Soil Microbiota and Rhizosphere Dynamics: Ecological Mechanisms Driving Crop Stress Adaptation in Climate‐Smart Agriculture

open access: yesFood and Energy Security, Volume 15, Issue 4, July/August 2026.
ABSTRACT Climate change‐mediated abiotic stresses limit crop performance, and plant responses are increasingly recognized as emergent properties of the coupling between soil, plants, and microbiomes rather than inherent plant characteristics. This review synthesizes mechanistic evidence from 2020 to 2025 on how rhizosphere microbiota contribute to crop

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

open access: yesJournal of Surfactants and Detergents, Volume 29, Issue 4, Page 537-547, July 2026.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Management of invasive alien plants in forests: A global perspective

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
This review exposes urgent and critical knowledge gaps in forest IAP management, which need addressing to meet global targets for biodiversity and forest health. These gaps include highly uneven global research effort, narrow species focus, limited method replication, overlooked seasonal effects, and inconsistent cost reporting.

Chemogenetic Stimulation of the Dorsal Motor Nucleus of the Vagus Mitigates Autonomic Dysfunction and Memory Decline in Rat Model of Alzheimer‐Like Disease

open access: yesActa Physiologica, Volume 242, Issue 7, July 2026.
ABSTRACT Aim To test the hypothesis that Alzheimer‐like metabolic neurodegeneration rat model leads to an autonomic dysfunction, memory impairment, and hippocampal amyloid pathology and that long‐term chemogenetic stimulation of the dorsal motor nucleus of the vagus reverses these alterations. Methods Male and female transgenic Long Evans rats received
