🔬Severed sea cucumber tissue survived 3+ years in seawater — with zero lab support

A team at Memorial University of Newfoundland found that detached tissue from the sea cucumber Psolus fabricii kept living and growing for over three years in ordinary natural seawater — no sterile conditions or supplements required. The tissue healed, showed immune activity, and reorganized itself; researchers only stopped to publish. Reported in Science Advances, the effect appears unique to this species — no tested sea star, urchin, or brittle star came close. Could this strange creature hold clues to why cells age at all?
