Atmospheric gravity waves drive winds, temperature and chemical composition in the middle and upper atmosphere, but not enough is known about those that occur at higher altitudes. Now though, an ...

This prototype millimeter-wave radar sensor developed at UC Davis is capable of measuring extremely small vibrations and movements while being energy-efficient and cheap to produce. (Omeed Momeni/UC ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of Global ...

In the quirky quantum world, particles can be affected by forces that they never directly encounter. A classic example is the ...

(Nanowerk News) Researchers at Eindhoven University of Technology (TU/e) have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are ...

Researchers develop a proof-of-concept millimeter wave radar sensor that can detect extremely small vibrations and movements. Researchers at the University of California, Davis, have developed a proof ...

Global Navigation Satellite System (GNSS) receivers help with precise location tracking and can detect disturbances in the upper atmosphere (ionosphere) by measuring delays and changes in ...
