Laser guided maglev graphite air hockey A graphite disk levitating over a bed of rare earth permanent magnets can be 'pushed' around or made to spin using a laser beam, Japanese scientists have shown. The phenomenon can also be used to convert sunlight into movement, offering a possible alternative way to harness solar energy. |

Shine on you crazy Diamond The UK's Diamond Light Source is celebrating five years since it opened its doors to scientists. The joint venture between the Science and Technology Facilities Council and the Wellcome Trust established Diamond as the successor to the UK's previous synchrotron source at Daresbury. |

Make or break: the laws of motion The machine metaphors of nanochemistry and molecular biology now make it plain that dynamic function arises from the use of weak, temporary interactions. The question biology has to face is: what is the optimal bond strength for a given mechanical function? |
