Heritability of Productive, Reproductive and Carcass Traits in Pure‐Bred and Cross‐Bred Pigs: A Systematic Review and Meta‐Analysis

ABSTRACT Heritability ( h 2 ) is a key parameter in animal breeding, but its magnitude and consistency across pure‐bred (PB) and cross‐bred (CB) pig populations remain poorly understood. This study aimed to compare heritability estimates between PB and CB populations for economic...

Tracing source and paleoweathering conditions of the lower jurassic sandstone from sierra de santa rosa section, Northern Sonora, México

The Lower Jurassic sedimentary rocks of the Sierra de Santa Rosa Formation in northern Sonora, Mexico has been deposited in a forearc basin and its age has been assigned based on the fossil assemblages and detrital zircon U–Pb geochronology data. Neverthless, their geochemical ch...

The state of diversity, equity, and inclusion in the cloud physics community

The Geosciences are amongst the least diverse research fields, where women and other underrepresented groups face systemic biases. This paper presents the state of diversity, equity, and inclusion (DEI) in the cloud-physics community, by combining a metadata analysis of 6987 clou...

Isolation and Characterization of Lytic Bacteriophages Targeting Clinical Staphylococcus Other Than S. aureus

Abstract Staphylococcus spp., other than S. aureus (SOSA, formerly CoNS), are opportunistic pathogens often linked to biofilm infections on indwelling devices. Their rising antibiotic resistance highlights the need for novel therapies. Bacteriophages are promising due to their sp...

Contrasting reproductive strategies and their functional consequences in two populations of Opuntia robusta (Cactaceae)

Hermaphroditism is the predominant sexual condition in angiosperms, but populations of a single species can diverge markedly in their reproductive allocation and in the expression of their mating system. Opuntia robusta provides a suitable system to examine this divergence, as it...

Integrative taxonomic assessment reveals a new species of Sigmoidotropis (Leguminosae) from northeastern Brazil

Abstract Integrative analyses combining nrITS and trn K/ mat K phylogenetic analyses, palynology, ecological niche modelling, and morphology were conducted to reassess species limits within the Neotropical genus Sigmoidotropis (Leguminosae). Our phylogenetic framework recovered w...

Long-term diatom response to anthropogenic stressors in a Neotropical lake

Understanding tropical lake ecosystem responses to anthropogenic disturbance over long timescales is critical for assessing resistance, resilience, and regime shifts; however, such perspectives are rare in the Neotropics. We combined paleolimnological, limnological, and remote-se...

Quantum Theoretical, Chemo-Computational, and Comparative Molecular Coupling Studies of Two Enantiomeric Naphthoquinones, Alkannin and Shikonin, and Their Corresponding Indole Derivatives

The use of computational tools has become widespread in drug discovery as an effective approach to guide the development of new therapeutic agents, including potential cancer drugs. In addition, plant-derived secondary metabolites have attracted considerable interest as a valuabl...

Extratropical teleconnections in a multi-model ensemble nudged towards the observed QBO

The Quasi-Biennial Oscillation (QBO), the dominant mode of interannual variability of monthly-mean zonal winds and temperatures in the equatorial stratosphere, has a significant influence on the circulation in other regions of the stratosphere and troposphere in boreal winter. To...

From Glassware to Canvas: Synthesizing Art with Methyl Orange and Fluorescein

Abstract This work describes the synthesis of methyl orange and fluorescein and their applications in canvas painting. By modulation of the pH and concentration of methyl orange, a range of yellow, orange, and reddish hues can be obtained, illustrating its pH-dependent chromatic...

Far-Field Tsunami Observations of the 29 July 2025 Mw 8.8 Kamchatka Earthquake and Comparison with other Far-Field Tsunamis on the Mexican Pacific Coast

The Mw8.8 Kamchatka earthquake occurred offshore southern Kamchatka on July 29, 2025, generating a tsunami that propagated across the Pacific Ocean and produced a measurable sea-level disturbance along the Mexican Pacific coast. In this study, we analyze tide-gauge records along...

Determinants of Abl kinase stability and drug binding thermodynamics: Role of regulatory domains and phosphorylation

Abstract Activity dysregulation of Abl kinase is the primary cause for chronic myeloid leukemia (CML). Despite extensive characterization, the thermodynamic basis of Abl stability and inhibitor recognition remains incompletely understood. To characterize the cooperative folding o...

Antibiotic-resistant Acinetobacter calcoaceticus-baumannii complex in the environment: a narrative review

Abstract Acinetobacter calcoaceticus–baumannii complex comprises of both environmental and pathogenic bacterial species. Pathogenic species are responsible for nosocomial infections, which are increasingly difficult to treat due to growing resistance to antibiotics. In addition t...

Physicochemical, Mechanical and Biological Characterization of a PCL/PLA-Based Biocomposite for Potential Dental Post Applications in Primary Teeth

Early childhood caries frequently affects maxillary anterior primary teeth, and their rehabilitation remains a clinical challenge due to the lack of suitable resorbable intracanal posts. This study aimed to develop and characterize a biodegradable polymer-ceramic biomaterial for...

Rethinking family planning indicators: findings from a global expert consultation

The global family planning field has long relied on a few standard measures to assess program effectiveness and population-level outcomes, such as modern contraceptive prevalence, unmet need for family planning, and demand satisfied. Recognizing that these measures have substanti...

Ser715 Phosphorylation Induces β-Hairpin Unfolding and Destabilization of FOXM1 Autoinhibition.

FOXM1 is a cell proliferation-driving transcription factor activated by phosphorylation-induced conformational changes. In its inactive state, an intramolecular β-hairpin within the transactivation domain (TAD) binds the N-terminal repressor domain (NRD), forming a composite β-sh...

Tailoring Reactivity of Molecular Gallium Hydroxides via Chalcogen Bridging

Abstract We studied the influence of bridging chalcogen atoms (μ-E; E = S, Se) on the structure and reactivity of digallium dihydroxide complexes [{MeLGa(OH)}2(μ-E)] [E = S (4), Se (5); MeL = CH{CMe(NAr)}2–, Ar = 2,4,6-Me3C6H2]. Compounds 4 and 5 were synthesized from MeLGaCl2 an...

Effect of benthic organisms on Acropora palmata (Lamarck 1816) fragment survival and growth

Interactions between reef organisms such as overgrowth or release of allelopathic substances, constitute key elements to consider when planning and conducting restoration efforts. We investigated the impact of interactions with benthic organisms on the survival and growth of Acro...

Deformable precipitates locally modify fault-mediated plasticity for strength-ductility synergy

Precipitates in structural alloys are conventionally understood as passive obstacles to dislocation motion. Here we show that semi-coherent hexagonal close-packed precipitates in a low-stacking-fault-energy Ni50Co30Ru20 multi-principal element alloy cooperate with planar-fault pl...
