Silk found in insect pupae , and in spider webs and egg casings, also has twisted β-pleated sheets incorporated into fibers wound into larger supermolecular aggregates. The structure of the spinnerets on spiders’ tails, and the contributions of their interior glands , provide remarkable control of fast extrusion . Spider silk is typically about 1 to 2 micrometres (µm) thick, compared with about 60 µm for human hair, and more for some mammals. The biologically and commercially useful properties of silk fibers depend on the organization of multiple adjacent protein chains into hard, crystalline regions of varying size, alternating with flexible, amorphous regions where the chains are randomly coiled .  A somewhat analogous situation occurs with synthetic polymers such as nylon , developed as a silk substitute. Silk from the hornet cocoon contains doublets about 10 µm across, with cores and coating, and may be arranged in up to 10 layers, also in plaques of variable shape. Adult hornets also use silk as a glue , as do spiders.
Melatonin is a hormone produced by the pineal gland that helps regulate hormones and the body’s circadian rhythm. It is being used in veterinary medicine as a natural treatment for coat loss in dogs, cats and ferrets. Researchers are not exactly sure how melatonin helps thicken and regrow fur. Some researchers think it may be the relationship between melatonin, sunlight, and the body’s circadian rhythm. Other’s feel that melatonin’s antioxidant properties help promote hair growth. Melatonin has also been shown to help a pet gain back weight after surgery, stress or illness and help with anxiety, insomnia, and noise phobias. Mink farmers have been known to use melatonin to promote thick coats in the winter.
Earlier in the day, Draymond Green appeared at the Warriors’ victory parade in a “Quickie” T-shirt , a play on Cleveland’s Quicken Loans arena and the speed with which Golden State dispatched the Cavs in this year’s finals. In an interview, Green said he was getting revenge on his good friend LeBron for wearing an Ultimate Warrior T-shirt after the Cavs beat Golden State in the 2016 Finals. He also mentioned the notorious tombstone cookies at LeBron’s Halloween party . “I was waiting on this moment,” Green said.
