As brain tumors grow, they must do one of two things: push against the brain or use finger-like extensions to invade and destroy surrounding tissue. Previous research found tumors that push - or put ...

Researchers have developed a scalpel with built-in force-measuring sensors and coupled it with a machine-learning model that could streamline how doctors are trained to perform surgery and pave the ...

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 ...
