Quantitative phase images reveal more details than classical microscopy images. The KAUST technique captures both bright-field images (top) and phase images (bottom) in a single measurement. Credit: KAUST Microscopes have been at the center of many of the most important advances in biology for many centuries. Now, KAUST researchers have shown how a standard microscope

Micrograph of NIST’s high-resolution camera made of 1,024 sensors that count single photons, or particles of light. The camera was designed for future space-based telescopes searching for chemical signs of life on other planets. The 32-by-32 sensor array is surrounded by pink and gold wires connecting to electronics that compile the data. Credit: V. Verma/NIST

Intensity distribution of an electric wave field that applies a well-defined torque onto the quadratic target. Credit: TU Wien Atoms, molecules or even living cells can be manipulated with light beams. At TU Wien a method was developed to revolutionize such “optical tweezers”. They are reminiscent of the “tractor beam” in Star Trek: Special light

PPPL physicist Fatima Ebrahimi. Credit: Elle Starkman / PPPL Office of Communications An obstacle to generating fusion reactions inside facilities called tokamaks is that producing the current in plasma that helps create confining magnetic fields happens in pulses. Such pulses, generated by an electromagnet that runs down the center of the tokamak, would make the

Van-der-Waals layered CuInP2S6 has different properties depending on the locations of copper atoms (orange spheres). Unified theory and experiment led to the discovery of two co-existing phases which are connected through a quadruple energy well whose properties can be harnessed to provide materials with new functions.

A set up for ultrafast spectroscopy, as used in the study. Credit: Maxim Pchenitchnikov, University of Groningen More Semiconductors convert energy from photons (light) into an electron current. However, some photons carry too much energy for the material to absorb. These photons produce “hot electrons,” and the excess energy of these electrons is converted into

Credit: Heriot-Watt University More Researchers at Heriot-Watt University, in collaboration with researchers from the University of Toulouse, France, have proposed a novel framework that combines statistical models with highly scalable computational tools from the computer graphics community to accurately extract the 3-D information in real-time (50 frames per second). The novel method allows for target
