Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard ...

A team presents a groundbreaking advance for the world of high-resolution fluorescence microscopy: The innovative method enables researchers for the first time to use biomolecules as molecular rulers ...

A Golomb ruler is very different from your run-of-the-mill tape measure. These strange rulers are defined in terms of constraints, and are “optimized” when they are the shortest they can be. While not ...
