Tiny micro- and nanoplastic fragments seem to be turning up everywhere, including one of the most well-protected parts of the human body—the brain. In a recent study conducted by Chinese researchers, they found microplastics ...

When the liver fails, toxins—such as ammonia—that should be filtered from the blood build up and reach the brain. The result is hepatic encephalopathy (HE), a devastating neurological complication of liver disease that can ...

Patterns of molecular activity in the blood may hold clues not only to how fit someone is, but also to the biological processes that support physical performance. Researchers at MIT, GE HealthCare, and the U.S. Military Academy ...

Alzheimer's disease (AD) is a neurodegenerative disorder that leads to progressive memory loss and a decline in mental functions. Several past studies have linked this disease to the accumulation of the protein amyloid-β ...

Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to lose function and die over the following days—has remained one of the most important unanswered ...

Millions of people worldwide carry viral infections they acquired at birth, often for life. For a long time it was assumed that the immune system hardly fights these pathogens. Researchers from the University of Basel show ...

The quail is a small, unassuming bird that glides rather than flies and prefers to hide under bushes than to perch on top of a tree. And now, it's also helping scientists understand serious birth defects in humans.

Published in BMC Medicine, the study analyzed data from over 150,000 participants and found the strongest associations in people who experienced adversity in both childhood and adulthood. These individuals were more frail ...

Scientists have uncovered an unexpected way cells can generate cancer-driving proteins—by cutting RNA into shorter, functional fragments rather than following the standard blueprint. This process, newly termed as "RNA dicing," ...

An AI model (REDMOD) can pick up the very early subtle tissue changes of pancreatic ductal adenocarcinoma, the most common form of pancreatic cancer, which conventional imaging and the human eye find difficult to detect, ...

For most of us, the sense of smell is an integral part of everyday life; it plays a critical role in providing information about our surroundings, alerting us to potential dangers, enhancing our sense of taste, and evoking ...
