Natives of India's Andaman Islands, once famed for their ferocity and unique appearance, are genetically separate from their neighbors and may be descendants of Stone Age settlers, researchers said. Analysis of DNA from samples taken in recent times and 100 years ago show the Andaman Islanders, which include a group known as the Jarawa, are genetically different from other South Asians. The islanders, who are on the verge of extinction, have a distinct language and culture.

An international team of researchers today reported "the first concrete evidence" that schizophrenia can be caused by a genetic defect. Studying seven Icelandic and British families in which 39 of 104 family members were schizophrenic, the researchers found that all the affected individuals shared a specific segment of deoxyribonucleic acid (DNA) that they believe contains the abnormal gene. Schizophrenia is a severe mental illness that affects one in every 100 people.

A controversial conference on genetics and crime sponsored by the University of Maryland was disrupted by demonstrators who charged that the event smacked of racism. As the meeting got under way in Queenstown, the demonstrators, who had come in vans, burst into the conference room, waving red flags and chanting: "Maryland conference, you can't hide. We know you're practicing genocide," and, "Jobs yes, racism no. Genetics conference has to go." The conference resumed after the hourlong protest.

A radical new finding that genes passed on by fathers may be different from those passed on by mothers may explain many puzzling cancers and inherited diseases, researchers announced last week. The finding contradicts one of the principles of modern genetics. Dr.

A conference exploring possible links between genetics and crime was postponed Friday because federal money was withheld amid criticism from black leaders. The decision by the National Institutes of Health to freeze $78,000 earmarked for the meeting at the University of Maryland in College Park amounts to an assault on academic freedom, a university official said. The institutes decided in July to withdraw funds for the conference, scheduled for Oct. 9-11.

Canadian researchers have identified a mutant gene that impairs the body's ability to handle vitamin B12, producing diseases that are accompanied by an increased risk of heart disease, stroke and dementia. The team reported this week in the journal Nature Genetics that a defective form of a gene called MMACHC interferes with the vitamin's ability to help synthesize red blood cells and maintain the nervous system.

A computer jockey named Michael Richards punches a keyboard to search a database of chemicals kept at a biotechnology company here. With a few keystrokes, he calls up one of the more unusual inventory lists in corporate America. "Harsh but sweet, floral-hay odor; sweet cherry-berry taste," reads the entry for a chemical called 1-acetyl-4-methyl benzene. "Fruity, floral, weak, vanilla-like odor and taste," says another entry, for 4-methoxybenzyl acetate. The chemicals at Senomyx Inc.

Scientists have identified a gene that plays a central role in the development of obesity and diabetes and could pave the way for new drugs to treat the diseases. Researchers at Harvard School of Public Health in Boston discovered that mice genetically prone to obesity or those fed a high-fat diet had higher activity in a gene called JNK than normal mice.

Researchers at Childrens Hospital of Los Angeles and the USC School of Medicine say they can now identify many people who have inherited a defective gene known to be responsible for retinoblastoma, a childhood cancer of the eye. The report in the current issue of Science is the latest from scientists who have isolated the gene. The Childrens Hospital team said its study provided the first proof that the gene that was isolated is indeed the gene responsible for the cancer. Dr.

Lung cancer appears to run in families, researchers have found, though exposure to tobacco smoke is still the dominant cause of the disease even for those who may be genetically predisposed. The strongest family link was found in the relatives of patients who developed the disease at age 60 or younger. The parents of such people had nearly a 3 1/2 times higher risk of also developing the disease compared to the general population, the study said.
