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. mark for My Articles 26 similar articles

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? mark for My Articles 80 similar articles
