Increased arbuscular mycorrhizal fungal biomass and diversity in soil under long‐term climate drying and warming

open access: yesNew Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) support critical ecosystem services including plant resource acquisition and productivity. AMF functional traits such as relative biomass investment in root vs soil colonization or drought tolerance are thought to be evolutionarily conserved within AMF lineages and might influence AMF community responses to ...

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...

Synthesis, characterization, and performance of x_MoO3/Z‐22 and x_MoO3/MMP catalysts for biodiesel production

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2820-2841, June 2026.
Methyl transesterification of soybean oil using heterogeneous catalysts for biodiesel production. Abstract The growing global demand for renewable fuels has driven the search for efficient catalysts in biodiesel production. This study presents the synthesis and characterization of x_MoO3/Z‐22 and x_MoO3/MMP heterogeneous catalysts, and evaluates the ...

Multiparasitism Resolves the Apparent Paradox of High Male Pheromone Investment Despite Frequent Within‐Host Mating in a Parasitoid

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 579-588, June 2026.
It is unknown why males of the parasitoid wasp Nasonia giraulti produce large amounts of a costly sex pheromone although they were long thought to mate with their females already before emergence within the host. Mated females do no longer respond to the pheromone.

Sustainable Syntheses of p‐Hydroxycinnamic‐Based Macrobisphenols: Progress, Challenges, and Comparative Assessment of Yield and Sustainability

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
The strengths and limitations of sustainable routes to macrobisphenols — safe‐by‐design biomass‐derived bisphenols — were critically evaluated to support informed selection based on sustainability metrics (EcoScale, E‐factor), efficiency, cost, and scalability.

Investigation of Covalent Adaptable Networks (CANs) Based on Dynamic Acylhydrazone Bonds Featuring Shape‐Memory Ability

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 18, May 10, 2026.
Application of dynamic acylhydrazones to achieve CANs with shape‐memory properties. ABSTRACT Covalent adaptable networks (CANs) are based on reversible crosslinks, which are present within the polymer network structure. Due to these reversible moieties, CANs feature interesting properties/abilities such as self‐healing after damage, shape‐memory ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, Volume 600, Issue 9, Page 1265-1287, May 2026.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
