Science, light harvester

Science goes deeper inside the mystery of light. In the last cover (29 May 2015), proteins inside the chloroplast of a plant cell, including the supercomplex of photosystem I and light-harvesting complex I, work together to turn light into chemical energy. A high-resolution crystal structure by Qin et al. reveals the positions of chlorophylls a and b (shown in the foreground as circular and hexagonal disks, respectively) and carotenoids (shown in orange). Light plays an important role also in neuroscience research, especially in the so call optogenetics.
