Yeast is everywhere. We use it to make bread and beer but it’s a fungus with its own biology. Science is turning to yeast once again to make wonderful things for us. We can bioengineer it to turn its natural processes into building compounds that humans can use, like medicine. That’s the research being done by this episode’s guest, Asia Vighi, a PhD student in Bioengineering at McGill University. Katie and Vinny talk about heat sensing and how babies feel pain.
