Light Used To Measure The big Stretch In Spider Silk Proteins

While working to improve a tool that measures the pushes and pulls sensed by proteins in living cells, biophysicists say they've discovered one reason spiders' silk is so elastic: Pieces of the silk's protein threads act like supersprings, stretching to five times their initial length. The investigators say the tool will shed light on many biological events, including the shifting forces between cells during cancer metastasis.

Proteins Silk Spider
Strange silk: Why rappelling spiders don't spin out of control. Researchers show that unlike human hair, metal wires or synthetic fibers, spider silk partially yields when twisted. This property quickly dissipates the energy that would otherwise send an excited spider spinning on the end of its silk. A greater understanding of how spider silk resists spinning could lead to biomimetic fibers that mimic these properties for potential uses in violin strings, helicopter rescue ladders and parachute cords.
