Lucy was sick this morning, so Ted Dwyer filled in, and he and Alice talked all about how scientists have managed to store a piece of video within a section of DNA. Sticking with incredible achievements, they also discussed the amazing impact of Maryam Mirzakhani, an Iranian mathematician who passed away a few days ago at just 40 years of age. She was a ground-breaking mathematician who was the first woman to ever win the prestigious Fields Medal - maths’ Nobel Prize equivalent.
