Epitranscriptomic regulation of antimony resistance in Leishmania via m6A RNA modification

This study demonstrates that dynamic, reversible N6-methyladenosine (m6A) RNA modifications serve as a rapid post-transcriptional switch regulating antimony resistance genes in *Leishmania infantum*, exhibiting a dose-dependent "epitranscriptomic memory" that correlates methylation changes with gene expression levels to drive drug resistance.

Robust Group Effects Without Reliable Individual Differences: Space–Time Interference and Magnitude Perception in Children

This study reveals that while group-level space–time interference effects are robust in children, the individual difference scores used to measure these effects are statistically unreliable, rendering previous claims about developmental changes or correlations with cognitive capacity uninterpretable.

Metacommunities of water bugs are driven by environmental, spatial, and landscape factors in Cerrado freshwater habitats along a land-use gradient

This study demonstrates that the assembly of water bug communities (Nepomorpha and Gerromorpha) in Cerrado freshwater habitats is driven by a complex interplay of environmental, landscape, and spatial factors, with the relative importance of these drivers varying significantly between lentic and lotic habitats and between the two taxonomic groups.

Fhl2 identifies a Hedgehog-dependent myofibre population along the zebrafish midline with high regenerative potential and enhanced resilience in dystrophy

This study identifies a previously unrecognized population of medial slow myofibres in zebrafish, marked by Fhl2 expression and dependent on Hedgehog signaling, which exhibit unique molecular characteristics and demonstrate exceptional resilience and regenerative capacity in muscular dystrophy.

Expanding the flavonoid production in Acinetobacter baylyi ADP1 from lignin-derived aromatics

This study establishes *Acinetobacter baylyi* ADP1 as a versatile microbial platform capable of efficiently converting diverse lignin-derived aromatics into multiple flavonoids using a novel enzyme combination, enabling sustainable production directly from complex industrial lignin streams without the need for extensive genetic re-engineering.

Viability-Dependent and Structural Modulation of IL-10 Secretion in THP-1 Cells by Lactobacillus gasseri and Lacticaseibacillus rhamnosus

This study demonstrates that while structural components of *Lactobacillus gasseri* and *Lacticaseibacillus rhamnosus* are sufficient to induce IL-10 secretion in THP-1 cells, live bacterial preparations elicit a significantly more robust and rapid transcriptional response, highlighting the critical role of viability in amplifying anti-inflammatory modulation.

Comparative study of nucleus accumbens shell and core lesions in relation to body weight in healthy and activity-based anorexia female Wistar rats

This study investigated the differential effects of nucleus accumbens shell versus core lesions on body weight in healthy and activity-based anorexia female Wistar rats, finding distinct but statistically non-significant post-lesion weight trajectories that suggest a need for sham-controlled, histologically verified future research to clarify the subregions' roles in weight regulation.
