Mountain snowpacks accumulate snow throughout the winter, building up stores of water that will supply communities across the American West throughout the long dry season. Now, a new study shows that as storms carry snow to the Rocky Mountains, they are also bringing mercury and other contaminants from mines in the region. The research helps scientists understand how contaminants are spread by atmospheric circulation and has implications for snowpack preservation and illuminating the lasting environmental impact of mining activities. …read more

For dogs housed at Texas kennels, age and fecal score are important factors for screening for subclinical Giardia infections. …read more

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. …read more

A new study warns that global climate change may have a devastating effect on butterflies, turning their species-rich, mountain habitats from refuges into traps. Think of it as the ‘butterfly effect’ — the idea that something as small as the flapping of a butterfly’s wings can eventually lead to a major event such as a hurricane — in reverse. The new study also suggests that a lack of comprehensive global data about insects may leave conservationists and policymakers ill-prepared to mitigate biodiversity loss from climate change for a wide range of insect species. …read more

Investigators have uncovered how resistance to chemotherapies may occur in some cancers. Researchers focused on a pathway that harnesses reactive oxygen species (ROS) to kill cancer cells. The study found that mutations to VPS35, a key player in this pathway, can prevent chemotherapy-induced cell death. These results could help pinpoint treatment-resistant tumors. …read more

Researchers have created a way to see your family tree as a movie rather than a still portrait by tracing where your ancestors moved across the globe over time. The statistical method can also be used to model disease spread and studying how animals move through geographic regions. …read more

Researchers found increased meltwater and rain explain 60% of a decades-long mismatch between predicted and observed temperatures in the ocean around Antarctica. …read more

People living with Long COVID often feel dismissed, disbelieved and unsupported by their healthcare providers, according to a new study. …read more

To encourage scientists to speak up when people misuse science to serve political agendas, biology professor Mark Peifer of the University of North Carolina at Chapel Hill argues that eugenics should be included in college genetics curriculums. …read more
