A strategy inspired by the process responsible for muscle growth could lead to the development of stronger, longer-lasting materials. Hokkaido University researchers have developed a strategy to fabricate materials that become stronger in response to mechanical stress – mimicking skeletal muscle growth. Their findings, published in the journal Science, could pave the way for long-lasting materials that can adapt and strengthen based on surrounding conditions.

The strategy was inspired by the process that makes ...
