The fact that the risk of dying randomly is so much lower means that, from an evolutionary standpoint, it makes more sense to invest in cellular mechanisms that might allow the creatures to live longer.

But Finch cautions against overinterpreting the data. Mature chubby tube. Science 23 November VolIssue By David Malakoff Nov. Naked mole rat with glasses. Photo of the Day. By Meredith Wadman Nov.

In June, Gorbunova and Seluanov announced the discovery that the rodents also produce a novel cellular compound that appears to prevent them from getting cancer.

But Buffenstein says the data simply do not show the typical aging pattern seen in mammals or any other animals. Image via Bob Owen. How to contact the news team. Climate change poses major threat to U. Erotic nursing bra. Photos Submit to Our Contest. That hairless, wrinkly, fanged rodent in the photo above?

Even Rochelle Buffenstein does not have the data on this. But Buffenstein did not see this trend in her lab animals. Mice in captivity live at most 4 years; based on their size, naked mole rats would not be expected to live past 6 years.

It turned out that, compared to mouse ribosomes, these three-part structures made between four and forty times fewer errors during the translation process. Gorbunova and Seluanov want to proceed by seeing whether either of their special mechanisms—longevity or cancer resistance—could be introduced into mouse cells, and whether they might lead to corresponding extensions in lifespan.

What she found was astonishing, says Buffenstein, who works at the longevity-focused Google biotech spinoff Calico in San Francisco, California: Wombats make cube-shaped poop, thanks to unique intestines Nov. The first study to analyze the life histories of thousands of naked mole rats has found that their risk of death doesn't go up as they grow older, as it does for every other known mammalian species.

Although some scientists caution against any sweeping conclusions, many say the new data are important and striking. For each animal in her care, she recorded the date of birth and when it died, and whether it was killed for an experiment or given away to other researchers. They rarely get cancerare resistant to some types of pain, and can survive up to 18 minutes without oxygen. InBritish mathematician Benjamin Gompertz found that the risk of dying rises exponentially with age; in humans, for instance, it doubles roughly every 8 years after the age of But the naked mole rats did.

Science Age of Humans. Naked mole rat with glasses. What she found was astonishing, says Buffenstein, who works at the longevity-focused Google biotech spinoff Calico in San Francisco, California: Tiny microscopic structures called ribosomes handle this translation, reading genetic instructions that specify a particular recipe and churning out the protein accordingly.

The ribosomes in almost every multicellular organism on the planet is made up of two large pieces of RNAa genetic substance similar to DNA. Scientists have long noted that naked mole rats—burrowing rodents with wrinkled, pink skin and large protruding teeth that live in large, subterranean colonies—show few signs of aging and far surpass the life span expected of a rodent this size. Taiwanese scientists fight construction of a new port they say would damage a unique reef By Andrew Silver Nov.

Even Rochelle Buffenstein does not have the data on this.

Why are naked mole rats blessed with these anomalous, life-extending characteristics?

Adult naked mole rats have a daily chance of dying of about one in 10, More—and older—mole rats are needed to be sure that the risk of dying really is flat, Finch argues. In the world of animal models, naked mole rats are the supermodels. Indeed, the big mystery now is what happens in naked mole rats after 20 or 30 years, says Matthias Platzer, a biologist at the Leibniz Institute on Aging in Jena, Germany.
