Spider silk spinning field, the spinneret apparatus of an adult "Araneus diadematus" (garden cross spider) consists of the glands shown below. Similar multiple gland architecture exists in the black widow spider. In order to artificially synthesise spider silk into fibres, there are two broad areas that must be covered. These are synthesis of the feedstock (the unspun silk dope in spiders), and synthesis of the spinning conditions (the funnel, valve, tapering duct, and spigot). There have been a number of different approaches. The molecular structure of unspun silk is both complex and extremely long. Though this endows the silk fibres with their
The Unicorn in the Garden 1950 film "Harvey" contains a scene depicting characters at a psychiatrist's office, where Veta is committed to the institution instead of Elwood. Dr. Richard Lenski, leader of the "E. coli" long-term evolution experiment, made an allusion to the story in a widely disseminated response to Conservapedia founder Andrew Schlafly (who expressed doubt Lenski found an evolutionary beneficial mutation in "E. coli" bacteria): "In other words, it's not that we claim to have glimpsed 'a unicorn in the garden' – we have a whole population of them living in my lab!"
