Naked Science Question and Answer


Chris Smith

Kat Arney

Phil Rosenberg

Brightening up the darker corners of your science knowledge this week are Drs 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 erasable tattoos that wipe away the memory of the ex we'd rather forget... Also on the show, Ron-Hale Evans talks about ways to improve memory and creative brain power, Dr Michael Stebbins reveals how his book Sex, Drugs and DNA aims to fight back against all those standing in the way of science, and Anna Lacey learns to play the wine glasses in Kitchen Science.

I'm curious about this digital era we've gone into. If you watch the television on digital signal, the clock that they show, especially on breakfast television, has a slightly different time than real time. This is because of the signal having to go up to the satellite and come back down again. I wondered if there was a way of solving this?
