...post even tried a bit of Viet Cong-type cunning. Getting word that the Reds planned to cut the post's barbed-wire fence by night and stage a raid, the corpsmen lay in ambush outside the post. They allowed the Viet Cong to snip through the first layer of wire, then pelted them with hand grenades. The defenders lost one man; but the Viet Cong's 37 attackers were wiped...
Earth Movers. French Archaeologists place the ancient art work in two distinct periods. The first, Aurignacian, is roughly 25,000 to 30,000 years old, the other, Magdalenian, dates from 15,000 to 20,000 years ago. With the drawings fully authenticated (a thick layer of limy deposit, like candle wax, covers many of them, dismissing the possibility of a modern hoax), the cave is rated as a major archaeological find. Many art historians believe that cave art had magical meaning, purposely put in as cramped a space as possible in a sort of protective return to the womb. Though...
...Bible was reproduced by what Bob Chollar, the company's head of research, calls photochromic micro images, or PCMI. The film has none of the silver halide grains that are the vital element in conventional photographic film; instead there is a very thin layer of a dye that darkens rapidly when exposed to ultraviolet light. The resulting picture has no "grain." Images of Bible pages projected in ultraviolet were reduced by lenses and focused one by one on the dye. After each exposure the film was moved mechanically to array the tiny pages in close-packed rows. This miracle...
...Floods. Rain is an even greater threat than an eruption, Tazieff has warned. Only last December the flooded Reventado River pushed thousands of tons of volcanic mud onto the out skirts of Cartago, killing 13 people and wrecking hundreds of homes. Now the danger is worse. A thick layer of unstable ash has accumulated in the area between Cartago and the smoking mountain. With the rainy season approaching, it may turn into a slithery morass and, faster than a man can run, slide down the valleys, picking up rocks and trees. The first heavy rain to soak Irazú, Tazieff...
...Pont already has a thriving competitor in tiny Arnav Industries of New Jersey, which is making a roughly similar material of its own for children's shoes. Britain's Courtaulds also makes a similar material, which will not breathe but will hold moisture in an inner layer until the shoe is removed. All competing processes will have to differ substantially from Du Pont's, since the firm holds patents on just about everything but the word shoe...
