...much of a predictor, is a smart detective. It can usually reveal whether a heart has been damaged, and with these clues the cardiologist can prescribe care and treatment for patients who seem to run the greatest risks of heart attacks. Yet the electrocardiograph has identified only a fraction of the nation's ailing hearts...
...helpful in aligning jet-plane assembly operations and the two-mile-long Stanford linear accelerator. When the high energy of laser light is concentrated on a small area, it serves as a high-speed drill that can burn precision holes through materials as hard as diamonds in a small fraction of the time required by conventional methods. It can vaporize the rough edges of such microscopically small products as integrated circuits. A less powerful laser beam can weld wires and other delicate metallic parts without damaging nearby heat-sensitive parts...
...after five years of testing, a new blood extract called RhoGAM has arrived on the market. It enables doctors to protect each subsequent child by merely inoculating the mother. RhoGAM consists of a gamma-globulin fraction rich in Rh antibodies. Injected into the Rh-negative mother's bloodstream no later than three days after a miscarriage or the birth of her first Rh-positive child, it curtails her immune mechanism's production of antibodies and lessens the danger to future Rh-positive children. The inoculation must be repeated after each miscarriage or birth, but the tests show that...
...rapid-transit spur that will convey travelers by train from downtown to Hopkins Airport. New York is similarly experimenting with buses that can go part of the way to Kennedy by rail. Most cities, however, are unimpressed by fixed-route service, since downtown passengers are now only a fraction of the total. The remainder reach the airport from the suburbs or surrounding towns, and the only realistic way to service them is to build still more expressways wide enough to avoid the slowdowns that cause passengers to be caught in traffic jams when their airplanes are taking...
...objects on display are only a fraction of Coolidge's acquisitions. The rest, like 3/4 of the objects the Fogg owns, are never shown to the public. Sculpture fragments, torn paintings, forgeries and most prints and drawings are stored in the basement and print and drawing rooms and are used only for study and instruction. Many large bequests of miscellane- ous art must be attributed and sometimes restored before the works which are good enough to be exhibited can be separated from those which...
