Researchers demonstrated the synthesis of a thermodynamically stable compound of argon and nickel at temperatures and pressures representative of the Earth’s core. The ability of argon, a noble gas, to react with other elements under these conditions may help solve outstanding geological questions, including the “missing argon paradox.” Read more »

Warm Coat Drive at the ALS and Molecular Foundry
We are joining forces with the Molecular Foundry to collect clean, new or gently-worn coats for Alameda County Social Services. Now through December 19, you can donate your coats to boxes in the lobby of Building 6 or 67. Last year, we collected 93 coats! Contacts: Cindy Lee (ALS) and Suksham Barun (Molecular Foundry) Read more »
A High-Pressure Compound of Argon and Nickel: Noble Gas in the Earth’s Core?
Researchers demonstrated the synthesis of a thermodynamically stable compound of Ar and Ni at thermodynamic conditions representative of the Earth’s core. The results suggest that the abundance of Ar in the Earth’s core is beyond a simple solubility of Ar in molten Ni–Fe but in chemical reactions in nature. Read more »
The Beauty of Imperfections: Linking Atomic Defects to 2D Materials’ Electronic Properties
Two studies reveal surprising details on how some atomic defects emerge in transition metal dichalcogenides (TMDs), and how those defects shape the material’s electronic properties. The findings could provide a more platform for designing 2D materials for quantum information science and smaller, more powerful optoelectronics. Read more »
Machine Learning Helps Stabilize Synchrotron Light
Researchers showed that machine learning can predict noisy fluctuations in the size of beams generated by synchrotron light sources and correct them before they occur. The work solves a decades-old problem and will allow researchers to fully exploit the smaller beams made possible by recent advances in light source technology. Read more » 
Scientists Explore Egyptian Mummy Bones With X-Rays and Infrared Light to Gain New Insight on Ancient Life
Researchers from Cairo University worked with teams at the ALS to study soil and bone samples dating back 4,000 years. The experiments are casting a new light on Egyptian soil and ancient mummified bone samples that could provide a richer understanding of daily life and environmental conditions thousands of years ago.

Machine Learning Enhances Light-Beam Performance at the Advanced Light Source
Researchers have successfully demonstrated how machine-learning tools can improve beam-size stability via adjustments that largely cancel out these fluctuations—reducing them from a level of a few percent down to 0.4 percent, with submicron precision. The demonstration shows that the technique could be viable for scientific light sources around the globe. Read more »
