AI Facial Analysis Shows Promise for Assessing Biological Age and Patient Survival Risk

Researchers at Mass General Brigham are investigating how artificial intelligence can extract meaningful health signals from facial images. The work focuses on using AI facial recognition not for identification, but for medical assessment—specifically estimating a patient's biological age and survival risk based on subtle visual patterns. Biological

FDA Clears AI Tool for Breast Cancer Recurrence Risk Assessment via MRI

The U.S. Food and Drug Administration has granted clearance to a software tool designed to evaluate breast cancer recurrence risk through magnetic resonance imaging. The tool leverages artificial intelligence to analyze MRI data, offering clinicians an additional resource for treatment decision-making. Medical imaging AI continues to expand its

Scientists Identify Protective Mutation That May Shield Against Alzheimer's

Scientists Identify Protective Mutation That May Shield Against Alzheimer's Researchers have uncovered a rare genetic mutation that may explain why some individuals with a high hereditary risk of Alzheimer's disease maintain sharp cognitive function well into their 80s. The mutation appears to shield the brain from

Moderate Walking Shows Promise in Slowing Alzheimer's Progression, Study Finds

New research suggests that moderate physical activity, such as walking just 3,000 steps a day, could play a meaningful role in slowing Alzheimer's disease progression. Scientists found that physical activity was associated with reduced accumulation of tau proteins—harmful proteins linked to neurodegeneration—and approximately half the

Nobel Prize Awarded for Breakthrough in Light-Controlled Brain Cell Technology

A team of researchers has been honored with the 2026 Nobel Prize for their groundbreaking work in optogenetics, a technique that allows scientists to switch individual brain cells on and off using light. The breakthrough traces its origins to the study of tiny algae, which naturally respond to light. By

Fatty Liver Disease Is Actually Five Distinct Conditions, Researchers Find

Fatty liver disease, a condition affecting roughly 30% of adults worldwide, may be far more complex than previously understood. Researchers at the Mayo Clinic have discovered that what doctors have long considered a single disease is actually five distinct biological subtypes, each carrying different risk profiles for serious complications. The

University of Queensland Develops New Technology to Accelerate Alzheimer's and Parkinson's Drug Discovery

Researchers at the University of Queensland (UQ) have unveiled a new technology platform designed to streamline drug discovery for Alzheimer's and Parkinson's diseases. The approach reportedly offers a novel method for identifying and developing therapeutic candidates targeting these neurodegenerative conditions, which have proven exceptionally challenging for
