This week Mattie gets excited about inherited traits that don't have a clear genetic cause, cellular memory, and we both reach out to some mad scientists with some unethical experiments. Austin talks about the time some Samurai went to New York City and became the talk of the town. we also get bummed out about the passing of John Lewis. If you haven't yet, read March written by John Lewis and Andrew Aydin, and illustrated and lettered by Nate Powell.
