Artificial spider webs

Researchers report that when silk used by orb spiders to capture prey is compressed, the web filaments shorten by spooling inside tiny droplets of glue suspended on the threads, allowing the web to remain under tension, and that the process is reversed to extend the web; the authors used the findings to create hybrid fibers that compress like a liquid and extend like a solid. - Read at PNAS.org
