  • 01:02 - How do I smell?

    Stuart Firestein, Professor of Biology at Columbia University, explained to me how our sense of smell works, and why itís so important

  • 09:16 - Gene therapy for blindness

    Researchers have carried out a small but successful trial of gene therapy for a type of blindness.

  • 14:41 - Genes and schizophrenia

    US researchers have pinpointed new genetic variations linked to the psychiatric condition schizophrenia

  • 15:50 - Sequencing the coral community

    Japanese researchers have analysed the genes in a whole coral community, including the corals and the organisms living on them

  • 17:00 - Scent of a maggot

    At the University of Manchester, Professor Matthew Cobb and his team are studying how maggots smell things.

  • 24:39 - How does the polymerase chain reaction work?

    Polymerase Chain Reaction - how does it work? I've read a brief explanation on Wikipedia, but it seemed more to describe the heating cycles scientists go through without, explaining how copies of DNA are produced and amplified.

  • 27:49 - Gene of the month - Escargot

    Our gene of the month is Escargot, named after the French word for snail, but also known by the less exotic name Fleabag.
