Researchers simulate behavior of 'active matter'

Microspheres in a fluid, spinning in opposite directions, create flow patterns that affect other particles. Computer simulations show the particles self-assembling into different structures at different concentrations: bands, ...

Understanding the dynamics of crowd behavior

Crowds formed from tiny particles disperse as their environment becomes more disordered, according to scientists from UCL, Bilkent University and Université Pierre et Marie Curie.

First opal-like crystals discovered in meteorite

Scientists have found opal-like crystals in the Tagish Lake meteorite, which fell to Earth in Canada in 2000. This is the first extraterrestrial discovery of these unusual crystals, which may have formed in the primordial ...

Scientists offer designer 'big atoms' on demand

In the not-so-distant future, researchers may be able to build atoms to your specifications with the click of a button. It's still the stuff of science fiction, but a team at the University of Colorado Boulder reports that ...

Shape-encoded dynamic assembly of mobile micromachines

Field-directed and self-propelled colloidal assembly can be used to build micromachines to perform complex motions and functions, although their integration as heterogenous components with specified structures, dynamics and ...
