Science has itself contributed to the creation of that state machinery which now makes the enterprise of science hazardous. It has done so because it has lacked responsibility for its growth. It is too late now to fall back on the platitudes of academic freedom; no biochemist can be sure that in pursuing the structure of an enzyme he is not perfecting a lethal form of warfare...
...weapons. The canceled secret projects at Pennsylvania on chemical and biological warfare, for example, were primarily designed to find out how to protect U.S. civilians against attack from an enemy using them. "It is not safe for the U.S. to be ignorant of these powerful weapons," argues Penn Biochemist Knut A. Krieger, who directed the studies. Villard points out that secret anti-missile work is intended to help maintain the nuclear stalemate-which is the present best guarantee for peace...
...typing. Centrifuges separate out various blood components; the red cells, with glycerol added to prevent ice-crystal formation, are flash-frozen in liquid nitrogen at -320° F. Stored at this same temperature in thin stainless-steel flasks, they will keep for years. Says the center's Biochemist Arthur W. Rowe, who developed the technique: "We have taken a long step toward ending the tyranny of the 21 days...
Working with bits of bone, fossilized impressions in stone and educated intuition, scientists have cleverly deduced the appearance, weight, speed and even habits of animals that have long been extinct. Now, University of Arizona Paleontologist-Biochemist Tong-yun Ho has gained an unexpected new insight into the metabolism of many of these extinct animals. He has learned to take their temperature...
Reverse Selection. There remains the question of why the Mongols and related peoples are "yellow." Biochemist Loomis explains this on the basis of additional keratin (horny material) in the outer skin layers-though dermatologists deny this and say that the Mongol's sun screen is melanin, like the Negro's, but in smaller amounts. Loomis surmises that the yellow races may have developed their coloration after having gone through the white-race depigmentation phase. If migration away from the equator produces lighter skins, says Loomis, reverse migration could have the opposite effect. In the mere...
