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.
Researchers at the University of Twente have developed an optical method that follows the shape changes of a single protein in liquid without attaching anything to it. It reads the protein's structure from its own molecular ...

A small change in acidity can transform the world around us. A squeeze of lemon changes the taste of food. Vinegar preserves vegetables. Stomach acid helps break down a meal. These familiar effects come from protons—tiny ...
It's one thing to design a pharmaceutical drug. It's another to know if and why it actually works; not on paper or in a computer model, but inside the chaotic world of living systems, where proteins twist into shape, atoms ...

This April, when the spring breeze carried the formal acceptance notice of our paper by the Journal of the American Chemical Society to my desk, my thoughts instantly drifted back to the late Phil Geissler. A legendary physical ...
Birds in flocks, bacteria and cells: In many collective systems, individual elements respond to only part of their surroundings, seemingly defying Newton's third law of motion—action equals reaction. These exceptions are ...
