Every 15 miles another team measures the strength of gravitation, which gives clues about the earth's crust deep under the ice. Every 30 miles seismologists bore a hole in the ice and explode a charge of dynamite. Waves from the explosion travel to the bottom of the ice and into the rock beneath it. At each boundary between ice and rock or between layers of different rock, some of the waves are reflected up to the surface, and when they are recorded by the proper instruments they tell the scientists what they have found under the mile-thick...
...great saucer of rock with a center near the Pole pressed down by the weight of ice that it carries. The thickness of the icecap will tell how much water is locked up in it, and how high the oceans stood during geological ages when the earth's Poles were ice-free. Perhaps the precious data brought back by the Fuchs expedition will explain the seams of coal in Antarctic mountains. Coal is the remains of lush vegetation, and nothing except a few hardy lichens and mosses grows in Antarctica now. One theory is that Antarctica had a tropical...
...deadlines neared for U.S. morning papers, A.P. aimed even higher, wider and wilder. Said its night lead, still without any confirmation: "Soviet Russia has shot a man-carrying rocket 186 miles into the air and the man parachuted safely back to earth, reliable sources said tonight." The A.P. noted in the third paragraph that there had been "no official announcement whatever," but added: "The official silence-in view of the rumors sweeping Moscow-led to some speculation that ... the manned rocket experiment may not have been a total success...
...Russia may have launched a moon rocket." European radio stations, said U.P., had picked up a "mysterious beep-beep-beep" which lasted three times as long as the signal from an orbiting Sputnik and "suggested the Doppler effect* that would be produced by a transmitter speeding away from the earth...
...have it within our power to eradicate from the face of the earth that age-old scourge of mankind: malaria." So said President Eisenhower last week in his State of the Union speech (see NATIONAL AFFAIRS). By latest estimates, two-fifths of the world's 2.6 billion people are subject to the disease; each year 200 million suffer from malaria, and 2,000,000 to 2,500,000 die of it. In the 60 years since the discovery that the disease is transmitted by mosquitoes of the genus Anopheles, men of medicine have had periodic fevers of hope about...
