Giving Tuesday: Support the Future of Structural Science

On this Giving Tuesday, we invite our community—and anyone who believes in the power of structural science—to support the programs that keep the ACA strong and vibrant. You do not need to be an ACA member to donate.

Your gift helps fund student travel awards, educational workshops and courses, outreach initiatives, and the preservation of our history and video archives. Every contribution—large or small—makes a real impact on our members and the broader crystallographic community.

ACA President Gerald Audette visits LACA-ABCr 2025

ACA President Gerald Audette shares his highlights from the 7th LACA-ABCr 2025 meeting in Fortaleza, Brazil. From dynamic workshops and engaging plenaries to the strong sense of community across the Americas, his reflections capture the energy and impact of this year’s gathering. It’s a great look at the science, collaborations, and connections shaping crystallography in the region.

Share Your Work in Structural Dynamics

As a crystallographer, your research belongs at the heart of our community. Structural Dynamics—the official journal of the American Crystallographic Association and AIP Publishing—highlights cutting-edge discoveries in structure, dynamics, and emerging experimental methods. From time-resolved crystallography and XFEL studies to novel approaches in data analysis and materials science, SDY provides a platform where crystallographers and structural scientists can showcase innovation and impact. Publishing in SDY connects your work directly with an engaged global audience of crystallographers and allied scientists, ensuring visibility among peers who understand and value your contributions.

Right now, we’re especially inviting you to contribute to the special topic “Tribute to a Lifelong Innovator: John Markley and the Evolution of Biomolecular NMR,” with a submission deadline of December 31, 2025. Join your colleagues in advancing the frontiers of structural science—submit your next manuscript to Structural Dynamics.

Share Your Voice – ACA Member Engagement Survey

We want to hear from you! The ACA is hosting a Member Engagement Survey to learn what matters most to our community. Whether you’re interested in virtual workshops, mentoring, or networking opportunities, your feedback will help shape future programs and member benefits.

The survey takes just five minutes and is completely anonymous. At the end, you can choose to share your name if you’d like to get more involved.

Your input will help us build a stronger, more connected ACA.
