Researchers developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute ...

Spectrum analyzers are crucial in electronic warfare and signals intelligence, enabling detection, interception, and analysis of enemy signals to protect friendly communications and disrupt ...

The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.

Researchers developed a tiny laser comb that detects chemicals extremely accurately, using ultrabroadband technology for ...

A new discovery of high-frequency-retrograde vorticity waves in the Sun defy all explanations. The discovery indicates that vortices on the surface of the Sun move at three times the speed as ...

Scientists use devices known as frequency comb lasers to search for methane in the air above oil and gas operations and to screen for signs of infection in human breath. A new study could help make ...
