A new fluorescent sensor could make antibiotic detection much faster and more affordable. The post Glowing probe detects multiple antibiotics with just a smartphone appeared first on Advanced Science News .

Idea While reproducing top solutions of a chemistry data competition , I started building a DuckDB community extension for handling chemistry data directly in SQL. What it can do Parse SMILES, InChI, PDB and other chemistry formats directly — no pandas, no RDKit on the side Plug into DuckDB's native CSV/Parquet/Iceberg/S3/HTTP readers, so ingestion + light preprocessing happens in one query Backg…

Laramie Jensen’s interest in inorganic and analytical chemistry led her to the ocean. And then to the North Pole.

Researchers have developed a fast, practical test to evaluate quality of black coffee, offering baristas and scientists a clearer window into flavor without complex lab work. The post Scientists Develop Quicker Test to Measure Coffee Quality appeared first on Sci.News: Breaking Science News .

New research from Professor Anna Slater and colleagues at the University of Liverpool demonstrates how continuous flow chemistry, combined with inline UV-Vis spectroscopy, can transform both the understanding and execution of porphyrin synthesis leading to improved yields in both quality and quantity.

What submitting to Chemical Science actually requires: Andrew Cooper's editorial process, the diamond open-access model (no APC for authors or readers, since 2015), the Edge Article format with no hard page limit, the 33-day median decision time, and the 60-70% desk-rejection rate.

A new doctoral thesis at Karlstad University provides increased understanding of how medicines can be analysed more reliably and safely.

Shimadzu Corporation has acquired a 75% stake of the outstanding shares of German startup Plasmion GmbH (headquartered in Augsburg, Bavaria) on March 23, making the company a subsidiary. This acquisition aims to obtain Plasmion’s mass spectrometer (MS) ion source technology SICRIT（Soft Ionization by...

Nature Communications, Published online: 28 April 2026; doi:10.1038/s41467-026-72342-7 Infections caused by multi-drug resistant bacteria present a global health challenge, so the identification of bacterial species is essential to avoid the unnecessary use of antibiotics and to minimize the emergence of additional resistance. Here, the authors present a lifetime cross-reactive sensor array that …
