Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

open access: yesEcological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Efficacy of Zeolite and Kaolin in the Control of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) and Compatibility With Its Natural Antagonist Anthocoris nemoralis (Fabricius) (Hemiptera: Anthocoridae)

open access: yesJournal of Applied Entomology, Volume 150, Issue 8, Page 1080-1087, September 2026.
ABSTRACT The pear psyllid Cacopsylla pyri is a major pest of European pear orchards, responsible for significant yield losses. Its management is increasingly challenged by restrictions on synthetic active ingredients, resistance development, and the shift towards sustainable production systems.

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2799-2817, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Structure‐Guided Engineering of a Ser192Ala Variant Enhances Bidirectional Catalysis in Amycolatopsis sulphurea L‐Alanine Dehydrogenase

open access: yesChemCatChem, Volume 18, Issue 15, 14 August 2026.
A rationally engineered Ser192Ala variant of Amycolatopsis sulphurea L‐alanine dehydrogenase (L‐AlaDH) exhibits ∼2‐fold higher catalytic efficiency in both reductive amination and oxidative deamination. Experimental characterization confirms maintained stability under tested conditions, highlighting its potential as an improved biocatalyst for ...

Cordyceps militaris Ethanol Extract Alleviates Hyperglycemia in Type 2 Diabetic Mice in Association With Gut Microbiota Modification

open access: yeseFood, Volume 7, Issue 4, August 2026.
Cordyceps militaris ethanol extract (CME) shows potential for ameliorating glucose and lipid metabolism in T2DM mice. The improvements are correlated with the regulation of gut microbiota and increased short‐chain fatty acid levels, offering a novel perspective for future diabetes interventions.

Mycoplasma bovis involved in pituitary abscess syndrome in a beef heifer concomitantly infected with haemoparasites

open access: yesVeterinary Record Case Reports, Volume 14, Issue 3, August 2026.
Abstract This case report describes pituitary abscess syndrome (PAS) in a 20‐month‐old Blonde d'Aquitaine heifer with cranial nerve deficits (V, VII, VIII, IX, X and XII) associated with facial hemiparesis, head tilt, ataxia and dysphagia, pneumonia and otitis interna.

Transient Ecological Niches for Diazotrophs in Upwelling Bays

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18
