...Massachusetts researchers suggest that the answer lies in a simple mistake made back in 1905: when early researchers noted that the syphilis bacteria die on exposure to air, they assumed that the microbes were anaerobic, meaning that they could not live in the presence of oxygen...
...Charles D. Cox, at the University of Massachusetts in Amherst, this seemed paradoxical because spirochetes infecting humans or animals flourish in oxygen-rich blood and cells. With Technician Miriam K. Barber he began experimenting with a virulent strain of syphilis bacteria grown in rabbits. Using a recently developed, extremely sensitive technique for measuring oxygen concentrations, the two investigators found that the spirochetes, far from being anaerobic, consume oxygen in their metabolism. In the journal Infection and Immunity they suggest the "strong possibility" that oxygen is necessary for the reproduction and growth of the organisms. As to why they...
...illusions that his finding will lead to the immediate conquest of syphilis. He must find out just what nutrients and how much oxygen the spirochetes need. Then will come the task of getting them to multiply in the test tube. Only after that will it be possible to work on preparing a vaccine...
Carbon monoxide (CO) produces its poisonous effect by crowding out oxygen molecules that normally attach themselves, in the lungs, to the hemoglobin molecules in red blood cells. By a malign quirk of nature, CO has an affinity for hemoglobin more than 200 times as great as that of oxygen. Thus too much carbon monoxide starves the body of oxygen, causing illness and sometimes death-as in the case of the suicide who runs a hose from the engine exhaust to the inside of his car. But how many Americans are inhaling an excessive amount...
That density is the oxygen of outdoor sculpture. It is why Claes Oldenburg's 18-ft.-high red steel Geometric Mouse, Scale X looks convincing on its beach, and why Alexander Liberman's Argo is the most successful combination of work and site in the entire show. The white sails, cylinders and arcs simultaneously evoke an archaic temple precinct and a ship, while running a counterpoint to the real spinnakers billowing on the sea below; they turn a flat site, for a moment, into a reminiscence of the Aegean. It becomes increasingly clear that Liberman, along with Mark...
