Scientists have developed instruments capable of measuring forces so small they are almost impossible to imagine. In ...

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, ...

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 ...

There are many situations in which it's important to know how much force one object is applying to another item. A small, thin sticker has been designed to measure and relay such data, without ...

Laser power measurement and force metrology are interlinked disciplines dedicated to quantifying the interaction between light and matter. In contemporary research, these fields have evolved from ...

The shaping of human embryos begins 4 days after fertilization with a process called compaction, during which the 8 to 16 cells of the embryo come into close contact to form a tighter structure. Four ...
