Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, SARS ...

Scientists have identified genetic variants that may make some people less responsive to GLP-1 drugs used to treat Type 2 diabetes. Roughly 10% of the population carries these variants, which appear to cause a mysterious form of "GLP-1 resistance." . ...

A major review of nearly 8,000 participants found that collagen supplements can improve skin health and ease osteoarthritis symptoms, especially when taken consistently over longer periods. Researchers also found modest benefits for muscle and tendon ...

A large study of older adults in Brazil found that adding extra salt at the table is still a common habit, especially among men. While too much salt is linked to serious health problems and faster cognitive decline, researchers discovered that women ...

For decades, pancreatic cancer has been one of the most lethal cancers, with few effective treatment options. A new drug, daraxonrasib, targets the KRAS mutation that fuels most pancreatic tumors--something many scientists once thought couldn't be .. ...

A newly discovered genetic clock acts as the master timekeeper for development, orchestrating crucial bursts of gene activity throughout a worm's growth. When the clock is disrupted, development stops, offering fresh clues about how growth-related .. ...

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 ...
