Around a decade ago, the discovery of Fickian yet non-Gaussian Diffusion (FnGD) in soft and biological materials broke up the celebrated Einstein's picture of Brownian motion. To date, such an ...

Cells are neither flat nor smooth, which has serious implications for prevailing plasma membrane models and cellular processes like cell signalling, adhesion and molecular clustering. Using ...

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 ...

In the classic fairy tale, "The Emperor's New Clothes," Hans Christian Andersen uses the eyes of a child to challenge conventional wisdom and help others to see more clearly. In similar fashion, ...

Table 1 Density, index of refraction and dielectric constants for the PMMA particles and three solvent mixtures composed of 50:50. 60:40 and 70:30 (by volume) ratios of decalin and TCE. In this work, ...

Researchers have discovered that common chemical reactions accelerate Brownian diffusion by sending long-range ripples into the surrounding solvent. Steve Granick, Director of the IBS Center for Soft ...

First observed by botanist Robert Brown in 1827, Brownian Motion describes the continuous, chaotic movement of tiny particles, such as pollen grains, suspended in a medium. This motion results from ...

When astronomers study the rotation of distant galaxies, they immediately come up against a puzzle. The stars are held together by gravity, which prevents them being slung into intergalactic space as ...
