I’m very interested to learn of any discoveries regarding the utilization of non-trivial quantum effects in biological systems. (I wish I could follow developments more effectively then just the occasional internet search.)
Anyway, back in April a paper in Nature appeared discussing the meaningful role quantum coherence plays in photosynthesis. Here is the press release from the research team at the Berkeley Lab. Here is a short piece in Scientific American (Access to the Nature paper requires subscription -- a related paper in Science followed in June.)
This seems like a big deal to me – this is a central topic in biology – and until now biologists incorrectly assumed only classical mechanisms were being used.
If natural selection made use of quantum coherence in this case, it seems likely we should find it exploited elsewhere by living things.
