The U.S. Air Force is testing layered counter-drone defenses through dedicated experimental facilities, moving away from the ...

Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals with high sensitivity and spatial resolution is needed for a wide range of ...

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' ...
