The powerful role of exercise in maintaining skeletal muscle could be the key to improving health and resilience in older age, according to new research from Monash University. The new research, published on the bioRxiv preprint server, used preclinical models to uncover the key role a protein found in skeletal muscle, NOX4, plays in this process. https://medicalxpress.com/news/2026-06-secret-healthy-aging-skeletal-muscle.html Wed, 10 Jun 2026 21:20:03 EDT news700326134 Researchers at Baylor College of Medicine have uncovered a fundamental principle underlying how the human brain processes meaning across multiple languages. In a new study posted to the bioRxiv preprint server, scientists recorded the activity of individual neurons in the human hippocampus and found that bilingual people appear to organize concepts in a shared neural structure—even when speaking entirely different languages. https://medicalxpress.com/news/2026-06-bilingual-brains-concepts-aligned-languages.html Wed, 10 Jun 2026 15:20:01 EDT news700321058 Combining clinical expertise and experience with the vast and ever-increasing knowledge of artificial intelligence has the potential to transform health care by providing earlier diagnoses and predicting outcomes.

He says that every second, hospitals generate "enormous streams of ECG data—electrical traces of the heart that accumulate into one of medicine's richest, most underused archives." For decades, most of this information had been treated as crucial in the moment, but it goes unused later. https://medicalxpress.com/news/2026-04-ai-cardiac-minutes-early.html Wed, 29 Apr 2026 18:40:06 EDT news696679606 Researchers from the University at Buffalo and Roswell Park Comprehensive Cancer Center are developing an artificial intelligence tool to help surgeons better identify lung cancer patients at risk for postoperative complications.

Dyslexia, the world's most common learning disorder impacting reading, spelling and writing, is estimated to affect up to 20% of the global population. Until now, traditional approaches to studying dyslexia, such as behavioral and neuroimaging methods, have provided valuable insights but remain limited in their ability to test the underlying mechanisms of reading impairments. https://medicalxpress.com/news/2026-04-ai-brain-successfully-mimics-dyslexia.html Wed, 22 Apr 2026 11:20:05 EDT news696071770 Carnegie Mellon researchers have proven that widely available earbuds can double as heart-monitoring devices, capturing subtle cardiac activity with near-clinical accuracy and potentially expanding access to long-term, at-home care. By repurposing built-in components, the team transformed these commonplace devices into heart-vibration sensors that measure heart valve activity with nearly the same accuracy as chest-mounted medical devices. https://medicalxpress.com/news/2026-04-earbuds-heart-health.html Wed, 08 Apr 2026 16:40:04 EDT news694877869 Because the immune systems of people with inborn errors of immunity (IEI) don't function like everyone else's, it was unclear until now how well COVID-19 vaccinations protected them. In a new study, posted on the medRxiv preprint server, scientists have identified that even IEI patients who usually fail to produce the usual neutralizing antibodies used to measure vaccine success benefited from three COVID-19 vaccine doses. https://medicalxpress.com/news/2026-04-dose-covid-vaccine-crucial-immunocompromised.html Thu, 02 Apr 2026 15:10:02 EDT news694347628 Each year, 1 in 5 Canadians will experience a mental health issue, and about 50% will have experienced a mental Illness by age 40.
