"For me science isn't a subject, it's a perspective. There are fascinating scientific aspects to everything from ancient history to the latest gadgets, outer space to interior decorating; and each week on The Material World we try to reflect the excitement, ideas, uncertainties, collisions and collaborations as science continues its never-ending voyage into the unknown".

Flood Warning
The floods in Yorkshire and elsewhere are a reminder of how vulnerable we are to quirks of nature. An unusual pattern of storm clouds is all it takes to bring torrents into people鈥檚 front rooms. 10,000 homes are thought to have been affected, and insured losses are said to be at least a billion pounds. And with climate change, extreme storms are expected to become more common. Quentin hears from Professors Ian Cluckie and Anthony Illingworth about two major projects intended to give us fast and reliable early warning of impending floods.
Fuel Cells from Chocolate and Road Dust
Hydrogen fuel cells have been much touted as the major energy carrier in a post-fossil fuel economy. But, whilst they can generate clean electricity locally with only water vapour as exhaust, exactly how to source the ingredients sustainably is a subject of concern for many climate thinkers.
After a chance听encounter, exploration geologist Dr Hazel Prichard of Cardiff University and Prof Lynne Macaskie of Birmingham鈥檚 School of Biosciences,听combined forces to pursue a very unusual type of recycling.
Hazel tells Quentin about her work on tracking platinum in the dust left on roads by catalytic converters on cars and how it can be harvested by a strain of E. coli bacteria (not the famous, dangerous strain). And as Lynne describes - the bacteria are taken from a biosynthetic process that makes pure hydrogen from chocolate waste.
