From Wyoming mountains to Connecticut forests, tracking feline apex predators

If GPS data from someone's phone tells you they are in a grocery store at 10 a.m. on a Saturday, you can assume they are shopping for their weekly meals.

In search of universal laws of diffusion with resetting

The manner in which animals penetrate a neighborhood searching for food shows similarities to the movements of liquid particles in plant capillaries or gas molecules near an absorbing wall. These phenomena—and many others ...

Tiny motors take a big step forward

Motors are everywhere in our day-to-day lives—from cars to washing machines. A futuristic scientific field is working on tiny motors that could power a network of nanomachines and replace some of the power sources we use ...

Âé¶¹ÒùÔºicist defends validity of Stokes-Einstein equation in living systems

A physicist at the University of Arkansas has defended the validity of the Stokes-Einstein equation, one of Albert Einstein's most famous equations, as it relates to biology. The research will help scientists better understand ...

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 ...
