Meet the detector elephants that could start saving lives

Some scientists from the University of the Witwatersrand in South Africa have conducted research with elephants that may soon save lives.

In the video below, a researcher explains that there are stories of the gentle giants avoiding minefields in Angola through olfaction, or their sense of smell.

They believed that the elephants recognised the smell of TNT in explosives, so the US Army Research office asked the zoologists to conduct some scientific research to see if it was true.
