Scientists discover self-healing ability in cracked metal

New mechanism for self-healing nanocracks discovered in metals Researchers identified a novel mechanism that allows nanocracks in metals to heal without external pressure. Through molecular dynamics simulations, they found that migrating grain boundaries generate crystal defects, or disclinations, which close…

Fungal mycelia as control mechanisms in biohybrid robots

Researchers have created biohybrid robots using fungal mycelia, which are robust and responsive to environmental cues. These living components generate electrical signals to control robot movements, such as in a soft, starfish-inspired robot and a wheeled robot. By stimulating mycelia…
