How spiders fix their webs

Spider silk is light and delicate, while incredibly resilient and tear-resistant. Understanding the structure and way of construction of these threads is a challenge taken up by a research team of Kiel University. The scientists examined five different spider species regarding the adhesion and tensile strength of a particular silk they use to fix the main thread to a surface. As shown in their new study published in the international Journal of the Royal Society Interface, the scientists found out that the substrate has a particularly significant impact on the silk’s adhesion.
