These penguins are wearing actual penguin suits, but they’re more about the substance than style. Penguins are facing planetary perils, and these special vests are designed to help.
In Chile, injured penguins are swimming, eating, and shimmying in them. The cocoon of red fabric is woven with healing minerals, copper, which helps prevent bacteria and fungi from growing, and zinc, which encourages new blood vessels to form. Together, they can repair damaged tissue more quickly.
IIRC Microban and related treatments work by coating the surface in nano sized spikes that puncture bacteria’s cell walls on contact. But the stuff is apparently not just one product, rather a range of products all lumped under that name with various compositions depending on what kind of surface they’re intended to be applied to. Sometimes the little nano-teefies do indeed contain silver.
NGL that’s actually really neat. It does not change my opinion of corporate metallurgic dickery, but it’s still neat
