A study published in Scientific Reports has given intricate details into the production and composition of Roman Egyptian blue pigment. Using advanced Raman microspectroscopy, researchers explored pigment balls and murals from ancient Swiss cities, uncovering evidence of raw material provenance, crystal lattice disorder, and the formation of a copper-bearing green glass phase, revealing the sophisticated techniques employed by Roman artisans.

Researchers from Humboldt-Universität in Berlin have utilized ultraviolet resonance Raman (UVRR) spectroscopy to differentiate between bovine serum albumin (BSA) and human serum albumin (HSA) based on their similar structures and amino acid composition. By comparing the UVRR spectra of the proteins with those of specific amino acids, they have identified distinctive features that allow for accurate discrimination and provide insights into the secondary structure and binding sites of serum albumins.

In a pioneering study published in Nature, researchers have presented their findings on the atmospheric properties of the exoplanet WASP-39b. Using data obtained from the JWST NIRISS instrument, the team successfully breaks model degeneracies and reveals intriguing insights into the exoplanet's heavy-element enhancement, carbon-to-oxygen ratio, potassium-to-oxygen ratio, and the presence of wavelength-dependent, non-grey clouds.

A review article explores the significance of analyzing terrestrial analogues to enhance spectroscopic capabilities for Mars exploration. The review highlights key findings and lessons learned from studying terrestrial analogues, providing valuable insights for the development of spectroscopic systems in current and future missions to Mars.

A sample library of selected references discussing the application of artificial intelligence (AI) in analytical chemistry and molecular spectroscopy is presented.

We interviewed an AI program (ChatGPT) for Spectroscopy asking questions about AI and its role in various applications for vibrational and atomic spectroscopy, including data analysis.
