Change in Publication Frequency in 2015
Starting in January 2015, Chaos will publish 12 monthly online issues, which will be collated into 4 quarterly print issues (January–March, April-June, July-September, and October-December). The quarterly print issue will contain all papers published online in that quarter. This change will facilitate expanded discoverability of the contents via monthly Table of Contents and indexing in the Web of Science and other indexing archival services in a timely manner.
Chaos is committed to publish selective and high quality content that is accessible to researchers from a broad spectrum of disciplines. Topics cover nonlinear dynamical systems, neural networks and neurodynamics, climate and earth sciences, condensed matter, fluid dynamics, synchronization, turbulence, solitons and coherent structures, time-series analysis, and more.
2014 Fields Medals:
- Martin Hairer is awarded a Fields Medal for his outstanding contributions to the theory of stochastic partial differential equations, and in particular for the creation of a theory of regularity structures for such equations.
- Maryam Mirzakhani is awarded the Fields Medal for her outstanding contributions to the dynamics and geometry of Riemann surfaces and their moduli spaces.
- Artur Avila is awarded a Fields Medal for his profound contributions to dynamical systems theory, which have changed the face of the field, using the powerful idea of renormalization as a unifying principle.
- Manjul Bhargava is awarded a Fields Medal for developing powerful new methods in the geometry of numbers, which he applied to count rings of small rank and to bound the average rank of elliptic curves.

You're not imagining it -- traffic within cities really is more chaotic, according to a new mathematical analysis by a team of researchers in Colombia and Chile. WASHINGTON, DC, July 21, 2015 – It's not unusual for two drivers to depart from the same location, head out to the same destination, drive more or less the same speed and nevertheless arrive at dramatically different times, with one driver taking significantly longer to arrive.

Analyzing Lagrangian coherent structures in water around swimming fish reveals how they move and may help in the study of airplane flight dynamics and other complex fluid flows. WASHINGTON, D.C., June 23, 2015 -- Fish may seem to glide effortlessly through the water, but the tiny ripples they leave behind as they wriggle their way along are evidence of a constant give-and-take of energy between the swimmer and its aqueous environment -- a momentum exchange that propels the fish forward but is devilishly tricky to quantify because of the continuous nature of a large, ever-flowing body of water.

Devastating flooding, such as Iowa's flood of 2008, motivated a team of researchers to analyze a hydrologic model with the potential to predict the extent of flooding based on predicted rain patterns. WASHINGTON, D.C., March 10, 2015 -- Devastating floodwaters such as those experienced during Iowa's Flood of 2008 -- which swamped many Iowa communities, along with ten square miles of Cedar Rapids -- are notoriously difficult to predict.

WASHINGTON D.C., September 2, 2014 -- The Great Pacific Garbage Patch is an area of environmental concern between Hawaii and California where the ocean surface is marred by scattered pieces of plastic, which outweigh plankton in that part of the ocean and pose risks to fish, turtles and birds that eat the trash. Scientists believe the garbage patch is but one of at least five, each located in the center of large, circular ocean currents called gyres that suck in and trap floating debris.

Right-sizing the grid could reduce blackout risk, according to new analysis in the journal 'Chaos'. Some 90 years ago, British polymath J.B.S. Haldane proposed that for every animal there is an optimal size -- one which allows it to make best use of its environment and the physical laws that govern its activities, whether hiding, hunting, hoofing or hibernating. Today, three researchers are asking whether there is a "right" size another type of huge beast: the U.S. power grid.
