At least 12,700 of the 12-pound predatory birds migrate to the state each summer in order to create new golden eagles.
Science writer Ned Rozell reflects on what he’s grateful for, both personally and professionally.
Making the most of an opportunity to view the northern lights takes some planning, but the payoff is worth it.
The whales use clicks for echolocation just like bats, whistles for short-range communication and repeated calls that are unique to a group.
All the requirements for sea ice growth, like colder surface temperatures and sustained northern winds, came together this year in the Bering Strait region, said Alaska climatologist Rick Thoman.
The glacier advanced just over 3.5 miles and moved about 65 feet per day earlier this year. Studying the surge involved a massive undertaking.
A bar-tailed godwit tracked by scientists flew 1,200 miles before hitting headwinds and turning back to Alaska. Last week it finally made it all the way to New Zealand.
Mudflats around a 15-mile string of sand shoals near the mouth of the Kuskokwim River host nearly the world’s entire population of bar-tailed godwits in fall.
The famed “Magic Bus” from “Into the Wild” is being preserved at the University of Alaska’s Museum of the North.
Called yedomas in Russia, the mounds of land are much more populous there.
It’s the first time since 2005 that the icebreaker has traversed the Northwest Passage, which consists of several routes that — as sea ice has declined in recent decades — have become more accessible.
Red auroras are uncommon because they require a perfect mix of heavenly conditions.
A fireball, the result of those rocks breaking through the atmosphere, was spotted by many in the state in late September.
Scientist Hector Douglas has been using brightly painted decoys to study the seabird’s inviting color palette.
In the fall, trees and plants respond to fewer hours of sunlight by changing color before falling to the ground.
A CDC team is using samples of voles and squirrels to try to garner information about the enigmatic Alaskapox virus, with the first human case identified in 2015.
Scientists earlier this summer made a rare sighting of two pairs of North Pacific right whales, noteworthy because only about 30 of the massive, endangered animals are thought to remain in the waters off Alaska.
How the virus is contracted and how long it’s been around still remain a mystery. But researchers have found evidence in small mammals.
After a mishap, science writer Ned Rozell and his spouse managed to get their pliable Royalex canoe back into shape to finish their Delta River float.
Last of three parts: For both summer and fall chum, around one-tenth of the normal numbers of fish were tallied. The impacts have been extreme but causes elusive.
