A lab force on bone extended lifespan in older mice through a signal called PEDF

What the research found
News coverage of this experiment circulated on 30 October 2026, including a Science magazine news item. The paper itself is Cell Metabolism, online 23 October 2026, DOI 10.1016/j.cmet.2026.09.020. Zhimin Zhang and Xiaochun Bai at Southern Medical University, with Lu Di (Kunming Medical University) and Lu Sheng (Kunming University of Science and Technology), studied how bone senses force. The paper text says deleting the force sensor Piezo1 in osteocytes shortened median survival by 13.2 percent in male mice and 10.7 percent in female mice. A laboratory loading device, applied in mice aged 20 to 24 months for four months, extended healthspan and lifespan by 9.4 percent, or 79.5 days, in the abstract. A Southern Medical University account of the same work, dated 27 October 2026, reported average lifespan gains of 11.9 percent in females and 7.7 percent in males. Those percentages are the university figures, and they cover both sexes. PEDF is described as a force-responsive signal from bone that, in people, is associated with healthy aging. That human link is an association, not a treatment. The device is a lab tool. It is not a result about human lifespan. Not medical advice.
Evidence level: Animal study. Results in animals or cells often don't carry over to people.
