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 ...

Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes. Using a "spooky" phenomenon of quantum physics, Caltech researchers ...

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 ...

Most conventional light microscopes have a resolution of 200 nanometers – this means that imaged objects which are any closer together won't be seen as separate items. A new high-tech microscope slide ...

Powerful microscopes have made a quantum leap. Using a quantum trick with light has allowed researchers to examine living cells in unprecedented detail without destroying them, a technique that could ...

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 ...
