Communications Committee Update

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.

President's Column - Fall 2025

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.
