International team of physicists explore microscopic filament behavior

Recently-published research from an international team of physicists reveals how the three-dimensional shape of rigid microscopic filaments determines their dynamics when suspended in water, and how control of that shape ...

Defying gravity with the Brazil nut effect

Âé¶¹ÒùÔºicists from the University of Utrecht and the Faculty of Âé¶¹ÒùÔºics at the University of Warsaw have observed—for the first time experimentally—the Brazil nut effect in a mixture of charged colloidal particles.

Melting glasses: The glass-to-liquid transition

The process of liquid-to-glass transition is a complex procedure in science, as is the glass-to-liquid transition known as glass melting. In a new report published in Science Advances, Qi Zhang and a research team in physics ...

Breaking down the Nernst–Einstein relation, carbon nanotube style

When it comes to studying particles in motion, experimentalists have followed a 100-year-old theory that claims the microscopic motion of a particle is determined by random collisions with molecules of the surrounding medium, ...

A surprising way to trap a microparticle

When physicists recently steered a tiny microparticle toward a cylindrical obstacle, they expected one of two outcomes to occur. The particle would either collide into the obstacle or sail around it. The particle, however, ...

Stick to your lane: Hidden order in chaotic crowds

Have you ever wondered how pedestrians 'know' to fall into lanes when they are moving through a crowd, without the matter being discussed or even given conscious thought?

Thermal fluctuations and oscillation modes found to determine the uptake of bacteria in cells

How and with what effort does a bacterium—or a virus—enter a cell and cause an infection? Researchers from Freiburg have now made an important contribution to answering this question.

Statistical physics theorem also valid in the quantum world, study finds

Âé¶¹ÒùÔºicists at the University of Bonn have experimentally proven that an important theorem of statistical physics applies to so-called "Bose-Einstein condensates." Their results now make it possible to measure certain properties ...

Laser-controlled synthetic microswimmers show swarm intelligence can be caused by physical mechanisms

Seemingly spontaneously coordinated swarm behavior exhibited by large groups of animals is a fascinating and striking collective phenomenon. Experiments conducted by researchers at Leipzig University on laser-controlled synthetic ...

Ribosomes search AUG codons in bidirectional scanning, challenging the first-AUG rule

Translation, a process that expresses the genetic information from messenger RNA (mRNA) to protein, is vital to maintain cellular protein homeostasis. To synthesize functional proteins and avoid toxic translation products, ...
