Tries hard. Doesn't quite make it out of the oven in one piece.
Summary
A study from Tonji University in Shanghai reveals that naked mole rats' exceptional longevity—living up to 40 years compared to 3 years for mice—may be linked to their superior DNA repair mechanisms. These rodents are resistant to cancer, brain deterioration, and arthritis, making them valuable subjects for understanding aging processes. The research focuses on how their cells efficiently repair damaged DNA strands, potentially uncovering biological secrets to extended lifespan.
