The impact of light on the human brain, and do moths bite?

Light is essential for plants to grow, but what do we know about how it affects the human brain? Does light reach it or does the skull block it?

How does light affect the human brain: does it reach it or is it blocked out by the skull? Can people survive a lifetime without light? 

A listener wants to know what the Pioneer and Voyager space programmes can tell us about the movement of man-made objects in space, and we find out whether anything can escape the clutches of a black hole.

There's more on the fate of our insect population and the story of a moth that bites. And fans of magpies will be pleased to hear how one listener thinks that they play a key part in the story of evolution! 

Answering the questions this week are the ecologist Dr Lynn Dicks, the astronomer Dr Carolin Crawford and the biotechnician Professor Denis Murphy. All under the watchful eye of presenter Richard Daniel.
