...detergent plant in Newcastle suffered from asthmatic symptoms and skin irritations. Some dermatologists agree that enzymes, which split the proteins of stains made by chocolate, blood, gravy and other materials the way the stomach decomposes food, might also break down the skin's fatty protective layer and cause inflammation, cracked skin and swelling.

The Home Office two weeks ago announced a preliminary study of hospitals to determine whether...

...puzzle. Refining a rough idea suggested a generation earlier, Hess proposed that the earth's mantle is really a giant convection system. Like hot air in a room, he suggested, material heated by radioactive elements in the earth's interior slowly rises out of a relatively fluid layer of the earth's mantle called the asthenosphere. This lava surfaces at the mid-ocean ridges; hence, the higher water temperatures. As it flows away from the ridges, it hardens into a more rigid layer called the lithosphere. When new lava oozes out, it attaches itself to the older...
