...warden, Harold Swenson, 58, a longtime associate in the federal system, quickly established a new climate. Knives and forks -hitherto forbidden as potentially dangerous weapons-joined spoons on the dining tables; fresh fruit appeared on the breakfast menu; shower rooms were placed at the end of each cell-block tier so that convicts could bathe daily instead of twice a week. Cheap transistor radios were put on sale. For the first time, maximum-security prisoners were allowed outdoors for recreation and supplied with pillows and mattresses instead of back-breaking straw ticks...
Stern Side. A burned-out cell block, still standing a decade after the riots, was replaced by a prisoner-built recreation building that has become the home of the Versatiles, an eight-man convict combo that performs at schools and other state institutions. Most important, the prison population has been reduced by 20%. Yet a truly professional administration also has its stern side. Guards, who had often snoozed in overstuffed chairs in the watchtowers, were now perched on high aluminum chairs and provided with M-l carbines and sawed-off 12-gauge shotguns in place of puny .22-cal. rifles...
Electron microscopists have since photographed lysosomes, and Dr. de Duve, now at Rockefeller University, has figured out some of the ways they work (see diagram). In a typical case, a foreign particle (it may be a virus, a bacterium or a chemical) reaches the side of a cell and is sucked in, sealed off by a piece of the cell's own membrane. Standing by inside the cell is a lysosome, packed with enzymes. Lysosome and invader, now packaged in a phagosome, are drawn together and fuse. In the resulting sac, called a vacuole, the foreign substance is digested...
Usually, that is good; the harmless debris may be either left in the cell or expelled from it. But in the case of some viruses, the effect may be to bare the virus particle's nucleic acid and leave it free to infect the cell. Moreover, as New York University's Dr. Gerald Weissmann reported in Michigan, some virus particles can survive a spell in a digestive sac, and emerge from it with their infective powers intact. By another mechanism, lysosomes can be directly harmful: they may, for reasons not yet guessed at, attack part of their...
...humid climates-contains high concentrations of ammonia. To detect the ammonia, the E63 scoops up air, passes it over a wick saturated with hydrochloric acid and into a humidifying chamber. If the air contains any ammonia, a fog forms, changing the amount of light shining on a photoelectric cell and varying the amount of electric current that it produces. The current variation in turn increases the frequency of a beeping sound in the operator's headphones and produces a higher reading on a meter, warning him that there are men near by. Higher concentrations of ammonia-presumably produced...
