Scientists have long been fascinated with the ability of certain octopus and squid species to adapt to their surroundings by changing the texture and color of their skin. This trait allows the creatures to effectively use a natural form of three-dimensional morphing to camouflage themselves against would be attackers.
In a study featured in the journal Science, graduate students at Cornell University in New York describe how they were able to use the concept of glowing octopus skin to develop an artificial version that can stretch several times its original size and even emit light.
