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 ...

Researchers at the University of Illinois at Urbana-Champaign have shown for the first time that expensive aberration-corrected microscopes are no longer required to achieve record-breaking ...

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 ...

Anyone who has ever used a microscope knows that it takes time to bring a sample into sharp focus. Each time you move the slide, the image blurs, and you have to stop and carefully turn a knob to ...

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 ...
