A pair of UAF engineering students will try to collect samples every 2,000 feet on Denali, in an effort to determine if the tiny plastic particles are as abundant there as they are elsewhere on Earth.
Researcher Ben Jones found working tools — several paddles and a spear with a stone tip — within the Lost Jim Lava Flow on the Seward Peninsula.
When the ice retreats it causes them to fragment into smaller bodies of ice, establishing more glaciers.
Astrophysicists Lindsay Glesener and Sabrina Savage wait for the conditions to be ideal before launching a pair of rockets loaded with testing instruments into the atmosphere.
Researchers want to use the ultrafine rock particles left by eroding glaciers to suck climate-warming carbon from the air.
Kunali was delivered from the Alaska Zoo in Anchorage to Fairbanks, where its skin, tissue and bones will aid scientists in the future.
An expert in space physics at the UAF Geophysical Institute, Peter Delamere finished third in the Iditarod Trail Invitational 350 bike race.
In the far north, where night will soon be in short supply, nocturnal animals like flying squirrels and owls need to go about their business in daylight.
None of the four members of the Salty Science team had rowing experience, but they managed to win the World’s Toughest Row women’s division after crossing more than 3,000 miles of ocean.
A wide-ranging research program led by a UAF ecologist is tracking the way beavers’ northward movement affects permafrost, water quality, fish, birds and communities.
One Alaska geologist’s explanation: With a lack of the freeze-thaw process that other mountains experience, Denali doesn’t erode as quickly as others.
The first ice-free days of the Arctic Ocean could occur as soon as the 2020s or 2030s — as many as 10 years earlier than previous projections.
A new analysis of nearly 25,000 fish scales offers more evidence that the millions of pink salmon churned out by Alaska fish hatcheries could be harming wild sockeye salmon populations when they meet in the ocean, according to the scientists who authored the study.
Water covering a trail known as aufeis happens because underground springs pump water toward the surface no matter how cold the air above.
Most are on or near volcanoes, with very hot water bubbling or steaming up from deep below, where Earth’s great crustal plates are grinding past one another.
Because most Alaskans are now using home tests to check for COVID-19, wastewater monitoring has become a key way to measure the spread of the virus.
The magic number is minus 30: That’s the Fahrenheit temperature threshold at which air is cold enough for ice fog to form.
The oranging of northern rivers seems to be related to recent permafrost thaw that has allowed streams to release previously captive iron, trace metals and acid.
A Kenai Peninsula man died in January of the virus that until now had resulted in mild symptoms and only been detected in Interior Alaska.
Three tribal governments and the Center for Biological Diversity plan to sue to stop the project, which they say could lead to more commercial bottom trawling.
Discovery of tiny bits of plastic in the muscles, blubber and livers of Pacific walruses adds to evidence of pollution’s spread through the world’s oceans.
A recent cold snap has left temperatures across the state in the negative double digits and even as cold as minus 50 degrees.
Volcanic features near Healy are within a region scientists have named the “Denali Volcanic Gap,” reflecting a puzzling absence of volcanoes from Mount Spurr to the Wrangell Mountains in eastern Alaska.
