Counties in Pennsylvania that contained or were near cultivated cropland had significantly higher melanoma rates compared to other regions, according to a new study led by scientists at Penn State.

Amouse study led by University of California, Riverside biomedical scientists suggests that everyday exposure to microplastics — tiny fragments shed from packaging, clothing, and countless plastic products — may accelerate the development of atherosclerosis, the artery-clogging process that leads to heart attacks and strokes. The harmful effects were seen only in male mice, offering new clues about how microplastics may affect cardiovascular health in humans.

The global food system is under growing scrutiny for its environmental and health impacts. It contributes substantially to climate change, biodiversity loss, and diet-related disease, making its current trajectory unsustainable.

The EU is considering introducing a blanket ban on the man-made chemicals called PFAS because of the risks they pose.

Researchers at Penn State find a rare, stress-sensitive neuron appears to help regulate blood flow in the brain of mice.

Warming temperatures and increased precipitation in the Canadian High Arctic are mobilizing new pathways for subsurface contaminants to spread from more than 2,500 contaminated sites associated with industrial and military sites across the region.

Climate change in Earth’s polar regions is emerging as an under-recognised driver of global health risks, with consequences reaching far beyond the Arctic and Antarctic, researchers argue.

For Michigan’s farmers, fall harvest is both the culmination of a year’s work and one of its most demanding stretches. Long hours, unpredictable weather and financial uncertainty can take a toll.

Researchers at North Carolina State University have shown a link between the size of cockroach home infestations and the levels of both allergens and endotoxins in those homes, with lowering roach infestation numbers through pest control triggering significant declines in the levels of allergens and endotoxins.

New study reveals how human astroviruses bind to humans cells and paves the way for new therapies and vaccines.
