Investigating the role of 'random walks' in particle diffusion

Several recent experiments identify unusual patterns in particle diffusion, hinting at some underlying complexity in the process which physicists have yet to discover. Through new analysis published in The European Physical ...

Printing atom by atom: Lab explores nanoscale 3D printing

It takes chemist Liaisan Khasanova less than a minute to turn an ordinary silica glass tube into a printing nozzle for a very special 3D printer. The chemist inserts the capillary tube—which is just one millimeter thick—into ...

Goldfish found to have travel distance memory

A team of researchers at the University of Oxford has found via experimentation that goldfish use markings on the floor below them to measure how far they have traveled. The findings are published in Proceedings of the Royal ...

Bacteria prompt a new look at the dynamics of collective behavior

A study led by Princeton researchers has revealed how bacteria navigate obstacles to ensure cohesive group movement. The finding has implications for understanding the general processes of collective migration, from cancer ...
