...test, four Air Force officers and a civilian stood unprotected on the ground below the point of explosion. They felt a hot blast, a rush of air and heard a thunderous roar, but their Geiger counters proved what the Air Force and the Atomic Energy Commission hopefully expected: the amount of radioactive fallout was too slight to endanger a city's population if a Genie exploded overhead...

Regulations must be passed that establish criteria for the amount of tar which may pass through a given filter, and require the manufacturer to state the effectiveness of the filter...

In another room in M.I.T.'s sprawling Building 2, a colleague toyed with a tray of marbles to demonstrate molecular action. Near by, another scientist was making a telescope out of cheap lenses, curtain rings, a cardboard cylinder, and some pieces of hose from a truck radiator...

The House bill exempting capital gains may be even more important, since it would benefit not only the feeders but the whole U.S. airline industry. By freeing...
