High-speed shooting reveals protein changes during photosynthesis

[ad_1] Credit: University of Gothenburg Photosynthesis is the main source of energy for nearly all life on earth. A new study, published in Nature, provide new insights into how evolution has optimized the light-guided movements of electrons in photosynthesis to achieve near-perfect overall efficiency. Almost all life on earth has …
