The law of hydrodynamics governing the way internally driven systems behave could explain their complex structure

Physicists use hydrodynamics to understand the physical mechanism responsible for changes in the long-range order of groups of particles. Particularly, Aparna Baskaran of Brandeis University, Massachusetts, USA, and Cristina Marchetti of Syracuse University, New York, USA, focused on ordered groups of elongated self-propelled particles. They studied the breakdown of long-range order due to fluctuations that render them unstable and give rise to complex structures, in a study about to be published in EPJ E.

Using the world's rarest element to study the world's rarest force

In September 2012 an experiment at the TRIUMPH accelerator complex reached a milestone. The FrPNC collaboration —-short hand for Francium Parity Non-conservation—-succeeded in trapping several kinds of francium, including the isotope Fr-207, which had never before been trapped. There is less than a gram of Fr at any given time in the whole earth. With a halflife of mere seconds, and existing only briefly at particle accelerators, francium is the rarest species in the periodic table of elements up to uranium.

Beautiful physics: Tying knots in light

New research published today seeks to push the discovery that light can be tied in knots to the next level.
