"While not positive,  I would strongly suspect this article was intended to boost sales of Vaporizers.  Unfortunately this technique is very common.  Just things I notice in the wording, and data not being front and center."

I would not think that Professor Ratnieks or the University of Sussex are interested in the sale of vaporisers!  The idea is ludicrous.
