Tiny particles in Arctic ponds may play role in cloud formation, climate change

  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 […]

A fossil of a new carnivoran species effectively doubles the evolutionary history of the weasel family

A fossil of a new carnivoran species effectively doubles the evolutionary history of the weasel family

  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 […]

Project will use air pressure waves to remotely detect vehicles, aircraft

  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 […]
