Is the NH4+-induced growth inhibition caused by the NH4+ form of the nitrogen source or by soil acidification? [PDF]
Soil acidification often occurs when the concentration of ammonium (NH4+) in soil rises, such as that observed in farmland. Both soil acidification and excess NH4+ have serious adverse effects on crop growth and food production.

α‐Synuclein Forms Distinct Micelle‐Like Assemblies at Low Ionic Strengths
At high ionic strength, α‐synuclein forms diverse assemblies, including oligomers, fibrils, and condensates. Here, we show that at low ionic strength, α‐synuclein adopts a distinct, low‐abundance assembly state. These assemblies maintain a constant size above a critical concentration and do not coalesce, suggesting a micelle‐like organization ...

Constrained Forest Methane Sink by Thermal Adaptation of Soil Methanotrophs
Climate warming can stimulate methanotroph‐mediated CH4 oxidation in forest soils, thereby mitigating the increase in atmospheric CH4 concentrations. By integrating evidence from a macro‐climatic thermal gradient and a 70‐day incubation experiment, this study demonstrates that microbial methanotrophs can adapt to long‐term temperature changes at the ...

A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.

The initial kinetics of NH3/NH4+ efflux from L3Teladorsagia circumcincta
The initial rate of NH3/NH4+ accumulation in a medium containing L3Teladorsagia circumcincta was 0.18–0.6 pmol h− 1 larva− 1, which increased linearly with larval density.

Interfacial tandem catalysis is developed for efficient electrochemical reduction of NO3− to NH3 over a CuSn(OH)6/Co heterostructure. CuSn(OH)6 accelerates the rate‐determining NO3−‐to‐*NO2 conversion, whereas Co promotes H2O dissociation to enhance *H supply for the rapid hydrogenation of *NO2 intermediate to NH3.

Regulation of Apoplastic NH4 +Concentration in Leaves of Oilseed Rape
Regulation of apoplastic NH4 + concentration in leaves of oilseed rape (Brassica napus L.) was studied using a vacuum-infiltration technique that allowed controlled manipulations of the apoplastic solution.
