During a series of experiments at the ALS, researchers identified helical magnetic spins that fluctuate at different time scales during a phase transition as a function of temperature in a nematic iron germanium thin film. The results provide a framework for characterizing exotic phases, which may have interesting optical and transport properties for microelectronics and spintronics. Read more »
ALS Work Using Scattering/Diffraction
These techniques make use of the patterns of light produced when x-rays are deflected by the closely spaced lattice of atoms in solids and are commonly used to determine the structures of crystals and large molecules such as proteins.
Characterizing Membrane Fouling with Operando Experiments
Membrane filtration offers a cost-effective, energy-efficient approach to purify and desalinate water, but fouling limits the performance of these devices. A new study explored the new experimental design that allows one to study the dynamic fouling process in real time to improve the field’s understanding of how materials deposit, accumulate, and/or crystallize on the membrane’s surface.

Sharks Shed Light on Origins of Adaptive Immune System
A team of researchers identified the three-dimensional structure of a protein expressed by a gene of a modern nurse shark that is proposed to be a close homologue to a gene that, more than 500 million years ago, gave rise to the adaptive immune system shared by all vertebrates. By understanding the emergence and evolution of the immune system, researchers may advance work in immunology, genetics, and biotechnology. Read more »
Stable 2D Interlayer Prolongs Perovskite Devices
Layered 2D/3D perovskite bilayer heterostructures have the potential to boost the performance and durability of many types of electronic and photonic devices, but maintaining this performance depends on the stability of the cell’s 2D interlayer. In this study, researchers optimized time-resolved, spontaneous thin-film deposition of 2D perovskites using a mixed solvent approach to produce phase pure, stable thin films with high crystallinity.

Researchers Identify Viral Swiss Army Knife, Clarifying How Replication Occurs
Viruses are ingenious, infectious agents, capable of replicating inside the living cells of a host organism. Enterovirus, a common viral pathogen, is responsible for a range of diseases from mild colds to severe conditions, including viral meningitis, myocarditis, and paralysis. A new study sheds light on how enteroviruses use structured RNA elements and multifunctional proteins to coordinate viral replication efficiently using minimal genetic material. Read more »
Operando probing dynamic migration of copper carbonyl during electrocatalytic CO2 reduction
In their work, Peidong Yang and colleagues reveal the dynamic evolution from faceted Cu nanocatalysts into metallic nanograins during CO2 reduction driven by the surface migration of electrogenerated copper carbonyl. Read more »

Researchers use the ALS to confirm the structure of an engineered immune protein that could open new opportunities to treat inflammatory bowel disease. Read more »
From Sequence to Structure: A Fast Track for RNA Modeling
RNA isn’t just a genetic messenger—it also folds into complex shapes to drive vital biological processes. Scientists are just starting to understand the many functions of these molecules, and how we can harness them for applications in environmental science, agriculture, and medicine. A powerful new RNA structure prediction tool is here to help. Read more »
Building a Gated-Access Fast Lane for Ions
In organic conductors where charge is carried by both electrons and ions, scientists have discovered a way to make the ions move more than ten times faster than in comparable ion-transport methods. The results could apply to a host of areas, including improved battery charging, biosensing, soft robotics, and neuromorphic computing. Read more »
Deep-Dive Inspection of a Molecular Assembly Line
By locking down certain movable parts of a modular drug-building protein, researchers learned new details about how carrier proteins transfer the product protein between modules. The results offer insights that could enable scientists to design and create new and improved medicines, such as antibiotics, using synthetic biology. Read more »
