Learn about snow physics and how snowdrifts form — and why it is possible to walk on a snowdrift – in a statewide webinar hosted by the University of Alaska Fairbanks Cooperative Extension Service. During “Catch the Drift: Measuring Snow and Water Equivalent,” participants will learn how to measure snow depth and calculate snow-water equivalent […]
Scientists are using samples from subsistence-harvested bearded seals to establish kin relationships (parent-offspring, siblings) and to produce population estimates. In its first application in Alaska, researchers are using close-kin mark-recapture methods to estimate the size of the bearded seal population. Close-kin mark recapture methods were developed by Commonwealth Scientific and Industrial Research Organisation (CSIRO) Marine […]

All materials, including trees, will be provided in this two-day workshop, hosted by the University of Alaska Cooperative Extension Service. Participants will leave with their own miniature […]
Exhaled breath contains chemical clues to what’s going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses — and improve patients’ prospects. In a study in ACS Sensors, researchers report developing ultrasensitive, nanoscale sensors that in small-scale tests distinguished a key change in […]
