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' ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...

Nature Communications acknowledges that when assessing application-oriented manuscripts, the level of novelty will likely be below that typically observed in more fundamental work. Instead, the ...
