For the first time, researchers have observed how just one particle of light can trigger photosynthesis in bacteria — finally revealing the first step of the crucial process.
I’m not entirely sure what they found from the article, because I thought I learned something about photon absorption in the chlorin ring way back in undergrad, but regardless, the idea that a single photon is sufficient to trigger the photosynthetic process is absolutely fascinating, and the idea that we can track that is even more so.
