Who would've thought a wrinkled-up, nearly blind sac of a mammal would be such a guru on ways to stay forever young? That pink and flabby-skinned rodent we fondly call the naked mole-rat (Heterocephalus glaber) once again is teaching us something about...
"But to me, the most amazing thing is that they never stop having babies – they don't have a drop in fertility as they age. We want to understand how they do this."
What's more, that number of egg cells seemed to increase day by day from when she was born,"raising the possibility," researchers If the only breeding female in a group dies or is removed from the colony, other females need to be ready to step up and fight to the death to take her place. This is probably why even subordinate females in a colony, who are not actively breeding, appear to maintain abundant germ cells in their ovaries. Even at 10 years of age that still appears true.
But there's reason to suspect that a high fertility rate is maintained for decades among naked mole-rats.found that naked mole-rats do not face an increased risk of death as they age. They seem to grow older in a way that differs from just about every other mammal we know of.
