This corresponds to a huge variation in fluid flow regimes, characterized by paddle-scale Reynolds numbers ([Formula: see text]) ranging from the orders of [Formula: see text] (viscosity dominated) to [Formula: see text] (inertially dominated). Though the rhythmic stroking of the paddles is conserved across species and developmental stages, the hydrodynamic scalability of metachronal rowing has not been examined across this broad [Formula: see text] range. Using a self-propelled metachronal paddling robot, we examine swimming performance changes across four orders of magnitude variation in [Formula: see text] most relevant to crustaceans ([Formula: see text] to [Formula: see text]). We found that wake Strouhal number ([Formula: see text]), which characterizes momentum transfer from paddles to the wake, was unchanged for [Formula: see text] ([Formula: see text]). This is within the reported range of Strouhal numbers of various flying and swimming animals. Peak dimensionless circulation of paddle tip vortices increased linearly with stroke kinematics but was mostly unaffected by fluid viscosity. These findings show that the swimming performance of metachronal rowing is conserved across widely varying flow regimes, with dimensionless swimming speed scaling linearly with [Formula: see text] across the entire tested range.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 227","pages":"20240822"},"PeriodicalIF":3.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12133342/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

To investigate gender differences in resume writing and how they are associated with gender gaps in the labour market, we analysed 6.9 million resumes of Chinese job applicants in this study. Results reveal substantial gender resume differences, where women and men show distinct patterns in both simple language features and high-level semantic structures in the word embedding space of resumes. In particular, women tend to use shorter resumes, longer sentences and a more diverse set of unique words. Neural network models trained on resumes can predict gender with 80% accuracy, and the accuracy decreases with education levels and text standardization requirements. Moreover, while better language skills are associated with higher salary expectations, this positive relationship is magnified for men but weakened for women in women-dominated occupations. This study presents a new venue for the understanding of gender differences and provides empirical findings on how men and women are different in self-portraying and job seeking.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 227","pages":"20240784"},"PeriodicalIF":3.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12134937/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 activity at small scales, where they search for food sources in a highly heterogeneous and dynamic environment, for example controls the decomposition of organic matter. To be effective, these microorganisms have evolved sophisticated behaviours, which include extremely rapid swimming speeds, a precise chemosensing ability and particular swimming patterns. One of these peculiar motility patterns often recorded in the ocean is run-reverse (Mitchell et al 1996 Clustering of marine bacteria in seawater enrichments. Appl. Environ. Microbiol. 62, 3716-3721.

(doi:10.1073/pnas.1019199108), where bacteria alternate between forward (pushing) and backwards (pulling) swimming modes. In this study, we investigate whether this swimming pattern offers advantages to microorganisms that actively track small and light food sources carried by a dynamic flow. For that we develop an individual-based model, where elongated self-propelled particles (microswimmers) track passive food particles (tracers) in a random kinematic flow field, also known as synthetic turbulent flow. We compare the widely studied motility pattern of run-and-tumble with the run-reverse mode used by marine bacteria. Our results reveal a significant hydrodynamic advantage of the run-reverse motility pattern of bacteria combined with their elongated shapes for efficiently tracking light food sources in dynamic fluid environments.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 227","pages":"20250037"},"PeriodicalIF":3.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12173485/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144317246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

When designing such models, it is important to accurately account for sources of stochasticity. However, doing so can be computationally expensive and analytically untractable, posing limits on the extent of our explorations and on parameter inference. Here, we explore this challenge using the example of a simple auto-negative feedback motif, in which we incorporate stochastic variation due to transcriptional bursting and noise from finite copy numbers. We find that transcriptional bursting may change the qualitative dynamics of the system by inducing oscillations when they would not otherwise be present, or by magnifying existing oscillations. We describe multiple levels of approximation for the model in the form of differential equations, piecewise-deterministic processes and stochastic differential equations. Importantly, we derive how the classical chemical Langevin equation can be extended to include a noise term representing transcriptional bursting. This approximation drastically decreases computation times and allows us to analytically calculate properties of the dynamics, such as their power spectrum. We explore when these approximations break down and provide recommendations for their use. Our analysis illustrates the importance of accounting for transcriptional bursting when simulating gene regulatory network dynamics and provides recommendations to do so with computationally efficient methods.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 227","pages":"20250170"},"PeriodicalIF":3.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12187408/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144484829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

To avoid water loss, terrestrial insects are covered with a thin, chemically complex layer of cuticular hydrocarbons (CHCs), which also serve as communication signals in many species. Effective protection against desiccation depends on the phase behaviour of this layer. However, little is known about CHC phase behaviour, how it changes with temperature and how insects adjust it to cope with changing temperatures. We addressed these questions, studying the viscosity of CHCs from two European ant species using microrheology. Here, the CHC layers consisted of a gel phase and a liquid phase. The liquid phase itself was heterogeneous, characterized by a bimodal distribution of local viscosities. The higher viscosity mode had a viscosity similar to honey (600-1000 mPa s), while the lower viscosity mode resembled olive oil (100-150 mPa s). The bimodality suggests that each mode may fulfil a distinct function, thereby enabling the simultaneous execution of otherwise conflicting functions. Furthermore, ants kept under warm conditions showed a significantly more viscous CHC layer, tentatively suggesting that CHC composition is adjusted to maintain a homeostatic viscosity and minimize water loss. These insights contribute to our understanding of the physical mechanisms that underlie the biological functions of the CHC layer.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 227","pages":"20250099"},"PeriodicalIF":3.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12151604/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144266524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Taking Guangzhou as the case, we develop a dynamic model to identify the optimal rainfall range for mosquito population development. Using mosquito surveillance and meteorological data, we estimate the optimal weekly rainfall range as 131.2-212.8 mm. Additionally, we use the distributed lag nonlinear model to analyse the correlation between rainfall and local cases, providing cross-validation. We consequently introduce a novel rainfall index to quantify its causal effects on dengue burden and use a hurdle regularization model to assess the interplay between imported cases, rainfall and temperature in shaping dengue outbreaks. The cases in 2014 and 2015 are predicted by fitting the model to epidemic data between 2006 and 2013. Our proposed rainfall index outperforms existing indices in both model fitting and prediction accuracy. Additionally, switching 2014 and 2015 index values shows a significantly larger 2015 outbreak and smaller 2014 wave, unlike adjustments to temperature or imported case data, highlighting rainfall's dominant role in shaping Guangzhou dengue outbreaks. Although the parameters and the results are restricted to Guangzhou, the fundamental framework can be widely applied to any other region by including the specific data.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 227","pages":"20250029"},"PeriodicalIF":3.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12187404/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144484827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Heterogeneous environments may reduce the influence of selection on evolutionary outcomes through various mechanisms, including pinning of genetic lineages and of the population fronts. These effects play significant roles in enabling competitive release of otherwise trapped mutations. In this study, we show that environments containing random arrangements of 'hotspot' patches, where locally abundant resources enhance growth rates equally for all sub-populations, give rise to massively enriched deleterious mutant clones. We derive a geometrical optics description of mutant bubbles, which result from interactions with hotspots, which successfully predicts the observed increase in mutant survival. This prediction requires no fitting parameters and holds well in scenarios of rare mutations and of adaptation from standing variation. In addition, we find that the influence of environmental noise in shaping the fate of rare mutations is maximal near a percolation transition of overlapping discs, beyond which mutant survival decreases.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 227","pages":"20240698"},"PeriodicalIF":3.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12173482/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144317248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
