BBC - Earth News - Honeybees sterilise their hives

BBC - Earth News - Honeybees sterilise their hives: "Honeybees sterilise their hives with antimicrobial resin, scientists have discovered.

In doing so, they give the whole colony a form of 'social immunity', which lessens the need for each individual bee to have a strong immune system.

Although honeybee resin is known to kill a range of pathogens, this is the first time that bees themselves have been shown to utilise its properties."
