...were homeless. News of other hundreds dead trickled in from villages in the surrounding mountains. Over the course of five days, successive quakes trapped and killed rescue workers trying to dig out survivors from the first disaster. France offered a stethoscope device successfully used in Agadir in March to detect still breathing victims trapped beneath the rubble. The U.S. naval attache in Teheran flew a DC-3 down to the stricken city with emergency supplies and took out survivors. At week's end Queen Farah, who is expecting her first child this fall, offered to take 200 motherless children...

Universal Waves. Another scientist much preoccupied with the possibility of messages from civilizations outside the solar system is Harvard's Nobel Prize-winning Edward Mills Purcell, who with Harold I. Ewen was the first to detect the 21-cm. waves. If nonsolar aliens are sending messages to earth, theorizes Purcell, their first problem is to select the proper radio frequency, and their most likely choice is 21 cm., the sharpest and most universal radio waves that flash through space. Such aliens would reason that if earthlings have an electronic technology, they would know about the 21-cm. waves...

That depends on the kind of test. A test conducted on the surface of the earth or in the atmosphere is relatively easy to detect: it gives oft radiation that can be detected at great distances and in minute quantities. But special difficulties arise with tests in outer space or underground. Testing in outer space is largely a theoretical possibility, but underground testing raises troublesome detection problems here and now. Neither fallout nor radiation escapes, and the only way to detect the test is to use seismographic instruments to pick up the earth tremors. Since there is no sure...

...thought so when it entered in the Geneva conference in October 1948, but learned in the Hardtack underground test series in Nevada in September 1958 that no detection system using known methods could be depended upon to detect explosions of less than 19 kilotons...

Waiting for Bumps. Saying that CAT surrounds the jet stream does not help detect it. The stream is capricious, whipping up and down and from side to side like a shaken rope. The only way at present to find belts of CAT is to fly an airplane through a region where it may be -and wait for the bumps to begin. The Weather Bureau intends to do this if it can get the money to fly its elaborately instrumented hurricane-hunter planes during hurricane-free seasons. Such a course of flying may suggest ways to warn pilots of CAT ahead...
