Light-induced twisting of Weyl nodes switches on giant electron current

Scientists at the U.S. Department of Energy’s Ames Laboratory and collaborators at Brookhaven National Laboratory and the University of Alabama at Birmingham have discovered a new light-induced switch that twists the crystal lattice of the material, switching on a giant electron current that appears to be nearly dissipationless. The discovery was made in a category of topological materials that holds great promise for spintronics, topological effect transistors, and quantum computing.

DNA Origami Enables Fabricating Superconducting Nanowires

In AIP Advances, researchers describe how to exploit DNA origami as a platform to build superconducting nanoarchitectures. The structures they built are addressable with nanometric precision that can be used as a template for 3D architectures that are not possible today via conventional fabrication techniques. Inspired by previous works using the DNA molecule as a template for superconducting nanowires, the group took advantage of a recent bioengineering advance known as DNA origami to fold DNA into arbitrary shapes.

Scientists Say Farewell to Daya Bay Site, Proceed with Final Data Analysis

The Daya Bay Reactor Neutrino Experiment collaboration – which made a precise measurement of an important neutrino property eight years ago, setting the stage for a new round of experiments and discoveries about these hard-to-study particles – has finished taking data. Though the experiment is formally shutting down, the collaboration will continue to analyze its complete dataset to improve upon the precision of findings based on earlier measurements.

Batteries Mimic Mammal Bones for Stability

Sodium-ion batteries offer several advantages over lithium-ion batteries; however, it is difficult to develop sodium cathodes, materials through which electrons can enter a battery. Many candidate materials are unstable or cannot withstand high voltages. To find a solution, researchers turned to nature. They created a porous system of NVP structures, surrounded by a dense shell of reduced graphene oxide. They describe the mammal bone-inspired sodium cathode in the journal Applied Physics Reviews.
