    Did you know that ground sloths the size of elephants were a thing? Here’s some mummified skin with fur belonging to a ~10,000 year old ground sloth called Mylodon darwinii, found inside a cave in Chile.

    Barn owls have to be among the superb-est of s. Amazing cochlea (thx ), giving them hearing abilities like no other bird. Asymmetrical external ears—but not bony, middle, or inner ears—gives them superb abilities to localize sounds in space.

    Only Republicans voted to block witnesses. Only Republicans voted for the rules of the trial. And, likely, only Republicans will vote to acquit. They couldn't convince one Democrat to go along. So shut the fuck up about the "partisan" impeachment vote in the House.

    A crescent Earth rising over the Moon, seen from Apollo 14 on February 6, 1971. Not as famous as the Apollo 8 Earthrise, but this one has such an eerie beauty.

    For all those wondering why the 'Medieval Warm Period' does not look warm, it is because the evidence suggests it was NOT a globally coherent event. Please update your understanding. (See: or )
