Nature Strange electrons break the crystal symmetry of high-temperature superconductors
Scientists have found surprising electron behavior that may help unravel the ever-elusive mechanism behind high-temperature superconductivity -- a phenomenon in which electrical current flows freely without resistance through a material at unusually high temperatures relative to those of conventional superconductors.

Weather and Climate Extremes 'Hindcasting' study investigates the extreme 2013 Colorado flood
Using a publicly available climate model, Berkeley Lab researchers 'hindcast' the conditions that led to the Sept. 9-16, 2013 flooding around Boulder, Colo. and found that climate change attributed to human activity made the storm much more severe than would otherwise have occurred.
Public Release: 20-Jul-2017 Berkeley Lab to lead multimillion-dollar geothermal energy project
The Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) will lead a new $9 million project aimed at removing technical barriers to commercialization of enhanced geothermal systems (EGS), a clean energy technology with the potential to power 100 million American homes.

Public Release: 18-Jul-2017 3-D models help scientists gauge flood impact
Using one of the world's most powerful supercomputers, a University of Iowa team performed one of the first highly resolved, 3-D, volume-of-fluid Reynolds-averaged Navier-Stokes (RANS) simulations of a dam break in a natural environment. The simulation allowed the team to map precise water levels for actual flood events over time.

Nature Climate Change Titan simulations show importance of close 2-way coupling between human and Earth systems
By using supercomputers such as the Oak Ridge Leadership Computing Facility's Titan, a large multidisciplinary team of scientists developed a new integrated climate model designed to reduce uncertainties in future climate predictions as it bridges Earth systems with energy and economic models and large-scale human impact data.
Public Release: 17-Jul-2017 Lighting up the study of low-density materials
Sandia National Laboratories studies myriads of low-density materials, from laminate layers in airplane wings to foams and epoxies that cushion parts. So Sandia borrowed and refined a technique being studied by the medical field, X-ray phase contrast imaging, to look inside the softer side of things without taking them apart.

Nature Communications Studying argon gas trapped in two-dimensional array of tiny 'cages'
For the first time, scientists have trapped a noble gas in a two-dimensional porous structure at room temperature. This achievement will enable detailed studies of individual gas atoms in confinement -- research that could inform the design of new materials for gas separation and nuclear waste remediation.

Nature Communications Mica provides clue to how water transports minerals
In a new study from the U.S. Department of Energy's (DOE) Argonne National Laboratory, in collaboration with the University of Illinois at Chicago and the University of Delaware, chemists have been able to look at the interface between water and muscovite mica, a flat mineral commonly found in granite, soils and many sediments. In particular, the researchers looked at the capture and release of rubidium - a metal closely related to but more easily singled out than common elements like potassium and sodium.
Public Release: 13-Jul-2017 Optimizing hydrogen-powered passenger ferries focus of Sandia Labs study
Maritime transportation has emerged as one solution to the traffic gridlock that plagues coastal cities. But with urban passenger ferries operating in sensitive environments and tourist areas, hydrogen fuel cell-powered passenger ferries offer a quiet, zero-emission alternative to conventional diesel vessels.
