World's Finest For Science: Physicists, Biologists Team Up To Determine How Cancer Spreads

Cancer cells that can break out of a tumor and invade other organs are more aggressive and nimble than nonmalignant cells. Such cells exert greater force on their environment and can more easily maneuver small spaces, researchers write, due to a systematic comparison of metastatic breast-cancer cells to healthy breast cells which revealed dramatic differences between the two cell lines in their mechanics, migration, oxygen response, protein production and ability to stick to surfaces. read more
