Trial Dip. The cramped (141 cubic foot) space inside the steel-shelled coconut will be crammed with control apparatus, batteries and instruments. The bathyscaphe will carry enough oxygen to keep two men alive for more than 32 hours, and chemicals to absorb the carbon dioxide given off by their breathing. Powerful searchlights outside the cabin will light up the sea, and allow fish and other bathyfauna to be observed and photographed. Because time for note-taking will be short, a recording device will bring back a running commentary on the dive. The depth ship's experimental compass will...
When circulation to the cortex is impeded, the blood bypasses the cortex and flows through bigger blood vessels in the kidney's medulla or interior (see cut). The cortex, starved for blood and oxygen, deteriorates. Results: 1) the production of urine slows or stops altogether; 2) the anemic cortex apparently secretes a substance (perhaps a hormone) that raises blood pressure throughout the body...
Moments of Greatness. How well had it done? The first Republican Congress in 16 years had done its work in an atmosphere supercharged with politics. With a Democrat in the White House, partisan issues flared up like matches burning in oxygen. The Both had committed its share of sins, and demonstrated the normal leaning of Congress toward mediocrity. It also had had moments of decision, restraint and even greatness...
Sample smash: an arsenic atom (atomic weight: 75) had 21 particles knocked off by a single blow, and was reduced to radioactive cobalt (atomic weight: 54). When the new cyclotron bombarded an oxygen atom (atomic weight: 16) with neutrons, the light atom split into five pieces (see cut; the arrows point to the five-way split of the oxygen atom, the streaks indicate the path of atomic chips...
Noise & Bumps. Besides the natural air hazards (bumpy air currents, bad weather, lack of oxygen at high altitudes), the airplane itself is a menace to health, McFarland thinks. Scientific tests have shown that the modern plane cabin is almost as noisy as a subway train. On a long flight, McFarland reports, noise can increase fatigue, inefficiency and irritability to the danger point. There is no proof, he says, that constant flying permanently deafens airmen, but it does reduce their hearing in the higher frequencies (a deaf spot known as "aviator's notch"). The plane's vibration also...
