...VLDL boats unload their triglycerides into body tissues, the carriers get progressively smaller, denser and proportionately more cholesterol-rich, ultimately becoming particles of LDL. The LDLs are then pulled out of the bloodstream by special protein receptors on the surface of cells. "These receptors reach out and grab cholesterol like a first baseman catching a ball thrown by a shortstop," says Dr. Michael Brown of the University of Texas Southwestern Medical Center, who, with his colleague Dr. Joseph Goldstein, won a Nobel Prize in 1985 for discovering LDL receptors. What happens to excess LDLs that are not taken...
...enough of the HDL vigilantes in his blood. Largely produced in the liver and the intestines, these flat, disklike particles resemble "empty envelopes waiting to be filled," says Dr. Norman Miller, head of endocrinology at North Carolina's Bowman-Gray School of Medicine. As the VLDL and chylomicron particles unload their triglyceride cargoes into the body's cells, the particles become wrinkled like prunes. In the process, fragments containing proteins, fats and cholesterol break away. It is at this point that the unfilled HDL particles come to the rescue by scooping up the detritus. Researchers believe HDL also removes excess...
...including one in which a looter was killed. The trail took police and archaeologists to a huge adobe platform at the base of a weathered Moche pyramid near Sipan. When the authorities arrived, they found men, women and children combing the area for artifacts dropped by the huaqueros, who unload the contraband on the black market for buyers in the U.S., Latin America and Europe. Driven off by police, the villagers viewed the new diggers as little more than government-protected thieves. Threats followed, including oaths of vengeance sworn by the relatives of the slain huaquero. Nightly, intruders were warned...
...five aborted engine tests so far have been due to fueling problems, specifically in lines that carry liquid hydrogen from ground equipment to the tank. After two of the failures, several hours were required to unload more than half a million gallons of liquid hydrogen and oxygen from Discovery's tanks before technicians could examine problems. NASA engineers are not certain exactly what caused last week's problem. Said Joseph Lombardo, who oversees the shuttle's main-engine project at Marshall Space Flight Center in Alabama: "We don't know whether it was a faulty indication or really a malfunction...
...problems begin at Massawa, the Red Sea port where hundreds of dock workers labor night and day to unload grain and other food destined for Ethiopia's hungry millions. Cranes are in short supply, as are trailers to store the grain. While wheat from the U.S. and Canada usually comes in bags, much of the grain from Europe does not and thus takes longer to unload. Grain sometimes arrives soaked with water; a recent shipment of milk powder was contaminated...
