A group of researchers from Sweden has unlocked one of nature’s biggest secrets. The scientists worked out how spiders __________ (1) such strong silk when they spin their spider webs. The silk that spiders spin is incredibly strong and is tougher __________ (2) steel. For decades, scientists __________ (3) been researching what makes the silk so amazing. Finally, researchers from Sweden’s University of Agricultural __________ (4) and the Karolinska Institute have found the answer. They found that the materials for webs are stored in a spider’s silk gland as protein. The gland has a level of __________ (5) that helps to make the protein into very strong silk. The researchers copied this process to make enough artificial spider-web silk to __________ (6) for one kilometer.
The new artificial silk might be very __________ (7) to humans. Doctors are interested __________ (8) it to use for stitches. They also think it can help the skin recover after a burn. Some doctors believe the new silk could replace __________ (9) ligaments in the body. Airplane manufacturers and makers of protective clothing also see many uses for the new silk. Senior researcher Anna Rising spoke about __________ (10) important the discovery could be. She said: “This is the first successful example of [copying] spider silk spinning. In the future, this may allow industrial production of artificial silk for bio-material applications or for the manufacture of advanced textiles.” The silk could become an important new material for us in the future.
