• We gave the impression that Teodor Silviu Balaban and his team are attempting to mimic the light-harvesting mechanisms of plants or deep-water algae (11 November, p 30). Balaban is actually attempting to create artificial versions of the simpler chlorosomes found in early photosynthetic bacteria. We also erred in his affiliation: Balaban is at the Institute of Nanotechnology at the Karlsruhe Institute of Technology.
