At the Indian Institute of Science, researchers have built a self-folding laboratory model that mimics the breast duct — the origin point of some of the body's most resistant cancers — asking a question that has long eluded medicine: why do cancer cells survive treatments designed to destroy them? By recreating not just the shape but the physical motion of living tissue, the team discovered that fluid flow transforms cancer cell behavior in ways a flat petri dish could never reveal. This work does not yet cure anything, but it moves science closer to understanding the hidden conditions that al
