Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

Silky smooth: Researchers unravel mysteries about spiders

Scientists have found recent success on the path to understanding what makes the fiber that spiders spin -- weight for weight -- at least five times as strong as steel. Spider silk is an exceptional biological polymer related to collagen (the stuff of skin and bones), but much more complex in its structure. A team of chemists is studying its molecular structure in an effort to produce materials for uses ranging from civil and mechanical engineering to artificial, yet biocompatible, tendons.
