El Nino, Sphagnum moss and peatlands, Inside Cern, Measuring air pollution with iPhones

Tracey Logan investigates the latest El Nino warnings, using beads of sphagnum moss to restore peatlands, the search for the Higgs boson and measuring air pollution with iPhones.

Tracey Logan investigates the latest science news. Roland Pease reports on recent warnings that we're heading for one of the most severe El Ninos on record which could distort weather patterns around the world. Spongey sphagnum moss provides a protective layer to peat lands but in the bogs of the Peak District industrial and urban air pollution has killed nearly all the moss. This means the peat lands can erode releasing tonnes of ancient carbon. Tracey talks to horticultural ecologist, Neal Wright about his technique for creating tiny gel beads of sphagnum moss to spray on the moors to help restore their peat lands back to health. Marnie Chesterton talks to John Butterworth about his book, 'Smashing Physics' which is another short-listed entry for the Royal Society Winton book prize. He talks about the highs and lows of the discovery of the Higgs Boson and why CERN might soon be creating dark matter. Tracey talks to Toby Shannon, from the Institute of Physics about the International Year of Light citizen science project to measure air pollution using an iPhone. Details on how to take part here:
