Freshman Kerry Kartsonis and Wideroff broke free to challenge the Huskies defense in the second half, and fellow first-year Katherine Sheeleigh closed the door on the squad with her first goal of the season, a laser from 25 yards out that found the top-right corner of the goal...
...damage that killed the shuttle Columbia in February 2003, when superheated gases generated during reentry entered the ship through a breach in the insulation. Ever since then, astronauts have given their spacecraft a close visual inspection upon reaching orbit to look for any troublesome chips. On Sunday, a 3D laser imager attached to Endeavour's robotic arm revealed what could be a nasty...
...study will have you thinking twice about waiting for those printouts - not for the sake of the paper, but for your health. In the small study, published in the Aug. 1 issue of Environmental Science and Technology, researchers found that nearly 30% of the 62 printers they tested - including laser printers from Canon, HP, Toshiba and Ricoh - emitted high levels of ultrafine toner particles, which were potentially as hazardous as cigarette smoke. In one Brisbane office, the authors found, the concentration of particulate matter per square inch was five times higher during working hours than nonworking hours, and about...
...high-level emitters." Emissions, researchers found, were printer-specific and fluctuated depending on the age of the toner cartridge and the amount of toner a document required. It was unclear exactly what mechanism dispersed the particles into the air, but researchers think it had to do with how laser-printer cartridges access and use dry toner or with the printer's mechanical abrasion, wear and age. It's likely that different printers emit particles in different ways...
...done any recent research on the health effects of printer emissions - Morawska's study is the most extensive to date - but Sharon Worthy of the U.S. Dept. of Labor says "historically laser printers have presented no known hazard in the workplace." But, according to the Washington-based nonprofit Environmental Working Group, which has conducted research on particulate pollution from automobiles, printers release the same type of fine particles that cars do. "What we need are standards up front so that the pollution we're subjected to don't pose health risks," says Jane Houlihan, the nonprofit's vice president...
