W. Kosterlitz, 93, biochemist whose discovery of opiate-like substances fostered research on painkillers. In 1975, Kosterlitz and his former student John Hughes discovered enkephalins, naturally occurring substances in the brain. They continued to study brain substances, which as a group are called endorphins. The breakthrough paved the way for major research into new kinds of nonaddictive painkillers.

Our two most recent presidents have been joggers. They run to purge the Oval Office air from their lungs and the political poisons from their brains. Two powerful men, both runners, both setting an example for the nation. But I don't let that deter me. "You're running this morning?" my wife asks. "Uh-huh," I say. "Good luck," she says. She's seen me run--strong, powerful strides, arms flopping every which way. Like someone playing tennis without a racket. Like someone dodging bottle rockets.

Every time I write about a high-performance sports car, I'm guaranteed to get letters from readers to this effect: "How can you possibly glorify the Badminton Dual-Cowl 87B? No one needs a car that goes 200 mph, costs $300,000 and gets five miles per gallon. With all that's going on in the world [climate change, war in the Middle East, balance of trade etc.]. For shame. For shame!" All right, then. I present to you perhaps the most fun available on four wheels: The 2010 Lotus Evora.

Romantic attraction is often described as a mysterious chemistry, a storm of electrified feelings that occurs when one's vision of loveliness or hunkiness stands near. Flutters erupt in the belly. The heartbeat quickens. Adrenaline rushes to the bloodstream. Hallucinogenic feelings of intoxication drench the brain. Call it a natural high, but like drugs, the feeling can become addictive. During the opening stages of romance and subsequent infatuation, the brain is awash in drug-like chemicals.

The premise Nurse Jackie Peyton (Edie Falco) is having trouble managing her growing addiction to painkillers. Nevertheless, she continues to snort an opiate in the supply room and pop pills in the bathroom during shifts at the hospital. Jackie works in the busy emergency room, where she helps take care of a boy who wedged a dental mirror up his nose because he was trying to see his brain. Later, another young man is brought in after being found crushed under 2 tons of books (he and his father were part of a moving team that were clearing a library that was closing)

When I do cardio, I seem to sweat more than most people. I notice that some people do not seem to sweat at all, even when working out hard. Am I burning more calories, or just not as fit as I should be? Peter Ventura The more you contract your muscles during exercise, the more heat you produce. Sweat is necessary to cool the body while exercising because it prevents you from overheating. However, your environment, exercise intensity, fitness level, gender and genetics all play a role in how easily and how much you sweat.

It isn't often I get a book that makes me laugh. Gorman tells us "that the purpose of science is to provide us with something to talk about when art and poetry and music lose their appeal."

Just beneath the pale softness of her Botticelli face some vague hint of trepidation shows as Suzanne Farrell floats into the lobby of the Chateau Marmont. Her uneasiness, masked perhaps by the calm and quietude that surrounds the hotel, is almost palpable. But nothing is different. Farrell has always made her aura palpable.
