Harnessing machine learning to make nanosystems more energy efficient

Getting something for nothing doesn't work in physics. But it turns out that, by thinking like a strategic gamer, and with some help from a demon, improved energy efficiency for complex systems like data centers might be ...

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.
