About this episode
After 41 Indian miners were happily rescued last week, Unexpected Elements takes a look at how our futures might lie below the surface.
As climate change suggests more of our infrastructures need to be buried safely, and even living spaces could be cooler down there, we discuss future technologies for digging tunnels more safely and cleanly.
But tunnelling and boring could go back a long way - more evidence suggests species of dinosaurs used to to live semi-subterranean lives.
Tunnelling also happens at the very smallest scales and lowest temperatures, as observed this year by physicists at Innsbruck University. Dr Robert Wild of Innsbruck University in Austria describes quantum tunnelling - a crucial process that belies most chemistry and even the fusion of hydrogen in the sun, and which is increasingly becoming part of our electronic devices.
Also, a new technique for monitoring the rapid evolution of the malaria parasite, your correspondence including obscure sports and asteroid fantasies, and a discussion of the difficulties of hiring a panda.
Presenter: Caroline Steel, with Philistiah Mwatee and Alex Lathbridge
