We took full advantage of our friend Katie Novotny (@katienovotnyyyyy) stuck at home recovering from surgery to get her back on the show! Her special Son of Your Dreams is free to stream on YouTube right now!

We talk about a supersonic trebuchet! A new fecal transplant story, this time for food allergies! And also if your microbiome's linked to psychopathy! Plus massively long-lived sturgeon! How other sturgeon get it on! Musician Slash getting his own snake species! How the number of species is calculated, with a bit of help from our buddy Matt Parker! And fake mermaid science!

In the Patreon bonus, there's some scientific proof of cats being dicks.

Chicago/NY comedian Luca Ferro (@lucaferrocomedian) joins the gang to talk about Dolphins using tools! And having names! Plus monkeys falling for (and "falling for") Monkey AI!

Plus in the Patreon bonus ep we find out about a newcomer to the carnivorous plant club.
