    Ep. 63 The Brain's Bouncer: The Blood Brain Barrier

    We did a twitter poll and the people have spoken! You folks want to hear about the "Blood Brain Barrier"! But what is it, besides great alliteration?! The blood brain barrier is a lot like a bouncer for the exclusive dance club that is your brain -- but who is allowed in? How does one get in? And on a cellular and protein level, who are the actual bouncers that keep us out? Next week we will get into some of the details on diseases and drugs and their impact on the blood brain barrier, so tune in next week too!

    Ep. 59 Fungus: The Good, The Bad, and The Zombie

    Ep. 59 Fungus: The Good, The Bad, and The Zombie

    This week we're doing our second episode about Fungi! Last week we talked about what fungi even are in a broad sense. This week we cover symbiotic and pathogenic fungi, like the famous Cordyceps fungi!

    Btw near the end of the episode Sean mentions carpenter ants farming fungi -- they don't. That's more like leafcutter ants. Carpenter ants *do* farm aphids, but that shit is different.

    Ep. 58 Fungus: What Even Is It?

    This week we're talking about Fungi! They used to be grouped in with plants, then got their own Kingdom... But what do we think about them now? What even are fungi? How can a group contain both little yeasts used for baking and mushrooms that can get you high? And how have we used them to make huge leaps forward in biological sciences? Next week we'll cover symbiotic and pathogenic fungi, like the famous Cordyceps fungi!
