...immediate hope of discovering a vaccine to inoculate people against the AIDS virus. And few new drugs are on the horizon that might alleviate or cure the disease. Said Dr. Harold Jaffe, chief AIDS epidemiologist at the Centers for Disease Control in Atlanta: "The strides made in the molecular biology of the virus are just phenomenal. But that hasn't yet translated into something we can use to stop...
...book will have contributions from members of the Harvard faculty, including Professor of Geology Stephen Jay Gould, Professor of Microbiology and Molecular Genetics Jonathan R. Beckwith, and Professor of Biology Ruth Hubbard, as well as works by several undergraduates and some outside contributors, but most of the articles have been written by the members of Students for Empowerment...
Anton Hopfinger, a chemist at the Chicago campus of the University of Illinois, is using computer graphics to identify the site where adriamycin, a chemotherapy drug, binds to cancer cells. "Molecular graphics has been a real boon to the study of large molecules and proteins," he says. "You can think of it as the equivalent of landing an airplane on an aircraft carrier, except in this case you're sitting on the drug molecule and landing on the DNA molecule. If you didn't have graphics, it would be like being blind and still trying to land on the aircraft...
Forcing the pressure higher than that had no effect; it was time for more wild thinking. Chu reasoned that the high pressure worked because it squashed the compound's molecular structure and that this somehow boosted its superconducting temperature. Since more pressure did no good, Chu decided to compress the molecules in a different way -- from within. He replaced the barium with strontium, which is similar chemically but has a smaller atomic structure. Sure enough, the temperature rose again, to 54 K, then stopped. So he turned to calcium, an element with even smaller atoms. This time the temperature dropped...
Geha said that next year he will study molecular immunology. He described this field as a new technology which he needed to learn, and said he wished to do so "away from the hassle of everyday life...
