Latest CDC data show that guns now kill more children than any other cause, but health care interventions show promise for prevention Gun violence in the United States has increased to the point that it now kills more children than any other cause, including car accidents, and pediatricians may not be entirely prepared. While health […]
University of Alaska Fairbanks students will return to several Bristol Bay communities this year to continue quantifying and mapping widespread coastal erosion. Students in the Arctic Coastal Geoscience Lab of the UAF Geophysical Institute have been trudging through mud and scrambling over the debris of slumped-off bluffs in the region since 2016. Their research is […]
Alaska’s coastal waters are some of the most commercially valuable and productive ecosystems on the planet. Ocean acidification—a decrease in ocean pH caused by increasing concentrations of carbon dioxide—is expected to impact these ecosystems, but very little is known about how it could alter nearshore environments. Nearshore ecosystems provide habitat and serve as a nursery […]
Two sounding rockets are scheduled to launch from Poker Flat Research Range just minutes apart in an experiment aimed at learning how energy is transferred and dissipated during auroral displays. The findings could increase the understanding of factors affecting satellites in low Earth orbit. The NASA-funded Ion-Neutral Coupling during Active Aurora experiment could launch from […]
While running through Bicentennial Park in Anchorage, biologist Jessy Coltrane spotted a porcupine in a birch tree. On her runs on days following, she saw it again and again, in good weather and bad. Over time, she knew which Alaska creature she wanted to study. “I thought, ‘Oh my god, how does he do it? […]
Scientists find that some Pacific cod may be more vulnerable to climate change than others. Much of the success in managing U.S. fish species has come with recognizing local differences and genetic variability within species. Pacific cod are an important commercial fish species caught throughout Alaskan waters. Cod caught in the Gulf of Alaska and […]
Genes evolved under intense poaching pressure In regions of Africa wracked by heavy poaching, scientists have observed an increasing number of African elephants without their iconic white tusks, prized in the multibillion-dollar wildlife black market. But there has been no direct evidence indicating how this was happening or why this trait was occurring exclusively in […]
What if the country’s largest earthquake in the last half century happened as you were getting ready for bed in the only cabin on a tiny island in the North Pacific? What if the epicenter was just 50 miles away? A magnitude 8.2 earthquake happened at 10:15 p.m. Alaska time on July 28, 2021. The people […]
Over 35 species of rockfish live in the waters off the coast of Alaska. Rockfish have been harvested for subsistence for thousands of years, and commercially and recreationally fished since the early 1800s. Because rockfish are slow to reproduce, they are vulnerable to overfishing and require sound management to keep populations healthy. Some rockfish populations […]
