Wits team shows how lightning shapes mountains

South African scientists at Wits University in Johannesburg have been featured in National Geographic for their "shocking" work that shows that it is lightning - rather than ice and heat - that is the main force shaping the Drakensberg summits.

Wits unit aims to demystify lightning

Researchers at Wits University in Johannesburg - the self-proclaimed lightning capital of the world - are conducting experiments to understand how the human body reacts to a strike, something they hope will help reduce the number of lighting-related deaths. Their work has been featured by National Geographic.
