We speak to Simblified fan (!) and microbiologist Avraneel Paul on a whole bunch of things related to what happens inside our body! Viruses and bacteria, how vaccines work, how those WBC badasses keep us safe, and so on. Along the way, we also speak about exciting advancements like CRISPR, and explore philosophical questions like whether Covid has changed the field... And what a day in the life of a scientist looks like. There's loads of trivia, loads of simblification and a few bad jokes as well in this two-part episode. We hope you like it and have renewed appreciation for scientists (and your body!) after it!
