Powerful Pinch. To attach the arm, Dr. Vert Mooney and his colleagues inserted three "buttons" or fasteners through the skin in the stump. (The buttons can permanently protrude through the skin without promoting infection because they are coated with pyrolytic carbon,* which Mooney says forms an antibacterial seal.) The doctors connected two of the buttons to the arm's median and ulnar nerves with stainless-steel coils, and wired the third button to another carbon plug that serves as a ground. They then connected all buttons to wires in the prosthesis itself, linking them to sensors in the hand...

...Venus with eight separate unmanned spacecraft-three American and five Russian, including two Soviet landing vehicles-scientists are now certain that De Fontenelle's Eden is, in fact, more like Dante's Inferno. Its surface temperature is a hellish 900° F. Its atmosphere, consisting largely of carbon dioxide, is at least 90 times as thick as the earth's, producing crushing surface pressures of 1,500 Ibs. per sq. in. Its clouds are laden with sulfuric acid. Yet a major mystery remains: Why has a planet so like the earth in size, mass and density evolved...
...thirds water, the rest nitrogen, carbon, calcium and a myriad of other chemicals-worth only about $5, even at today's inflated prices. That is the strange machinery of the human body. It appears in unprecedented and almost incredible detail this week on the Public Broadcasting Service (see facing page). Produced by the National Geographic Society and Wolper Productions, created by Irwin Rosten and narrated by Actor E.G. Marshall, the hour-long film is entitled, naturally enough, The Incredible Machine. It uses microscopy, X rays and telescopic lenses tiny enough to penetrate the body's innermost recesses...
...packaging firm of Coloroll, Ltd., is producing plastic bags that will decompose naturally in five years. The secret: addition of clean, dry starch to plastic polymers. "By putting in the starch," explains Inventor Gerald J.C. Griffin, a teacher of plastics technology at Brunei University, "we are adding carbon, hydrogen and oxygen. The bags will act as a carbon source for soil bacteria, breaking down into humus and carbon dioxide." Griffin's process, which can be used for most plastic products, has a powerful appeal beyond reducing long-lived litter. Because starch costs much less than polymer plastics, the process...
