Researchers found that type 2 diabetes induces earlier onset of plastic (nonrecoverable) deformation in intervertebral discs by impairing the biomechanical behavior of collagen. A greater understanding of the underlying causes of tissue failure in diabetes—a growing problem worldwide—is important in helping to prevent and treat symptoms. Read more »

Researchers identified the dominant chemical state of active sites in a cobalt-based catalyst using resonant photoemission spectroscopy under realistic conditions. The work will help scientists develop more-efficient catalysts for removing noxious carbon monoxide gas from exhaust streams generated by the burning of fossil fuels. Read more »
A time-resolved study using infrared spectromicroscopy in a carefully controlled environment revealed why enzymes get bogged down when trying to break up cellulose from plants. The work sheds new light on the challenge of extracting the sugars locked up in plants for use in making petroleum-free fuels, chemicals, and medicines. Read more »
From the microscope at work to the telescope at home, Matthew Marcus is captivated by space sciences. In this interview, he shares some of the findings from Beamline 184.108.40.206 as well as stories from his long career in x-ray science. Read more »
Don’t miss the 2024 ALS User Meeting featuring invited speakers, hands-on workshops, tutorials, and a potential collaborative workshop with the ALS and Molecular Foundry. Exciting discussions await, so mark your calendars for August 12–14. Read more »
Research from Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, and UC Davis sheds new light on how to access the sugars locked up in plants to produce petroleum-free fuels, chemicals, and medicines. The technique used combines a novel microfluidic device and infrared spectroscopy to study how a cellulose-degrading enzyme works in real time. Read more »
Living in the Santa Cruz mountains, Quentin Williams spends a lot of time tending to projects on the Earth’s surface, but his professional interests lie thousands of kilometers below. His geosciences research led him to become a long-time user of the ALS, where he is serving as the UEC chair for 2024. Learn more about his work and hear his advice for other ALS users. Read more »
In recognition of a lack of representation for the biosciences on the Users’ Executive Committee, a special election was held in accordance with UEC bylaws, and Grant Shoffner was selected to represent the biosciences community for a one-year term (2024).
Using the ALS, researchers found quantitative correlations between processing parameters and the structure of ultrafine, polymer-reinforced carbon-nanotube fibers. The work will facilitate the production of high-strength materials, including those needed for positioning target capsules for fusion research at the National Ignition Facility. Read more »
ALS scientific staff and partners held a retreat on January 11 to continue the strategic planning process. Discussions centered around ideas presented at last September’s User Meeting visioning workshops. Stay tuned for the visioning report and ways you can take part in the future of the ALS!
