...seem like a tempest in a test tube, but it has mightily agitated the scientific community and is now being debated in Congress. The question at issue: Is it dangerous, and possibly sacrilegious, to tamper with the genetic codes that control life? This week's cover story explains how some molecular biologists have become genetic engineers, and it details the controversy that surrounds their experiments. The story aims at providing a thorough understanding of the issues involved in deciding if steps are needed to curb, or stop altogether, the work being done in creating genetic hybrids...
...could have made your article on the FDA saccharin ban [March 21] more informative by including a statement on why large doses are used in tests. Such doses are necessary because the effects of carcinogens are cumulative, often taking 20 years or more to produce symptoms. The lifetimes of test animals are short, and a decision has to be made within a few years to protect the public...

...descendant of World War II's German V-l "buzz bomb," the cruise is small (a typical model is about 20 ft. long and 20 in. in diameter) and relatively cheap (well under $1 million each). Different versions have been successfully test-fired from submerged submarines, surface ships and B-52 bombers. Most earlier versions of the cruise-such as the Mace, the Snark and Regulus I-were primarily tactical weapons. Technological advances in recent years have given their successors, the Navy's Tomahawk and the Air Force's ALCM, a powerful, strategic wallop. Guided by miniaturized...

Says one Schlesinger aide: "He is really a seminar leader." He likes to use the sessions to test ideas, and he throws out a lot. "We are really not sure which ones he is serious about," concludes an assistant. Even after he has reached a decision, Schlesinger is likely to end the session on a probing note. "If you think about this some more and decide it's crazy, come back," he will...
