AI scans 400,000 Reddit posts to flag overlooked GLP-1 side effects
Penn researchers used AI to analyze more than 400,000 Reddit posts, surfacing patient-reported side effects of GLP-1 drugs like semaglutide and tirzepatide that traditional clinical trials may have missed. The study highlights a growing role for social media mining in pharmacovigilance, where real-world patient experiences can outpace formal reporting systems. The findings could push regulators and drugmakers to take a closer look at symptoms users have long been discussing online.

More ambulances are carrying blood for transfusions. Experts say it will save lives
Paramedics across the country are increasingly stocking ambulances with blood products, allowing trauma patients to receive life-saving transfusions before they ever reach a hospital. The shift addresses a critical window in trauma care, where uncontrolled bleeding remains one of the leading causes of preventable death. Experts say getting blood into patients faster could dramatically improve survival rates in severe injury cases.

Somatostatin in brain regulates immune cells to mitigate dementia, opening path for treatment with existing drugs
Researchers at DGIST have identified how somatostatin, a neurotransmitter naturally present in the brain, directly controls immune cells to reduce the progression of Alzheimer's disease. The discovery centers on the ability to switch these immune cells from a disease-worsening state into a protective one. Because somatostatin-based drugs already exist, the findings open a realistic near-term pathway for repurposing approved medications as dementia treatments.

A 'wake-up call' from leading sleep scientists: Nighttime warming threatens the sleep of billions
Nights are warming faster than days across most of the populated world, and leading sleep scientists say the consequences are already being felt at a global scale. A new article co-authored by the presidents of the World Sleep Society and International Pediatric Sleep Association warns that rising ambient temperatures are degrading sleep quality and duration for billions of people. Without significant adaptation measures, the researchers say the problem will worsen considerably as climate change accelerates.

Watch: As AI Makes More Health Coverage Decisions, the Risks to Patients Grow
Health insurers and Medicare are increasingly deploying artificial intelligence to determine what treatments patients receive — a shift that critics say prioritizes cost-cutting over care. Class action lawsuits allege that some insurers have used AI systems to wrongfully deny coverage, and emerging research suggests the technology carries significant risks for patient outcomes. The trend is drawing scrutiny from regulators and advocates who warn that algorithmic decision-making lacks the nuance required for complex medical cases.
