Researchers utilize Raman spectroscopy to uncover the lost colors of prehistoric mollusk shells, revealing their cultural significance and aesthetic choices.

A recent study explored a novel approach to analyze ancient food and wine residues using FT-IR spectroscopy.

Recently, a team of researchers from Chongqing University (China) developed a new Raman spectroscopy technique that could significantly improve natural gas monitoring and leak detection systems.

Astronomers have conducted detailed spectrophotometric observations of the mysterious interstellar comet 3I/ATLAS using the Palomar 200-inch and Apache Point telescopes. The findings reveal unexpected activity and unique spectral features, enhancing our understanding of this cosmic visitor.

As part of our coverage of Analytica USA, Spectroscopy sat down with Ian Ciesniewski, technical director at Mettler Toledo, to discuss the latest changes made to the United States Pharmacopeia (USP) Chapters 41 and 1251. In this interview segment, Ciesniewski discusses how the recent changes to these two chapters will impact organizations.

The interstellar object 3I/ATLAS, discovered in July, has captivated astronomers with its unusual characteristics. While some scientists attribute its behaviors to natural cometary processes, others propose more speculative theories, including the possibility of it being an artificial probe. This article examines both mainstream and speculative interpretations of 3I/ATLAS's anomalous features. Other news articles this week will look specifically at the spectroscopic results of telescopes recently analyzing this mysterious object.

This tutorial explores the challenges posed by nonlinearities in spectroscopic calibration models, including physical origins, detection strategies, and correction approaches. Linear regression methods such as partial least squares (PLS) dominate chemometrics, but real-world data often violate linear assumptions due to Beer–Lambert law deviations, scattering, and instrumental artifacts. We examine extensions beyond linearity, including polynomial regression, kernel partial least squares (K-PLS), Gaussian process regression (GPR), and artificial neural networks (ANNs). Equations are provided in full matrix notation for clarity. Practical applications across near-infrared (NIR), mid-infrared (MIR), Raman, and atomic spectroscopies are discussed, and future research directions are outlined with emphasis on hybrid models that integrate physical and statistical knowledge.

A recent study examined how portable instrumentation could be applied in the detection of diabetes.

Recently, a team of researchers from Portugal examined a new method that could improve accessibility to kidney disease diagnostics.

Despite decades of major monetary investment for applied research in multiple spectroscopic sensing technologies, achieving an accurate, portable, and painless noninvasive glucose monitor remains a major unmet goal in diabetes care. This goal is extremely difficult due to persistent challenges with sensitivity, analyte specificity, accuracy, calibration stability, and biological interference.

Besides the technical program, which encompasses plenary talks, poster sessions, short courses, and many contributed oral presentations, SciX also has several social events for attendees to enjoy in the evenings during the conference week. We highlight these social events here.
