Scientists at Kyoto University have discovered that human sperm defy Newton’s third law by propelling themselves through viscous fluids using their tails. The study reveals that sperm tails exhibit ‘odd elasticity’, enabling forward motion with minimal energy loss despite resistances, a phenomenon also modeled in green algae movements.
