I was on Minnesota Public Radio's morning show The Daily Circuit today—along with Ivan Semeniuk, chief of correspondents for the journal Nature—talking about the Curiosity rover, human evolution, and dealing with the big unknowns in science. You can listen to that segment online.
But right at the end of my bit, as I was packing up my stuff to leave the studio, I heard the next segment on the show, and it was AWESOME. Ask a Neuroscientist is, precisely, reader questions answered by a neuroscientist.
