The American Crystallographic Association is pleased to share news from our publishing partnership with AIP Publishing: Structural Dynamics is entering a new chapter with the appointment of Mark Wilson as Editor-in-Chief.
The American Crystallographic Association is deeply grateful to Virginia Pett, who is concluding her service as ACA Historian. Virginia’s dedication, care, and steady leadership have played a vital role in preserving the history of our Association and ensuring that ACA’s legacy remains accessible to current and future generations.
Earlier this month, we hosted a We’re Listening session to discuss the results of the Future Meetings Survey. The conversation was thoughtful and productive, and it gave us valuable context beyond the survey data alone.
I recently had the opportunity to attend the 7th Latin American Crystallographic Association and 27th Brazilian Crystallographic Association (LACA-ABCr 2025), which was held between October 14-17, 2025, in Fortaleza, Brazil. I was looking forward to this meeting for some time and learning more of research across the structural sciences community in the broader Americas.
We are pleased to share that the American Crystallographic Association (ACA) has been invited to participate in a new national initiative — REV UP, led by the American Association of Physics Teachers (AAPT) and funded by the AIP Venture Fund.
CSD Communications is a way to share small molecule crystal structures directly in the Cambridge Structural Database (CSD) without requiring an associated scientific publication.
Applications for the 2026 ACA Summer Course will open in December 2025, and we encourage anyone passionate about crystallography to apply.
We wanted to share a quick update about our presence on the platform X. While the ACA account will remain available, it won’t be actively monitored moving forward. Over the past year, many in the scientific community have moved away from X, and we’ve seen engagement there drop off significantly. Because of this, it’s no longer the best place for us to connect with you.
The beginning of September is always something I look forward to. While it is a soft goodbye to summer, sitting under a tree on a warm fall afternoon with the leaves changing colors and reading something interesting has been something I’ve enjoyed for many years. Perhaps it will be the e-version of RefleXions for me this year :). And of course, for those of us in the academic sector, it is the start of the new fall academic term, with our campuses abuzz with new and returning students. I wish you all the best on the start of autumn, a new semester, and new or ongoing scientific pursuits.
We’re pleased to announce the American Association to Advance Powder Diffraction (AAAPD), a grassroots organization that was formed to be a voice for the powder diffraction community to ensure a bright future for this field.
The 2025 Nobel Prize in Physics was awarded jointly to John Clarke (UC Berkeley), Michel H. Devoret (Yale/UC Santa Barbara), and John M. Martinis (UC Santa Barbara) “for the discovery of macroscopic quantum mechanical tunneling and energy quantization in an electric circuit."
The 2025 Nobel Prize in Chemistry has been awarded to Richard Robson, Susumu Kitagawa, and Omar M. Yaghi for the development of metal–organic frameworks (MOFs) — remarkable crystalline materials that are transforming how we capture, store, and use molecules.
The crystallographic community mourns the loss of Dr. Benno P. Schoenborn, who passed away on September 23, 2025, in Phoenix, Arizona.
The ACA community mourns the loss of Dr. David Duchamp, who passed away peacefully at home with his family on August 15, 2025, at the age of 85.
We are at a pivotal moment for U.S. structural science. The National Academy of Sciences (NAS) has announced that, effective January 1, 2026, it will withdraw from the International Union of Crystallography (IUCr) and dissolve the U.S. National Committee for Crystallography (USNC/Cr). This action ends a long tradition of national representation and threatens the continuity of U.S. engagement with the global crystallography community.
The American Crystallographic Association proudly recognizes three outstanding scientists whose work is advancing the frontiers of structural science:
