Panto, short for pantomime, has become a staple of British Christmas celebrations but surprisingly its origins are neither British or Christmassy.

The word ‘pantomime’ comes from the Latin ‘pantomimus’, which means...

Ever had that moment when you're relishing a juicy fig, and someone drops the bomb that you might be chowing down on a wasp? Surprising as it sounds, it's true. Fig wasps do their thing by pollinating figs from the inside, but unfortunately, they sometimes get stuck in there!

This microbiota is a mix of mi...
