Synthetic skin reveals hidden 'Mona Lisa' when exposed to heat

Technology Engineering Synthetic skin reveals hidden'Mona Lisa' when exposed to heat The octopus-inspired material could lead to better camouflage technology for the military and beyond. Breakthroughs, discoveries, and DIY tips sent six days a week. Octopuses and their cephalopod cousins have long fascinated biologists with their seemingly supernatural shapeshifting. The cephalopods rapidly change color and texture, blending into their surroundings and evading predators. This natural camouflage is a remarkable bit of biology that engineers have tried to replicate, albeit with limited success.
