Default More than Teeth - The Naked Mole Rat!

More than teeth : Nature : Nature Publishing Group

"In an unflattering light, a naked mole rat looks like a wrinkly sausage with oversized teeth, legs and a tail. And given that it spends all of its extraordinarily long life short of air in dark and overcrowded underground tunnels, where it frequently eats its own excrement, an unflattering light is probably the best that a naked mole rat can hope for. Still, the best science, like love and justice, is blind, so this week the naked mole rat (Heterocephalus glaber; also known as the sand puppy or desert mole rat) joins the illustrious list of animals judged to be of sufficient significance for an analysis of their genome sequence to be published."

"The creature is certainly an interesting curiosity, but in these cash-strapped times, why invest in the secrets of its genome?
The naked mole rat is one of Mother Nature's great survivors. The busy underground lairs in which the animals live almost always run low on oxygen and high on carbon dioxide. Steady subterranean temperatures have sapped the creatures' ability to regulate their body temperature. Yet what they sacrifice in quality of life they more than make up for in extraordinary quantity. Comfortably the longest-living rodent, naked mole rats can live for more than 30 years. They seem impervious to cancer and do not feel some types of pain."

"The information published on its genome and transcriptome has already revealed patterns of gene expression different from those in humans, mice and rats, and this may underlie its longevity. With further study, mechanisms of ageing, genetic regulation of lifespan, adaption to extreme environments, low-oxygen tolerance, cancer resistance, sexual development and hormonal regulation are up for grabs."

Those are in the baby opossum league.... they're so darn ugly they're cute. I bet everyone whose got hairless cats and hairless chihuahuas would like the looks of naked mole rats. See how cute chihuahuas can be, http://upload.wikimedia.org/wikipedi..._Chihuahua.jpg .
