...months the world's most powerful particle accelerator (or atom smasher) was at Geneva, Switzerland, generating a beam of protons with up to 28 Bev (billion electron-volts) of energy. Last week the energy championship came back to the U.S. At Brookhaven National Lab oratory, Long Island, the new alternating gradient synchroton, which scientists call AGS, was kicked up to full power for the first time, generating a proton beam that stayed steady at 30 Bev and hovered for short periods as high as 31 Bev, accelerating particles at rates only a fraction below the 186,300 miles...
...will help produce an eight-part series on viruses, promising money in the bank as well as prizes. The cast: Nobel Prizewinner Wendell M. Stanley, director of Berkeley's Virus Laboratory, his top aides, and as many life-and-death-affecting organisms as they can film through an electron microscope. These wonders will not be confined to loyal locals who keep KQED going 40 hours a week. KQED will sell the films to the National Educational Television and Radio Center to distribute to 43 ETV stations across the country...
...Electron Cutter. United Aircraft Corp.'s Hamilton Standard Division (propellers) will put on the market a machine, developed by West Germany's Carl Zeiss Foundation, that uses electron beams to weld, mill and drill hair-fine holes in the hardest known materials, e.g., quartz, tungsten, zirconium. An electron gun fires beams that boost the temperature on the surface of the material up to 11,000° F. ; it can cut 100 holes in a straight line across a pinhead, drill a sapphire watch bearing in six seconds, weld a tough nu clear reactor core. Lease price: about...
Through the use of the electron microscope and X-ray microscopy, scientists at the School of Dental Medicine have observed the nature of certain dental tissue changes which give a fairly accurate estimate of an individual's age by examination of single teeth...
According to John Nalbandian, research fellow in dental medicine, the study centered on changes in the degree of transparency in the dentin or solid portion of the root of the tooth. When examined beneath the electron microscope, thin sections of dentin showed an accumulation of minerals from which the age of the individual could be determined within an accuracy range of 7.9 years...
