Getting to grips with graphene
Hundreds of times stronger than steel, transparent, an excellent electrical conductor and weighing next to nothing, graphene is hailed as a wonder material. But what is it doing for us now? And where will it take us in future? This week graphene goes under the microscope. We hear how industry can mass produce it, we uncover how it can clean up air in cities, produce the world's fastest lasers, revolutionise communications and boost the power of computers. Plus, news of how Earth's earliest life reproduced, how to regenerate human organs, and why animals have different shaped pupils...

Scientists have discovered a trigger for the regeneration of
skin, hair or organs in humans. This could be used to help
victims of burns.
Researchers have tracked down the genetic factors that
lead to the onset of Huntington's disease, to deduce

Researchers have discovered the first example of
reproduction in complex life, in an organism called
Fractofusus, 565 million years ago.
Carnivores have vertical-shaped pupils, but herbivores have
horizontal pupils. Scientists have now discovered why.
Bonobos can communicate just like human babies, by using
sounds with different meaning depending on the context.
Graphene was first isolated in 2004. Since then we have
heard the hype, but what actually IS graphene? And why is
it so exciting?
Graphene has some impressive properties, but how do we
actually make it commercially? What happens in a

doing for us right now? What are the current uses of this
Graphene has some truly exceptional properties. The real
killer application will be in something totally novel, but what
will it be?
