Scientists have uncovered the genetic sequence for one of the strongest silks that spiders produce, a discovery that could one day be used to make super spider-silk products for humans. Not all spider silk are created equal. For example, spiders use dragline silk to create the scaffolding for their webs, but another type of silk, known as capture silk, is used to fill out the web. While dragline silk is strong, capture silk is more elastic and also sticky, making it better suited for trapping insects that stray too close. In total, spiders produce approximately seven different types of silk,...
