Reacting with sunlight and other common air contaminants, nitric oxide forms ozone, a chemical which closes part of the lungs and forces an animal to use more energy to get enough oxygen. Middleton showed other experts at a two-day conference at the New York University School of Medicine last week how ozone "in the quantities you commonly find in New York city air" slows down rats and mice when they exercise on a treadmill...
...spitting a 150-ft. tail of flame, Saturn 1B burned for 2 min. 26 sec., at which point it was 35 miles up and moving at 5,400 m.p.h. Next came the tricky second stage, a single 225,000-lb.-thrust engine powered by an exotic combination of liquid oxygen (lox) and liquid hydrogen (LH2). While lox boils off at a difficult -290° F., LH2 boils at -423° F., thus requires extreme pressurization to keep cool. Moreover, in weightless space, LH2, like mercury, tends to gather into a ball or spin off into tiny globs; simply to feed...
...caught in the middle, lost out. Since the Basin was designed promarily for recreational purposes the lock in the dam has to be opened--more frequently now than ever--for motor boats. Each lock-opening admits salt water, and the wedge of salt that gets into the basin prevents oxygen from circulating throughout the water to treat the sewage. And so the Charles remains polluted...
...Thermo-pollution does not present very great dangers to public health, but it does affect the wildlife in the river. It involves the with-drawal of water from the river, its circulation through a plant or building (a process which often raises the water's temperature and changes its oxygen content) and its discharge back into the river. The changed character of the water can mean increased growth of bacteria and algae, as well as death to fish...
...coronary artery disease, fewer than 10 million have their problem neatly confined to a plug of fatty or chalky material in a single artery -what doctors call "segmental disease." The majority have a diffuse disease involving several artery branches, vastly complicating all efforts to boost blood flow to the oxygen-starved heart muscle. Because there is as yet no proof that medical treatment with diet, drugs, exercise and control of weight and blood pressure does much good, Santa Monica's Dr. James A. Mc-Eachen told the American College of Cardiology, countless victims may eventually turn to the surgeon...
