Your next house could be built with dirty diapers

Johnny Mac discusses scientific and mathematical discoveries such as a new 'Einstein' shape – a 13-sided figure dubbed 'the hat' – that can tile a flat surface without repetition. Two heartwarming human interest stories are also included: Petra Jenny's Amelia Air, which helps transport rescued dogs to safe shelters, and Daniel Durek's successful pottery studio, Danny D's Mud Shop, built up from an Instagram experiment. Also highlighted, Stacey's leap of faith into gardening as a therapeutic sanctuary while her husband fights lung cancer, and an innovative approach from Japanese scientists who are using recycled diapers to replace sand in the concrete production process.
