A team of researchers from the RIKEN Center for Sustainable Resource Science, Keio University and Kyoto University, has found that liquid-liquid phase separation (LLPS) drives the process of converting spidroin proteins to spider web fibers. In their paper published in the journal Science Advances, the group describes replicating the process of converting an internal protein to spider web fibers in their lab and how doing so allowed them to create strands of silk.
