Interactions & forces, as a research area, focuses on the quantitative description and theoretical understanding of how physical entities influence one another via fundamental interactions and emergent effective forces. It encompasses studies of gravitational, electromagnetic, strong, and weak interactions, along with interatomic, intermolecular, and many-body forces in condensed matter, soft matter, and plasma systems. Research typically integrates field theories, potential models, and numerical simulations to characterize force laws, energy landscapes, and response functions across scales, from subatomic particles to macroscopic structures, enabling predictive models of structure, dynamics, and phase behavior in diverse physical and engineered systems.
Inside cells, certain functions are carried out by locally adjusting molecular composition. This condensation of material results in the formation of dense droplets that can dynamically rearrange. Because of this, interactions ...

Water molecules do not simply swirl around in complete disorder; they can form certain preferred structures. This scientific fact is often presented in entirely unscientific ways. For example, when people speak of an alleged ...

The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it back using nothing more than a single, compact chip is a challenge we set out to address in our new ...
Researchers have developed a sensor about the size of a grain of rice that can measure forces and twisting motions in all directions using light instead of traditional electronics. The new sensor could help robotic tools ...

In tissue engineering, the tiniest bit of improper force can harm a living culture. Spheroids—3D clumps of cells—can be used to model complex human tissues, because they can re-create specific cell-to-cell and cell-to-matrix ...

Light does more than illuminate the world—it can also push and twist matter. It was back in the 1870s that James Clerk Maxwell first predicted that light carries momentum and can exert pressure on objects. Nearly a century ...
