I've came across the #Ologies podcast. It's a podcast where Alie Ward (the host) takes a different -ology (e.g. Corvid Thanatology - crow funerals) and interviews a scientist (or similar) who knows about said ology. I'm really enjoying it!
I can recommend based on the ones I've listened to. I'm starting from the beginning and are making my way through the backlog :)
@tsyesika looks interesting
