A study released Tuesday by a team of scientists from Harvard University found that airborne radiation levels downwind of U.S. fracking sites are significantly elevated compared to background levels, providing further evidence that the drilling practice poses a threat to public health as well as the climate. Published in the journal Nature Communications, the study detected the largest […]

A volcano is like a stream. It might sound like a Zen proverb, but it’s a useful comparison for University of Alaska Fairbanks Geophysical Institute graduate student Julia Gestrich. Scientists can use stream flow to understand volcano ash plumes, Gestrich explained while presenting her research at the American Geophysical Union Fall Meeting in Washington, D.C., […]
Atmospheric scientists at the University of Alaska Fairbanks have launched an effort to better understand urban air quality problems in northern cities. During the next few years, Bill Simpson and Jingqiu Mao of UAF’s Geophysical Institute hope to join international researchers on a large-scale field study to understand the chemistry behind air pollutants in Arctic […]
