      • Ep. 154 Venom Pt 1: Bites and Stings and Ouchie Things

        Hi Everyone! Welcome to the first episode of our series on venom! We previously discussed toxic stuff, and venoms are a specific subset of toxic things that are introduced to the body by bite or injection rather than getting swallowed or inhaled or whatever. In this first episode we give a breakdown of the different kinds of venom, and in the following two episodes we'll talk about specific venomous animals!

            In our first episode on the topic, we introduced the idea and definition of doping. In this episode we dive into blood doping, gene and cell doping, and a little debate about whether doping really is all that bad.

                We took a break from our series on poisons, but we're back now to chat about organic poisons! No, not like pesticide-free poisons, organic in this context just means they're molecules that have carbons and hydrogens in them! So no more chatting about metallic poisons, we're going to move on to stuff like hemlock!

                I promise Nathan doesn't say 'whey' weird the entire episode, it just takes a bit for him to stop. This week's episode is about whey protein! What is it? Does it actually provide any benefit over any other protein?

                Hi Everyone! This is the first episode in a periodic series we're going to do called 'side quests'. Sometimes we come across science stories that aren't quite enough to do a full episode on, but are interesting and fun to talk about! So from now on we'll occasionally present them as a series of shorter stories within an episode! In this episode, we'll discuss a competitor of Louis Pasteur, a high school that appears to be the center of a cluster of brain tumors, and a historical example of unethical experiments on prisoners incarcerated in the USA.

                  Hi Folks! Part three of our poison series is on arsenic, the king of poisons and the poison of kings! Arsenic had a long history of being used to kill nobles, but after a reliable test for arsenic was developed in the 1800s it got a lot less popular for killing people. But in true human fashion, we continued to use arsenic for all kinds of things!
