It is no secret that nature’s process of photosynthesis—which harnesses the energy in sunlight—is astonishingly efficient. And researchers have known for years that quantum mechanisms play a role in the protein antenna farms deployed in these marvelous molecular machines. Now new research, based on a experimental technique that tracks these proteins at the femtosecond level (there are a million billion femtoseconds in a second), elucidates some of these quantum mechanisms and, as usual, the results are surprising.
