X-ray Crystal Structures of the Influenza M2 Proton Channel Drug-Resistant V27A Mutant Bound to a Spiro-Adamantyl Amine Inhibitor Reveal the Mechanism of Adamantane Resistance
The M2 proton channel, shown with front and back monomer helices removed, is an anti-influenza drug target. Here, a bound inhibitor blocks the transport of protons through the V27A mutant channel. Read more »
Scientists Discover New Clue Behind Age-Related Diseases and Food Spoilage
Scientists at Berkeley Lab have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time. The findings point to an unexpected link between the ozone chemistry in our atmosphere and our cells’ hardwired ability to ward off disease. Read more »
Highly Permeable Perfluorinated Sulfonic Acid Ionomers for Improved Electrochemical Devices: Insights into Structure-Property Relationships
Perfluorinated sulfonic acid ionomers (PFSAs) induce significant mass-transport limitations in proton exchange membrane fuel cell catalyst layers due to their semicrystalline PTFE-based matrix. We present a novel PFSA with an amorphous perfluorinated matrix, which vastly improves gas permeability, reduces transport resistance, and improves catalyst utilization in functional catalyst layers.

July 2020 Shutdown Preview
The ALS will be undergoing longer shutdowns in preparation for the ALS-U dark period. Although beam will not be available for users, the flurry of activity at the ALS will continue, and many projects are scheduled for the upcoming shutdowns. ALS Deputy for Accelerator Operations Fernando Sannibale gives us a preview of this summer’s shutdown. Read more »
Winter 2020 Shutdown Recap
Many projects around the ALS were completed during the Winter 2020 shutdown. Some of these improvements will benefit users now, and others provide additional utility that will be required in the future. In response to user feedback, we have endeavored to divide projects into the smallest possible segments in order to decrease the amount of time required for each shutdown. Read more »
Alex Frano, Assistant Professor and UEC Chair
As a light source user, Alex Frano loves the camaraderie of beamtime, and he is excited to build on that sense of scientific collegiality as this year’s Users’ Executive Committee chair. You may have seen him on the experimental floor or at the User Meeting, but do you know his secret talent? Read more »
February 2020 Message from the Users’ Executive Committee
The 2020 UEC Chair Alex Frano highlights the new date of the User Meeting, which will be August 25–27 this year. This year’s meeting will continue the tradition of excellent speakers, tutorials, and workshops. Read more »
Can Minerals in the Earth’s Lower Mantle Store Water?
Earth is considered a watery planet, simply by virtue of the fact that 71% of its surface is covered by oceans. But researchers have discovered that, in the massive volume of material in Earth’s interior, minerals can serve as an important water reservoir, providing a new perspective on our planet’s water budget.

Water Improves Material’s Ability to Capture CO2
With the help of the ALS, researchers from UC Berkeley and ExxonMobil fine-tuned a material to capture CO2 in the presence of water. The parties have applied for a patent on the material, which was developed for use on the relatively humid flue gases emitted by certain natural gas power plants, a cleaner-burning alternative to coal.
