Summary

We seek the Science of Sight on this week's Naked Scientists, discovering how deep sea fish use clever bioluminescence and biological mirrors to cope with the darkness of the deep. We hear how our brains choose what sights to pay attention to, and what a bees brain can teach us about how we see optical illusions. Plus, salt-tolerant GM crops, statins stalled by sluggish blood and how the turtle got it's shell. In Kitchen Science, we fool our eyes into seeing confusing colours... Like this podcast?

and turn them into a one-hour rap show and that's all on the way then.

Thanks Chris. Also this week we're looking into the science of vision.

We'll be exploring the deep ocean to find out how some fish

become equipped with their own underwater search lights that emit special lights that only they can

see. We'll also be hearing how the brain decodes what the eyes are seeing as well as

experimenting with our own color vision to change the way that we can see colours.

And no LSD needed or any other hallucinogen for that matter. It's actually a very cool experiment.

1:13.4

If you want to have a go, all you need is some coloured plastic that you can have a look through.

1:17.7

We'll show you how to do the experiment later.
