Bad taste, arsenic and blue skies ...

Chillis contain the substance capsaicin which gives them their burning quality. Now scientists are finding out how it works.


We explore the discovery that super hot, burning chillies can be used for pain relief; how holes in the asteroid belt show scientists how the planets got to be where they are; why things smell the way they do; the new clue into the cause of Alzheimer's; how our reaction to an unpleasant taste is the basis for our reaction to things we find objectionable; how arsenic exposure can be monitored in your toenails. Plus in 'Stuff and Non-Science', are the sea and the sky blue because they reflect each other?
