A team of scientists has demonstrated how the natural movement of bacteria could be harnessed to assemble and power microscopic ‘windfarms’ – or other man-made micro-machines such as smartphone components.
Using computer simulations, the scientists from Oxford University demonstrated that the chaotic swarming
