Auxin and Cytokinin Differentially Regulate Growth, Bud initiation, and Leaf Morphology in the Dryland Moss Syntrichia caninervis Brid

This study demonstrates that while auxin and cytokinin exhibit partially conserved, antagonistic roles in regulating growth and development in the dryland moss *Syntrichia caninervis*, species-specific hormonal sensitivities offer promising strategies for biocrust restoration in dryland ecosystems.

Identification and applicability of azg1 as counter-selectable marker in Trichoderma species

This study establishes the endogenous gene *azg1* as a versatile counter-selectable marker and expands the genetic toolkit for *Trichoderma* species by enabling efficient targeted integration and engineering through CRISPR/Cas9-mediated disruption of 8-azaguanine uptake and heterologous sensitization to 5-fluorocytosine.

MiR-204-5p signalling modulates apoptosis and mitophagy-related changes after intracerebral hemorrhage in adult rats

This study demonstrates that in a rat model of intracerebral hemorrhage, the downregulation of miR-204-5p contributes to neuronal injury by disrupting the GATA3–miR-204-5p–CAMK1/TAOK1 axis, leading to increased apoptosis and mitophagy disturbances, which can be mitigated by miR-204-5p overexpression or donepezil pretreatment.

The Ectodermal-Brain Memory to Explain the Methylation Pattern of the ASD Gene Matrix

This study utilizes buccal swabs as a proxy for ectodermal brain memory to identify distinct DNA methylation patterns in Autism Spectrum Disorder (ASD), revealing thousands of differentially methylated regions and novel candidate genes that overlap with known SFARI autism-associated genes, thereby supporting an epigenetic, embryonic-origin model for the disorder.

In vitro inhibitory assessment of Lactobacillus spp. supernatant on the growth of Candida glabrata and Cryptococcus neoformans yeasts.

This study demonstrates that cell-free supernatants from *Lactobacillus* spp., particularly *L. reuteri*, effectively inhibit the growth of pathogenic yeasts *Candida glabrata* and *Cryptococcus neoformans* through organic acid production, suggesting their potential as safe and cost-effective adjuncts to conventional antifungal therapies.

Early-stage heterotrophy and feeding effects on growth and survival of sexually produced elkhorn coral (Acropora palmata) spats

A two-week ex situ experiment on sexually produced elkhorn coral (Acropora palmata) spats from the Dominican Republic demonstrates that while short-term survival remains high regardless of diet, heterotrophic feeding—particularly with freshly hatched Artemia—significantly enhances early post-settlement growth, suggesting that active zooplanktivory can be leveraged to improve coral restoration outcomes.

Large-Scale Mutagenesis Identifies Sequence Changes That Bias Tau Toward CTE-like Aggregation

By combining computational mutagenesis with experimental validation, this study identifies specific sequence changes in the tau protein that bias its aggregation toward chronic traumatic encephalopathy (CTE)-like structures rather than Alzheimer's disease folds, thereby establishing a framework for defining sequence–structure relationships in polymorphic amyloids.

Altered prefrontal late positive potential responses during neutral face processing are associated with negative interpretation bias in major depressive disorder

This study demonstrates that individuals with major depressive disorder exhibit altered prefrontal late positive potential responses during neutral face processing, which are significantly associated with negative interpretation bias and indirectly linked to reduced social competence.
