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.

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 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.
