Nanocomposite Reduces Volatile and Aqueous Reactive Nitrogen Losses From Soil Compared to Conventional and Alternative Fertilisers

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Reactive nitrogen losses from agriculture contribute substantially to greenhouse gas emissions, water pollution and ecosystem degradation. Controlled‐release fertiliser technologies offer potential solutions, yet few comprehensively evaluate performance across multiple nitrogen loss pathways and soil types.

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

New Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.

Virtual Screening of Phytochemicals From Medicinal Plants as Promising PDE5 Inhibitors Against Erectile Dysfunction

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
Phytochemicals from Algerian medicinal plants were virtually screened as potential phosphodiesterase‐5 (PDE5) inhibitors for erectile dysfunction therapy. Drug‐likeness and toxicity analyses identified catechin, ellagic acid, and rosmarinic acid as safe, bioavailable candidates.

Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 132-141, February 2026.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

From Local Biodiversity to Global Food Security: Antioxidant Evidence of Unconventional Edible Plants (2020–2025)

Journal of Food Process Engineering, Volume 49, Issue 2, February 2026.
This scoping review (2020–2025) compiles validated evidence on the antioxidant potential of unconventional edible plants (PANCs). Thirty species showed high phenolic content and strong radical‐scavenging activity, reinforcing their role as natural antioxidants and sustainable alternatives to synthetic additives within biodiversity‐based food systems ...
