Scientists at Pfizer created Paxlovid, a new drug candidate that proved to be effective against the SARS-CoV-2 virus, which causes COVID-19, with the help of the U.S. Department of Energy’s (DOE’s) Advanced Photon Source at the DOE’s Argonne National Laboratory.
The cycle of rising temperatures leads to increases in precipitation as well as droughts. What impact will these weather extremes have on Earth’s most effective water cleansers: wetland sediments? That question drives a $1 million, three-year U.S. Department of Energy grant awarded to a Georgia Institute of Technology research team of geochemistry, biology, and applied mechanics experts. Georgia Tech sediment samples will be examined at the atomic scale of individual atoms and electrons the DOE Office of Science's Advanced Photon Source.
Perrin Godbold is exploring green energy by trying to understand its most basic elements. The doctoral student in chemistry, nanomaterials, and electrocatalysis at the University of Virginia received a U.S. Department of Energy Science Graduate Student Research Award to work at the Advanced Photon Source.
The Advanced Photon Source will hold a virtual town hall for users interested in the project to construct the Polarization Modulation Spectroscopy (POLAR) feature beamline at 4-ID. The town hall runs from 10 a.m. to noon CDT on Friday, November 12, 2021. 
The U.S. Department of Energy’s (DOE's) Argonne National Laboratory has named Laurent Chapon as associate laboratory director for Photon Sciences and director of the Advanced Photon Source, a DOE Office of Science User Facility at Argonne.
Michael Kelly is a group leader in the Argonne Physics Division, and he has extensive experience designing components for accelerators. So when the people behind the upgrade of the APS were looking for someone with just that kind of experience to help them build the state-of-the-art electron storage ring that will be at the heart of the new facility, they knew where to find him.
The Advanced Photon Source will hold a virtual town hall for users interested in the project to construct the High-Energy X-ray Microscope feature beamline at 20-ID in the Long Beamline Building. The town hall runs from 10 am to 12 noon CDT on Monday, October 25, 2021. 
In preparation for the APS Upgrade, modifications were needed to the radiation shielding in the particle accumulator ring. The team expertly completed the job ahead of the estimated time needed.
Using APS x-rays, scientists will study tiny specks of asteroid 162173 Ryugu, collected by a Japanese space mission. Learning more about how this asteroid formed will further our understanding of the solar system, including Earth’s formation.
Laura Greene has been appointed by President Biden to serve on the President's Council of Advisors on Science and Technology. Greene is the chief scientist at the National High Magnetic Field Laboratory located at Florida State University, the University of Florida, and Los Alamos National Laboratory; and a member of the Advanced Photon Source Scientific Advisory Committee.
To provide x-ray beams that are both very bright and very tightly focused, an Advanced Photon Source (APS) team had to create a new system of mirrors, lenses and equipment for the upgraded APS.
In some ways, it’s no surprise Jie Liu grew up to be an engineer. She’s following in the footsteps of her father, who made engineering his career. From a young age, she said, she was fascinated by the big machines her father worked on, and she would take bicycles apart and put them back together, learning how they worked. Now she works as a principal mechanical engineer on the upgrade of the Advanced Photon Source, a DOE Office of Science user facility at Argonne.
You are invited to participate in a workshop on “Data Handling at the APS Coherent High-Energy X-ray (CHEX) Sector.” This online workshop will be held via Microsoft Teams on Thursday and Friday, October 21 and 22, 2021.
The Advanced Photon Source will hold a virtual town hall for users interested in the project to construct the Coherent Surface Scattering Imaging (CSSI) feature beamline at 9-ID. The town hall runs from 1:00 p.m. to 3:00 p.m. CDT on Wednesday, October 6, 2021.
The APS will hold a virtual town hall for users interested in the project to construct the X-ray Photon Correlation Spectroscopy feature beamline at 8-ID. The town hall runs from 10:00 a.m. to 12:00 p.m., CDT, on Monday, September 20, 2021.
The most visible sign that the APS Upgrade Project is proceeding is the Long Beamline Building, home to two of the stations where researchers will carry out cutting-edge science experiments using the brighter x-ray beams. Construction of this new building has progressed ahead of schedule since its groundbreaking ceremony on July 22, 2020, and is on track for completion in June 2022.
The Advanced Photon Source is holding a virtual town hall for users interested in the project to construct the Advanced Spectroscopy and LERIX (ASL) beamline at 25-ID. The town hall began at 10:00 a.m. CDT today, Wednesday, September 1, 2021.
The APS/IIT 2021 XAFS Virtual Summer School was successfully held Aug 1-4 2021 online. This was a joint effort of IIT and the Advanced Photon Source and beamline staff.  More than a dozen people from ANL and IIT served as synchronous instructors, including Steve Heald, Matt Newville, Shelly Kelly, and other beamline scientists from the APS, and Grant Bunker, Carlo Segre, and Jeff Terry from IIT Physics Department. 
The 1,000th magnet for the Advanced Photon Source Upgrade has arrived at Argonne.  The 1,000th magnet is an eight-pole fast corrector magnet, which is used to alter the trajectory of the electron beam as it circulates around the storage ring at nearly the speed of light.
A feature story on the Argonne home page notes that "For more than 25 years, the Advanced Photon Source’s intense X-rays have enabled important breakthroughs. With a massive upgrade in the works, scientists will be able to see things at scale never seen before." The article provides a comprehensive look at the APS past, present, and future, including the role APS users played in the fight against COVID-19.
