Higher‐Level Structural Classification of Pseudomonas Cyclic Lipopeptides through Their Bioactive Conformation

open access: yesAdvanced Science, EarlyView.
Solution structures of a series of cyclic lipodepsipeptides from Pseudomonas reveal that these specialized metabolites adopt left‐handed alpha helical conformations of only two types, being either ‘stapled’ or ‘catch‐pole’ helix. The particular modular distribution of the biosynthetic gene clusters is found to determine the extent of their conserved ...

Decoding Proton‐Coupled Electron Transfer Mechanism of Nicotine for Multi‐Scenario Portable Electrochemical Sensing

open access: yesAdvanced Science, EarlyView.
A key challenge in nicotine electroanalysis is the unresolved complexity of its interface process, which directly determines sensor metrics. Herein, the proton‐coupled electron transfer mechanism of nicotine is decoded for multi‐scenario portable electrochemical sensing.

A Scoping Review of Nudges for Enhancing Agricultural Policy

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Following PRISMA guidelines, we conduct a scoping review on 18 empirical studies on nudging interventions for farmers in Europe and the USA. The evidence on the effectiveness of nudges is mixed. Some studies demonstrate positive outcomes, particularly when nudges are combined with other interventions; others report no effect or negative ...
