Lots of "migth be" and "seems to be" in that article. I don't think we understand it or can replicate it in the laboratory.

Are you claiming that lack of current understanding proves a fundamental impossibility of doing so?

Certainly not! Lack of understanding of the complete universe is why we don't know if God exists or not. We don't _now_ know how to define and measure love in the lab, so there are likewise probably other things that also cannot be measured and detected physically (at least at the present time).
