The rise and fall of acid rain is a global experiment whose results are preserved in the geologic record. By analyzing samples from the Greenland ice sheet, University of Washington atmospheric scientists found clear evidence of the U.S. Clean Air Act. They also discovered a link between air acidity and how nitrogen is preserved in […]
Scientists are facing a number of barriers as they try to develop circuits that are microscopic in size, including how to reliably control the current that flows through a circuit that is the width of a single molecule. Alexander Shestopalov, an assistant professor of chemical engineering at the University of Rochester, has done just that, […]
WEST OF NUIQSUT — A sick snowmachine awaits rescue here on the snow-covered ice of this boot-shaped lake. After an 85-mile journey from our last stop at Umiat, one of the Ski Doo Skandics sputtered to a crawl a few miles from our intended campsite here. The loss of one of their essential research tools […]
Eyal Saiet’s job is looking for the sweet spot—that connection between machine and science that makes sense. For instance, Saiet is thinking of flying an unmanned aircraft through the blow of a surfacing bowhead whale to collect mucus samples. The samples will tell biologists the health, sex and fertility of the migrating behemoth returning to […]
