When Dr. Ponnamperuma added hydrogen to the mix in the tube, less adenine was formed, and he concluded that life could not have developed on earth until most of the free hydrogen in the earth's primitive atmosphere had escaped into space. Only then could adenine and similar chemicals have been made out of methane, ammonia and water. Gradually, those chemicals accumulated in the ocean where the first life appeared, and at last they formed nucleic acid, life's key substance...
These are only a few of the myriad new uses; man also employs the gases to fire rockets, sterilize rooms, freeze ice cream and produce soda bubbles. Food processors use liquid hydrogen to stiffen oils into shortening through "hydrogenation." Steelmakers are taking big gulps of pure oxygen in their furnaces to speed melting. In orbital flights, the astronauts burn liquid oxygen as fuel and breathe its evaporations...
Speaking in the Quincy House Junior Common Room, Teller, who strongly advocated development of the hydrogen bomb, maintained that the present U.S. security classification system does not protect the United States; "the Russians probably know all our secrets and all those we will discover in the next few years...
...years later that somebody else had had the idea before him, but had not pursued it.) Why not make use of some of the techniques of nuclear physics and inject into the patient a carefully measured dose of heavy water (D20, the oxide of deuterium, the nonradioactive isotope of hydrogen)? When the D20 and the body's ordinary water (H2O) were thoroughly mixed, the dilution of the heavy water would show the body's total water volume. All this was easier said than done; it took 2½ years to get results that satisfied Moore's meticulous...
Brookhaven-Syracuse University study last summer in Geneva. Last week experimental teams on opposite coasts of the U.S. confirmed its existence. They used two of the world's largest atom smashers, Brookhaven's Synchrotron and Berkeley's Bevatron, to fire negatively charged K mesons into a hydrogen bubble chamber. After the mesons collided with hydrogen nuclei, the scientists found two K mesons that were the decay products of an even more ephemeral particle. It has a life span of just 2/1 0,000th of a billionth of a billionth of a second-or just long enough...
