Colorectal cancer has long baffled scientists because, unlike most tumors, patients often do better when their cancers are packed with immune-suppressing regulatory T cells. New research finally explains why. Scientists discovered that these T cells ...

Scientists at Keck Medicine of USC are testing an experimental stem cell therapy that aims to restore the brain's ability to produce dopamine, the chemical whose loss drives Parkinson's disease. The early-stage clinical trial involves implanting lab ...

New research using rhesus monkeys suggests that the brain's relationship with alcohol may begin forming long before a person ever takes a drink. Scientists found that exposure to alcohol before birth reshaped the brain's dopamine system, a key player ...

Scientists in Australia have uncovered a clever new way to fight some of the most dangerous drug-resistant bacteria by targeting a sugar that exists only on bacterial cells. By designing antibodies that recognize this unique sugar, researchers were . ...

A new imaging breakthrough combines ultrasound and light-based techniques to generate vivid 3D images that show both tissue structure and blood vessel activity. Developed by researchers at Caltech and USC, the system delivers detailed results quickly ...

Researchers have figured out how psoriasis can quietly turn into joint disease for some patients. Immune cells formed in inflamed skin can travel through the blood and reach the joints, where they sometimes trigger inflammation. The key difference .. ...

People who switch to a fully unprocessed diet don't just eat differently--they eat smarter. Research from the University of Bristol shows that when people avoid ultra-processed foods, they naturally pile their plates with fruits and vegetables, ...

Kidney disease often creeps in silently, and many patients aren't diagnosed until major damage is already done. New research shows that even "normal" kidney test results can signal danger if they're unusually low for someone's age. By mapping kidney ...

Researchers have created the first complete map showing how hundreds of mutations in a key cancer gene affect tumor growth. By testing every possible mutation in a critical hotspot, they found that some changes barely boost cancer signals, while ...

Advanced care provided by air ambulance teams was linked to higher survival rates in major trauma patients. Researchers found that more people survived than predicted by standard models, including many with severe injuries and low chances of survival ...
