Main approach to the problem of utilization of solar energy has been study of green plants, which in their own simple and mysterious way utilize the energy of sunlight to convert carbon dioxide and water into food. Chief agent in this process of photosynthesis is chlorophyll, the green coloring-matter in leaves, which acts as a catalyst, speeding up the transformation, but undergoing no conversion itself. Since chlorophyll is not effective as a catalyst when extracted from the plant, chemists have been unable to study its action. It is composed of two separate pigments, blue-green chlorophyll A and yellow...
...this week's [July 25] swell TIME write-up of the Hughes flight was a discussion of the rubber life raft with bottled carbon dioxide for quick inflation. Carbon dioxide happens to be a bad actor as soon as it smells rubber. . . . Its rate of diffusion through rubber is about 15 times that of air. A rubber life raft inflated with carbon dioxide in mid-ocean might, for this reason, be a little embarrassing, perhaps even rather trying after a certain lapse of time...
Department of Chemical Engineering Yale University New Haven, Conn. Although carbon dioxide does indeed leak through rubber 15 times as fast as air, the leakage is still slow. A CO2-inflated raft will carry a man four to six days. CO2 is used only for the first quick inflation: the raft thereafter is kept buoyant by a hand air-pump...
Adults who have been struck by lightning (see p. 18), overcome by carbon monoxide, shocked by an electric current, or submerged under water as long as half an hour, can often be "brought to life" again. Essential treatment is immediate and continuous artificial respiration. This month's issue of the Canadian Medical Association Journal cites the case of a young lineman who was shocked by 26,000 volts, received immediate treatment by trained fellow-workmen, and after eight hours of unconsciousness began to breathe normally. "The only really safe plan," said the Journal, "is to continue efforts until rigor...
