It’s almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists reporting in ACS Nano ("Overexpressed Artificial Spidroin Based Microneedle Spinneret for 3D Air Spinning of Hybrid Spider Silk") have made their own version of fake spider silk, but this one consists of proteins and heals wounds instead of haunting hallways. The artificial silk is strong enough to be woven into bandages that helped treat joint injuries and skin lesions in mice.
