Getting to grips with graphene

Graphene (c) Dr Thomas Szkopek

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...

  • 01:02 - Organ regeneration trigger found

    Scientists have discovered a trigger for the regeneration of skin, hair or organs in humans. This could be used to help victims of burns.

  • 06:11 - Huntington's gene links

    Researchers have tracked down the genetic factors that lead to the onset of Huntington's disease, to deduce at what age it will develop.

  • 11:28 - How the first life reproduced

    Researchers have discovered the first example of reproduction in complex life, in an organism called Fractofusus, 565 million years ago.

  • 17:18 - Why cats have vertical slit pupils

    Carnivores have vertical-shaped pupils, but herbivores have horizontal pupils. Scientists have now discovered why.

  • 21:47 - Bonobo language

    Bonobos can communicate just like human babies, by using sounds with different meaning depending on the context.

  • 26:42 - What is graphene?

    Graphene was first isolated in 2004. Since then we have heard the hype, but what actually IS graphene? And why is it so exciting?

  • 34:06 - Making graphene industrially

    Graphene has some impressive properties, but how do we actually make it commercially? What happens in a graphene-making factory?

  • 39:44 - Applications of graphene

    We have heard all the hype, but what is graphene actually doing for us right now? What are the current uses of this 'wonder material'?
