From screen star to Parkinson's crusade: Michael J. Fox's mission to cure
Michael J. Fox says his Parkinson's diagnosis at age 29 reshaped his life, steering him from acting toward funding research and advocating for patients. His foundation has funded about $3 billion in Parkinson's research since 2000 and helped advance breakthroughs like a crucial spinal fluid test. Fox and foundation CEO Deborah W. Brooks accepted the Philanthropic Organization of the Year award at The Hollywood Reporter/Social Impact Fund summit, underscoring a shift from stardom to a lifelong mission to cure the disease and give patients a voice.

Decade-long marathon study finds heart remains resilient in recreational runners
A 10-year study of 152 recreational male marathon runners found that marathon-induced troponin T release after races was not linked to long-term changes in right ventricular function; left-ventricle changes occurred but stayed within normal limits, suggesting endurance training does not cause lasting right-heart damage in most recreational athletes, though the sample is small and one should consult a doctor if concerned.
Vitamin A's Role in Tumor Immune Evasion and New Cancer Treatment Avenues
Scientists have discovered that a vitamin A metabolite, retinoic acid, can suppress the immune system's ability to fight cancer by promoting immune tolerance. They developed inhibitors that block this pathway, restoring immune responses and improving cancer vaccine efficacy, paving the way for new immunotherapy treatments.
Silicon Valley's Pursuit of Happiness Metrics
The JoyScore Experiment at a rave aims to quantify happiness and social connection through biometric signals like brain activity, blood biomarkers, and self-reports, exploring whether dance and music can be scientifically measured to promote longevity and well-being.
Genetic and Microbiome Insights into Achieving a Century of Life
A genetic study of 117-year-old supercentenarian Maria Branyas reveals rare biological traits linked to healthy aging, challenging traditional aging markers like telomere length and offering potential insights for extending healthspan and lifespan.
2025's Top Medical Breakthroughs Transforming Healthcare
2025 has seen major medical breakthroughs including remote robotic surgery, a blood test for Alzheimer's, brain implants for ALS, advances in organ transplants, and gene editing treatments, transforming healthcare and patient outcomes.
Aging Immune Cells Alter DNA to Maintain Inflammation
Research shows that aging immune cells, specifically macrophages, can sustain a heightened inflammatory state through a pathway involving GDF3 protein, which may worsen responses to severe infections like sepsis; targeting this pathway could lead to new treatments for age-related inflammatory conditions.
Scientists Confirm Creatine's Benefits for Brain, Heart, and Muscle Health
Recent scientific research confirms that creatine, a common supplement traditionally associated with athletic performance, also significantly benefits brain and heart health by supporting cellular energy and neurotransmitter function, with studies showing it is safe for general use and potentially crucial for addressing creatine deficiency disorders.
Watching Brain Surgery for Alzheimer's Cure Research
The article explores cutting-edge Alzheimer's research, including brain surgery to collect tissue, laboratory studies on toxic proteins, and promising drug developments, suggesting that curing Alzheimer's may be achievable in the future.
Plant-Based Serum Promotes Rapid Hair Regrowth, Scientists Find
Scientists developed a plant-based hair serum containing Centella asiatica extract, which showed a 25% increase in hair thickness in a short, 8-week trial, suggesting potential for hair regrowth, though further research is needed to confirm efficacy and safety.
Secret Brain Hack to Simplify Exercise
Research suggests that applying vibration to tendons can alter sensory signals sent to the brain, making exercise feel easier and allowing individuals to exert more effort without perceiving increased difficulty, potentially encouraging more physical activity.
