Synchrotrons in the U.S. and Europe are also helping to provide new leads for finding drugs to combat anthrax, a significant threat as an agent of biological warfare and terrorism. "These recent examples of important and diverse applications of synchrotron science underscore the exciting research opportunities that will be available to scientists at the Canadian Light Source (CLS), Canada's first synchrotron now being constructed on our campus," said University of Saskatchewan President Peter MacKinnon. A synchrotron acts like a gigantic microscope that generates intense beams of brilliant light to view the microstructure of materials. The U of S-owned CLS national facility will begin operations in January, 2004. (For information on the CLS, visit www.cls.usask.ca ) Identifying Airborne Pollutants The U.S. Environmental Protection Agency has enlisted a University of California, Davis research group to help monitor the composition and movement of smoke and dust particles from the World Trade Center excavation site. To detect rarely measured, very fine and ultra-fine (to 0.09 microns — one micron equals one one-thousandth of a millimetre) particles that can lodge deeply in the lungs, the Advanced Light Source (ALS) at the University of California Berkeley Lab will be used to analyze the air samples. The first set of results is expected by mid-November. "Details about the composition of these airborne particles should help authorities determine what safety measures are needed at the site, the length of work shifts, and whether workers need better measures to control the dust to protect local residents," states an Oct. 31 ALS users’ newsletter. Since October 1, a monitoring device on the roof of a building downwind from ground zero has been collecting air samples. In early November, the first batch of samples will be shipped back to California for analysis.
