...menstrual cycles, fewer infertility problems and a milder menopause than celibate women and women who have sex rarely or sporadically. So the researchers were hardly tentative about the meaning of it all. "What we're saying here is that men are really important for women," said Winnifred Cutler, a biologist and specialist in behavioral endocrinology who conducted the study along with Organic Chemist George Preti. "If you look at all the data, the conclusion is compelling. A man or his essence seems essential for an optimally fertile system." Nor did Cutler shrink from the commercial possibilities. "My dream," she said...
...September the Soviet weekly New Times reported that Jacob Segal, a retired East Berlin biologist who is unknown to Western AIDS experts, claimed that the virus originated in biological-warfare experiments at Fort Detrick, Md. Segal's allegation resurfaced in Zambia, then in London's Sunday Express, which cited support for the charge from Robert B. Strecker, an internist in Glendale, Calif., and John R. Seale, a British expert in venereal diseases. Strecker, who has written that the AIDS virus could have originated in either a natural or an artificial combination of viruses, dismisses the biological- warfare angle as "just...
...journal Science, is significant not so much as a demonstration of virtuoso genetic engineering, but because it will provide scientists with a valuable research tool for studying how genes go about their business. By fusing the firefly gene to the genetic material of other plants and animals, biologists gain a visual cue $ that will help them understand in detail how genes -- strands of DNA whose structure acts as a sort of coded instruction manual -- tell different cells what their duties are within an organism. Armed with such specific knowledge, researchers may someday understand exactly why these instructions are occasionally garbled...
...infection with these viruses does not always lead to malignant growth. In fact, that happens infrequently. Explains M.I.T. Biologist Nancy Hopkins: "Cancer arises from a number of insults to the DNA. Viruses are one insult. They start the process rolling." Years usually elapse between infection and the development of a related cancer. When liver cancer strikes a hepatitis carrier, for example, it generally does so 30 to 50 years after the victim was first infected. These long delays, Zur Hausen observes, "suggest the need for other events besides infection to occur in order to progress to cancer...
...more and more women into the work force. Following the rampant inflation of the 1970s, having two incomes was the only way many households could maintain their standard of living. For some families, however, two salaries have been enough to lift them out of the middle class. Neither Biologist Cam Patterson nor his wife Dorothy, a library assistant, both 37, has a particularly high- paying job. But their combined salary of $58,000 is enough for them to afford the $300,000 house they are building in Normal Heights, Calif. Even though the Pattersons hardly feel like the upper crust...
