Analysis of 2025 Tracy Arm Fjord megatsunami suggests routes for earlier event detection

Analysis of 2025 Tracy Arm Fjord megatsunami suggests routes for earlier event detection

  Early in the morning of August 10th, 2025, a large landslide triggered a massive tsunami in the Tracy Arm Fjord in Alaska – a place frequented by tour boats and commercial cruise ships. In a new analysis, researchers show how this event unfolded and highlight both the growing hazard from similar events and the […]

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

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 […]
