The key to the fountain of youth?

I just read an interesting article on the physiology of long-lived species that was published in Physiology. Some animals seem to have discovered the secret to the fountain of youth. Take the long-lived naked mole rat (Heterocephalus glaber) for example. These animals are able to maintain juvenile traits across their lifespan by growing slowly, having low levels of hormones responsible for development and delaying the onset of sexual maturity. Dwarf […]

Secrets to Longevity

A new article published in Physiological Reviews compared some remarkable similarities and differences between naked mole rats and humans. Both are relatively long-lived, highly social and have low natural selection pressures. But, this is about all they have in common. While humans are prone to developing age-related cancer, diabetes, heart disease and dementias, naked mole rats are rather resistant to these diseases. Instead, naked mole rats appear to maintain a youthful […]
