Summer Science Books, Naked Mole Rats. July 3, 2020, Part 2

The pandemic has nixed many summer vacation plans, but our summer science book list will help you still escape. While staying socially distant, you can take a trip to the great outdoors to unlock the mysteries of bird behaviors. Or instead of trekking to a museum, you can learn about the little-known history of lightbulbs, clocks, and other inventions.

Our guests Stephanie Sendaula and Sarah Olson Michel talk with Ira about their favorite science book picks for summer reading.

Naked mole rats, native to East Africa, are strange mammals: They’re almost completely hairless. They live in underground colonies, like ants. And, like ants and bees, they have a single reproducing “queen.”

Their biology is also unique: They resist cancer, live a long time for such small rodents (often for 30 years or more), and have been found not just to tolerate high, normally toxic levels of carbon dioxide in their nests—but require them. And in the newest strange discovery, researchers writing in Cell earlier this year found that mole rats were prone to anxiety and even seizures when carbon dioxide levels get too low, such as in an environment similar to above-ground air.

Ira talks to the paper’s co-author Dan McCloskey, a neuroscientist at the City University of New York. McCloskey explains why mole rat brains might be helpful guides to human brains, especially in the case of infants who have seizures with high fevers. Plus, the mystery of how such homebodies found new colonies, and other naked mole rat oddities.
