Vladimir Apekin's wife and daughter are engaging in an indefinite hunger strike in the hope that they can persuade the Soviet authorities to let the refusenik leave the country for special medical care. Apekin, 49, a former marine biologist who was dismissed from his job after he applied to emigrate to Israel, was hospitalized in early March for a variety of ailments, including heart disease.

Chemotherapy, radiation treatments, organ transplants and illness can all depress numbers of platelets -- the cell fragments in the blood that help form clots -- in the human body. Patients often need platelet transfusions. Unfortunately, platelets are scarce. Today, hospitals depend on blood donations to get them, and once they're in hand, they have a very short shelf life: only about a week. But, researchers wrote Tuesday in the journal Cell Research , pluripotent stem cells -- that is, cells that have the potential to turn into any other type of cell in the body -- might one day provide a way to generate "an unlimited supply of platelets for transfusion" in the laboratory.

The Cray-2 is only four feet high and four feet in diameter, but the new $17-million device at NASA's Ames Research Center is the world's fastest, most powerful supercomputer. Because its micro-miniaturized electronic circuits are packed so close together, the compact machine is the first supercomputer to have components immersed in a colorless fluorocarbon liquid that prevents overheating. The liquid also often is used as artificial human blood plasma.

William Pope.L, the man behind the exhibition at the Santa Monica Museum of Art titled "Art After White People: Time, Trees, & Celluloid. . . ," has never shied away from confrontation. He once tied himself to the door of a Manhattan bank with sausage links and, clad only in a skirt made of dollar bills, tried to give the money away to passersby. Over a five-year span, he crawled along sections of Broadway, from Staten Island to the Bronx, wearing a Superman suit.

A year ago, the Navy gave Anthony Mulligan's company a small grant to build a cheap aerial drone for whale watching. The idea was to make sure marine mammals weren't around during sonar tests. Then came Sept. 11. And, with the help of an Arizona congressman, Mulligan transformed the drone into a potential weapon in the new war on terrorism.

In a major advance toward the development of artificial organs, bladders grown from patients' own cells in the laboratory have been successfully implanted in seven children with spina bifida and shown to function for five years or longer, researchers reported today. The achievement, reported online in the international medical journal the Lancet, marks the first time that artificial organs more complicated than skin and bone have been implanted in humans.

Ten years ago, Dr. Robert Ferguson conducted an improbable experiment. Using balloon angioplasty, a technique to unclog coronary arteries, he tried to open a blocked artery in a stroke victim's neck. The patient thrived, but Ferguson, a radiologist at Baptist Memorial Hospital in Memphis, was practically run out of medicine for taking the therapeutic gamble, which he believed was justified because the patient also had cancer, making him ineligible for standard surgical therapy. "There was great doubt that this made any sense," Ferguson said.

In the 1950s and 1960s, surgeons devised operations that revolutionized the treatment of peripheral vascular disease, a condition in which the arteries in the pelvis and legs are narrowed by a buildup of cholesterol and calcium clots in the vessel. The new advance was to install artificial blood vessels made of Dacron or to use one of the patient's veins to bypass the clots. These procedures prevented amputations and improved the lives of thousands of patients.
