Again, something I've posted about in the past and which interests me greatly. Not only does there appear to be an element of quantum coherence in photosynthesis (one of the most important life-sustaining processes) - see: below - but quantum effects are also believed to underpin and enhance DNA's biological functionality.
“"We studied tiny single-celled algae called cryptophytes that thrive in the bottom of pools of water, or under thick ice, where very little light reaches them,” says senior author, Professor Paul Curmi, of the UNSW School of Physics.
“!Most cryptophytes have a light-harvesting system where quantum coherence is present. But we have found a class of cryptophytes where it is switched off because of a genetic mutation that alters the shape of a light-harvesting protein.
“!This is a very exciting find. It means we will be able to uncover the role of quantum coherence in photosynthesis by comparing organisms with the two different types of proteins.”"
