Also known as “mermaid’s purses,” shark egg cases are both tough and permeable—two opposing characteristics that are necessary for the embryo’s survival. X-ray scattering at the ALS and electron microscopy helped explain how the material’s nanoarchitecture contributes to its toughness, informing future development of high-performance synthetic materials.

New Year’s Message from the Users’ Executive Committee
A warm welcome from the ALS Users’ Executive Committee 2022! We serve and represent the interests of the user community and provide a channel of communication and advocacy between the user community and ALS management. Read more »
Spectral Phenotyping for Early Detection of Alzheimer’s Disease
Early detection of Alzheimer’s disease may soon be within reach, thanks to spectral phenotyping. Using infrared spectroscopy, Berkeley Lab researchers developed this technique to detect the subtle biochemical changes in a “cellular fingerprint” that is characteristic of the devastating disease.

Reshaping the World of Research Through Remote Experimentation
At a time when the need was greater than ever, seven user research facilities formed a team of experts, the Remote Access Working Group (RAWG), to figure out how their institutions could keep the science going even when the researchers couldn’t access them in person. Read more »
March 2 Deadline for General User Proposals
The User Office is accepting new General User Proposals (GUPs) from scientists who wish to conduct research at the ALS in the 2022-2 (August–December) cycle. The deadline for submissions is March 2, 2022. Applicants are reminded that they may request joint access to the Molecular Foundry, a nanoscience user facility at Berkeley Lab, to support their ALS activities. Read more »
In Memoriam: Malcolm Howells, X-Ray Optics and Imaging Pioneer
Malcolm Richard Howells, a pioneer in x-ray optics and x-ray imaging, and an important contributor in the early days of the ALS, died on November 24, 2021. He will be deeply missed by all his colleagues and the generations of scientists that he trained and who now walk in his footsteps. Read more »
New UEC Members for 2022
Welcome to Connor Bischak, Sharon Bone, Wendy Gu, Yu He, and Quentin Williams. Thank you to Alex Fraño, Clemens Heske, and Antoine Wojdyla for your service.
DNA Synthesis: Flip It and Reverse It
What if the current model for DNA synthesis were flipped on its head? Using time-resolved x-ray crystallography, researchers gained new insights into this essential biological process, revealing that two steps in the synthesis pathway are, in reality, reversed. Read more »
How Iron Remediates Arsenic in Groundwater
Though iron has been demonstrated as an effective means to remediate arsenic contamination in groundwater, the mechanism was not well understood until now. For the first time, researchers have untangled the detailed steps of the interaction, informing more robust strategies for cleanup. Read more »
Update on Long-Term Operating Schedule
The operating schedule for the 2022-1 cycle has been published. The next long shutdown is expected to begin in January 2022 and last until mid-March. In the second cycle of 2022, we expect to have a total of eight weeks of shutdown time. The most up-to-date information on the current schedule and future outlook can always be found on the Operating Schedule web page. Read more »
