Researchers Explain Spider Web Stickiness
Todd Blackledge, Department of Biology (far left in photo), and a team of UA researchers have recently unraveled the mysteries behind the glue spiders use to spin their webs.
This path breaking illustration of knowledge production will have a powerful impact on the development of future bio-adhesives, result in multiple commercial applications, and marks another achievement in a field where UA is taking a leadership role in collaboration with regional partners and the medical community.
The research, “Viscoelastic Solids Explain Spider Web Stickiness,” will appear in Nature Communications (May, 2010). Learn More
