b'Brightening up the darker corners of your science knowledge this week are Chris, Phil and Kat, who look at colour-blindness in dogs, harnessing heat energy from the centre of the Earth, how glow in the dark motorbikes could save lives, and the erasable tattoos that wipe away the memory of the ex we would rather forget... Also on the show, Ron Hale-Evans talks about ways to improve memory, Michael Stebbins reveals how his book Sex, Drugs and DNA aims to fight back against those who stand in the way of science, and Anna Lacey learns to play the wine glasses in Kitchen Science.
