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 […]
Learn the art of bonsai in a hands-on class taught by longtime florist Paul Marmora in Anchorage. Marmora is past president of the Cook Inlet Bonsai Study Group. 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 […]
CHAMPAIGN, Ill. — Materials scientists can now use insight from a very common mineral and well-established earthquake and avalanche statistics to quantify how hostile environmental interactions may impact the degradation and failure of materials used for advanced solar panels, geological carbon sequestration and infrastructure such as buildings, roads and bridges. The new study, led by […]
