"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".

The Problem of Used Tyres
An E.U. Landfill Directive comes into effect on July 16th which will ban not only whole tyres but also shredded tyres being dumped in landfill sites.听 Roughly 80% of tyres are broken down for further use. For instance听when burnt in kilns to make cement.听 However there are environmental issues; more energy is required to create this process than the amount of energy produced.听 Used tyres听can also be used for 'material recovery': kids' playgrounds or carpet underlay. With some 30 million used tyres in the UK every year what happens to them at the end of their lives? Jamie McWhir who's worked as a tyre engineer with a Formula 1 team discusses this with Quentin Cooper and John Campbell, Business Development Director of Vellco, a UK company that collects over six million tyres each year for recycling.
Synthetic Biology
The hot topic in science research right now is synthetic biology.听 Engineering principles are applied to biological components and scientists are finding a huge potential for new innovations.听 The E. coli camera that uses genetically engineered bacteria that metabolise sugar only in the absence of light,听allowing the development of a high resolution black and white image.听听Professor听Edward Marcotte at University of Texas at Austin,听an advisor to the students who developed the E. coli camera,听discusses synthetic biology with Quentin Cooper and science writer, Philip Ball.
