A mysterious form of plague that spread across Eurasia thousands of years before the Black Death has finally revealed a crucial clue. Scientists analyzing ancient DNA discovered the bacterium Yersinia pestis in a 4,000-year-old domesticated sheep ...

Researchers have discovered a new way to increase a key brain protein damaged in Rett syndrome, a rare genetic disorder that affects thousands of children worldwide. Early studies in mice and patient-derived cells show the approach can restore normal ...

Most of our daily actions may happen without much thought. Researchers found that around 65% of everyday behaviors are triggered automatically by habit rather than conscious decisions. Many of these habits actually support our personal goals, helping ...

CBD and CBG, two non-intoxicating cannabis compounds, may help combat fatty liver disease by boosting liver energy reserves and restoring cellular cleanup systems. In the study, both compounds improved blood sugar control and reduced harmful lipids . ...

Cocaine addiction isn't simply a failure of willpower -- it's the result of lasting biological changes in the brain. Researchers at Michigan State University discovered that repeated cocaine use rewires communication between the brain's reward system ...

A Rutgers-led study found that eating less protein may help slow liver cancer in people with impaired liver function. When damaged livers can't properly clear toxic ammonia from protein metabolism, the excess ammonia can feed tumor growth. In mice, . ...

Advanced 3D reconstructions of the comb jelly's aboral organ reveal a sensory system far more complex than scientists expected. The organ contains a wide variety of specialized cells and is closely linked to the animal's nerve network, allowing it to ...

Researchers created an AI-driven liquid biopsy that scans patterns in fragments of DNA circulating in the blood. The system detected early liver fibrosis and cirrhosis--conditions that often go unnoticed until serious damage occurs. By analyzing ...

Scientists have uncovered new genetic rules that determine whether the immune system's "killer" T cells remain powerful long-term defenders or become worn out and ineffective. By building a detailed genetic atlas of CD8 T cell states, researchers ...

Growing neurons rely on chemical cues to find their targets, but new research shows that the brain's physical properties help shape those signals. Scientists discovered that tissue stiffness can trigger the production of guidance molecules through a ...
