...metal-mesh enclosure that blocks out most outside electrical disturbances. As the subject chews and drinks in his static-free environment, his tooth transmitter gives out a signal every time two spots of gold on the chewing surfaces of two opposing teeth come together. In addition, a muscle-tension detector attached to the skin of his jaw is connected to an electromyograph. The signals from the chewing teeth and the muscle-tension record of the electromyograph are picked up by a receiver and recorded on tape before being translated into graphs. Some subjects have been wired for sound in their...
...detected until 1956 when Physicists Frederick Reines and Clyde Cowan Jr., of the Los Alamos Scientific Laboratory, set up a monstrous apparatus near the Atomic Energy Commission's Savannah River reactor, which looses vast floods of neutrinos. A few times each hour while the reactor was working, the detector registered an "event." This meant that a single neutrino, out of many billions of billions per second, had actually hit something...
...such explosions are far from invisible to eyes designed to see them. Most of their energy goes into X rays that travel unhindered through space and are stopped by the earth's atmosphere. A sensitive X-ray detector above the atmosphere can spot them 200 million miles away, and the satellite sentries launched last week carry twelve cylindrical X-ray detectors poking out in all directions. Inside the satellites' skins are instruments that will watch for the neutrons and gamma rays that also come from explosions in vacuum...
...compress bandage and a package of shell wound dressing. Those with the inclination can buy sextants, litters, bayonets, shoulder holsters, jungle hammocks, gas masks and policemen's billies. Central no longer sells dog sleds, as it once did, but the suspicious purchaser in the market for a mine detector is its ideal customer...
...they do on earth. The actual identification of these creatures will have to wait for larger, more elaborate spacecraft. But in the meantime, to ensure that Mars is not contaminated by earthly microbes carried there aboard the multivator, Lederberg is working on a technique for sterilizing his life detector...
