...realizing that drugs alone may not be enough. To contain the virus effectively, it may take a balance between drug therapy that keeps HIV levels low and a bolstered immune system that can then target and destroy the remaining virus. Until scientists find a vaccine, however, they may control but never cure the century's final scourge...
...filling laboratory books with page after page of failed experiments, Baekeland finally developed a material that he dubbed in his notebooks "Bakelite." The key turned out to be his "bakelizer," a heavy iron vessel that was part pressure cooker and part basement boiler. With it, he was able to control the formaldehyde-phenol reaction with more finesse than had anyone before...
...into the sky. They were the first to discover that a long, narrow wing shape was the ideal architecture of flight. They figured out how to move the vehicle freely, not just across land, but up and down on a cushion of air. They built a forward elevator to control the pitch of their craft as it nosed up and down. They fashioned a pair of twin rudders in back to control its tendency to yaw from side to side. They devised a pulley system that warped the shape of the wings in midflight to turn the plane...
...Bethe--formed the heart of the bomb squad. In 1939, still officially enemy aliens, Fermi and Szilard co-invented the nuclear reactor at Columbia University, sketching out a three-dimensional lattice of uranium slugs dropped into holes in black, greasy blocks of graphite moderator, with sliding neutron-absorbing cadmium control rods to regulate the chain reaction. Fermi, still mastering English, dubbed this elegantly simple machine a "pile...
Fermi proceeded imperturbably through the experiment, confident of the estimates he had charted with his pocket slide rule. At 11:30 a.m., as was his custom, he stopped for lunch. The pile went critical in midafternoon with the full withdrawal of the control rods, and Fermi allowed himself a grin. He had proved the science of a chain reaction in uranium; from then on, building a bomb was mere engineering. He shut the pile down after 28 minutes of operation. Wigner had thought to buy a celebratory fiasco of Chianti, which supplied a toast. "For some time we had known...
