Repairing the Retina and Spinal Cord

retina (c)

Repairing damage in the nervous system is incredibly challenging, but our guests this week have some promising solutions. Consultant ophthalmologist Dr Robert MacLaren from Moorfields Eye Hospital and colleagues at University College London have discovered a way to encourage the growth of photoreceptors in the retinas of blind mice, and Professor Geoff Raisman from University College London will discuss his research into spinal cord repair. In Kitchen Science, Derek Thorne and Hugh Hunt take a closer look at the aerodynamics of a ping pong ball.

  • Why are faint lights brighter if you don't look at them?

    A car across the street has a flashing blue security light that's very faint when you look straight at it. But when you look at it sideways, the blue light's much brighter. Why is this?

  • Why can your retina detach?

    If the retina is grown on the back of the eye, as a part of the back of the eye, why does it seem to detach so easily, under different conditions?

  • Can you mend a detatched retina?

    I had a detached retina in 1980. Although it was repaired in 1982, would it be possible to make it better than it is now? I currently have monocular vision.

  • Why can't you fix al llazy eyes?

    He has a lazy eye. It can't be rectified because it's something to do with the brain not connecting with the eye properly. He - why can't that be fixed, in general terms?

  • The Aerodynamics of a Ping Pong Ball

    If you've ever wanted to make a ping pong ball levitate in mid air - this kitchen science is for you. This week Derek and Hugh Hunt are with Nick and Christian from Norwich School trying to investigate how we can make something levitate without using dodgy magic tricks!
