Alzheimer's disease (AD), a progressive neurodegenerative disorder, is one of the leading causes of dementia worldwide, and currently has no definitive cure. 

A new 20-year study of nearly 11,000 adults in Bangladesh found that lowering arsenic levels in drinking water was associated with up to a 50 percent lower risk of death from heart disease, cancer and other chronic illnesses, compared with continued exposure.

Researchers tracked 85 young adults over a four-year period, finding that increases in ultra-processed food consumption were linked with elevated blood sugar and early signs of diabetes risk.

Weather patterns that produced five severe heat waves in Europe over the past 30 years could kill thousands more people if repeated in today’s hotter global climate, a new study finds.

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.
