Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

open access: yesiMetaOmics, Volume 3, Issue 3, September 2026.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Effects of pyrroloquinoline quinone and imidazole pyrroloquinoline on biological activities and neural functions

open access: yesHeliyon, 2020
Pyrroloquinoline quinone (PQQ) is contained in fruits and vegetables and in human breast milk. It has been reported that PQQ has high reactivity and changes to an imidazole structure (imidazole pyrroloquinoline) by a reaction with an amino acid at a high

Bacillus subtilis Mobilizes Phosphorus by Reshaping P Pools, Sorption, and Enzyme Activities

open access: yesLand Degradation &Development, Volume 37, Issue 15, Page 10882-10892, September 2026.
ABSTRACT Low phosphorus (P) availability constrains crop production in saline‐alkaline soils of Xinjiang, China. We tested whether Bacillus subtilis ( B. subtilis ) mobilizes soil P by altering P fractions, sorption–desorption, and P‐cycling enzymes in a saline‐alkaline cotton soil. Under conventional fertilization, B.

Compartment‐Specific Functional and Taxonomic Responses of Plant Growth‐Promoting Microbiomes Following Oxytetracycline Trunk Injection in Citrus

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus, is the most destructive disease affecting citrus production worldwide. Trunk injection of oxytetracycline (OTC) is increasingly used to suppress the pathogen and improve tree performance, yet its ecological consequences for plant‐associated microbiomes remain poorly understood ...

A Mechanism‐Based Framework for Anti‐Aging Strategies: From Metabolic Regulation to Senotherapy and Stem Cell‐Based Interventions

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
The aging of the human body is a complex process driven by multiple contributing factors. Based on their underlying mechanisms, current anti‐aging interventions can be classified into six primary categories. This paper summarizes the most promising anti‐aging strategies within each class. ABSTRACT The global prevalence of aging and age‐related diseases

Effects of a Dietary Supplement on Systemic Aging Related Biomarkers and Skin Aging Outcomes in Middle‐Aged Women: In Vitro and Clinical Studies

open access: yesJournal of Cosmetic Dermatology, Volume 25, Issue 9, September 2026.
ABSTRACT Background Interest in dietary supplements targeting both skin and biological aging biomarkers is rapidly growing, yet existing studies lack rigorous clinical validation of combined oral–topical regimens and concurrent assessment of skin and systemic biomarkers.

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

open access: yesEFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

Substrate‐Affinitive P‐Type Azapolycyclic Photosensitizer for Chemoselective Nitrilization Under Mild Conditions

open access: yesAdvanced Science, Volume 13, Issue 36, 29 June 2026.
We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...
