"Scientists have unpicked how the skin of the Texas horned lizard funnels water towards its mouth - and copied the principles in a plastic version. This reptile can collect water from anywhere, including the sand it walks on; the fluid then travels to its mouth through channels between its scales. A German-Austrian team quantified the skin's key features, notably the way its grooves narrow towards the snout. The bio-inspired plastic copy could have some engineering applications. Writing in the Journal of the Royal Society Interface, the researchers suggest that the "passive, directional liquid transport" they have described might find a home in distilleries, heat exchangers, or small medical devices where condensation is a problem."
