Summary
Researchers discovered that amputated tissue from cold-water sea cucumbers (Psolus fabricii) remained alive and growing for over three years in ordinary seawater, challenging conventional assumptions about tissue survival outside the body. The findings, published in Science Advances, describe these creatures as "real-life zombies" and could have significant implications for biomedical sciences, particularly in tissue preservation and regeneration research.
