Spider silk is one of the most versatile and high-performance natural materials, boasting over 40,000 spider species each able to spin up to seven unique types. Some silks can stretch to more than twice their original length, while others rival or surpass Kevlar in toughness. The secret lies in a single gene family that evolved over 380 million years, leading to an amazing diversity of silk proteins. These remarkable fibers are fueling innovation in medicine and technology, from artificial tendons to lightweight armor.
