Engineering phase changes in nanoparticle arrays
Scientists at the US Department of Energy's Brookhaven National Laboratory have just taken a big step toward the goal of engineering dynamic nanomaterials whose structure and associated properties can be switched on demand. In a paper appearing in Nature Materials, they describe a way to selectively rearrange the nanoparticles in three-dimensional arrays to produce different configurations, or phases, from the same nano-components.

DNA double helix does double duty in assembling arrays of nanoparticles
In a new twist on the use of DNA in nanoscale construction, scientists at the US Department of Energy's Brookhaven National Laboratory and collaborators put synthetic strands of the biological material to work in two ways: They used ropelike configurations of the DNA double helix to form a rigid geometrical framework, and added dangling pieces of single-stranded DNA to glue nanoparticles in place.

Visualizing how radiation bombardment boosts superconductivity
Study shows how heavy-ion induced atomic-scale defects in iron-based superconductors 'pin' potentially disruptive quantum vortices, enabling high currents to flow unimpeded. The study opens a new way forward for designing and understanding superconductors that can operate in demanding high-current, high magnetic field applications, such as zero-energy-loss power transmission lines and energy-generating turbines.

Uncovering the mysteries of cosmic explosions
An automated software system developed at Los Alamos National Laboratory played a key role in the discovery of supernova iPTF 14atg and could provide insight, a virtual Rosetta stone, into future supernovae and their underlying physics.

Sandia researchers first to measure thermoelectric behavior by 'Tinkertoy' materials
Sandia National Laboratories researchers have made the first measurements of thermoelectric behavior by a nanoporous metal-organic framework, a development that could lead to an entirely new class of materials for such applications as cooling computer chips and cameras and energy harvesting. The results were published in 'Thin Film Thermoelectric Metal-Organic Framework with High Seebeck Coefficient and Low Thermal Conductivity,' which appeared April 28 online in Advanced Materials.

Supernova hunting with supercomputers
Type Ia supernovae are famous for their consistency. Ironically, new observations suggest that their origins may not be uniform. Using a 'roadmap' of theoretical calculations and supercomputer simulations performed by Berkeley Lab's Daniel Kasen, astronomers observed a flash of light caused by a supernova slamming into a nearby star, allowing them to determine the stellar system from which the supernova was born. This finding confirms one of two competing theories about Type Ia supernovae birth.

Drought-induced tree mortality accelerating in forests
Researchers at Los Alamos National Laboratory have found that drought and heat-induced tree mortality is accelerating in many forest biomes as a consequence of a warming climate in their paper 'Darcy's law predicts widespread forest mortality under climate warming,' published in the journal Nature Climate Change.

Starving cancer cells instead of feeding them poison
An enzyme-drug that prevents the essential nutrient asparagine from reaching cancer cells seem an effective way to kill them, but that enzyme-drug also does away with the nutrient glutamine that all cells need. Now a simulation has directed the mutation of the enzyme so that, in wet labs, it left normal cells unharmed in Petri dishes and cancer cells dead in test tubes. Lab tests are underway with mice. If successful, human tests are next.
