49Outlook for researchMan-made fibers need to be processed at hightemperature, while spiders and silkwormssynthesize their silk in a mild condition. We cansynthesize the artificial silk by mimicking thenatural spinning system and contribute to usesilk as a structural material in our daily life.Outlook for students after graduationI would like to share the excitement of tacklingthe science of nature, from the study of spiderand silkworm silk. You will make hypothesis andperform experiments to proof the hypothesis.Hopefully, you will exert yourself in society fromyour research experiment at Shinshu University.Associate ProfessorYAZAWA KenjiroDepartment ofApplied BiologyAssociate Professor Yazawa got hisph.D at Tokyo Tech. and came to hiscurrent position after working as apostdoctoral researcher at Yamagatauniversity and RIKEN in Japan. Hespecializes molecular biology andpolymer science. His final aim is toreveal the mechanism of spinningsystem of spiders and silkworms.Spiders transform silk solutions into fibers in their glands.Spiders are fixed between sponges with their legs inside the sponges toextract their silks. We feel that the silk is shiny and tough .Silk is used as a structural material in nature such as a lifeline ofspider and a shell of silkworm. The thickness of spider silk isapproximately one tenth of human’s hair. The spider silk with3-mm thickness can support a man with 60 kg. Silk seems veryattractive when used as structural material, however,it isdifficult to synthesize an artificial silk that has both strengthand extensibility like native silk. Spiders and silkworms areknown to possess sophisticated spinning mechanism. I wouldlike to share mysteries in the natural spinning systems inspiders and silkworms and take advantage of the system tosynthesize artificial silk for industrial applications.How can spider and silkworm spin such a tough silk?
