Every day we get older, and whether you’re desperately resisting the march of time, or embracing the ageing process, most of us would agree we want to live as long, healthy lives as possible. We’ll be finding out how genetics research can help. Plus, making fingers with Alan Turing, growing lizard tails, and a long-lived gene of the month.

    01:01 – Prof David Gems – Healthy ageing

    I spoke to David Gems, professor of biogerontology at UCL,
    and asked him what we mean by “ageing” from a biological
    perspective.

  • Fingers (c) Dave Ansell

    09:33 – Prof James Sharpe – Making fingers

    Most of us are born with five fingers, but how do they get
    there? The answer was first put forward more than 60 years
    ago by Alan Turing.

    14:38 – How lizards regrow their tails

    Researchers have analysed the patterns of gene activity in
    regrowing lizard tails, paving the way for better regenerative
    technology.

  • Thymus (c) Tourbulence/Siebrand

    15:49 – Organs in a dish

    The day when we can grow fully-functioning organs in a dish
    have come a step closer, with a lab-grown thymus.

  • Fruit Fly (c)

    16:58 – Michael Shannack – Fat, old flies

    Michael Shannack has been studying fruit flies carrying an
    altered version of a gene called GSK3 which have longer,
    healthier lifespans.

  • Red wine (c) THOR- flickr

    28:30 – Gene of the month – SIRT1

    One of a family of genes called Sirtuins, SIRT1 is one of seven
    human versions of genes found across pretty much all
    organisms.

The Spacewalk from Hell

Space Boffins Sue Nelson and Richard Hollingham hear from the Rosetta mission’s Flight Director, Andrea Accomazzo, about choosing a landing site on comet 67P – plus Apollo astronaut and last man on the Moon, Gene Cernan, on the spacewalk from hell. Dr Lucie Green from the Mullard Space Science Laboratory and the lab’s poet in residence, Simon Barraclough, are the lively studio guests. Expect space poetry, scientific insight and a song about photons.
