UCLA scientists have characterized the structure and function of a key survival protein in breast cancer cells that helps explain how these tumors resist environmental stress and thrive in acidic, low-oxygen environments that would normally be toxic to healthy cells.

Microplastics could be fueling neurodegenerative diseases like Alzheimer's and Parkinson's, with a new study highlighting five ways microplastics can trigger inflammation and damage in the brain.

A new study suggests that certain genetic differences, passed down from ancient human ancestors, and exposure to common present-day chemicals could explain why some women are more likely to develop endometriosis.

Triple-negative breast cancer (TNBC) is one of the most aggressive and treatment-resistant forms of breast cancer. It grows quickly, spreads early and lacks the hormone receptors that make other breast cancers treatable with targeted therapies.

In a study funded by the National Heart, Lung, and Blood Institute, new research from Johns Hopkins Medicine adds to existing evidence that smoking fewer cigarettes does not eliminate cardiovascular disease risk, and quitting entirely is the most effective strategy for improving health.

A study carried out by the University of Bonn and the University Hospital Bonn throws light on how an important receptor can be inhibited.

First and foremost, we breathe in order to absorb oxygen - but this vital rhythm could also have other functions. Over the past few years, a range of studies have shown that respiration influences neural processes, including the processing of stimuli and memory processes.

Real progress in oral health doesn't come from expensive gadgets, but from better daily habits. That is the conclusion of dentist- periodontist Tim Thomassen in his dissertation Oral Disease Prevention, which he will defend on 12 December at the University of Amsterdam.

The study shows restless legs syndrome is associated with higher Parkinson's disease incidence, raising questions about treatment impacts on symptoms.

A new USC study shows teens with higher blood levels of per- and polyfluoroalkyl substances (PFAS) measured before bariatric surgery had smaller improvements in blood sugar over five years, including fasting glucose and hemoglobin A1c (HbA1c), which measures average blood sugar levels over the past 60-90 days.
