...tests showed that women who use cervical caps rather than diaphragms initially have a higher rate of abnormal Pap tests, a possible sign of infection as well as cervical cancer. Consequently, the FDA recommends that the cap be prescribed only for women with normal Pap smears. It also suggests that a Pap test be performed after three months of cap usage. Even so, researchers see no health drawbacks to the cervical cap. However, they are quick to note that the newly approved contraceptive will not be for everyone; some women, for example, may find the device difficult to insert...
...interest in the novel fuel has been rekindled by news that the Soviets have conducted a successful test flight of a Tupolev Tu-154 passenger jet modified to burn a mixture of liquid hydrogen and natural gas. The three- engine jet, which lifted off near Moscow and flew for 21 minutes, was the first aircraft to use the fuel in takeoff. Says Senator Spark Matsunaga, a Hawaii Democrat and a leading advocate of a U.S. hydrogen-fuel research program: "It appears that the Soviets have stolen a technological march...
...hydrogen is the only combustible that ignites fast enough to boost the craft to orbital velocity, roughly 25 times the speed of sound. The frigid fuel could also be used in a cooling system to keep the plane from burning up during its fiery re-entry into the atmosphere. Test flights are scheduled...
...test the limits of dissent in the post-Kadar era, some 3,500 environmental activists took to the capital's streets late last week to protest the construction of a hydroelectric dam on the Danube River. In the face of bobbing placards and charged speeches, the police kept on the sidelines, and the march was orderly. But it signaled the restlessness that Grosz, 57, will face as he tries to cope with economic stagnation. During his first week as party General Secretary, Grosz vigorously repeated his support for the market-directed policies he insists are necessary to revive the Hungarian...
Even so, there are other, more formidable barriers. Past cooperative space ventures have been closely tied to politics. The 1975 Apollo-Soyuz mission, for example, sprang from an earlier era of detente. The costly linkup between the orbiting U.S. and Soviet capsules (price tag: $300 million) was promoted to test compatible docking systems but had little scientific value: the flight was the last for the Apollo program. Prospects for more joint missions disappeared in December 1979, when the Soviets invaded Afghanistan. "These missions start for policy reasons and stop for political reasons," says Nancy Lubin, a Government expert...
