...tiny capsule FM transmitter that can make just such broadcasts. It is small enough (|⅛in. long, 4/10 in. in diameter) to be swallowed like an oversized pill. Conceived by New York Physician John T. Farrar, the plastic-encased transmitter was designed by RCA's doughty old (67) Electronics Pioneer Vladimir Kosma Zworykin (who perfected the electron microscope) to record changes in activity in the digestive tract...

...electron microscope shows that in green leaves the chlorophyll is arranged in flat disks like piles of plates. Biologists suspected that this delicate laminated structure had something to do with photosynthesis, but they could not make sense out of it until Bell Telephone Laboratories invented its solar battery, an electronic device made of thin layers of treated silicon. When sunlight hits the battery, it knocks electrons out of one of the silicon layers. Caught by another silicon layer, the electrons turn into a useful electric current. Hearing about this principle, Dr. Calvin and other scientists speculated that the thin layers...

...meet this objection, Drs. Calvin and Sogo cooled their apparatus down to - 140°C., close to the temperature of liquid air, so that electron-yielding chemical reactions could not happen. Then they placed deep-frozen chlorophyll in a magnetic field and shot extremely high-frequency radio waves through it. When strong light was shone on the chlorophyll, some of the radio energy was absorbed. This proved to Dr. Calvin that chlorophyll exposed to sunlight contains free electrons, and is therefore capturing light energy by the layer-to-layer method. Nature's green plants. Dr. Calvin believes, have turned...
