Summary

Story summary

Researchers at Kyoto University found that human sperm swim efficiently using odd elasticity, enabling movement without equal resistance.
This discovery challenges classical mechanics by demonstrating that energy is not recovered in subsequent strokes.
The study's findings could impact soft robotics and enhance understanding of cellular movement in diverse environments.
