Everything has a unique spectral signature. Imagine that you could detect the chemical makeup of a car, pipeline, or field of crops from space. In theory, that would allow scientists to identify leaks ...

Near infrared (NIR) hyperspectral imaging is a highly promising detection technology capable of capturing detailed 3D spectral-spatial information, facilitating the identification and characterization ...

Remote-sensing technology allows engineers and scientists to map land, forests, water bodies, and minerals without physically ...

The spectrum of reflected solar radiation emerging at the top of the atmosphere is rich with Earth system information. To identify spectral signatures in the reflected solar radiation and directly ...

Free-range eggs cost considerably more than those laid by caged hens, so it's not surprising that unscrupulous vendors would try to pass the latter off as the former. That's why Spanish scientists ...

A research team demonstrates that hyperspectral sensing, combined with advanced artificial intelligence, can accurately estimate multiple biochemical and mineral traits in grapevine leaves at once.

Global demand for critical minerals is accelerating, with the International Energy Agency (IEA) projecting a sixfold increase ...

Why do plants reflect in the green and have a “red edge” in the red, and should extrasolar photosynthesis be the same? We provide (1) a brief review of how photosynthesis works, (2) an overview of the ...

Accurate identification of liquors is important to distinguish between genuine and counterfeit brands, to check if particular samples have been diluted and to monitor batch variability. A team from ...

Each atom and molecule emits a unique spectral fingerprint, characterized by specific wavelengths of light extending across the electromagnetic spectrum, enabling their identification. These distinct ...
