A UCLA research team has found that drugs being sold as fentanyl contain high amounts of the industrial chemical bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate, or BTMPS. This new substance of concern emerged in the illicit drug supply nearly simultaneously in multiple U.S. locations from coast-to-coast.

Our biceps and our brain cells may have more in common than previously thought.

Mitochondria are essential for generating energy that fuels cells and helps them function.

Years ago, a young patient’s mother told Emily McCourt, MD, associate professor of ophthalmology at the University of Colorado School of Medicine, that she hadn’t used a prescribed ointment to treat her baby’s chemical corneal burn but instead used her own breast milk.

Removing a blood clot from a large brain artery, then injecting the clot-dissolving drug tenecteplase into the artery resulted in stroke survivors being more likely to have better function 90 days after their stroke than those receiving standard clot removal, according to preliminary late-breaking science presented today at the American Stroke Association’s International Stroke Conference 2025. The conference, in Los Angeles, Feb. 5-7, 2025, is a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health.

Monitoring respiratory motion during diagnostic imaging and radiation therapy is crucial for accurate diagnosis and treatment. However, respiratory motion is rarely monitored during these procedures due to the lack of practical, non-invasive tools, leading to potential image quality issues.

Scientists are calling on the U.S. Centers for Disease Control and Prevention (CDC) to disclose data about the risks of bird flu to people and pets that was posted briefly online Wednesday and quickly deleted.

The UK government announced Friday an imminent ban in England on “bird gatherings” such as fairs, markets and shows, seeking to stop the spread of a highly contagious avian influenza.

The U.S. winter virus season is in full force, and by one measure is the most intense in 15 years.

Researchers at the University of Liège (Belgium) have uncovered a previously unknown mechanism that regulates the immune response against parasites. During a parasitic infection, specific immune cells, known as virtual memory T cells, become activated and express a surface molecule called CD22, which prevents an excessive immune reaction. This discovery could help in better-controlling inflammation and improving immune responses to infections.
