In Memoriam: Brian Kincaid, Former ALS Director

Brian Kincaid, the first director of the Advanced Light Source, died on January 1, 2022. The ALS community sends our condolences to his family and honors the many contributions he made to the early years of our facility. Read more »

What Drives Electron–Hole Asymmetry in Graphene?

Using the ALS, researchers determined that interactions between electrons are what give rise to the divergent effects observed when graphene is doped with electrons versus holes. A better understanding of this electron–hole asymmetry could lead to new avenues for generating exotic material phases, including unconventional superconductivity. Read more »PPT-icon-35 PDF-icon-35

Molecular Hijacking of a MicroRNA by the Hepatitis C Virus

The hepatitis C virus (HCV), which attacks the liver, is known to repurpose host-cell components known as microRNAs—short RNA strands that act to silence gene expression. Now, the molecular structure of an HCV site bound to a microRNA complex revealed how their interactions shield the virus from the host cell’s protective response. Read more »

Scientists Uncover Surprising New Clues to Exotic Superconductors’ Superpowers

Researchers studied a model material (CeCoIn5) that mimics a cuprate superconductor that can be switched on and off using high magnetic fields. In chemical compositions where the superconductivity is strongest, the number of free electrons jumps, signifying a transition point. The researchers attributed this transition to the behavior of electrons associated with the cerium atoms. Read more »

A Brighter Future for Stretchable Electronics

By continuously monitoring physiological signals, wearable “stick-on” sensors not only help people stay healthy, they can also provide early warning of potential health problems. At the ALS, researchers studied the morphology of such a sensor’s active material, which is key to controlling and optimizing its structure and performance. Read more »
