    At the University Sapienza in Rome, a team of researchers from the Physics Department and the Institute for Nanotechnology of the CNR, lead by physics professor Roberto Di Leonardo, has shown that genetically modified bacteria, expressing the protein proteorhodhopsin, can be used as tiny propellers in micromachines that are invisible to the human eye and whose speed can be reliably and continuously tuned by shining green light of controlled intensity.
