Even under general anesthesia, the human brain can analyze language, recognize different types of words, and predict what comes next in a story, according to a surprising discovery by Baylor researchers. The findings challenge our understanding of consciousness and suggest that the unconscious brain is far more capable than scientists previously realized.

Eating late at night could be putting your liver at risk, according to a large study led by Oregon Health & Science University. Researchers analyzed data from nearly 200,000 people and found that those who regularly ate after dinner or around bedtime had a 20% to 30% higher risk of liver disease, including fatty liver disease and cirrhosis.

Scientists have discovered that unusually small cancer cells carrying extra chromosomes can be far more aggressive than larger ones, growing faster, spreading more readily, and resisting common treatments. The surprising finding could help explain why some tumors are especially dangerous and provide a new way to predict cancer outcomes.

A rare examination of an Alzheimer’s patient’s brain revealed that regions cleared of amyloid plaques had remarkably little of the harmful tau buildup associated with memory loss, while neighboring areas showed extensive damage. The discovery suggests that removing amyloid may have lasting protective effects and could help slow Alzheimer’s progression, especially when treatment begins early.

Strokes are becoming alarmingly common among younger adults, with rates nearly doubling among people ages 20 to 54 over nearly three decades. Researchers found that blocked blood vessels in the brain accounted for much of the increase, while high blood pressure, diabetes, and substance use also became more common among younger stroke patients. Although survival rates have improved, more young adults may now face the lasting consequences of stroke.
