The paper was published on the Proceedings of the Royal Society B today, whynot. (Some journalists had early access subject to a publication embargo.) A quote from the paper:

"Queens were randomly allocated to one of three treatment groups: control, 1 ppb thiamethoxam (low dose) and 4 ppb thiamethoxam (high dose)."

Why would you jump to the conclusion that there might be a basic, fundamental error in a peer-reviewed paper appearing in a solid journal, a paper you hadn't even read?
