Explore the difference between calculated forces and constraint forces in this physics-focused video! Learn how to identify, compute, and distinguish between the forces acting on objects, including ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature ...

Invented 30 years ago, the atomic force microscope has been a major driver of nanotechnology, ranging from atomic-scale imaging to its latest applications in manipulating individual molecules, ...

Resolution boost: localization AFM map (second from the left) of the AqpZ molecule. Also shown are a simple AFM image, the AgpZ structure derived from X-ray crystallography and a comparison of LAFM ...

The new simulations show a cross section of the star and its surrounding disk of gas. In the left image, where the young star is weakly magnetized, gas can be seen flowing freely from the surrounding ...

(A–C) Representative images reconstructed by conventional method (left) and new method (right) of microtubules, nuclear pore complexes and F-actin samples. The regions enclosed by the white boxes are ...

In order to increase our understanding of structural dynamics of biomolecules at the single-molecule level, they would need to be captured at the sub-nanometer scale and in physiologically relevant ...
