A chemical commonly used in dry cleaning and found in some household products may be an overlooked threat to liver health. Researchers found that people with detectable levels of tetrachloroethylene (PCE) in their blood were three times more likely . ...

Could math help explain why some relationships survive life's inevitable stresses while others slowly fall apart? Researchers have spent decades developing mathematical models that treat romantic feelings as changing systems, revealing patterns in .. ...

A rediscovered memoir reveals that celebrated War of 1812 veteran Shadrack Byfield was far more rebellious and troubled than history has portrayed, battling chronic pain, poverty, authorities, and even rivals at his local chapel. The soldier who ...
