       | The TL;DR is that this paper claims to have found evidence for
       | quantum effects in microtubules, lending credence to (though by
       | no means providing proof of) Roger Penrose's theory that
       | consciousness is a quantum phenomenon.

       | It's hard to buy that their proposed stories are the simplest
       | explanation for these few measurements. Much more boring
       | phenomena can influence QY. e.g. simply occluding fluorophores
       | from the bulk solvent can have a huge influence on QY.
