The invention is a metamaterial, which is a material engineered to feature new and unusual properties that depend on the material’s physical structure rather than its chemical composition. In this case, the researchers built their metamaterial using a combination of simple plastics and custom-made magnetic composites. Using a magnetic field, the researchers changed the metamaterial’s structure, causing it to expand, move and deform in different directions, all remotely without touching the metamaterial.

For many cancer patients, side effects from radiation can be debilitating. But a new way of delivering radiation treatment has proven effective at eliminating a hard-to-treat cancer with the only side effect being light skin discoloration, even nine months after treatment. This new treatment, step-and-shoot proton arc therapy, is the first to be used by physicians and scientists to treat a patient at Corewell Health William Beaumont University Hospital in Royal Oak, Michigan.
