Nearly a third of people in the U.S. have been exposed to unregulated contaminants in their drinking water that could impact their health, according to a new analysis by scientists at Silent Spring Institute. What’s more, Hispanic and Black residents are more likely than other groups to have unsafe levels of contaminants in their drinking water and are more likely to live near pollution sources.

Researchers have identified a novel genetic risk factor for SARS-CoV-2 infection, providing new insights into the virus’ ability to invade human cells.

A new study by researchers at Wayne State University links exposure to air pollution to an increased risk of type 2 diabetes.

More than three-quarters of older adults with dementia may be unaware of their diagnosis, a University of Michigan study finds. That number is even higher — up to 85% — among Mexican Americans. Researchers say physicians may not be diagnosing patients, or they may be witholding a diagnosis of dementia. 

Helen Schwerdt, assistant professor of bioengineering at the University of Pittsburgh, has received a $2.5 million NIH R01 grant to investigate dopamine's role in learning from rewards and punishments. Her team develops advanced neural interfaces to monitor dopamine and electrical activity in the brain, focusing on the striatum. This research aims to uncover how dopamine signals differ across brain regions during learning and could provide insights into neurological disorders like Parkinson's disease, where dopamine dysregulation plays a key role. The findings may pave the way for new biomarkers and treatments for cognitive and behavioral symptoms.
