LONDON — Researchers at the University of Regensburg in Germany and IBM's Almaden Research Labs in California have calculated for the first time exactly how much effort is needed to drag a single atom ...

Researchers have developed tiny flexible lasers that can be used to measure forces inside living cells. The new lasers could ...

What started as a question to the A-exam became a revolutionary discovery in the material science field. Neil Y.C. Lin — a graduate student from Cornell University pursuing a physics Ph.D. — was asked ...

What is an Actuation Test? An actuation test measures the process that occurs when a mechanical device operates. For example, the release of a hairspray aerosol, a liquid soap hand pump, an inhaler ...

The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...

Researchers from Lawrence Berkeley National Laboratory and UC Berkeley published a paper last week on their measurement of the smallest force ever quantified. Researchers applied a known force to a ...

Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment ...
