Unlike most scientists, Chemist Urey believes that water-not lava-formed the smooth lunar plains and filled-in depressions revealed in photographs taken by Ranger and Orbiter spacecraft. The dark plains, he says, "look precisely like the bottoms of dried-up, primitive oceans or lakes." And material in filled-in craters and crevices may once have been flowing...
...Tails. X-ray studies reveal natural collagen as three strands of molecules twisted together like rope. The strands are short, and many have to be joined end to end to make up the body's long collagen fibers. Dr. Tomio Nishihara, a physical chemist who heads research for the Japan Leather Co., and Dr. Francis O. Schmitt of the Massachusetts Institute of Technology, thought there must be something on the ends of the basic molecules that enabled them to couple. Dr. Albert L. Rubin and an M.I.T. team set about testing the theory. They found that each collagen strand...
Such action could scarcely come soon enough. Even if Great Lakes pollution ceased immediately and completely, Chemist Robert Rainey of Oak Ridge National Laboratory reports in a recent Science magazine article, it would still take the natural flow of water through the lakes a shockingly long time to purify them. Because they are relatively shallow, Lake Erie could purge 90% of its polluting wastes in about six years, Rainey calculates, and Lake Ontario in 20 years. But Lake Michigan would need 100 years to achieve the same degree of purity, and Lake Superior would not approach its pristine state until...

Paint-Not Blood. For seven years, Miller awaited execution. Seven hours before his scheduled death in 1963, a federal judge granted him a habeas corpus hearing at which he was finally allowed to have his own chemist examine the shorts. The stains were paint-not blood. Even more startling, the state conceded that the prosecutor had known the truth during the trial...
