Unveiling the Unexpected Capabilities of the Cytoskeleton: Nature's High-Tech Marvel

Researchers at the University of Göttingen and ETH Zurich have discovered surprising properties of the cytoskeleton, specifically the two types of intermediate filaments found in mobile and stationary cells. Using optical tweezers, they found that vimentin filaments become softer and retain their length when stretched, while keratin filaments become longer and retain their stiffness. The results provide insights into the mechanical properties of different cell types and could inspire the design of new sustainable materials with tailored properties.
