The naked mole-rat Heterocephalus glaber , also known as the sand puppy ,  is a burrowing rodent native to parts of East Africa. It is closely related to the blesmols and is the only species in the genus Heterocephalus of the family Heterocephalidae. It has a highly unusual set of physical traits that allow it to thrive in a harsh underground environment and is the only mammalian thermoconformer , almost entirely ectothermic cold-blooded in how it regulates body temperature. The naked mole-rat lacks pain sensitivity in its skin, and has very low metabolic and respiratory rates.
Naked mole rats defy the biological law of aging
The naked mole rat--a new record for the oldest living rodent. - Abstract - Europe PMC
A new wheat species, Triticum parvicoccum , hitherto found only in archaeological excavations, is described. Rachis fragments and grains have been found in sites in the Near East and the Balkans. An attempt to reconstruct the morphology of the plants has been made, and the phylogenetic relationships with the main wheat species are discussed. Behre K. Hachmann R. Briggle L.
Weird: Naked Mole Rats Don't Die of Old Age
In the world of animal models, naked mole rats are the supermodels. They rarely get cancer , are resistant to some types of pain, and can survive up to 18 minutes without oxygen. But perhaps their greatest feat, a new paper suggests, is that they don't age. 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.
