Biologists have shown that measuring quantities of fish DNA in seawater can reveal how many fish inhabit that environment. This discovery could enable quicker and more effective surveys of fish ...

Researchers have created a chip on which laser light interacts with a tiny cloud of atoms to serve as a miniature toolkit for measuring important quantities such as length with quantum precision. The ...

NIST's prototype chip for measuring important quantities such as length with quantum precision. The device works by using a laser to probe atoms to generate infrared light at a precise wavelength. The ...
