Naked moles seem to ignore the mathematical equation that describes aging, the Gompertz Rule.

In the world of animal models, naked moles are "supermodels".
they have very few cancers, are resistant to some types of pain, and can survive for up to 18 minutes without oxygen.
, however, a new study shows that their greatest featist is not to age.
the first study of the life history of thousands of naked mole rats, they did not increase their risk of death with age.
While some scientists caution against jumping into any conclusions, many believe the latest data are important and compelling.
naked moles are cave rodents with wrinkled pink skin and large fangs.
scientists have long noted that naked moles show few signs of aging and live far longer than rodents of this size.
captive mice can live up to four years.
and based on the size of naked mole rats, they are less likely to survive for six years.
but the truth is that some naked mole rats have lived for more than 30 years, and at this age, some females are still able to reproduce.
comparative biologist Rochelle Buffenstein has been studying naked moles for more than 30 years and has gradually collected valuable data on the animal's entire life cycle.
for every naked mole she cared for, she recorded the time of birth and death, and whether it was killed or given to other researchers.
, who works at Calico, a biotech company owned by Google in San Francisco, says her findings are shocking: Naked moles seem to ignore the gombetz law, the mathematical equation that describes aging.
1825, the British mathematician Benjamin Gompertz discovered that the risk of death increased exponentially as they grew older.
for example, for humans, the risk of death roughly doubles every eight years after age 30. Joao Pedro De Magalhaes, a geroniatrician at the University of Liverpool at
, says the law applies to all adult mammals.
but Buffenstein didn't find this trend in her lab animals.
when sexual maturity is reached at 6 months old, each naked mole is slightly more likely to die each day than one in 10,000.
the odds remain the same for the rest of their lives.
Buffenstein reported the findings in the journal Life.
