...made from increasingly costly petroleum products. But scientists using plasmids have already cloned some of the nitrogen-fixing genes found in bacteria. And in an experiment at Cornell, a complete set of 17 such genes was transferred from bacteria to yeast, a slightly higher organism. The ultimate goal: to insert these genes in the plants themselves...
Like Berg, Cohen wanted to insert new genes artificially into bacteria. But where Berg resorted to a virus as his transport system, Cohen opted for plasmids, which he had been studying in his lab. As he listened to Boyer's description of his work that night in Waikiki, however, Cohen realized that there might be a short cut. Boyer and his associates had found a so-called restriction enzyme that cuts DNA precisely at predetermined points, and performs this surgery in an especially helpful way: at each end of the severed, twin-stranded molecule, it leaves an extra...
...does have drawbacks. It can be difficult to insert and remove, especially for women with long vaginas. But the cap has a decided advantage over the diaphragm: it can be reliably left in place for several days (against hours for the diaphragm) and thus affords greater sexual spontaneity. There is even promise of a cap that could be worn for years. In Chicago Gynecologist Uwe Freese and Dentist Robert Goepp are experimenting with custom-fit devices that have a one-way valve to allow menstrual blood to escape automatically...
...Administration, the U.S. is already moving toward a national financial market. Merrill Lynch, the brokerage firm, allows customers from nearly any state to write checks against their money-market accounts through an agreement with Bank One of Columbus. Holders of American Express Gold Cards will soon be able to insert the cards into automatic teller machines around the U.S. and withdraw cash from their home bank accounts. New York's Citibank plans to move its 5.8 million-customer credit card operation to South Dakota to take advantage of higher interest rates permitted there. San Francisco's Bank...
...long-standing prohibition against such distribution by student groups. However, this rule has rarely been cited, let alone enforced, when non-gay groups asked to make use of the packets. Indeed, the Women's Clearinghouse, the Student Assembly, Room 13, and other organizations have been allowed to insert folders...
