On Monday, physicist (and father of the Xbox) Seamus Blackley used 4,500-year-old yeast to bake a loaf of sourdough.
He chronicled the whole endeavor on Twitter, from extracting spores from ancient Egyptian pottery straight to the finished loaf. To his surprise, thousands of people liked and shared the thread, fascinated by the intricacies of the ancient bread baking techniques that Blackley is an amateur expert in.
