Symmetric structures are more stable and easier to describe and compress, which is why they may have been preferred as building blocks in natural selection. The idea that natural languages undergo an evolutionary process akin to the evolution of species has been pervasive in the study of language. This process might result in symmetric patterns as in other natural structures, but the notion of symmetry is rarely associated with the study of natural language. In this study, we look for symmetric patterns in text data, considering the length of subword units under a range of possible subword analyses. We study the length of subword units in 32 languages and discover that the splits of long words tend to be symmetric regardless of the segmentation method and that some automatic methods give symmetric splits at all word lengths. These results include natural language in the set of phenomena that can be described in terms of symmetry, opening a new research avenue for the empirical study of text data as a structure comparable to various other structures in the natural world.</p>","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 8","pages":"250295"},"PeriodicalIF":2.9,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12370235/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144967184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These proteins are implicated in parasite adhesion to and invasion of host cells, immune response modulation and structural roles in the cyst wall. In this study, we characterized two key <i>N. caninum</i> SRS proteins, NcSAG1 and NcSRS2, through sequence analysis, structural modelling, biophysical characterization and immunochemical assessment. Sequence analyses revealed conserved domains, including hallmark D1 and D2 regions, but with significant sequence divergence. Using AlphaFold, we constructed reliable structural models, confirming conserved features such as disulfide bond patterns and dimerization. Structural comparisons demonstrated a high degree of conservation within D1 domains despite low sequence similarity. Recombinant NcSAG1 and NcSRS2 were expressed as soluble and stable proteins in <i>Drosophila melanogaster</i> S2 cells, achieving yields comparable to the most efficient prokaryote expression systems. Size exclusion chromatography and dynamic light scattering demonstrated their dimeric nature and structural stability, with melting temperatures exceeding 50°C. Circular dichroism spectroscopy confirmed their correct secondary structure content, validating proper folding and structural integrity. Antigenicity assays demonstrated universal recognition by sera from experimentally and naturally infected hosts, highlighting their potential as diagnostic markers or vaccine candidates. Comparative structural analysis of 219 SRS family members, based on sequence and AlphaFold-predicted structures, revealed conserved cysteine, proline and tryptophan motifs. Hierarchical clustering and phylogenetic analyses identified key evolutionary clusters, correlating structural divergence with functional specialization. Discrepancies between sequence- and structure-based trees underscored instances of structural evolution not reflected in sequence data.

We have identified a sexually dimorphic innate reward behaviour in <i>Drosophila melanogaster</i> that varies depending on the age, sex and mating status in young adults. Our results suggest that the rewarding neuropeptide <i>corazonin</i>, the transcription factor <i>apontic</i> and juvenile hormone signalling regulate naive ethanol olfactory preference responses during early stages of adulthood. Pharmacological blockade of juvenile hormone via precocene increases naive ethanol olfactory preference in females and males, which is partially phenocopied by the knockdown of juvenile hormone receptors <i>met</i> and <i>gce</i> globally in the nervous system as well as specifically in the mushroom body. The observed changes in naive ethanol olfactory preference suggest a novel role of juvenile hormone in the maturation of dimorphic ethanol behaviours during the transition from increased naive ethanol olfactory preference observed in young flies to decreased naive ethanol olfactory preference responses in older flies. Mating decreases naive ethanol olfactory preference in males, likely acting through rewarding pathways such as <i>neuropeptide F</i> and <i>corazonin</i>. Our study suggests an early evolutionary emergence of hormonal mechanisms regulating ethanol-dependent behaviours, as corazonin and juvenile hormone functionally resemble the vertebrate gonadotropin-releasing hormone and thyroid hormones, respectively. The results described here pave the way for future studies to further investigate the molecular and cellular mechanisms by which a non-reproductive, yet sexually dimorphic behaviour matures using <i>Drosophila</i> as a model.

These results suggest that crevice openings and ceilings are key microhabitats for CCA and therefore may also be important for reef building and stabilization.
