New Technique Visualizes Every Pigment Cell of Zebrafish in 3D
Researchers developed a new technique that uses x-ray microtomography and silver staining to image every pigment cell of a whole zebrafish in 3D. The method could be used to learn more about the 3D architecture of melanoma tumors and potentially guide treatment decisions. Read more »
New Device Advances Commercial Viability of Solar Fuels
A Berkeley Lab research team developed a new artificial photosynthesis device component that exhibits remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels—ethylene and hydrogen. Read more »
Nanoscale Confinement of Photo-Injected Electrons at Hybrid Interfaces
Picosecond time-resolved x-ray photoemission spectroscopy provides real-time electron distributions of donors and acceptors in a prototypical bipyridyl-ZnO hybrid light harvesting system. The measurements show that photo-injected electrons remain localized within the defect-rich surface region of the nanoporous ZnO substrate, revealing a challenge for the extraction of free charge carriers.

Kenneth Goldberg Named 2022 Optica Fellow
Kenneth Goldberg, a staff scientist at the ALS and with the ALS-U Project, has been elected a 2022 Fellow of Optica (formerly OSA). His recognition is “for seminal contributions to the development of x-ray optics for applications requiring coherent light.” Read more »
Advanced Light Source Upgrade Project Achieves Major Milestone
The ALS Upgrade (ALS-U) Project has received federal “CD-2” approval for its budget, schedule, and technical scope. The upgrade will boost the brightness of ALS soft x-ray beams at least a hundredfold. Read more »
Materials from Town Hall on Shutdown Schedules Now Available
On January 26, the ALS held a town hall on the schedule for upcoming long shutdowns. The event provided up-to-date information on the schedule, explained the motivations behind decisions, and discussed principles and strategies for future decision-making. Slides and a recording from the event, as well as an FAQs document, are posted to the ALS website. Read more »
New ALS Mission Statement and Core Values
The ALS has refreshed its mission statement and established a set of core values. Developed through a collaborative process led by the ALS Inclusion, Diversity, Equity, and Accountability Committee, the mission and values will guide ALS strategy and practices and shape our working environment and culture for staff, users, and other visitors who are part of our community.
