Scientists studying 1,300 golden retrievers have uncovered genetic clues explaining why some dogs are more anxious, energetic, or aggressive than others. Remarkably, several of the same genes linked to canine behavior are also tied to human traits .. ...

Mayo Clinic researchers have identified a rare mutation in the MET gene that can directly cause metabolic dysfunction-associated steatotic liver disease. The mutation disrupts the liver's ability to process fat, leading to inflammation, scarring, and ...

Researchers in Sweden have engineered a cell-free cartilage scaffold that can guide the body to rebuild damaged bone. By removing the cells but preserving the structure and natural growth signals, the material acts as a blueprint for the body's own . ...

A newly identified protein may hold the key to preventing diabetic blindness. Researchers discovered that LRG1 triggers the earliest damage in diabetic retinopathy by constricting tiny retinal blood vessels and reducing oxygen supply. In mice, ...

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, . ...
