Nature-inspired antibacterial metals

From aviation to medicine, various sectors are increasingly using materials that mimic the lotus plant, whose leaves have self-cleaning properties. Thanks to the bumpy surface structure covered with tube-shaped wax crystals, ...

New theory describes ice's slippery behavior

Winter is coming, promising the usual bouts of frozen precipitation for northern locations. The slickness of snow and ice is a big pain if you're driving, flying or walking, but can be a lot of fun if you strap on a pair ...

How stick insects honed friction to grip without sticking

When they're not hanging upside down, stick insects don't need to stick. In fact, when moving upright, sticking would be a hindrance: so much extra effort required to 'unstick' again with every step.
