Last month, we published our fifth print issue of the year for Spectroscopy. A major theme of our September/October 2025 issue is the evolution of chemometrics, detailing the progression from classical statistical methods to modern artificial intelligence (AI) and machine learning (ML) techniques for complex chemical data analysis. One article specifically honors Bruce R. Kowalski, acknowledged as a founding figure in chemometrics, highlighting his contributions to theory, education, and the founding of relevant institutions and journals. Additionally, our Emerging Leader in Molecular Spectroscopy feature offers a deep dive into the career of Lingyan Shi, the 2025 Emerging Leader in Molecular Spectroscopy, who is recognized for her work in multimodal molecular imaging using techniques like Stimulated Raman Scattering (SRS).

Atomic spectroscopy has quietly gone from counting elements in bulk to counting single nanoparticles, imaging tissue at the micrometer scale, and reading Martian rocks from several meters away. The instruments got smaller, the software got smarter, and the questions they can now answer got a lot more interesting.
