PLOS ONE Science versus the 'Horatio Alger myth'
In a new study published today in the journal PLOS ONE, Los Alamos National Laboratory scientists have taken a condensed matter physics concept usually applied to the way substances such as ice freeze, called 'frustration,' and applied it to a simple social network model of frustrated components. They show that inequality of wealth can emerge spontaneously and more equality can be gained by pure initiative.

Scientific Reports Origin of spooky meteor noises reappraised by Sandia researchers
Sound travels more slowly than light. Then why does the sound of a meteor entering Earth's atmosphere appear simultaneously, or even prior, to the sight of the meteor itself? Sandia scientists believe they have the answer.
Public Release: 13-Feb-2017 Next-gen dark matter detector in a race to finish line
The race is on to build the most sensitive US-based experiment designed to directly detect dark matter particles. Department of Energy officials have formally approved a key construction milestone that will propel the project toward its April 2020 goal for completion.

npj Computational Materials Machine learning method accurately predicts metallic defects
For the first time, Berkeley Lab researchers have built and trained machine learning algorithms to predict defect behavior in certain intermetallic compounds with high accuracy. This method will accelerate research of new advanced alloys and lightweight new materials for applications spanning automotive to aerospace and much more.

Nature Supercomputing, experiment combine for first look at magnetism of real nanoparticle
A multi-institution team simulated, for the first time, atomic-level magnetic properties in regions of a real nanoparticle based on experimental data. UCLA and Berkeley Lab's cutting-edge imaging and 3-D reconstruction techniques combined with the 27-petaflop Titan supercomputer at OLCF and the award-winning LSMS magnetic structure code, developed at ORNL, enabled researchers to model the magnetic properties of over a thousand atoms of an iron-platinum nanoparticle -- a material that has applications for next-generation magnetic storage devices.

Public Release: 1-Feb-2017 The shape of melting in two dimensions
As part of her team's research into matter's tendency to self-organize, Sharon Glotzer of the University of Michigan ran a series of hard particle simulations to study melting in two-dimensional (2-D) systems. Specifically, the team explored how particle shape affects the physics of a 2-D solid-to-fluid melting transition.
