Made of wood, metal and rubber, the arm is powered by a flat, easily hidden carbon-dioxide container linked by rubber tubes to a system of tiny valves. The valves can be opened or closed by the slightest movement of the muscles over which they are placed. The opening of each valve causes carbon dioxide to spurt from the container through a corresponding tube to tiny air bellows that move part of the limb. The carbon gases escape through a special exhaust...
...gently. Some can type, use keys, write with a pen. The new arm costs between $357 and $600, including the cost of a three-to four-week course in adjustment at the Heidelberg University Clinic. Chief disadvantage: depending on how often the limb is used, the supply of carbon dioxide has to be renewed every two days to two weeks...
...Department of Agriculture announced success with a long-held dream of agricultural chemists: an insecticide that makes the whole plant deadly to insects that try to feed on it. The chemical, called Thimet for short,* was developed by American Cyanamid Co. It is mixed 50-50 with carbon dust, and 8 lbs. of the blend is mixed with 100 lbs. of cottonseed before planting.

Ford and a crew of local laborers dug deep into Poverty Point. By carbon-14 dating, they determined that the city was first settled about 800 B.C. Its gamehunting people used spear-throwing sticks and bolas (clusters of stone weights). They had a little pottery of poor quality...
...cosmic cloud were made entirely of hydrogen; there was nothing else to be made of. As nuclear reactions took place inside them, they turned partly into helium by fusion processes similar to those that generate the energy of hydrogen bombs. They also cooked up middleweight elements such as carbon and oxygen...
