Change in the Morning. In a way that scientists still do not fully comprehend, the pigment changes its chemical structure when red light hits it. As long as the red light lasts, the new structure persists. When the light dies, the pigment begins slowly to change back to its original state, a process that takes roughly twelve hours. Thus, when the red rays in the morning sun strike a leaf, the light-sensitive pigment changes into its new state and stays that way until sundown. This tells the plant, in the chemical language to which it responds, how long...
...year history of radio, man has learned to send signals over mountains, across oceans, and up to the moon and back. But the search for a radio that could transmit signals beneath the water's surface was sterner. To receive messages in World War II, subs had to surface or poke up the antenna-bearing periscope and risk detection. Last week word leaked that the U.S. Navy has whipped this underwater communications problem...
...January 1961, the new station will operate on a very low frequency band (14 to 30 kilocycles), sending out radio waves up to one mile long audible to surface ships and shore stations around the world. It may be utilized experimentally to try out the new Tepee scatter-back system for detecting missile firings in Russia. But specifically, it should be capable of sending orders to subs operating under the surface of the North Atlantic and Arctic Oceans. The Navy says that the signals will reach "deep down." Best estimate is that they will penetrate more than...

The accent is on youth...
Each morning Dr. Sills is up at 6:45, visits his patients in the Americus hospital, is back for office hours in Plains by 9. Says he: "I average 15 to 20 patients a day, and have worked every day since I came here. We try to close for lunch at 12, but we never can-something always comes up. At night I go back to the hospital and make house calls. The big need around here is for house calls, and I make two or three a day.'' Dr. Sills charges $3 for an office visit...
