This requires an understanding of the mechanism of human behavioural response as well as the timing of decisions for future mobility. However, most human mobility data only record the executed mobility that results from decision-making, and not the timing of decisions. In this study, we used accommodation reservation data to extract the decision-making process in response to the changing epidemic situation and compared it with data on executed mobility, 'stay time' in workplaces and stay time in places other than home or workplaces to clarify when people decide on their mobility. We confirmed that the decision-making process estimated from accommodation reservation data can accurately predict human mobility. The decision-making process estimated from accommodation reservation data was more strongly associated with stay time in places other than home or workplaces than stay time in workplaces. Furthermore, the comparison between the estimated decision-making process and mobility data quantitatively revealed that mobility was the result of integrating two types of decisions made in recent weeks (within two and five weeks for mobility to workplaces and places other than home or workplaces, respectively) and previous weeks.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 7","pages":"250554"},"PeriodicalIF":2.9,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12307060/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754178","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}

In the field of invertebrate acoustic communication, reconstructing the acoustic properties of sound-producing forewings in crickets has been based on two very divergent methods, finite element modelling (FEM) and vibrometric measurements from preserved specimens. Both methods, however, make strong simplifying assumptions that have not been tested and the reliability of inferences made from either method remains in question. Here, we rigorously test and refine both reconstruction methods using the well-known Teleogryllus oceanicus model system and determine the appropriate conditions required to reconstruct the vibroacoustic behaviour of male forewings. We find that when using FEM it is not necessary to assume simplified boundary conditions if the appropriate parameters are found. When using preserved specimens, we find that the sample needs to be rehydrated for reliable reconstruction; however, it may be possible to accomplish rehydration in silico using FEM. Our findings provide a refined methodology for the reliable reconstruction of cricket songs, whether from fossils or preserved specimens from museums or field collections.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 7","pages":"251005"},"PeriodicalIF":2.9,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12307059/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754183","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}

However, the palaeoecological trajectory of acroporid growth is largely unknown. Here, we reconstruct a 5500-year acroporid trajectory from a hurricane-prone fringing reef off the northeast Yucatan coast and find that growth is not constant but punctuated by centennial-scale gaps. Local coastal archives show these gaps coincide with hurricane-frequency anomalies, which is consistent with local extirpation of acroporids following intense hurricane strikes. On each devastated reef, acroporids took hundreds of years to recolonize their former habitat, probably owing to naturally impaired sexual recruitment combined with substrate deterioration. By comparing trajectories across the Caribbean, we show that extirpation-recolonization events occur at different times between reefs, so gaps do not coincide. The resulting regional constancy of this palaeoecological baseline affirms that the historical demise of acroporids is unprecedented over the last 14 000 years and portends their absence on degraded reefs for hundreds of years into the future unless mitigated by restoration.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 7","pages":"250363"},"PeriodicalIF":2.9,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12307057/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754170","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}

Their capacity to self-organize, coupled with the presence of diverse cell types, means that organoids resemble their organ of origin in architecture and function. Organoids from intestinal tissues have been extensively used as a three-dimensional model for in vitro studies of the gut. However, they typically self-organize with basal-out polarity when cultured in a three-dimensional extracellular matrix scaffold, presenting a hurdle for experiments that require access to the apical epithelial surface. Methods to invert the surface polarity of intestinal organoids have been reported, but little information exists on how this change of polarity impacts gene expression and cell populations present within the organoids. To address this knowledge gap, we modelled both polarity states in intestinal organoids from two different ruminant species. Apical-out organoids largely retained the same gene expression profile as basal-out organoids. Moreover, a combination of RNA-seq and immunohistochemistry analyses demonstrated the retention of specific markers of enterocytes, enteroendocrine, goblet and tuft cells present in organoids of both polarity states. This study presents a comprehensive validation of apical-out ileal organoids, providing supporting evidence for the utility of this model in experiments that require access to the apical surface.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 7","pages":"250326"},"PeriodicalIF":2.9,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12307977/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754171","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}

In particular, how nuclear and cytoplasmic deformations respond to external forces is unclear. Here, we developed a microscopy-based technique to quantify the extensional uniaxial strains of the nucleus and cytoplasm during cell stretching, enabling direct measurement of their bulk mechanical responses. Using this approach, we identified a previously unrecognized inverse relationship between nuclear and cytoplasmic deformation in epithelial monolayers. We demonstrate that nucleo-cytoskeletal coupling, mediated by the Linker of Nucleoskeleton and Cytoskeleton (LINC) complex, regulates this anti-correlation (Pearson correlation coefficient approx. 0.3). Disrupting LINC abolished this relationship, revealing its fundamental role in intracellular deformation partitioning. Furthermore, we found that cytoplasmic deformation is directly correlated with stretch-induced nuclear shrinkage, suggesting a mechanotransduction pathway in which cytoplasmic mechanics influence nuclear responses. Lastly, multivariable analyses established that intracellular deformation can be inferred from cell morphology, providing a predictive framework for cellular mechanical behaviour. These findings refine our understanding of nucleo-cytoskeletal coupling in governing intracellular force transmission and mechanotransduction.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 7","pages":"250409"},"PeriodicalIF":2.9,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308074/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754181","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}

Here, we evaluated space use by dingoes, a territorial and socially monogamous group-living apex predator in Australia. We used data from remote camera traps and hourly fixes from GPS collars on eight individuals in five packs to identify variations in dingo territoriality and movement leading up to and including their annual breeding season, particularly in relation to an individual's known social status, sex and competition within their pack. Subdominant male detections increased outside their pack's home range during the breeding season, while subdominant female detections were unchanged. Furthermore, dominants spent more time (a higher proportion of detections) inside their territory as the number of pups present in their pack from the previous year increased. In common with other carnivores, these results suggest that ranging patterns depend on the sex and breeding status of the individual and potentially on levels of competition. Subdominant males may be exploring breeding opportunities outside of their own range, while dominants may remain in their territory to defend space, resources and reproductive partners. Understanding individual movement within and beyond their home range, can help to guide management actions both spatially and temporally.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 7","pages":"250255"},"PeriodicalIF":2.9,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12307064/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754173","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}

This variability can lead to treatment failure and the emergence of resistant bacteria. Understanding the factors influencing this variability is crucial for developing effective antibiotic treatments. The underlying cause of variation in susceptibility distribution within bacterial populations remains unclear, necessitating the development of new tools for measurement. Here, we use a droplet microfluidic single-cell antibiotic susceptibility assay and focus on antibiotic resistance conveyed by the TEM β-lactamases family. We investigate how the catalytic activity of β-lactamase, and the genetic characteristics of the host strains affect the susceptibility distribution within bacterial populations at the single-cell level. For this purpose, we selected TEM-1 with the least catalytic activity against cefotaxime, followed by its two variants, R164S and G238S, exhibiting moderate and significant catalytic activity, respectively. The results showed that increasing the catalytic activity causes an increase in the population's mean level of antibiotic resistance. While the type of β-lactamase influences the susceptibility distribution of the strains, this effect is independent of the catalytic activity of the strains. Besides, the genetic characteristics of the strains receiving the β-lactam resistance gene is an important factor that plays a role in the distribution of susceptibility.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"12 7","pages":"242143"},"PeriodicalIF":2.9,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12307058/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754169","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}

Fitness declined with increasing social instability, but this relationship was not statistically significant and did not support our expectations. We found no statistically significant moderating effects of social system component, sex, age, taxonomic group and study type (experimental versus observational) on either stress or fitness outcomes. However, females and adults exhibited stronger positive stress correlations and stronger negative fitness correlations, and observational studies showed a similar trend when compared with experimental studies.

The analysis demonstrated that urea-oxidation pathways generally require significantly less energy input than water electrolysis. Among the examined reactions, the oxidation of urea to gaseous nitrogen and carbonate ions was identified as the most efficient, with an electricity economy of -4650.83 J mol-1 and an atom economy of 6.4%. However, practical application is hindered by issues such as low product selectivity and high anodic potentials dictated by the redox thermodynamics of commonly used nickel-based catalysts.
