Snowpack is one of the world’s most valuable resources, providing sustenance for crops and drinking water.

Science writer Ned Rozell recently returned from a trip to Costa Rica with plenty of observations on the creatures that inhabit the country and how they differ from his home.

On April 1, 1946, in the Aleutian Islands, five lighthouse tenders died in a near-field tsunami, one of the greatest and most unpredictable threats to Alaska coastal villages.

Graduate student Lauren Keller is studying the bones and teeth found at a site along the bluffs of the Colville River.

Recent columns by science writer Ned Rozell have prompted Alaska writers to send in poems based on the wildlife featured in his works.

One researcher is recording the vocalizations of the birds 24 hours a day at the landfill in Fairbanks.

While some are a recent arrival, insects have been in the state living indoors and outside for centuries.

The Alaska blackfish is different from others in the state because it can pull oxygen from free air, allowing it to occupy stagnant northern pools that kill other fish.

Earth is a giant magnet, explains science writer Ned Rozell. So the difference in the two, known as degrees of declination, changes depending on where you are.

Using supercomputers at UAF, scientists predict more than 200 glaciers will have disappeared from Alaska by 2100 under current warming trends.

Able to survive at lower temperatures than its relatives in the Lower 48, the wood frog in Alaska has shown to be even more hardy.

William Dall spent years surveying and studying the state for the Smithsonian Institution, including most of his findings in the book “Alaska and its Resources.”

One researcher’s studies found that black-capped chickadees can gain an additional 10% of their body weight each day by stuffing themselves, before using that fat to shiver all night to stay warm.

An essay included in the document reported people have found about 1 million dead seabirds on Alaska’s western coast and the Gulf of Alaska in the last decade.

Science writer Ned Rozell explains how our northernmost cities surrender to darker days in early winter only to regain light to an eventual abundance.
