Naked Science Q & A and the World of Chemistry

With a new year comes a whole new stack of science questions to challenge Dr Chris, Dr Dave and Dr Kat. This week they explain where the sand in the Sahara comes from, whether mirrors can reflect x-rays, if it is dangerous to live near a phone mast, and whether splitting water could solve our energy problems. We are also joined by the editor of Chemistry World, Dr Mark Peplow, who talks about labs the size of a postage stamp, nanoparticles in exhaust fumes, and how putting milk in your tea might not be such a good idea, and sticking with chemistry, Dave Ansell discovers which household liquids make dirty pennies look like new. In the fourth part of our series on science and colour, Anna Lacey finds out how wearing red could turn you into a world-class sportsperson.
