Those safeguards were put to a test last September, when the nuclear-powered Cosmos 1900, containing about 70 lbs. of radioactive fuel, began falling out of orbit. But before the satellite re-entered the atmosphere, an automated safety system kicked in. The reactor was separated from the satellite and shot into a higher orbit. If, however, the reactor should collide with a defunct satellite or some other piece of debris left from more than 30 years of human activity in space, it could be knocked out of orbit anyway. Says Daniel Hirsch, director of the Stevenson Program on Nuclear Policy...
Behind the talk of interparty cooperation, the lines are being drawn for some nasty intraparty fights -- over personnel now and policy later. The toughest test that Bush and Baker face on the home front of their foreign policy will not be whether they are able to sit down and compromise with the Democrats but whether they are able to stand up to their fellow Republicans...
...roommates may try to tell you I'm a little bitter about this entire activity because I failed my first ski lesson--learning to stop. They'll utter something about how 90 percent of my group passed the screening test and were allowed onto the slopes, while I was kept back for four hours on a one degree incline practicing the snowshoestop position...
...students, the shortened shopping period is a logistical nightmare. Last term, undergraduates officially had eight days to test the waters, but classes actually met on only five of those, with many not convening on Friday as well. In addition, those lectures that were held often ran short on space and syllabi, making it impossible for students to receive an adequate impression of the course. Toss in a major Jewish holiday on Wednesday, and the result was pure chaos...
This limited test is only the beginning. The NIH researchers and others elsewhere are planning to transplant genes that could actually help people fight cancer and other diseases. For example, scientists hope to give patients genes that will enable their bodies to mass-produce such anticancer agents as interleukin-2 and tumor necrosis factor. Anderson believes the day is not far off when it will be possible to transplant a gene containing instructions for the manufacture of CD4, a substance that combats the AIDS virus. Ultimately, researchers think they may be able to conquer some hereditary diseases by replacing defective...
