Here is Northwestern University's press release on the Genesis Mission projects they are contributing to, including the Argonne-led CMOS + X. Professor Jie Gu will serve as Northwestern's PI on this project. https://bit.ly/44EUoSH

Congratulations to APS scientists Robert Von Dreele and Brian Toby on receiving the 2026 Neutron Scattering Society of America Service Award! Their GSAS software has helped researchers transform complex data into discoveries across many different fields of study. www.aps.anl.gov/APS-News/202...

Science Friday! Scientists have combined powerful X-rays with machine learning to reveal patterns in how stainless steel deforms under stress. This could help researchers design more durable metals by uncovering the microscopic defects that control their strength. www.aps.anl.gov/APS-Science-...

ICYMI: Researchers have created a blueprint for designing next-generation cancer therapies that target multiple RAS proteins at once, potentially improving outcomes for patients with KRAS-driven cancers. www.aps.anl.gov/APS-Science-...

Researchers at the APS developed a new imaging system that creates detailed temperature maps while collecting X-ray diffraction data. This advance will help researchers study how materials melt and transform under the extreme conditions found deep inside planets. www.aps.anl.gov/APS-Science-...

Science Friday! Farhad Fatakia has been collecting ancient coins from the time of the Persian empire for years. These coins contain no date markings. To learn more about when and where they were made, Fatakia brought his coins to the APS to identify the elemental composition of their base metals.

A new catalyst could make it easier to turn methane and carbon dioxide into fuels and industrial chemicals. Using X-rays, researchers revealed how the catalyst can stay active for days at the extreme temperatures needed for the reaction. www.aps.anl.gov/APS-Science-...

Join us in wishing the United States of America a happy 250th!

Happy 80 years and one day, Argonne. Read more about the history and achievements of America's first national lab - including the world's first usable electricity from nuclear energy, in 1951 (see photo!). https://www.anl.gov/article/eighty-years-and-counting-of-scientific-discovery-at-argonne

Happy birthday to the first national laboratory in the U.S. Argonne remains at the forefront of scientific discovery with immediate impact on the country and the world. We at Argonne's APS are thrilled to celebrate this milestone and we look forward to the future!

Here are a few photos from Argonne's Open House over the weekend, taken at the Advanced Photon Source. More to come! Thank you to everyone who braved the heat and showed up to learn more about the APS and the lab. We appreciate you all!

There are still some free tickets available for the Argonne Open House, which takes place on Saturday from 9 am to 4 pm. Register at the link below! web.cvent.com/event/292b5c...

Cancer cells often find ways around drugs designed to stop them. Researchers have uncovered key structural differences between two cancer-driving proteins, revealing a path toward a single drug that could block both and help prevent treatment resistance. www.aps.anl.gov/APS-Science-...

For more than 30 years, a record in science held firm: minus 220 degrees Fahrenheit. It defined the highest achieved temperature for any material to become superconducting without the need for crushing pressures. Now the record has shifted. www.anl.gov/article/supe...

Science Friday! Scientists have developed a new way to assemble gold nanoparticles into open, crystal-like structures that were once thought to require specially engineered “patchy” particles. www.aps.anl.gov/APS-Science-...

On July 1 Argonne National Laboratory turns 80 years old. Read more about the future of the lab's science, including the upgraded APS, in this article: www.anl.gov/article/afte...

Scientists have uncovered why changing the gas used in metal 3D printing can reduce defects in finished parts. Using high-speed X-ray and thermal imaging at the APS, they found that gas density plays a key role, opening new possibilities for improving additive manufacturing. https://bit.ly/4eeQwxd
