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.

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.

It's another round of legal woes for the Bolshoi Theatre in Moscow: One of its top dancers is suing the company to annul two reprimands he received for talking to the media.

Sixty people who had to leave their homes after a train derailment released toxic fumes earlier this week were allowed to return on Friday. Hazardous materials crews had neutralized and removed most of the soil contaminated when a 65-car train derailed and spilled toxic phosphoric and hydrochloric acid Monday near the community 140 miles southeast of Palm Springs by the Salton Sea, Riverside County Fire Capt. Fernando Herrera said. All of the acid had been removed, and air quality readings indicated no hazardous vapors.
