Forces that are exerted by a living cell or a microorganism are tiny and often not larger than a few nanonewtons. For comparison, one nanonewton is the weight of one part in a billion of a typical ...

Until about 10 years ago, the force test and measurement industry had been fairly unimaginative. It had developed a standard way of building analog load cells, torque transducers and other devices, ...

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 ...

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 at the University of California San Diego and the Allen Institute of Cell Science have developed a new computational method that can measure the forces cells exert on each other by ...

Force spectroscopy relies on the precise measurement of forces acting on a probe as it interacts with a sample. The key principles of force spectroscopy include: AFM-based force spectroscopy is the ...

In a finding that could be useful in designing small aquatic robots, researchers have measured the forces that cause small objects to cluster together on the surface of a liquid -- a phenomenon known ...

Cellular competition is an essential surveillance mechanism that eliminates unwanted cells, playing a key role in development, infection response, and tumor formation. While the role of biochemical ...

In 1856, Lord Kelvin observed that metallic conductors subjected to mechanical strain exhibit a change in their electrical resistance. Since that time, engineers have attempted to measure and quantify ...

A new computational method can measure the forces cells exert on each other by analyzing time-lapse videos of cell colonies. It could enable researchers to gain fundamental insights into what role ...
