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.



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.


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.

In the final part of our conversation with Leonardos “Leo” Gkouvelis, we discussed what happens when opposition effects are ignored when studying exoplanets and how it impacts our understanding of their surface composition.

A new review article published in Applied Spectroscopy Reviews highlights how visible–near infrared (Vis-NIR) spectroscopy could improve the way scientists detect and monitor potentially toxic trace elements (PTEs) in soil and sediments.

A recent study proposed and tested a new approach for monitoring the nutritional quality of orange juice.

Top articles published this week include a video interview discussing the opposition surge effect in astronomy, a peer-reviewed article about charge transfer complexes in antibiotics, and a news article about using reflectance spectroscopy to analyze soil in the Amazon.


In a continuation of our conversation with Leonardos “Leo” Gkouvelis, who is in the Faculty of Physics at Ludwig Maximilian University (Munich, Germany), we discussed the phenomenon of shadow hiding and coherent back scattering in astronomy, particularly in the context of observing celestial bodies like the moon and exoplanets.

Recently, a team of researchers examined how to improve camouflage technology for defense applications by integrating spatial and spectral dimensions across optical, thermal infrared, terahertz, and microwave bands.

In this interview segment, Leo Gkouvelis of Ludwig Maximilian University discusses the opposition surge effect and how his study explored a new method for modeling the opposition surge effect in studying exoplanets.

As part of the SciX Conference program, a keynote presentation is set to take place on Monday October 6, 2025, from 8:30–9:30 am EST in Ballroom B. This year’s keynote speaker is Michael Gold of Redwire, and he will deliver a talk titled, “Unveiling the Unknown: The Pursuit to Understand UAP’s."


This year, the SciX Conference will take place at the Northern Kentucky Convention Center in Covington, Kentucky, from October 5–10, 2025

A recent study provided new information on how berberine mid-chain fatty acid salts interact with lysozyme.


A recent study conducted by researchers from the Taiyuan University of Technology (China) explored a new way to detect pesticide residues at very low levels.

Spectroscopy is being used in speleology more frequently now. In this brief article, we highlight how it is being used and what spectroscopic techniques are being applied.

A recent study investigated the deterioration mechanisms of rammed earth materials from the UNESCO World Heritage Pingyao Ancient City walls.

This explainer video highlights how nuclear magnetic resonance (NMR) spectroscopy is being used to improve the evaluation of vegetable oil quality.


A recent study tested a new mitochondria-targeting fluorescent probe, known as Mito-CDM, to see if it can improve the monitoring of mitochondrial viscosity.

A recent study demonstrated that combining hyperspectral imaging with multivariate curve resolution can non-invasively detect and monitor intestinal necrosis in acute mesenteric ischemia, offering a promising tool for earlier diagnosis and improved patient outcomes.

In Part 2 of this “Inside the Laboratory,” feature on George Shields, a professor of chemistry at Furman University and the founder and director of the Molecular Education and Research Consortium in Undergraduate Computational ChemistRY (MERCURY), Consortium, we discuss his research into computational approaches to improve our understanding of molecular behavior in both biochemistry and atmospheric chemistry and his work applying replica exchange molecular dynamics (REMD) for breast cancer drug design.

Top articles published this week include a video highlighting some of the icons of spectroscopy and a news article about using machine learning to quantify uncertainty in spectroscopic analyses.
