Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

open access: yesPest Management Science, Volume 82, Issue 7, Page 5987-6009, July 2026.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Scaffold Dependent Coordination Modes of Chelating PEP‐Type Ligands in Iron(0) Carbonyl Complexes (E = O, S)

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.
The reaction of iron pentacarbonyl with various chelating diphosphine ligands containing oxygen or sulfur atoms in their backbone yields complexes that exhibit noteworthy coordination behavior. Depending on the natural bite angle of the ligands and the coordination behavior of the heteroatom, preferences regarding the coordination geometry are verified

Electrical Stimulation Directs Formation of Perfused Vasculature in Engineered Tissues

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
Electrical stimulation (ESTIM) enhances vasculature formation in engineered human tissues. In 3D endothelial‐fibroblast constructs, conditioning with ESTIM promotes the formation of dense and highly branched networks that rapidly anastomose with mouse vasculature when implanted in vivo. Vessels formed under ESTIM are importantly functionally perfusable.
