A non-destructive method of analysing molecules in cells

When investigating how tumors grow, or how pharmaceuticals affect different types of cells, researchers have to understand how molecules within a cell react—and interact. This is possible with modern laser microscopy. Until ...

Avalanche photodiode breaks performance record for LiDAR receivers

Electrical and computer engineers at the University of Virginia and University of Texas-Austin have developed an avalanche photodiode that achieved record performance and has the potential to transform next generation night-vision ...

Performing optical logic operations by a diffractive neural network

Optical logical operations have sparked major interest in the past decade since they can enable many applications, particularly those involving high-throughput and on-the-fly data processing such as secured wireless communication ...

Saturable plasmonic metasurfaces for laser mode locking

Plasmonic metasurfaces are artificial 2-D sheets of plasmonic unit cells repeated in a subwavelength array, which give rise to unexpected wave properties that do not exist in nature. In the linear regime, their applications ...

Controlling superconductors with light

A researcher at the Center for Theoretical Physics of Complex Systems within the Institute for Basic Science (IBS, South Korea), Professor Ivan Savenko, has reported a conceptually new method to study the properties of superconductors ...

Researchers achieve broadest microcomb spectral span on record

Xu Yi, assistant professor of electrical and computer engineering at the University of Virginia, collaborated with Yun-Feng Xiao's group from Peking University and researchers at Caltech to achieve the broadest recorded spectral ...

Scientists boost microwave signal stability a hundredfold

Researchers at the National Institute of Standards and Technology (NIST) have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the stability of microwave ...

New mobile health tool measures hemoglobin without drawing blood

Researchers have developed a way to use smartphone images of a person's eyelids to assess blood hemoglobin levels. The ability to perform one of the most common clinical lab tests without a blood draw could help reduce the ...
