• Next-Gen Cancer Drug Shows Anti-Aging Potential A drug originally designed for cancer treatment was found to extend lifespan in yeast by influencing a major growth-control pathway. This opens the door to anti-aging therapies beyond oncology.

• Medicaid Expansion & Lung Cancer Survival A new study linked Medicaid expansion to improved lung cancer survival rates, highlighting the impact of healthcare access on patient outcomes.

🏛️ Healthcare Policy & Technology

• HHS Releases AI Strategy The U.S. Department of Health and Human Services unveiled its AI strategy to improve efficiency, innovation, and patient outcomes. Expect more integration of AI into diagnostics, patient monitoring, and administrative workflows.
