...filtered over from the Centre de Genetique Moleculaire laboratory near Paris that scientists there were encountering the same anomaly. As the two groups report in a recent issue of the British journal Na- ture, additional experiments showed that whenever the Paramecium's cellular machinery read either of two "periods" (TAG and TAA) in the standard code, it linked the amino acid glutamine onto the protein chain rather than stopping production; it obeyed only the third word for stop, TGA. At Nagoya University in Japan, scientists have found that Mycoplasma also ignores a stop triplet. But in this case...
...constructed, Soviet personnel present a similar problem. Whereas the Russians bring to Washington an entire retinue of maintenance workers and cleaning people, the U.S. employs 211 Soviet citizens in similar capacities at its embassy. All are presumed to have at least informal ties to the KGB, and American personnel tag along as they do their chores. The State Department now has bowed to pressures from the intelligence community and agreed to remove most of the Soviets from their embassy jobs at some future date...
...ground near a group of missile silos or a city and fire electron beams at incoming "physics packages" (a remarkably polite euphemism for atomic warheads) as they re-enter the atmosphere. The beams, however, are hard to aim and control. Not to mention the price tag: Researcher Bill Barletta figures this one small part of a defensive system might cost $20 billion. Says he: "If we can't do it for that price, we shouldn't bother proposing...
...inevitable guessing game over such code names as Seek Axle, Have Flag, Cactus Plant and Theme Castle. Some experts believe that Aurora is the budget heading for "stealth" technology, which one day could make a plane or cruise missile invisible to enemy radar. Aurora's price tag: $80 million in 1986 and a hefty $2.3 billion...
...think she's a victim of overexposure," says Freddy DeMann. Freddy manages Madonna, not Cyndi, and frets - is, in fact, "absolutely worried" - that all the p.r. heat might burn out his client. Now, then. While the ladies play tag with the limelight, a few thoughts occur...
