...troposphere, CFCs are immune to destruction. But in the stratosphere, they break apart easily under the glare of ultraviolet light. The result: free chlorine atoms, which attack ozone to form chlorine monoxide (ClO) and O2. The ClO then combines with a free oxygen atom to form O2 and a chlorine atom. The chain then repeats itself. "For every chlorine atom you release," says Rowland, "100,000 molecules of ozone are removed from the atmosphere...
...high-altitude research aircraft is not for the fainthearted. The three pilots who flew the twelve solo missions through the Antarctic ozone hole found the task grueling. An hour before zooming into the stratosphere, each had to don a bright orange pressure suit and begin breathing pure oxygen to remove nitrogen from the blood and tissues, thus preventing the bends, which can result from rapid reductions in air pressure. Once airborne, "you have to have patience," says Pilot Ron Williams, who flew the first mission. "You're strapped into a seat and can't move for seven hours...
...meat tends to be dry when heated according to instructions and tastes better cold. Either a conventional oven or a microwave can be used for heating, but a conventional oven is better for breaded pieces, which should be crisp. As for shelf life, Perdue's method of replacing oxygen with inert nitrogen gives better results, judging from two dozen samples tested. The Holly Farms chilling process requires that the cooked birds be stored at between 28 degreesF and 32 degreesF, a range not always maintained in supermarkets and home refrigerators...
...surgical plan, initiated by Rogers and Pediatric Neurosurgeon Ben Carson, combined several intricate procedures. To avoid major hemorrhaging in the brains, they proposed to drain the boys' blood supply completely and stop the hearts. To prevent the brains and other organs from starving during this period without blood-borne oxygen and nutrients, metabolic demands would be reduced to a minimum by lowering the babies' body temperature to 68 degrees F, putting them into a state of suspended animation. Because their brains are resilient, children below the age of 18 months have a remarkable capacity to recover from induced hypothermia, which...
Their interest is hardly academic. The ozone-enriched air, which stretches from six to 30 miles up, protects life on earth from dangerous solar ultraviolet radiation (UV). Although ozone, whose molecules are made of three oxygen atoms, absorbs UV radiation, even the amount that now penetrates the ozone layer can cause skin cancers and has been linked to cataracts. With less ozone, these disorders will increase; with no ozone at all, the UV could be deadly. Scientists have long suspected that decomposing CFCs in the stratosphere release chlorine, which acts as a catalyst, breaking ozone molecules apart...
