Scientists have sketched out one of the greatest baby booms in North American history, a centuries-long “growth blip” among southwestern Native Americans between 500 and 1300 A.D. It was a time when the early features of civilization–including farming and food storage–had matured to a level where birth rates likely “exceeded the highest in the world […]
University and government scientists are embarking on a collaborative research expedition to improve volcanic eruption forecasting by learning more about how a deep-underground feeder system creates and supplies magma to Mount St. Helens. They hope the research will produce science that will lead to better understanding of eruptions, which in turn could lead to greater […]
This spring, John Yarie learned of the death of the oldest living things he knew. Since 1988, the silviculture professor at the University of Alaska Fairbanks had measured and fertilized a stand of giant spruce trees on a hillside south of Fairbanks. A few weeks ago, forest technicians visited the site and found that one […]
National Science Foundation- (NSF) funded researchers at the University of Washington have concluded that Antarctica’s fast-moving Thwaites Glacier will likely disappear in a matter of centuries, potentially raising sea level by more than a half-a-meter (two feet). Data gathered by NSF-funded airborne radar, detailed topography maps and computer modeling were used to make the determination. […]
