American Nuclear Society Meeting The American Nuclear Society held its winter meeting, November 26 to 28 in Washington, D. C. Concurrently, the Atomic Industrial Forum held its annual conference; and the AtomFair, sponsored by both organizations, pre sented exhibits from over 85 industrial and governmental concerns. Some of the new instruments applicable to neu tron activation analysis and related techniques, exhibited at the fair, are mentioned in the New Products section of this issue. A broad range of fields was covered by about 260 papers related to the peaceful uses of atomic energy and presented by scientists from this coun try and abroad. Especially notable were papers on the use of radioisotopes in studying problems on earth and in space. Radioisotopes, used to trace surface water, measure stream flow, study underground water circulation, determine the speed and drift of seafloor current, and estimate the amount of water needed for a given unit of electricity in hydroelectric power were discussed by original contributors. The application of radioisotope techniques to air pollution studies, determination of elements on the moon's surface, and detection of microorganisms on other planets was included in sessions related to space problems. There were also seven papers on nuclear activation analysis in forensic science. The ex treme sensitivity and accuracy of these techniques make them especially use ful in many aspects of crime detection. Technical information on this meet ing is available in a paperbound book ($7), "ANS Transactions," Vol. 5, No. 2, dated November 19, 1962. For this book, write to Octave DuTemplc, 244 East Ogden Ave., Hinsdale, 111.
Teaching Microscopy A symposium on "Teaching Micros copy in the Courses Making Use of It," sponsored by the New York Mi croscopical Society, will be held at the American Museum of Natural His tory, 77th St. and Central Park West, New York City, February 1 and 2. Sessions will meet Friday evening and Saturday morning and afternoon. Reg istration is $2. While the sympo sium consists of invited speakers, the purpose throughout is to promote dis cussion, questions, and answers from the floor. Further information is avail able from Dr. T. G. Rochow, Cyanamid Research Laboratory, 1937 W. Main St., Stamford, Conn.
