Stronger Than Steel: Spider Silk DNA and the Quest for Better Bulletproof Vests, Sutures, and Parachute Rope

By Bridget Heos | Illustrated by Andy Comins

People have always marveled at the durability of spider webs. The strongest spider silk is five times stronger than steel! In this thrilling new addition to the Scientists in the Field series, Bridget Heos takes readers to the office of scientist Randy Lewis. In what sounds like science fiction, Lewis injects spider DNA into goats, then extracts what he needs from the goat’s milk to make artificial spider silk, a nearly indestructible fiber that doctors might someday be able to use to repair or replace ligaments or tendons in the human body. An enthralling exploration of modern genetics with plenty of incredible full-color photographs!
