Five years later, naked mole-rat mortality rates still defy Gompertzian laws
Researchers discovered naked mole-rats defy aging laws, showing no mortality increase with age. Data doubling over five years supported this, contrasting with Damaraland mole-rats. Naked mole-rats resist age-related diseases, challenging demographic aging concepts.

Researchers have found that naked mole-rats, known for their eusocial behavior and long lifespan, do not experience an increase in mortality rates with age, contrary to Gompertzian laws. This conclusion was supported and strengthened after doubling the demographic data over five years. The study also provided insights into the social dynamics of these rodents and compared their lifespan data with Damaraland mole-rats, showing a gradual increase in mortality hazard with age in the latter. Naked mole-rats exhibit resistance to age-related diseases and maintain physiological characteristics throughout their lives, challenging the concept of demographic aging. The study's findings have implications for understanding exceptional lifespan evolution in mole-rats and the ecological factors influencing it. The research highlights the unique characteristics of naked mole-rats and the challenges in reproducing similar results due to the lack of comparable data collections worldwide.
