"The design mimics the structure of leaf veins," said Li Xiaofei, a member of the team, "which balances the strength and speed of the actuator." The result was published in Advanced Materials.

Kuhn could have illustrated his point with almost anything: for example, the science of plant leaves and their structure. The networks of veins in leaves share universal features that demand ...

Darkened, thickened bands between leaf veins—seen here on an American beech leaf—are characteristic symptoms of beech leaf disease (BLD). First detected in northeastern Ohio in 2012, BLD has since ...
