...water in the steam, says McCabe, is "juvenile water" which comes out of the magma or the rock around it. The rest is rain water that seeps into the ground and turns to steam when it reaches hot rock. The steam contains less than 1% of noncondensable gases, mostly carbon dioxide, and no corrosive minerals. For the time being, Pacific Gas & Electric Co. will be content with a 12,500-kw. generator, but much more steam may be available. Wells drilled 30 years ago and abandoned as uneconomic have been spouting steam ever since with no loss of pressure. "Neither...
Nevertheless, the program's staunchest boosters are the companies working under its umbrella. Boston's Godfrey L. Cabot, Inc., which bought the first policy in 1948 on its British carbon-black plant, points out that an insured company gets a big boost in its credit rating. General Mills, after insuring a bean-processing setup in Pakistan, was so sold on the insurance that it made plans to insure all new foreign investments, "though we hope never to have to collect...
...lacy pattern of little round balls in the background of this week's cover is from a deoxyribo-nucleic-acid molecule model built at Manhattan's Sloan-Kettering Institute. The grey balls represent carbon atoms; blue is phosphorous; yellow is nitrogen; red is oxygen; white is hydrogen. Molecules do not look like this, of course. The atoms in them are much too small to be seen, even with an electron microscope. The pattern shown is a small part, somewhat simplified, of the DNA molecule, which geneticists now believe is the carrier of heredity and the chemical master...
...Watson-Crick model of DNA, the two spirals are made of five-carbon sugar molecules (deoxyribose), alternating with phosphate groups. The "steps" connecting the two spirals are made of four "bases" (adenine, guanine, thymine, cytosine) linked in pairs. The pairs can point in either direction, but adenine must always be joined to thymine and guanine to cytosine...
Chemical explosions (e.g., magnesium flash powder) would not do as much damage, but they would contaminate the moon in their own way. So would powdered dyes or carbon black splashed on the moon's surface to make a visible mark. Even a probe that lands gently on the moon and tells about its feat by radio (no easy trick) might carry earthside germs whose desiccated corpses would confuse later-coming biologists. Many scientists have urged that any vehicle intended to hit the moon should be sterilized inside and out before it leaves the earth...
