The effect of multiple light excitation events on bimolecular photo-induced electron transfer reactions in liquid solution is studied experimentally. It is found that the decay of fluorescence can be up to 25% faster if a second photon is absorbed af

Many animals sense the Earth's magnetic field and use it for navigation. It has been proposed that a light-dependent quantum effect in cryptochrome photoreceptor proteins residing in the retina allow for such an iron-free spin-chemical compass. The p
