Beetles have an impressive ability to walk underwater. It is all down to tiny bubbles trapped between hair-like structures on their feet. [...] Inspired by the beetles, researchers developed a polymer structure covered in bristles that mimic the beetles' feet. Attached to small objects — such as the treads of a toy bulldozer — it successfully stuck them to vertical surfaces underwater.

"Researchers in the lab of Rice materials scientist Pulickel Ajayan found a way to mimic the Stenocara beetle, which survives in the desert by stretching its wings to capture and drink water molecules from the early morning fog. They modified carbon nanotube forests grown through a process created at Rice, giving the nanotubes a superhydrophobic (water-repelling) bottom and a hydrophilic (water loving) top. The forest attracts water molecules from the air and, because the sides are naturally hydrophobic, traps them inside."
