Here Red particles represent Active agents and green represent  Passive  agents. The variation in density of the mixture and the strength of the self-motile agents creates vortexes in the fluid space.

For generations, researchers have thought about ecology in terms of the landscape. Now, new technology and methods are allowing scientists to record and examine the particular "soundscape" of a place.

Testing the stability of cylindrical tube made from 15,360 hexagonally packed magnetic balls (192 rings, each made up of 80 balls). A high-speed camera recording reveals crumpling at the base of the cylindrical tube, reminiscent of paper-like crumpling, when it loses stability from shaking.

The polymer material is stretched with an increasing force resulting in a corresponding brighter emission of light from the mechanophore (here under UV light and with false colors). The graph shows the intensity of the emitted light following punctual increases in the stretching force applied to the polymer.  

PhD Student Han Yan in the Theory of Quantum Matter Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) put a fracton model in a curved space – where holography works for gravity. Yan checked if the properties also work for fracton models, and they did.
