Before it took over her life, Leila Gharani mostly took Microsoft Excel for granted. She was working on a process optimization project for a large paper-products manufacturer—a job that, to hear her ...

Some of the most sensitive methods of measuring magnetic fields use interactions of resonant light with atomic vapour. Recent developments in this vibrant field have led to improvements in sensitivity ...

A new approach to sensing mechanical motion allows high-frequency measurements to be made with cantilevers that are smaller than the wavelength of light. The development of the atomic force microscope ...
