...serve as bungalow-size space stations for three-man crews. The first will include a doctor, who will study the effects on himself and his companions of 28 days under zero gravity. The crew will also try to learn how vacuum and weightlessness affect certain manufacturing processes. These include electron beam welding and the use of molten substances to fabricate extra-strong materials and perfectly round ball bearings. The astronauts' 10,000-cu.-ft. living space will feature a wardroom for relaxation, a microwave oven, a "sponge shower" with a vacuum cleaner to get rid of wastes, and even...
...steam-powered bus and police car. Lear also plans to enter a steamer in the Indianapolis 500, perhaps next year, to help get his message across to Detroit. In fact, there are signs that Detroit has got the message already. Ford has signed an agreement with Massachusetts' Thermo Electron Corp. for joint development of a small steam engine, and General Motors has contracted with Oakland's Besler Developments, Inc. to install a steam motor in a Chevrolet for testing...
Harvard physicists may be unable to initiate new research at the Cambridge Electron Accelerator next year because of the Atomic Energy Commission's failure to increase funding of individual Harvard researchers...
...Griffith, 26, was well aware that his task would be extremely difficult. The DNA molecules from the pea-plant chromosomes used in his research project were only one thirteen-millionth of an inch across and would be agonizingly difficult to distinguish even with the aid of the most powerful electron microscope. In addition, the molecules would be distorted or destroyed by the instrument's electron beam before they could be photographed. Then how could they be photographed...
...Griffith finally found an answer. Using a delicate technique that he describes as "more witchcraft than science," he began spraying his DNA samples with a thin coating of tungsten atoms. The tungsten film enhanced the outline of the complex molecule and was heavy enough to shield it from the electron beam. But it was not so thick as to obscure the molecular structure. The resulting pictures, which Biophysicist Griffith painstakingly developed himself to bring out maximum detail, show a blurred image that has been magnified 7,300,000 times. Fuzzy as they are, the pictures are clear enough to reveal...
