Biology uses quantum effects.

When I first saw this article by Jim Al-Khalili and Johnjoe McFadden, my skeptical reflex kicked and I was, well, skeptical.  Often when quantum mechanics gets mentioned with biology, it’s questionable material.  But I’ve seen enough of Al-Khalili’s other work, and as … Continue reading
