Glass transition meets Fickian-non-Gaussian Diffusion

Glass transition is a Grand Challenge in condensed matter physics and still reveals surprises, despite decades of intense research. For instance, diffusion in glassy liquids was until now thought to be qualitatively similar ...

Experimental evidence for long-distance electrodynamic intermolecular forces

While classical and quantum electrodynamics present the existence of dipole-dipole long-range electrodynamics forces, they remain to be experimentally observed. The discovery of completely new and unanticipated forces that ...

Researchers find the best way for bacteria to navigate maze-like environments

When bacteria spread through soil, tissues and other environments crammed with obstacles, keeping on the straight and narrow path leads to dead ends. Instead, bacteria move through open spaces until they get trapped, then ...

Throwing down the scientific gauntlet to assess methods for anomalous diffusion

Almost 80 years after Scottish botanist Robert Brown described the continuous random motion of microscopic particles in a fluid, Albert Einstein provided a theoretical foundation for this observation. Since then, scientists ...

The Riemann conjecture unveiled by physics

A mystery of mathematics that has remained unsolved for more than 150 years can be unraveled thanks to a completely unexpected approach coming from statistical physics. This is the important conclusion of Giuseppe Mussardo, ...

Study reveals the complex behaviour of sea urchins regarding the predators' threat

Sea urchins, albeit having a limited and ancestral sensory system, can show a complex behavior when escaping a predator. These marine invertebrates tend to move slowly and with unpredictable movements, but when they smell ...

New sensor detects ever smaller nanoparticles

Conventional microscopes produce enlarged images of small structures or objects with the help of light. Nanoparticles, however, are so small that they hardly absorb or scatter light and, hence, remain invisible. Optical resonators ...

Physics Nobel rewards work on complex systems, like climate

Three scientists won the Nobel Prize in physics Tuesday for work that found order in seeming disorder, helping to explain and predict complex forces of nature, including expanding our understanding of climate change.

Fast nanoparticle diffusion in synovial fluid and hyaluronic acid solutions

Nanoparticles have applications as therapeutic agents for joint diseases such as osteoarthritis. But the role of nanoparticle diffusion in synovial fluid or the fluid inside the joint is incompletely understood. In a new ...
