Summary

Story summary

Marine scientist Sara Jobson reported that severed tube feet from sea cucumber Psolus fabricii survived three years in a seawater tank.
The fragments showed no degradation, stayed attached to glass, and grew for months.
Researchers documented immune activity, cell division, diversification, tissue reorganization, and amino-acid absorption from seawater.
Marine biologist Noé Wambreuse called the finding tissue immortality, prompting scientists to analyze telomere length.
