The ability to work-out the Casimir force between arbitrarily-shaped objects could be one step closer thanks to work done by physicists in the US. The team used an atomic force microscope to measure ...

The attractive force between two surfaces in a vacuum - first predicted by Hendrik Casimir over 50 years ago - could affect everything from micromachines to unified theories of nature. What happens if ...

When two objects separated by a vacuum are barely a whisker apart, a strange attraction comes into play. Philip Ball meets the physicists who are trying to make something out of nothing. “Nothing can ...
