...aorta's arch, just above the heart, are subject to the same types of disease as other major arteries, and they should, insisted Houston's famed surgeon Michael DeBakey (TIME, June 22, 1959), be treated the same way. If the disease is true hardening of the middle layer of the artery walls, surgery can do nothing about it. If the disease is atherosclerosis (not hardening, but clogging with fatty material), affecting only a short stretch of the ascending carotid or vertebral arteries, the knife can be used with high hopes of success...
...aneurysm.) Then, using an artist's airbrush, Selverstone sprays the aneurysm with a mixture of plastics that combine to form a coating similar to Saran Wrap. This is tough, but too thin to give full protection against further leakage or bursting. So he sprays on a second layer, of epoxy plastic. The result: enclosure of the aneurysm in a capsule far tougher than the natural artery wall...
...March for Causes. For better or for worse, Suburbia in the 1960s is the U.S.'s grassroots. In Suburbia live one-third of the nation, roughly 60 million people who represent every patch of democracy's hand-stitched quilt, every economic layer, every laboring and professional pursuit in the country. Suburbia is the nation's broadening young middle class, staking out its claim across the landscape, prospecting on a trial-and-error basis for the good way of life for itself and for the children that it produces with such rapidity. It is, as Social Scientist...
...cone and warhead would have to crash back into the earth's atmosphere at near-meteor speed of 15,000 m.p.h., with enough motion of energy to vaporize five times its weight of iron. Piling up ahead of the re-entry body would be a high-pressure air layer reaching up to 15,000° F.-about 1½ times as hot as the sun's surface. But beyond that, the physical properties of air at such speeds and temperatures were almost entirely unknown, and no existing wind tunnel was fast enough to furnish the necessary data. Kantrowitz...
...contrary proved to be the case. Dr. H. Julian Allen of the National Advisory Committee for Aeronautics argued conclusively that a blunt nose was better for the heat-sink cone. The snub nose, said Allen, would help pile up in front of the cone a high-pressure layer of air that would itself act as a potent insulator. That way, most of the immense heat would be swept off the edge of the cone into a long tunnel...
