500-year-old Greenland sharks' muscle metabolism linked to longevity, offering insights for human anti-aging and cardiovascular health.

Greenland sharks, the world's longest-living vertebrate, may hold secrets to human anti-aging and cardiovascular health. Researchers have found that muscle metabolic activity is a significant factor in the sharks' extraordinary longevity, with some specimens living up to 500 years. These findings could benefit both the conservation of the vulnerable species and human health.
