Scientists uncover how sperm defy a fundamental law of physics

Scientists have discovered that sperm and other microorganisms use a unique form of elasticity called 'odd elasticity' in their flagella, allowing them to swim efficiently in thick fluids by bending asymmetrically and bypassing traditional physics laws like Newton's third law. This discovery, supported by mathematical modeling and high-speed microscopy, could inspire new micro-robotic designs and improve understanding of microbial movement and human health issues related to cilia function.

Scientists Discover Sperm Challenging Newton's Laws

Scientists discovered that human sperm and algae can swim through viscous fluids by exhibiting 'odd elasticity,' allowing them to defy Newton's third law of motion, which typically states that every action has an equal and opposite reaction. This phenomenon results from non-reciprocal interactions in systems far from equilibrium, providing insights that could influence the design of self-assembling robots and understanding collective biological behaviors.
