Episode 3 of Interronauts and we’re talking about the uninvited microbes that stumble into our guts, how you can store Amazon gift cards on DNA, the mutations behind mirror movement disorder, and our 3D printing of a titanium sternum and polymer tissue with Anatomics. We also speak with Michelle Trautwein about her new project ‘Arthropods of Our Homes’ to catalogue the Australian arthropods we share our homes with. Enjoy the show, why don’t you.

This week we spoke with Michelle Trautwein from the California Academy of Sciences, who runs the Arthropods of Our Homes project, which catalogues the proportions of arthropods we share our homes with. About the project: “For all of human history, insects and their relatives (collectively known as arthropods) have been our constant companions. We compete with them for food, use them as resources, and – whether we like it or not – share our homes with them. Many species, both common and unfamiliar, have been evolving with us for millennia. The Arthropods of Our Homes project explores the arthropod diversity of our homes. We are interested not only in what species are present, but also how the characteristics of your home and lifestyle may affect the insects, spiders and other arthropods that come to dwell there.”

Bone, cartilage and tissue; we’ve cracked the trifecta (and it’s made of titanium and plastic)

“We’ve been quietly working away in Melbourne on something big. The big trifecta of a bone, cartilage and tissue implant. The first of its kind. More specifically, a 3D printed titanium and polymer sternum to suit individual patients. Feeling like you’ve already heard about this? That’s because in 2015 we partnered with Anatomics to 3D print a sternum and rib implant for a Spanish cancer patient,” from our blog. Learn more about the break-through here.
