Recent research on the ice worm has shone some light on the tiny creature that appears when the sun sets on warmish glaciers. Few people have seen ice worms, but they are not mythical. Wispy and less than one inch long, ice worms live on glaciers, wriggling to the surface at night and sometimes lingering in meltwater pools during the day. They seem to be dormant during the winter. No one knows...

Stronger winds and thinner ice are forcing Alaska polar bears to work harder to remain in Alaska, according to scientists who have studied increased movements of both sea ice and bears. "There's an energetic cost to stay in Alaska," said David Douglas of the U.S. Geological Survey Science Center. He and others compared wanderings of polar bears from two periods and found the bears now need to...

Millions of people live in dimples on the Earth's surface — often near the ocean, in lowlands between mountain peaks too rugged and cold. One of these global indentations, Cook Inlet Basin, recently showed another characteristic of the planet's basins — they quiver like a bowl of jelly during an earthquake. Many people in Anchorage got rattled during the recent 7.1 earthquake on January 24. Carl...

The ice floating on top of the world covers pretty much the entire Arctic Ocean in midwinter. By late summer it shrinks to half that much. If trends continue, by mid-century the summer ice may take up less space than Japan. As the Arctic Ocean becomes more blue, it absorbs much of the sun's heat that it once reflected with great efficiency. This warmer ocean would quicken the melt of the...

ST. MATTHEW ISLAND —I’m resting on a mattress of tundra plants that are growing more than 200 miles from the nearest Alaska village. While I have snuck away here to my own private ridgetop, eight other people, all scientists, are somewhere on this 30-mile-long wedge of tundra, rocky beaches, lakes and bird cliffs in the central Bering Sea. We nine make up the entire human population of the island...

A headline in the print edition of the San Francisco Chronicle catches the eye of a visiting Alaskan: Wolves feed on calf. In a Dec. 20, 2015 story, Chronicle reporter John King reported that wolves were likely responsible for killing and eating a young beef cow from a rancher's herd in northern California. It is the first reported wolf kill on California livestock since the 1920s. That was the...

U.S. Geological Survey topographic maps give you a choice on the height of Mount Isto. Depending on what map scale you choose, the mountain in the Brooks Range is either higher or lower than 9,000 feet. Using a new combination of techniques, an Alaska researcher has crowned Mt. Isto the highest peak in America's arctic, unseating longtime presumed champion Mt. Chamberlain, listed at 9,020 feet....

From space, the Nogahabara Dunes are a splotch of blond sand about six miles in diameter surrounded by green boreal forest. Located west of the Koyukuk River, the dunes are the site of an uncommon discovery. In 2001, biologists for the U.S. Fish and Wildlife Service were walking the dunes when they noticed the sand was infused with black rocks. Looking closer, they saw the rocks were obsidian,...

In this quiet, peaceful time of year, with all the noisy birds flown south and all the scary bears in hillside dens, little things catch our attention. Like wires that move as if by magic. Aurora scientist and interested-in-all-things guy Neal Brown contacted me to see if I had written about why power wires sometimes dance to their own beat when there seems to be no wind or other force pushing...

As a river eats its way into Newtok, Alaska, residents are planning their moves to a new village site 12 miles away. One family will move into a house on skis with the ability to migrate as needed with self-contained water and electrical systems. In his dozen visits to Newtok, a village of about 354 people 100 miles west of Bethel, Aaron Cooke has seen why the villagers have voted to move. "In...
