Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that ...

A new, noninvasive method for measuring brain blood flow with light has been developed by biomedical engineers and neurologists and used to detect brain activation. The new method, functional ...

Using infrared light and machine learning, researchers have developed a method to effectively screen human health and its deviations at a population level. Envision a scenario where a single drop of ...

Suitable monitoring and control of process temperatures require exceptional guidance by the producer or a basic understanding of the measurement techniques required on the part of the customer.

To investigate how melanin affects the accuracy of near-infrared spectroscopy (NIRS) measurements, researchers correlated the melanin levels of 35 adults with a diverse range of skin tones, measured ...

(Nanowerk News) For the first time, a team of Dutch, German and South Korean scientists have shown how light can squeeze through any hole regardless of its size using Terahertz (THz) radiation. Their ...
