Experimental Evidence for a Metal‐Related Function of a Cyanobactin

open access: yesAngewandte Chemie International Edition, EarlyView.
Cyanobactins such as patellamides are produced by cyanobacteria profusely and have been studied extensively, but almost exclusively for their cytotoxic properties. Discussed is unprecedented experimental evidence for a metal‐related biological function – likely CO2 transport from the ascidian to the cyanobacterial symbiont.

Production Country Origin Impact on Soybean Oil Quality

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Previous studies have suggested variability in soybean oil quality depending on geographic origin of the soybeans. In this study, 1035 crude degummed soybean oil (raw oil unrefined except for degumming) samples collected from vessels and crushers over five harvest years (2020–2024) were analyzed for 11 key quality attributes.

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.
