You may have missed… beetles use their butts to stay hydrated, smart sensing bandage, new bushfire safe rooms, and a robot caterpillar

Your hit of the best of last week’s science.

Researchers at North Carolina State University have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot’s movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.
