Leslie Orgel, the Salk Institute theoretical chemist who was the father of the RNA world theory of the origin of life and who joined with Nobel laureate Francis Crick to postulate that life might have been seeded on Earth by a higher intelligence, died at the San Diego Hospice & Palliative Care on Oct. 27 from pancreatic cancer. He was 80. Reasoning that DNA was too complex to have been the first repository of genetic information, Orgel and others speculated that RNA could have preceded it, simplifying the evolutionary process.

Most scientists are fortunate to be involved in one major discovery during their lifetime. Sydney Brenner, who received the 2002 Nobel Prize in physiology or medicine, has been involved in at least three. One, for which he received this year's prize, was the idea to use the nematode Caenorhabditis elegans as an experimental subject to study the birth and death of cells in living organisms.

President Clinton on Tuesday signed an executive order limiting the use of genetic information by federal agencies in hiring and promotion as the availability of such data is exploding. The order prohibits federal agencies from collecting genetic information from their 2.8 million civilian employees or using such information to make hiring, promotion or placement decisions.

Simple blood tests have been developed in recent years that use genetic markers to identify hereditary leanings toward certain diseases. The tests give valuable early warnings but also are a potential source of discrimination, providing reasons for denial of employment or insurance coverage. Proposed federal legislation would go far toward blocking that threat.

A prestigious coalition of health experts and ethicists Thursday called for legislation or other measures to protect against abuse of an individual's genetic information in the workplace--for example, using the data to deny jobs, promotions, insurance coverage or other benefits. In recent years, rapidly growing technology and other advances have enabled geneticists to find disease-related genes in human DNA and to develop new tests to detect who carries them.

UCLA molecular biologist Larry Simpson will report today at a meeting of the American Assn. for the Advancement of Science here that he and his colleagues have discovered a new class of molecules that contain genetic information. The new molecules were isolated from a family of parasites, called kinetoplastids, that cause widespread tropical diseases, such as Chagas' disease and sleeping sickness.

Researchers have discovered an unprecedented and unsuspected deviation from one of the fundamental dogmas of molecular biology: that all genetic information is contained in deoxyribonucleic acid (DNA) and that this information is faithfully copied in the production of proteins and other cellular components. The discovery may trigger a fundamental rethinking of mechanisms by which genetic information is converted into living organisms.

The first strong proof that psychiatric illnesses can be inherited has emerged from a decade-long study, and the discovery could be a major advance in the detection and treatment of mental illness, scientists are reporting today. In a report published in Nature magazine, a leading British science journal, researchers from three U.S.
