When combined with iridescent colouration, a matt target surface appearance confers greater survival benefits in beetles than a glossy surface, scientists at the University of Bristol have found.
Throughout evolution, prey animals have adopted a range of strategies to evade their predators. But these oftentimes elaborate strategies come at a cost.
The high-contrast pattern of giant pandas helps them blend in with their natural environment.
Inspired by the color-changing skin of cuttlefish, octopuses and squids, Rutgers engineers have created a 3D-printed smart gel that changes shape when exposed to light, becomes “artificial muscle” and may lead to new military camouflage, soft robotics and flexible displays. The engineers also developed a 3D-printed stretchy material that can reveal colors when light changes, according to their study in the journal ACS Applied Materials & Interfaces.
In conjunction with Australia’s Department of Defence, University of South Australia material scientists have developed a range of lightweight panels that can change colour on demand, allowing drones to match their appearance to the background colours of the sky.
Glass frogs are well known for their see-through skin but, until now, the reason for this curious feature has received no experimental attention.
