In the context of honey bee diseases, Dr Maleszka says "since we now can produce queens in vitro (in the lab), our work has the potential to be used for producing 'super queens' with specific characteristics or disease resistant genotypes."

It is amazing how a thick, creamy secretion can bring into existence complex life and culture.
