Quantum entanglement, also called spooky action at a distance, is just one of the topics explored at the 2013 World Science Festival. Here, An artistic representation of two entangled mechanical ...

Today, light microscopy is a core technique in many areas of science and technology. In this article, we explore the basic working principle of light microscopy and discuss some more advanced forms of ...

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 ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The new microscope uses a 405 nm laser—the same wavelength ...

The techniques used in optical microscopy are important to ensure that a sample can be viewed as clearly as possible. This will provide information about its microscopic appearance. An optical ...

Microscopy has advanced significantly over the centuries, but modern tools still face trade-offs. Quantitative phase ...

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 ...

Quantum-physical fundamentals can be studied particularly well by the interactions between electrons and photons. Excited with laser light, for example, the energy, mass or velocity of the electrons ...

Scientists have been trying to figure out how it is possible for bacteria to perceive light and react to it ever since they started using microscopes 300 years ago. Scientists have now solved this ...

The first microscope that uses the eerie trick of quantum entanglement to increase its sensitivity has been developed by Japanese researchers. The new tool relies on a weird principle of quantum ...
