Achillea millefolium L. is a medicinal plant widely harvested for traditional and official use across the Balkan region, yet its elemental composition and safety profile remain uncharacterized for Albanian localities. This study evaluated the concentrations of macro elements (N, P, K, Ca, Mg) and microelements (Fe, Zn, Mn, Cd) in the aerial parts of A. millefolium collected from five regions of A…

Post-harvest sorting of potatoes is a key step in ensuring quality, preventing degradation of stored stocks and reducing subsequent losses. Traditional manual sorting methods are laborious, subjective and inconsistent, especially in large operations. This study presents an approach to potato detection and classification using the YOLOv11 “You only look once” architecture. The application is in a …

BackgroundGelsemium elegans (Gardner and Champ.) Benth. (Gelsemiaceae), commonly known as heartbreak grass, is a popular herb to treat a variety of ailments, native to China and Southeast Asia. Its toxicity is attributed to the indole alkaloid it contains, particularly koumine.MethodsIn this research, the iterative factor was integrated into a validated high-performance thin-layer chromatography …

Nature Communications, Published online: 19 May 2026; doi:10.1038/s41467-026-73175-0 Chemical warfare agents (CWAs) are highly toxic compounds capable of causing mass casualties on the battlefield. Current analytical methods for detecting blister, nerve, and blood agents suffer from several inherent limitations, including false-positive results, high costs, susceptibility to environmental interfe…

Nature Communications, Published online: 18 May 2026; doi:10.1038/s41467-026-73272-0 Photo-cross-linking is widely used in protein science, but site-specific identification remains elusive. Here, the authors show that alkyl diazirine cross-links are inherently MS-cleavable and develop an analytical framework that integrates seamlessly with existing search platforms.
