Bacterial Cyclodipeptides Target Signal Pathways Involved in Malignant Melanoma

open access: yesFrontiers in Oncology, 2020
Melanoma is an aggressive cancer that utilizes multiple signaling pathways, including those that involve oncogenes, proto-oncogenes, and tumor suppressors. It has been suggested that melanoma formation requires cross-talk of the PI3K/Akt/mTOR and Ras-ERK

Artificial exposure to herbivore‐induced volatile organic compounds reduces herbivory and modulates gene expression in potato plants

open access: yesJournal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings provide strong mechanistic evidence for VOCs mediating pest resistance and suggest that exposure to herbivore‐induced, plant‐derived VOCs can enhance pest resistance in potato crops. These results might offer novel information for developing ecologically sustainable plant volatile‐based strategies for boosting protection against pests in

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.

Pretreatment Effects of Conventional and Reactive Extrusion on LLDPE Waste Pyrolysis

open access: yesPolymer Engineering &Science, Volume 66, Issue 7, Page 5191-5199, July 2026.
Schematic overview of the pyrolysis study using original and pretreated LLDPE waste samples. Pretreatment was performed via twin‐screw extrusion at 450°C: without additives (REX), with peroxide (REX‐RO2), or with polypropylene (REX–PP). All four samples underwent pyrolysis at 450°C–475°C for 15–45 min.

Triiodide Faujasites With Reactive, Ionic, Antimicrobial, and Catalytic Applications

open access: yesSmall Structures, Volume 7, Issue 7, July 2026.
Alkyl iodides and zeolites react under open‐air reaction conditions to give triiodide anions (I3−) inside the zeolite (I3−@zeolite), without any additive or solvent. The multigram solid, with up to ≈25 wt% I3− loadings, is active as a water disinfection agent, bacteria and yeast antiseptic, solid electrolyte, and catalytic solid for the carbonyl–olefin
