The rare earth elements are the focus of the latest instalment in Business Daily's exploration of the real basis of the world economy - the basic building blocks of everything in the universe, the chemical elements.

And it's not a short list we cover: Lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, turbium, dysprosium, holmium, erbium, thulium, ytturbium and lutetium.

You may not have heard of most of them but some have insinuated themselves deep into modern life. We'll be finding out the extraordinarily range of uses to which they've been put, as well as the big problem: The supply of these is overwhelmingly dominated by China.

We'll be hearing from Professor Andrea Sella of University College London, Jack Lifton of Technology Metals Research, the journalist Cecile Bontron who provides a first-hand account of the Chinese processing plant at Baotou, as well as Henrik Stiesdahl and Rasmus Windfeld of Siemens' wind turbine division.
