Superhero Silk
Hu Wenbo, assistant professor at China's Southwestern University, pins down a Joro spider to extract its silk, in this photo from our March 2026 cover story. Spider silk is five times stronger than steel by weight but completely organic. If mass-produced, it could unlock everything from improved bulletproof vests to ultra-light jet planes to next-generation vaccine delivery.
