Scientists have uncovered a surprising new way the immune system fights cancer, overturning a core belief that has guided immunology for decades. The research found that when cancer cells shut down a key immune-recognition molecule called MHC I--a .. ...

A massive study of more than 600,000 U.S. veterans suggests that popular GLP-1 drugs such as semaglutide may do far more than help with diabetes and weight loss--they could also fight addiction itself. Researchers found that people taking these ...

Scientists have developed an experimental diabetes and obesity pill that works in a completely different way from drugs like Ozempic. Rather than reducing hunger, it activates metabolism in skeletal muscle, helping lower blood sugar and increase fat ...

A newly identified group of amygdala neurons appears to play a central role in anxiety and social behavior. Restoring normal activity in this tiny brain circuit reversed anxiety and social deficits in mice, revealing a promising new target for future ...

French fries may be the real potato problem. A large study tracking more than 205,000 people for nearly 40 years found that eating three servings of fries per week was linked to a 20% higher risk of developing type 2 diabetes, while baked, boiled, or ...

Scientists have uncovered evidence that autism may include at least two biologically distinct subtypes, each marked by a different pattern of brain communication. By combining brain scans from nearly 1,000 people with autism with insights from 20 ...

A newly identified protein may be one of the biggest obstacles holding CAR T-cell therapy back. Researchers found that NFIL3 causes these engineered immune cells to become exhausted and lose their cancer-fighting power over time. When NFIL3 was ...

A major study suggests that some of the groundwork for brain development may be shaped before birth through a surprising partnership between a baby's genes and gut microbes. Researchers found that epigenetic changes present at birth can influence how ...

Researchers found that social behavior begins in the brain before it becomes visible as movement. In zebrafish, a coordinated pattern of activity spread across the brain several seconds before the animals approached another fish. A higher brain ...

A surprising new study suggests that when it comes to pancreatic cancer, the kind of fat you eat may matter more than how much. Researchers found that oleic acid--the main fat in olive oil and several other common foods--sped up tumor growth in mice ...
