Scientists have created the world’s smallest chessboard – with pieces half the width of a human hair. The tiny board sits on top of a computer microchip. The chip powers a robotic arm that grips micro tweezers to pick up each piece and move them around the board. Students at Texas Tech University took nine months to design the board before entering it in a competition for tiny creations. The chessboard picked up first prize and the team were rewarded with having the design being made into reality.
