Hydras: Our Immortal, Tentacled Friends

The video explores the concept of senescence, the process of aging and decline in multicellular organisms, and highlights exceptions like hydras and certain jellyfish. Hydras, small freshwater polyps, are nearly immortal due to their ability to regenerate using new stem cells. A study from the Max Planck Institute confirmed that hydras do not show signs of aging, maintaining fertility and low mortality rates. This unique trait is attributed to their simple body structure and constant stem cell production. The findings suggest potential breakthroughs in aging and disease research, particularly for conditions like Alzheimer's.
