Quantum Leaf? Algae Use Physics Trick to Boost Photosynthesis Efficiency

The primary reactions in photosynthesis—the first steps in plants' conversion of sunlight energy into energy stored in carbohydrates—are incredibly efficient. And in a new study in Nature, chemists reveal that they may have found part of the reason why: quantum mechanics. A couple years ago, scientists first showed in bacteria proteins that the electrons were moving according to a quantum mechanical phenomenon called coherence, rather than abiding by the classical laws of physics. But where those early experiments
