Âé¶¹ÒùÔºicists observe individual atomic collisions during diffusion for the first time

In the world of research, diffusion is understood as a process in which tiny particles disperse uniformly throughout a gas or liquid. Although these media are made up of individual particles, diffusion is perceived as a continuous ...

The sharpest laser in the world: Âé¶¹ÒùÔºicists develop a laser with a linewidth of only 10 mHz

No one had ever come so close to the ideal laser before: theoretically, laser light has only one single color (also frequency or wavelength). In reality, however, there is always a certain linewidth. With a linewidth of only ...

The hidden order in DNA diffusion

A different approach to analyzing the motion of diffusing molecules has helped overturn the long-held assumption that DNA molecules move in a haphazard way. KAUST researchers reveal for the first time that DNA molecules move ...

Properties of subatomic 'soup' that mimics the early universe

By teasing out signatures of particles that decay just tenths of a millimeter from the center of a trillion-degree fireball that mimics the early universe, nuclear physicists smashing atoms at the Relativistic Heavy Ion Collider ...

Light-controlled gearbox for nanomachines

Rewarded with a Nobel Prize in Chemistry in 2016, nanomachines provide mechanical work on the smallest of scales. Yet at such small dimensions, molecular motors can complete this work in only one direction. Researchers from ...

Mystery of the dark solitons

When your heart beats, blood courses through your arteries in waves of pressure. These pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. Scientists call such ...

Destabilized solitons perform a disappearing act

When your heart beats, blood courses through your veins in waves of pressure. These pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. Scientists call such robust ...

Research pushes concept of entropy out of kilter

Entropy, the measure of disorder in a physical system, is something that physicists understand well when systems are at equilibrium, meaning there's no external force throwing things out of kilter. But new research by Brown ...
