Naked mole rats look like walking steamed spring rolls (with tails). But, beneath their translucent skin, they have a 35 million year old superpower: they are super carbon dioxide breathers (trust us, they’re joining the Avengers). And it’s not like they simply tolerate CO2—the way you might suffer through the exhaust pouring from a tailpipe. They need it. And, they need a lot of it. Imagine an eight-by-eight elevator packed with 1,100 people—that’s the level of CO2 a nest full of mole rats need in order to survive. The question is: HOW? Because naked mole rats are mammals just like us. It should be toxic to them, but... it isn’t. It’s actually had a ton of benefits for them: CO2 has shaped their eusocial, insect-like society and might explain their long lives and resistance to cancer. The answer to all of this lies in a genetic mutation. It's a genetic mutation only two mammals have: mole rats and humans. And, unlocking that code in these little hairless wonders could one day solve certain forms of autism, epilepsy, and schizophrenia in us. Dr. Dan McCloskey and his colony of 300 naked mole rats at CUNY College of Staten Island are trying to figure out this naked mole rat sized mystery.
