As polar bears adapt to a warming Arctic—a frozen seascape that cleaves earlier each spring—they may find relief in an unlikely source: snow goose eggs. New calculations show that changes in the timing of sea-ice breakup and of snow goose nesting near the western Hudson Bay could provide at least some polar bears with an alternative source of food. This new analysis appears in Polar Biology.

Farming of fish in ocean cages is fundamentally harmful to wild fish, according to an essay in this week's Conservation Biology.

A study in the Dec. 15 issue of the Journal of Clinical Sleep Medicine is the first to show the full clinical picture of comorbid conditions associated with obstructive sleep apnea (OSA), quantify their frequency of occurrence and reveal their possible interrelationships.

Researchers in a University of Oregon lab have shed more light on the mechanism that regulates DNA methylation, a fundamental biological process in which a methyl group is attached to DNA, the genetic material in cells of living organisms.

Researchers have created a new family of fluorescent probes called hydrocyanines that can be used to detect and measure the presence of reactive oxygen species. Reactive oxygen species are highly reactive metabolites of oxygen that have been implicated in a variety of inflammatory diseases, including cancer and atherosclerosis.

A new study uncovers 11 gene variants associated with three blood lipids measured to determine cardiovascular disease risk: low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) and triglycerides. The discovery opens up new opportunities for nutrigenomics researchers looking for links between diet and genetics that will optimize health and lower chronic disease risk.
