Tiny particles bubbling up from the tops of melting sea ice into the Arctic sky may be a key, understudied element of cloud formation in that climate-sensitive region. Researchers from Colorado State University have published findings in Geophysical Research Letters that highlight how these airborne “ice-nucleating particles” from biological sources, such as bacteria, provide a platform […]
Weasels are small carnivores with a long body and short legs. They also have a stout skull and sharp teeth. These creatures, along with ferrets and minks, make up the Mustelinae subfamily. Until now, researchers believed that the oldest fossils from this family were from Poland and Germany, dating back to about 3.5 million […]
The history of earthquake-like signals created by the crashing of glacial ice into the ocean can reveal how a glacier has changed over time, according to research by a University of Alaska Fairbanks team. Their study focused on Alaska’s Columbia Glacier, which flows into Prince William Sound and is one of the state’s fastest-retreating […]
Researchers at the University of Alaska Fairbanks have launched a three-year effort to develop a new system to remotely detect and assess ground vehicles and low-flying aircraft, including drones. The Army Research Office is providing $500,000 in funding for the project, which is led by the UAF Geophysical Institute’s Wilson Alaska Technical Center. Scientists […]
