We knew that Prince Charles talks to plants, but it now seems that plants talk to plants.  An experiment carried out at Exeter University has established that when a cabbage plant has one of its leaves cut off, it emits a gas - it seemed for no apparent purpose.  But now it has now been shown that other cabbage plants nearby pick up this signal and take measures to protect themselves.  Of course, there have always been people who claim to hear plants screaming when they are uprooted - perhaps they weren't quite so barmy after all?  And then do you remember Bill and Ben...?
