Why's Graphene Great?

Graphene - a carbon lattice (c) Dr Thomas Szkopek

Graphene is the focus of this week's Naked Scientists, including how it holds the key to the super-flexible touch screen displays of tomorrow, super-light composites and the next generation of computer chips. In the news, a breakthrough in understanding Alzheimer's Disease, why glider pilots should be paying more attention to how falcons fly and why a new exoplanet has led astronomers to question current theories of planetary formation. Plus, we celebrate the first chunk of cheese to make it into orbit and ask if there's any evidence of a health benefit from wearing magnetic bracelets...
