The discovery of an ancient heart of stone--the first ever found belonging to a dinosaur--reveals that many of these primordial creatures were almost certainly warmblooded, like a modern bird or mammal, researchers announced today. Detailed, computerized X-ray scans of the 66-million-year-old fossilized heart show that its muscular chambers could have pumped enough richly oxygenated blood for the primitive creature to caper, gambol and leap with all the abandon of an animated special effect.

Please do not propagate the misinformation that Laura Schlessinger is a "psychologist" ("Schlessinger Is Preparing Daily Syndicated Talk Show," by Judith Michaelson, May 6). Dr. Laura has a master's level license from the state of California as a marriage and family counselor. She has a PhD in physiology, not psychology or counseling. Funny that she uses the "Dr." in her radio psychology program, even though it misleads the public as to her genuine credentials and qualifications. SUZANNE R. LAKE, Pasadena

Brain scans of healthy adolescents reveal for the first time what many parents have long suspected--that teenagers don't think or feel the same way as adults, in part, because their brains actually work differently. The researchers discovered that teenagers not only process emotions more intensely and more indiscriminately than adults, but also appear to use their brains differently to handle what they are told.

Talk about leaving the rat race. Twenty-two baby rats, the research subjects of a UC Irvine professor, will be launched into outer space today aboard the space shuttle Columbia, to float about in their cages in zero gravity for 17 days. UCI's Kenneth Baldwin, professor of physiology and biophysics, hopes to discern information from the muscles of baby rats in space that could help gravity-bound humans on Earth.

Scientists reported the first strong physiological evidence that lesbian and bisexual women may be biologically different from heterosexual women. Researchers at the University of Texas in Austin found that the hearing of homosexual and bisexual women tends to be a bit more like that of men. The findings suggest that homosexual and bisexual women develop in subtly different ways than heterosexual women.

They lounge around the classroom and lean against cupboards. Some actually hang from the ceiling. They are the "trash bodies" completed by Thurston Middle School students this week, just in time for display at Thursday night's open house. "You walk into the lab and it's like, 'Aaaah!' " said science teacher Carrie Leventhal, making the sound of a stifled scream. "The night of the living dead."

They rush through you menacingly on a mountain trail when you mistake a twisted stick for a snake. They wash over you gently when your newborn looks your way. And when you gaze upon a Monet or call to mind a lilting line of verse, they bring you warmth. Feelings are woven through every human experience. But for all the anguished attention emotions have drawn from poets and lovers, science has done little to decipher their mysteries.

From a single cell, the human brain grows into the most complex object in the cosmos. As it grows, the brain is sculpted from the raw material of its cells, called neurons, and human experience. WIRING THE MIND A baby is born with all the brain cells he or she will ever have, but with relatively few connections--called synapses--between those cells. The connections are forged by the growing child's experience with the surrounding world.

Pedaling his tricycle in a suburban cul-de-sac, 5-year-old Austin Rawnsley is rebuilding the most complex object in the known universe--his own brain. With each revolution of the tricycle wheels, a living labyrinth of neurons fires to strengthen ties among brain cells that control his feet. Each time the steering wobbles, brain cells responsible for his hands respond in an expanding pattern of chemical and electrical signals that improve his dexterity.

Exercise and spirituality go hand in hand, and running can be a path toward a religious experience, according to researchers who have studied the connection. "A biological mechanism is at work," said William C. Bushell, a Massachusetts Institute of Technology research scientist specializing in medicine and anthropology. "Whatever creator made the body had this in mind. It comes out in physiological science like a clear blueprint."
