Spacegypsy rated 9 months ago- Sunlight absorbed by bacteriochlorophyll (green) within the FMO protein (gray) generates a wavelike motion of excitation energy whose quantum mechanical properties can be mapped through the use of two-dimensional electronic spectroscopy.

Remarkably Long-Lived Wavelike Quantum Coherence Plays An Important Part In Photosynthesis

- Quantum mechanics apparently are involved in the incredibly efficient process of photosynthesis. Apparently when light is converted to energy for the plant, wave-like structures are formed that explore all possible paths of the conversion without the risk of the loss of energy. In effect, the transfer of energy is efficient because the wave-like structures that seek the best path for energy flow can retreat without risking a loss of energy.
Though the possibility that the process might use quantum oscillations was suggested 70 years ago, this is the first time scientists have actually been able to observe the process. This is an amazing discovery that could eventually lead to a quantum way for man to efficiently derive energy from the sun and end a large part of the pollution that plagues mankind.
From the page: "Electronic spectroscopy measurements made on a femtosecond (millionths of a billionth of a second) time-scale showed these oscillations meeting and interfering constructively, forming wavelike motions of energy (superposition states) that can explore all potential energy pathways simultaneously and reversibly, meaning they can retreat from wrong pathways with no penalty. - Quantum mechanics apparently are involved in the incredibly efficient process of photosynthesis.
