The Science and Efficacy of Ancient Needles

Can an ancient healing practice really work—and if so, how much of its effect comes from the body and how much comes from the mind? Acupuncture has traveled a remarkable path from traditional Chinese medicine to a widely accepted modern therapy, attracting everyone from chronic-pain patients to elite athletes. In this episode, we explore the science behind acupuncture, examining its traditional explanation of energy flow alongside modern research into nerves, connective tissue, and pain perception. We investigate why evidence for chronic pain relief is considerably stronger than for many of the other conditions acupuncture is promoted to treat, and why scientists continue to debate the role of physiological effects versus placebo responses. The story reveals a fascinating middle ground between ancient tradition and modern medicine—where a treatment can offer meaningful relief while the precise mechanisms behind its effectiveness remain surprisingly difficult to pin down.https://www.economist.com/science-and-technology/2026/05/01/does-acupuncture-work
