image: Following injury, planarians undergo a stem cell response (labeled in green) that leads to new tissue growth and the regeneration of missing structures (such as the head). Weak static magnetic fields can change stem cell responses to injury, as seen following exposure to a 200 μT field, which blocks stem cell activity and therefore regeneration. This material relates to a paper that appeared in the Jan. 30th, 2019, issue of Science Advances, published by AAAS. The paper, by A.V. Van Huizen at Western Michigan University in Kalamazoo, MI, and colleagues was titled, "Weak magnetic fields alter stem cell-mediated growth." view more
