Scientists Discover 'Immortal' Sea Cucumber Tissues, Redefining Life Concepts
Researchers at Memorial University in Newfoundland have discovered that certain tissues of the sea cucumber species Psolus fabricii exhibit 'immortal' characteristics. During routine research, the animal's severed tube feet remained alive and functional for weeks, prompting further study. The research team, led by PhD student Sara Jobson, found that these tissues could heal, regenerate, and absorb nutrients directly from their environment, despite being detached from the main organism. This discovery challenges traditional definitions of life, as the tissues maintain essential life processes without the ability to reproduce.
