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.

"Unraveling the Mysterious Connection: Zebra Stripes and Sperm Tails"

Mathematicians have discovered a strange link between zebra stripes and sperm tails. Taking inspiration from how stripes and spots form in various organisms, researchers analyzed the patterns created by the flagellum of sperm. Using reaction-diffusion dynamics, they found that the beating motion of the flagellum generates oscillations that can be modeled with striped patterns. The researchers compared their simulations to experimental data from sperm and green algae, finding that their simplified model captured flagella movement. This study could have implications for understanding sperm motility and male fertility.
