Evaluation of rheological and fluid loss properties of Nigerian bentonite using periwinkle and mucuna solannie

open access: yesCogent Engineering, 2021
Nigerian bentonite has low fluid loss control and poor rheological properties which are key API specifications. Foreign and imported bentonites are sodium-based, while local bentonites are calcium-based, and there is a need for beneficiation.

Limited capacity for rapid acclimation to marine heatwaves in coastal invertebrates

open access: yesJournal of Animal Ecology, Volume 95, Issue 10, Page 2088-2103, October 2026.
Across 10 coastal invertebrate species, we provide a rare multi‐species test of rapid acclimation to realistic marine heatwaves. Responses are consistently weak, revealing that short‐term plasticity cannot keep pace with warming and may lead to underestimated vulnerability in coastal ecosystems. Abstract Marine heatwaves are increasing in frequency and

Network indices show heat wave‐induced fragility in experimental food webs: Operational insights for ecosystem management

open access: yesEcological Applications, Volume 36, Issue 6, September 2026.
Abstract Emerging global change imposes challenges for marine ecosystems placing them at the verge of collapse. The identification of early signs of ecosystem collapse is crucial to assist adaptive management. Shifts in the ecosystems are preceded by rewiring of ecological networks.

Systematic prioritization of candidate genes in camptothecin biosynthesis using multi‐omics and deep learning

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Camptothecin (CPT), a plant‐derived monoterpene indole alkaloid first identified in Camptotheca acuminata, is a drug precursor widely used for cancer chemotherapeutics. However, the full set of genes responsible for CPT biosynthesis remains unclear, hindering efforts to elucidate the complete pathway or establish biosynthetic production of CPT
