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 ...

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 ...

In 2011, while waiting for his new lab to be built at Stanford University, bioengineer Manu Prakash traveled to labs around the world, including in his home country of India. When he came across ...

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 ...
