Water helps assembly of biofibers that could capture sunlight

A new study has shown water can serve a previously undiscovered role to help micelles coalesce to spontaneously form long fibers. The study could help scientists to understand how light-harvesting molecules are incorporated into the micelle fiber as it assembles, which would be a key step to understanding some forms of artificial photosynthesis.
