Cancer researchers at Duke University Medical Center in Durham, N.C., have been studying the DNA in tumors called glioblastomas - hoping, ultimately, to help find a cure for the disease.   They haven't found that yet, but they may have come across something else scientists are seeking: an enzyme that could help companies make nylon without depending on fossil fuels. Duke researcher Zachary Reitman and colleagues reported Sunday in the journal Nature Chemical Biology that inserting glioblastoma genes into yeast allowed them to make an enzyme called 2-hydroxyadipate dehydrogenase - a molecule chemists need to make adipic acid, a key ingredient in nylon, from sugar.  Today, adipic acid, which is produced in vast quantities, is made using petroleum products.

A University of California chemist believes the root bark of an African tree may provide a method of birth control for cockroaches. Isao Kubo hopes that lacing roach food with a chemical called anacardic acid, found in the bark of the msimbwi tree, could be the answer. "If we can feed it to them, it's a new way of control," he said before presenting his findings recently in Miami Beach to a meeting to the American Chemical Society.

If each vehicle is to carry 32 10-volt battery packs, how about the disposal of lead acid in the batteries? That's 32 gallons of it per vehicle to be discarded each year. If California's 20 million vehicles produced 640 million gallons of non-recyclable waste annually, would it be poured into the ocean or allowed to sink into the soil? RON OEHLKERS Venice Marla Cone responds: Lead acid in batteries is recycled, so there should be no significant disposal problem.

Move over, omega-3s . There's a new fatty acid in town that might make you healthier. Something more closely associated with creamy pleasure than with fish burps. Trans-palmitoleic acid, a fatty acid that circulates at higher levels in the blood of those who consume lots of full-fat dairy products, may protect against diabetes, according to a study published Monday in the Annals of Internal Medicine . That surprising finding may fly in the face of much nutritional advice that warns us against consuming too much whole milk, cheese or other sources of animal fat. But it comes from a study of 3,736 adults participating in the long-running Cardiovascular Health Study . It also proceeds from a suspicion that researchers have had for a while, but found difficult to prove: that the fatty acid palmitoleate, which humans produce in their liver and fat, and consume in dairy fats, may play a complex role -- beneficial and harmful -- in regulating metabolism . By measuring just the palmitoleate that came from consumption of dairy fats, researchers were able to discern the side of this fatty acid that may contribute to good health.

SOME CALL them kinky. Some say they stink. And others just plain hate them. Yet 80% of salon patrons won't face their mirrors without a perm. According to Modern Salon, a hair-care industry trade journal, permanent waves are the second-most-requested service after haircuts in U.S. beauty shops. Despite the proliferation of gels, mousses and curling tools, perms remain popular because of the long-lasting body, versatility and wash-and-wear convenience they provide. Reacting to the public's love-hate relationship with the perm, manufacturers and stylists are in constant pursuit of the perfect wave.

A Rembrandt masterpiece, damaged by an acid-throwing vandal at the Hermitage museum in Leningrad, is undergoing restoration by art experts, Pravda said Thursday. Experts initially feared that the painting, "Diana Is Saved", had been damaged beyond recognition. "Today, one can say with confidence that people who live in Leningrad and those who come to visit the city will be able to see the work of the great master made in 1636 in its place again," the Communist Party said.
