Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission ...

A group of scientists from Nagoya University in Japan used a novel combination of technologies to investigate the principles of light–matter interaction in nanomaterials at the lowest and fastest ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Engineers have developed a technology that turns a conventional light microscope into what's called a super-resolution microscope. It improves the microscope's resolution (from 200 nm to 40 nm) so ...

In new studies published in Physical Review Letters and a special issue of Classical and Quantum Gravity on September 14, a team of researchers present the most precise test yet of the Weak ...
