Does an exciting but controversial new model of quantum gravity reproduce Einstein’s theory of general relativity? Scientists at Texas A&M University in the US explore this question in a paper ...

The point spread function (PSF) of a microscope describes the image of a point emitter. Knowing the accurate PSF model is essential for various imaging tasks, including single-molecule localization, ...

An in-line holographic microscope is an optical microscope outfitted with a coherent light source, such as a laser. Light scattered by the specimen interferes with the transmitted beam, and the ...

A completely new type of microscope can take 3D images of cells -- while working in a natural environment. The new technology is significantly faster and better than before and will give researchers ...

A team led by Raju Tomer, professor of biological sciences at Columbia University, has created a new design for microscopes ...

Researchers from Madrid explain a phenomenon that allows the direction of light emission to be controlled at the atomic scale. The paper provides a detailed explanation of how the profile of the light ...

Motor oil contains chemical additives that extend how long engines can run without failure, but, despite decades of ubiquity, how such additives actually work to prevent this damage have remained a ...

CORNING, NY — To closely inspect the evolution of the microscope, the Corning Museum of Glass is highlighting the lens-making behind the optical tool. Revealing the Invisible includes one of the few ...
