Following the earth tremour in Johannesburg recently, we look back at the history of earthquakes in South Africa.

Doctor Alastair Sloan from UCT tells us about seismology and how citizens can be involved in the study of earthquakes. Then associate professor Chris Roth at the University of Pretoria’s Engineering department shows us just how SA’s buidlings are prepared for earthquakes.

In the news we find out how dogs see humans and why some people are night owls. This week’s UnScience tells you about monkeys flossing their teeth.

The Science Inside is presented by Elna Schütz and DJ Keyez. Our production team is Matthew Law, Gabriel Chemhuru, Moniq Lyons and Michael Venter, with technical production by Kutlwano Serame.
