Study Finds ‘Missing Link’ in the Evolutionary History of Carbon-Fixing Protein Rubisco
Scientists discovered an ancient form of rubisco, the most abundant enzyme on Earth and critical to life as we know it. Found in previously unknown environmental microbes, the newly identified rubisco provides insight into the evolution of the photosynthetic organisms that underlie the planet’s food chains.

Targeting the trypanosome kinetochore with CLK1 protein kinase inhibitors
Saldivia et al. identify CLK1 as the target for the amidobenzimidazoles series of compounds. Inhibition of this protein kinase impairs inner kinetochore recruitment, causing cell-cycle arrest and cell death in trypanosomal pathogens such as Trypanosoma brucei. Read more »
Providing New Technologies for Vaccine Development
Antigens can sometimes be attached to a protein scaffold to mimic the shape of a virus and elicit a stronger immune response. Scientists developed a method to design such proteins, and ALS data helped to visualize the atomic structure and determine the dynamics of the designed scaffolds. Read more »
Scientists Capture Candid Snapshots of Electrons Harvesting Light at the Atomic Scale
A team of scientists has gained important new insight into electrons’ role in the harvesting of light in gold/TiO2 nanoparticle photoelectrochemical (PEC) systems. The scientists say that their study can help researchers develop more efficient material combinations for the design of high-performance solar fuels devices. Read more »
Summer 2020 Shutdown Recap
With all the changes due to COVID-19, it is no surprise that this summer’s ALS shutdown was also affected. It began later (August instead of July) and was shorter than originally scheduled (about six weeks instead of three months). Nevertheless a number of smaller activities, many in preparation for the ALS Upgrade (ALS-U), were accomplished. Read more »
ALS Beam Status App
Ed Rim, ALS accelerator and floor operator, has written an app for you to access the ALS beam status from your iOS device (iPhones and iPads). We have step-by-step instructions for downloading the app. Read more »
ALS User’s Congressional Testimony
As a user facility, the ALS team isn’t just our staff, but also our users around the world. Carnegie Mellon physics PhD student and ALS user Ryan Muzzio shared with Congress the impacts COVID has had on his research. Click on his name to read his words and play the video to view his testimony. Read more »
Sophie Morley, Research Scientist
Sophie Morley became an ALS staff member this July but started coming to the ALS as a user in 2012. Sophie likes to surf and mountain bike, but read more to find out what she really considers to be her playground. Read more »
Understanding Electronic Structure in MXenes, One Atomic Layer at a Time
MXenes are 2D materials that can host a rich array of distinct chemical compositions that can be tuned for a broad range of applications, from energy storage to water purification. Site-specific x-ray absorption spectroscopy helped identify the unique roles of surface and subsurface transition-metal atoms in Ti-based MXenes. Read more »
