Time capsule: Mosquito molestation motivates minor migrations
July 13, 2026
Enough mosquitoes perch on my tent these nights that they could airlift Jane and me to their favorite bog if they all latched on and lifted at once. Fortunately, mosquitoes don't have very big brains.

Flying for science (and the occasional sled dog)
July 02, 2026
A Cessna 185 zigzagged a tight back-and-forth pattern along Alaska's southern coast earlier this summer, the pilot intent on his mission to measure the ocean's response to summer glacier melt. Alaska State Climatologist Martin Stuefer gazed down from the belly of the plane via a hyperspectral imaging camera he had mounted there.

Art-and-science exhibit depicts farming and permafrost interactions
June 25, 2026
An art-and-science exhibit explores the complexities of permafrost and its effects on farmers' lives. Installed along the path on West Tanana Drive, which parallels the Georgeson Botanical Garden, is the Permafrost Grown Art and Science Walk. This exhibit showcases art made by farmers and ºÚÁϳԹÏÍø researchers who participated in Permafrost Grown, a project studying the interactions between permafrost and agriculture.
Our large army of little green shield bugs comes and goes
June 25, 2026
The tiny flying green annoyances seemed to be more numerous than usual in late May and early June."They" are the birch shield bug, Elasmostethus interstinctus. They are native to Alaska and are about the size of a small blueberry.
A bird and a puzzling sound lead to discovery
June 18, 2026
I walked around outside our Two Rivers home early one morning, as I sometimes do. It was mid-May and we were about ready to head to work. The birds had recently returned. I heard American robins, black-capped chickadees, a ruby-crowned kinglet and a Swainson's thrush in our woods above Potlatch Creek. A raven flew over our sled dogs.
Alaska kelp farms have varied effects on marine CO2 levels

Time capsule: How to win the ice pool
June 12, 2026
One sure way to win the Nenana Ice Classic is to invest $100,800 to buy 50,400 tickets, one on each minute from about April 18 to May 22. Someone else probably will win, too, so you will probably lose money.
Week highlights work against invasive species in Alaska
June 10, 2026
Alaska Gov. Mike Dunleavy has designated the week of June 14-20, 2026, as Alaska Invasive Species Awareness Week, which highlights the work of groups such as the Alaska Invasive Species Partnership to manage invasive species in Alaska.
Salmon tagging data could help trawlers reduce bycatch
June 08, 2026
A ºÚÁϳԹÏÍø research team has translated a trove of data from a Chinook salmon tagging program into a predictive model that could help reduce bycatch by fishing trawlers. Chinook salmon range from the ocean's surface to depths where trawl nets target groundfish species. The researchers' model uses more than 700,000 data points between Southeast Alaska and the Bering Sea to predict how Chinook will be distributed across the water column. With that information, trawlers can potentially adjust their operations to reduce inadvertent salmon catches.
June 08, 2026
The ºÚÁϳԹÏÍø' Large Animal Research Station is open for the 2026 summer season. Public tours are available every day at 10 a.m., noon, and 2 p.m. Tour guests will see and learn about muskox, reindeer and wood bison.
Deep-sea expedition uncovers dozens of new species
June 05, 2026
An international team of experts discovered over two dozen new marine species on a recent expedition off the coast of Brazil in the tropical South Atlantic Ocean. The science team, which included ºÚÁϳԹÏÍø researcher Russ Hopcroft, used advanced technologies to explore the ocean's midwater, the zone between the sunlit layer and the seafloor. It can take scientists decades to identify and describe new species, but the combination of technology and expertise enabled the team to confirm 31 new species within a matter of days.
