Local merchants could no longer let their fingers do the walking. "I drove to 30 offices the other day to post a new listing," moaned Real Estate Broker Marge Novak. To cope with municipal business, Hinsdale Village Manager Ron Ruskey installed a cellular phone in his briefcase. Eight police cars with two-way radios were posted to permanent stations around town to help residents report emergencies. When students realized that attendance officers could not call home to check up on them, Hinsdale schools reported a sudden surge in truancies. Patients found they could not call their doctors, and the emergency...
Upon meeting a virus, the macrophage, which moves about, amoeba-like, on long cellular extensions known as pseudopods (false feet), does more than just ingest the intruder. It has another, even more important function. On its surface, like virtually all body cells, the macrophage carries MHC (for major histocompatibility complex) molecules, protein badges that enable other immune cells to recognize the macrophage as friend, or self, and not attack it. After digesting the virus, the macrophage proudly displays strips of protein from the virus in the grooves of some of its MHC molecules. Once a bit of protein -- which...
...week. He has been too busy snapping up stocks that he considered well worth buying at their depressed postcrash prices: Goodyear, Chrysler, Intel, Texas Instruments, Carnival Cruise Lines and Toys "R" Us, along with companies that most people have not yet heard of, such as Metro Mobile CTS, a cellular phone system, and Comcast, a cable-TV operator...
...personal spending grew 21% between 1980 and 1986, while disposable income during that period rose only 17.6%. One reason is that consumers cannot seem to keep up with all the shiny new temptations. Never before have they been offered so many innovations to make life easier or more comfortable: cellular phones, cappuccino makers, home computers, hot tubs, Nautilus machines, camcorders, stereo TV sets, trash compactors, snow blowers. Giving in to impulse buying is easier than ever. The outlets are ubiquitous: shopping malls, mail-order catalogs, toll-free numbers, home-shopping networks, direct mail. Even a consumer's credit card bill...
Tonegawa proved that cells accomplish the Herculean task of making antibodies to order by reshuffling parts of the genes that govern the production of antibodies, the cellular building blocks of the immune system. He likens the process to rearranging the boxcars on a freight train. "The dogma was that the order of the genes in any one person is immutable," he says. "The freight train never shifts its cars around." In spite of prevailing theory, Tonegawa found that the "cars" did indeed rearrange themselves in a multitude of different configurations to make the antibodies that fight off diseases. His work...
