Transient Ecological Niches for Diazotrophs in Upwelling Bays

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18

Rational Design, Synthesis, and Biological Evaluation of New Substituted Dihydropyrimidinones as Antibacterial Agents and β‐Lactamase Inhibitors

open access: yesChemical Biology &Drug Design, Volume 108, Issue 2, August 2026.
Novel 1,6‐dihydropyrimidinones act as antibacterial agents and beta‐lactamase inhibitors. Compounds 3d, 3i, and 7b demonstrated enhanced beta‐lactamase inhibition relative to the standard reference, clavulanic acid, demonstrating significant potentiation effects to restore antibiotic efficacy and combat resistant bacterial strains.

Physiology and Transcriptomics Reveal Divergent Strategies of Mycorrhiza‐Mediated Drought Adaptation in Poplar

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5078-5094, August 2026.
ABSTRACT Mycorrhizal symbiosis shapes plant growth and stress resilience. Here, we compared physiological and molecular responses of poplars (P. x canescens) colonised by Paxillus involutus (Pi) or Cenococcum geophilum (Cg) under control conditions, drought stress and recovery.

Metal–Drug Complexes as Long‐Release Application for Antimalarial PfFNT‐Inhibitors

open access: yesChemMedChem, Volume 21, Issue 13, 14 July 2026.
P. falciparum formate‐nitrite transporter (PfFNT) inhibitors have emerged as a novel antimalarial class with potent in vivo and liver‐stage activity. Low‐solubility metal–inhibitor complexes were prepared as potential long‐acting injectables.

Fluorinated Aminopiperidones as Non‐Glutarimide Thalidomide Analogs: Stereodivergent Synthesis and Validation

open access: yesChemMedChem, Volume 21, Issue 13, 14 July 2026.
Fluorinated aminopiperidones, designed as non‐glutarimide thalidomide analogs, were synthesized with full regio‐ and stereocontrol. The C*–CF3 used as carbonyl surrogate improved solubility and membrane interactions while abolishing cereblon binding.

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

open access: yesAdvanced Science, Volume 13, Issue 39, 13 July 2026.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Poisoning by Acetanilid. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1896
Quincy, Ill, Jan. 19, 1896. To the Editor: —In ourJournalof Jan. 18, 1896, page 144, reference is made to a report in the Virginia Medical Monthly , by Dr. Ben. H. Broadnax, on the use of acetanilid. Having recently had in my own practice two cases of acetanilid poisoning, one terminating fatally, I can not, therefore, indorse Dr.

Influence of substrate freshness on metabolite dynamics and methane emissions from pig slurry during laboratory incubation

open access: yesJournal of Environmental Quality, Volume 55, Issue 4, July/August 2026.
Abstract Freeze/thaw pretreatment is commonly applied to animal slurry samples in laboratory studies, but its impact on organic matter transformation and methane (CH4) emissions remains uncertain. In this study, slurry incubations were performed at 20°C with three treatments differing in freshness of feces, urine, and inoculum.

Investigations on the Role of Support and Synthesis Procedure for the Rux–Cuy/CNT‐Catalysed Hydrogenolysis of Glycerol to 1,2‐Propanediol

open access: yesChemistryOpen, Volume 15, Issue 7, July 2026.
Sophisticated carbon supports like single‐ and multiwall carbon nanotubes as well as Globugraphite were used for the synthesis of bimetallic Ru–Cu catalysts, which were tested in a multi batch reactor setup for the chemical hydrogenolysis of glycerol to 1,2‐propanediol (1,2‐PDO) at 220 °C under 30 bar of hydrogen pressure in aqueous solution.
