Cancer pattern in Bhutan (2014–2022): Findings from population‐based cancer registry—A pathway to monitor cancer control activities

International Journal of Cancer, Volume 158, Issue 11, Page 2829-2840, 1 June 2026.
What's new? The establishment in 2014 of the population‐based cancer registry (PBCR) of Bhutan created new opportunities for understanding national cancer trends, which previously were anticipated from data in neighbouring countries. This study presents the first nine‐year summary of cancer patterns in Bhutan, derived from PBCR data. From 2014 to 2022,

The Evolution of Electrochemical and Safety Properties of Nonflammable Triethyl Phosphate Based Electrolyte Under Salt Concentration Control

Safety Science and Technology, Volume 1, Issue 2, June 2026.
By regulating the lithium salt concentration to alter the solvation structure of Li+, and subsequently affecting the chemical composition of the SEI, the evolution of salt concentration on the electrochemical and safety performance of cells are explored. ABSTRACT Phosphates exhibit excellent flame retardancy. Phosphate‐based electrolytes with high‐salt‐

Wheat's war against stripe rust: Integrating host immunity, genomics and breeding for durable resistance

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.
