Using powerful new tools, biologists at the University of Chicago have gently sliced through a red blood cell to peer at individual protein molecules clinging to its inner membrane. At the California Institute of Technology, chemists have watched in wonder as a hydrogen atom romances an oxygen away from a carbon dioxide molecule. And at Stanford University, physicist Steven Chu has mastered techniques for levitating millions of sodium atoms inside a stainless-steel canister and releasing them all at once in luminescent fountains. Of late, Chu and his colleagues have amused themselves by stretching a double-stranded DNA molecule...
...infrared laser light, scientists can seize and manipulate everything from DNA molecules to bacteria and yeast without harming them. Among other things, optical tweezers can keep a tiny organism swimming in place while scientists study its paddling flagella under a microscope. Optical tweezers can also reach right through cell membranes to grab specialized structures known as organelles and twirl them around. Currently, researchers are using the technology to measure the mechanical force exerted by a single molecule of myosin, one of the muscle proteins responsible for motion. Scientists are also examining the swimming skill of an individual sperm...
...forgotten. On this bleak day, Anderson was relaying silent messages to Sutherland, who would pass them on to Keenan, and so forth. Then calamity struck. "I took off my glasses and dropped them and broke them," he said. "My eyes are very bad. Couldn't see." End of silent, cell- to-cell dialogue. End of story. "That was a bad day," he concluded, the sorrow returning for a moment with the memory...
...different reasons and at different times, some of the hostages surrendered to despair. Anderson's former cell mates recall how in December 1987, when the journalist was forbidden to send a Christmas message to his family, he slammed his head against a wall until the blood streamed down. "There were times when I was near despair," he said last week. "I don't think I ever quite gave up." Sutherland, who shared a cell with Anderson through most of his 2,353-day captivity until his release last month, revealed that he had attempted suicide three times. "I tried...
...existence," Sutherland told TIME that when the large Waite moved, "it was like a goddam herd of elephants." When Waite joined Sutherland, Anderson and others after enduring four years of solitary, he understandably hungered for companionship -- but he had a hard time adapting to the courtesies of a shared cell. "Other hostages had a sense of when people needed privacy and didn't want to talk," Sutherland said. "Waite wanted to talk constantly, ask stupid questions...
