    Ira and Flora ask the questions that we all want to know about science topics. Their wit and punny style make me laugh while I’m learning. Thanks for satisfying our scientific curiosity!

    Love the topics and the guests, but PLEASE tell them to stop the “good question” preface before EVERY single answer. I’s becoming a drinking game joke. I suspect someone coached scientists to say this but it gets to be patronizing and annoying or hear over and over again. Just share your expertise and move the conversation forward.
