Enhancing Ground Beef Shelf Life Using Psidium guajava Leaf and Oliveria decumbens Essential Oils: Antimicrobial, Antioxidant, and Quality Preservation Effects Under Refrigeration

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Guava leaf essential oil (GL‐EO) and Oliveria decumbens essential oil (Od‐EO) improved the microbial and oxidative stability of refrigerated ground beef and helped extend its shelf life. GL‐EO better preserved odor and color, while the combined GL‐EO + Od‐EO treatment provided the best texture preservation and highest overall acceptability.

Harvest Stage‐Dependent Variation in Essential Oil Chemotype and Agronomic Yield of Parsley (Petroselinum crispum (Mill.) Fuss)

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Parsley (Petroselinum crispum) was harvested at four ontogenetic stages (Pet‐1 to Pet‐4; May–September) under Mediterranean field conditions. Harvest timing significantly affected both agronomic yield and essential oil (EO) composition. Biomass yield peaked at Pet‐4 (10,076 kg da−1); EO content was highest at Pet‐2 (0.70%). GC–MS identified 55 volatile

Applications and limitations of AI tools in enzyme design

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Enzymes catalyze various different chemical reactions often with high efficiency and selectivity compared to synthetic catalysts. Advances in protein engineering over the past decades have allowed researchers to design enzymes, improving their catalytic performance and adapting them for specific or entirely novel chemical reactions.

RCSB protein data Bank: Next‐generation advanced search for exploration of experimental structures and computed structure models

Protein Science, Volume 35, Issue 8, August 2026.
Abstract The Protein Data Bank (PDB), established in 1971, is the primary global, open‐access archive for experimentally determined 3D macromolecular structures (proteins, RNA, DNA). The research‐focused RCSB.org web‐portal provides access to these data alongside more than one million machine‐learning‐predicted structure models, greatly expanding the ...

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

Pest Management Science, Volume 82, Issue 8, Page 7510-7525, August 2026.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Chemical Profile and Antibacterial Activity of Cymbopogon Citratus Leaf Essential Oil

ChemistrySelect, Volume 11, Issue 29, 3 August 2026.
The essential oil of Cymbopogon citratus was chemically characterized by GC–MS and evaluated for antibacterial activity against clinically relevant Gram‐positive and Gram‐negative bacteria. Citral isomers (geranial and neral) were identified as the major constituents, and the oil exhibited selective bactericidal and bacteriostatic effects, supporting ...

Structural basis for a p21‐activated kinase 4 and nicotinamide phosphoribosyltransferase dual inhibitor

Acta Crystallographica Section D, Volume 82, Issue 8, Page 972-981, August 2026.
The 2‐aminopyridine moiety of KPT‐7523 binds p21‐activated kinase 4 and nicotinamide phosphoribosyltransferase, enabling a versatile design for multi‐target cancer therapy.Simultaneous inhibition of oncogenic signaling and metabolic pathways represents a promising approach for cancer therapy.

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, Volume 24, Issue 8, Page 4823-4843, August 2026.
ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

Transcriptome and Hormone Regulations Shape Drought Stress‐Dependent Fusarium Head Blight Susceptibility in Different Barley Genotypes

Plant, Cell &Environment, Volume 49, Issue 8, Page 5738-5755, August 2026.
ABSTRACT Little is known about regulatory mechanisms that crop plants use to respond to combinations of abiotic and biotic stress. We analysed four barley genotypes under simultaneous Fusarium culmorum infection and drought stress by phenotyping for Fusarium Head Blight (FHB) disease, drought stress responses, hormone profiling and transcriptome ...

Organ‐specific terpenoid responses in Tanacetum vulgare are chemotype‐dependent

Plant Biology, Volume 28, Issue 5, Page 1437-1453, August 2026.
Common tansy varieties defend differently: some boost root chemicals against soil pests, while others release stronger leaf scents against aphids. Abstract Specialized metabolites such as terpenoids are known to mediate plant defence mechanisms. However, how terpenoid diversity governs inducible chemistry across organs remains poorly understood.
