Researchers have discovered that “Fermi arcs,” much-debated features found in the electronic structure of high-temperature superconducting (HTSC) cuprates, can also be found in an iridate (iridium oxide) compound—strontium iridate. Read more »
Two research groups have recently published separate studies in which soft x-rays reveal how skyrmions—quasiparticles made up of spin vortices—react to external fields. Their work lays the foundation for understanding these fascinating constructs and eventually utilizing them in spintronic applications. Read more »
New studies of space dust captured by NASA’s Stardust Interstellar Dust Collector have shown that interstellar particles may be much more complex in structure and composition than previously thought. Read more »
A pathway to more effective and efficient synthesis of pharmaceuticals and other flow-reactor chemical products has been opened by a study in which, for the first time, the catalytic reactivity inside a microreactor was mapped in high resolution from start to finish. Read more »
Computationally designed proteins that accurately mimic key viral structures can help produce better vaccines. The resulting protein structures, validated at the ALS, encourage the further development of this strategy for a variety of vaccine targets, including HIV and influenza. Read more »
Researchers studying organic material from dinosaur bones have been able to show that the samples contained original soft tissue material from Mesozoic dinosaurs. The x-ray techniques at the ALS were key to showing a possible mechanism for this unexpected preservation.

The molecular structures of two proteins from a family of genome-editing enzymes reveal how they target and cleave DNA. The results point the way to the rational design of new and improved versions of the enzymes for basic research and genetic engineering. Read more »
ALS researchers have discovered a material that is essentially a 3D version of graphene — the 2D sheets of carbon through which electrons race at many times the speed at which they move through silicon. The discovery promises exciting new things to come for the high-tech industry, including much faster transistors and far more compact hard drives. Read more »
A new broadband imaging technique looks inside the mesoscale realm with unprecedented sensitivity and range. Synchrotron Infrared Nano-Spectroscopy (SINS) will enable in-depth study of complex molecular systems, including liquid batteries, living cells, novel electronic materials, and stardust.
