Physicists have found the strongest evidence yet of quantum effects fueling photosynthesis. Multiple experiments in recent years have suggested as much, but it's been hard to be sure. Quantum effects were clearly present in the light-harvesting antenna proteins of plant cells, but their precise role in processing incoming photons remained unclear. In an experiment published Dec. 6 in Proceedings of the National Academy of Sciences, a connection between coherence—far-flung molecules interacting as one, separated by space but not time—and energy flow is established.
"There was a smoking gun before," said study co-author Greg Engel of the University of Chicago. The new findings are the latest in a series that have, piece by piece, promised to expand scientific understanding of photosynthesis, one of life's fundamental processes. Then came observations of coherence in antenna-protein chlorophylls from green sulfur bacteria. Intermission: The Robots Can Now Fly and Juggle at the Same Time - Technology.
