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

Bridget Heos (Author) Andy Comins (Illustrator)


In Stronger Than Steel, readers enter Randy Lewis' lab where they come face to face with golden orb weaver spiders, transgenic alfalfa, silkworm silk, and goats, whose milk contains the proteins to spin spider silk--and to weave a nearly indestructible fiber. Learn how this amazing material might someday be used to repair or replace human ligaments and bones, improve body armor, strengthen parachute rope, and even tether an airplane to an aircraft carrier! Readers explore rapid advancements in the application of genetic medicine and their potential to save and improve lives while considering the crucial ethical concerns of genetic research. A timely addition to the acclaimed Scientists in the Field series.

"Move over, Spider-Man. . . . Abundant photographs and a lively narrative make the topic accessible and almost lighthearted, and Heos lays groundwork for readers with a basic introduction to DNA and gene theory."
--Publishers Weekly, starred review

"A complex, controversial topic, positively presented."
--School Library Journal

"Clear focus, careful explanations with occasional repetition of denser information, and a wealth of color photographs make this title inviting and accessible. . . and the kissin'-cute goats should entice quite a few readers to explore this project further."
--Bulletin of the Center for Children's Books
