Stripping down science, the naked scientist.

Hello, welcome to this week's naked scientists with me Chris Smith and also with Helen Scales.

Hi Helen. Now on this

week's program how scientists have discovered a suicide switch for

bacteria and researchers think that it could hold the key to some powerful new

antibiotics so we'll be finding out about that shortly.

Also how soap suds are preventing fish from forming shoals.

Apparently the detergents they use stop them smelling each other,

and also beating off sunburn with a dose of, guess what, broccoli.

Scientists have discovered that it can ward off the effects of UV rays, so that's all

on the way.

Also under the microscope this week is the science of stem cells, chimeric embryos and cloning technology.

We'll be talking with Ian Wilmot, the scientist who created Dolly the Sheep

and the stem cell researcher Roger Peterson to discover what's involved.

Plus we'll also be hearing from Ben Velsler, who's been to the Manchester Science Festival where, among other people he met this luminary who some of you might remember.
