Two molecules can contain the same atoms, connected in the same way, yet behave differently because of their three-dimensional arrangement. The 2026 Nobel Prize in Chemistry celebrates discoveries that help explain—and control—this molecular “handedness,” a subject closely connected to crystallography.
The ACA congratulates Francis Halzen, recipient of the 2026 Nobel Prize in Physics, for his contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos from astrophysical sources.
The American Crystallographic Association joins the international scientific community in mourning the passing of Professor Ada Yonath, Nobel laureate and pioneering structural biologist, who died on August 31, 2026, at the age of 87.
The American Crystallographic Association (ACA) is pleased to announce the recipients of three of its highest honors for 2027. These awards recognize outstanding achievements in crystallographic research, structural science, and diffraction physics, as well as the individuals whose work continues to advance our understanding of the structure of matter.
Celebrating Excellence in Structural Dynamics: Elina Elvelo Recognized at the 2026 BCA Meeting
It is a tremendous honor to serve as the new President of the American Crystallographic Association. I look forward to working with our outstanding community and continuing the ACA’s tradition of scientific excellence, collaboration, and collegiality.
The crystallographic community mourns the loss of Dr. Benno P. Schoenborn, who passed away on September 23, 2025, in Phoenix, Arizona.
The American Crystallographic Association proudly recognizes three outstanding scientists whose work is advancing the frontiers of structural science:
Spring is coming soon! Every year, on the 1st of April, the ACA collects nominations for its Fellows program. When I was elected a 2021 ACA Fellow, to be honest, I hadn’t put much thought into why professional organizations bother to make such distinctions. Certainly, being elected a Fellow is an honor and welcome recognition for any individual, but why do we, the ACA, The Structural Science Society, promote this type of recognition?
