AbstractAlpine lakes, characterized by isolation, low temperatures, oligotrophic conditions, and intense ultraviolet radiation, remain a poorly explored ecosystem for RNA viruses. Here, we present the first comprehensive metatranscriptomic study of RNA viruses in Lake Nam Co, a high-altitude alkaline saline lake on the Tibetan Plateau. Using a combination of sequence– and structure-based homology searches, we identified 742 RNA virus species, including 383 novel genus-level groups and 84 novel family-level groups exclusively found in Lake Nam Co. These findings significantly expand the known diversity of theOrthornavirae, uncovering evolutionary adaptations such as permutated RNA-dependent RNA polymerase (RdRP) motifs and distinct RNA secondary structures. Notably, 14 previously unknown RNA virus families potentially infecting prokaryotes were predicted, broadening the known host range of RNA viruses and questioning the traditional assumption that RNA viruses predominantly target eukaryotes. The presence of auxiliary metabolic genes (AMGs) in viral genomes suggested that RNA viruses (familiesf.0102and Nam-Co_family_51) exploit host energy production mechanisms in energy-limited alpine lakes. Low nucleotide diversity, SNP frequencies, and pN/pS ratios indicate strong purifying selection in Nam Co viral populations. Our findings offer insights into RNA virus evolution and ecology, highlighting the importance of extreme environments in uncovering hidden viral diversity, and further shed light into their potential ecological implications, particularly in the context of climate change.Significance StatementThis study unveils the hidden diversity and complexity of RNA viruses in the high-altitude ecosystem of Lake Nam Co, significantly expanding the known RNA virome. The discovery of novel viral clades, expanded potential host ranges, and unique evolutionary adaptations emphasizes the importance of exploring extreme environments to uncover viral diversity and evolutionary pathways. Our findings offer critical insights into viral evolution, host-virus interactions, and the ecological roles of RNA viruses, particularly in the context of climate change and environmental resilience.

AbstractRecognizing skillful group members is crucial for making optimal social choices. Whether and how nonhuman animals attribute skill to others is still debated. Using a lever-operated food box, we enhanced the foraging skill of a single male (the specialist) in one zoo housed and two wild groups of Guinea baboon (Papio papio). We measured group member’s behav-ioral responses before, during, and after our manipulation to reveal whether they focused on the outcome of the males’ actions or changed their assessment of his long-term value. During the manipulation, females in the specialist’s unit, but not the wider group, competed over ac-cess to the specialist - increasing their grooming of him tenfold and aggression near him four-fold. Both behaviors were predicted by the amount each female ate from the food box and re-turned to baseline within two weeks of its removal. This behavioral pattern supports an out-come-based assessment where females responded to male-provided benefits (utility) rather than attributing competence (value).TeaserGuinea baboon females monopolize males in relation to their current perceived utility.

Published: July 2024

ABSTRACTDevelopment of multicellular organisms requires well-orchestrated interplay between cell-intrinsic transcription factors and cell-cell signaling. One set of highly conserved transcription factors that plays diverse roles in development is the SoxC group.C. eleganscontains a sole SoxC protein, SEM-2. SEM-2 is essential for embryonic development, and for specifying the sex myoblast (SM) fate in the postembryonic mesoderm, the M lineage. We have identified a novel partial loss-of-functionsem-2allele that has a proline to serine change in the C-terminal tail of the highly conserved DNA-binding domain. Detailed analyses of mutant animals harboring this point mutation uncovered new functions of SEM-2 in the M lineage. First, SEM-2 functions antagonistically with LET-381, the soleC. elegansFoxF/C forkhead transcription factor, to regulate dorsoventral patterning of the M lineage. Second, in addition to specifying the SM fate, SEM-2 is essential for the proliferation and diversification of the SM lineage. Finally, SEM-2 appears to directly regulate the expression ofhlh-8, which encodes a basic helix-loop-helix Twist transcription factor and plays critical roles in proper patterning of the M lineage. Our data, along with previous studies, suggest an evolutionarily conserved relationship between SoxC and Twist proteins. Furthermore, our work identified new interactions in the gene regulatory network (GRN) underlyingC. eleganspostembryonic development and adds to the general understanding of the structure-function relationship of SoxC proteins.AUTHOR SUMMARYSoxC transcription factors play important roles in metazoan development. Abnormal expression or function of SoxC factors has been linked to a variety of developmental disorders and cancers. It is therefore critical to understand the functions of SoxC proteins in vivo.C. eleganshas a single SoxC transcription factor, SEM-2, that is known to regulate a fate decision between a proliferative progenitor cell vs. a terminally differentiated cell during postembryonic mesoderm development. In this study, we report new functions of SEM-2 in postembryonic mesoderm development via our studies of a partial loss-of-function allele ofsem-2. Our work uncovers new regulatory relationships between SEM-2/SoxC and the FoxF/C transcription factor LET-381, and between SEM-2/SoxC and theC. elegansTwist ortholog HLH-8. Our findings suggest that the SoxC-Twist axis, including the downstream targets of Twist, represents an evolutionarily conserved regulatory cassette important in metazoan development.
Eyes robustly blink to musical beats like tapping
Authors: Wu Yiyang , Teng Xiangbin , Du Yi 
Published: July 2024

AbstractAuditory-motor synchronization with musical rhythm may extend beyond overt body movements like fingers or feet. Through four experiments combining eye-tracking, neurophysiological and structural imaging approaches with 123 young non-musicians, we demonstrated robust synchronization of spontaneous eye blinks with musical beats. The blinking rate consistently aligned with the beat rate across various tempi and independent of melodic cues. Blinking exhibited beat phase-specific tuning, with inhibition immediately before beats and increased frequency afterward. Variations in blink-beat synchronization corresponded to the difference in microstructural lateralization of auditory-parietal connectivity. EEG recordings revealed a dynamic correspondence between blink and neural beat tracking. Mechanistically, this synchronization reflects dynamic auditory attention and temporal modulation of visual sampling. Our findings establish ‘eye tapping’ as a novel behavioral paradigm, expanding the behavioral repertoire of auditory-motor synchronization. It underscores the intricate relationship between music rhythms and peripheral oculomotor system, proposing a cross-modal active sensing and embodied experience in music perception.
What determines the vertical structuring of pelagic ecosystems in the global ocean?

Published: July 2024

AbstractOffshore pelagic ecosystems are composed of vertically and functionally distinct epipelagic, migrant and resident mesopelagic communities. While this vertical structure plays a key role in carbon sequestration and in supporting important fisheries, there is still no consensus on the respective contribution of the environmental factors (light, oxygen) and processes controlling it at both global and regional scale. Here we combine mechanistic modelling and acoustic observations from the worldwide Malaspina scientific campaign to show that, while underwater light intensity is the primary factor controlling the vertical distribution and migration of pelagic organisms globally, oxygen plays a critical role in limiting the depth of migratory communities and the abundance of mesopelagic communities in Oxygen Minimum Zones. Furthermore, we show that a faithful reproduction of acoustic observations in some regions of the global ocean (southern Indian Ocean, western Pacific) cannot be achieved without separating migratory and resident mesopelagic communities into deep and shallow groups. By proposing a unified mechanistic model and an archetypical ecosystem structure constrained by comprehensive acoustic observations, this study provides a consistent understanding of the vertical structure and function of global pelagic ecosystems and paves the way for more reliable estimates of their climate-induced variability and change.

Published: July 2024

AbstractPlant cells are contained inside a rigid network of cell walls. Cell walls are highly dynamic structures that act both as a structural material and as a hub for a wide range of signaling processes. Despite its crucial role in all aspects of the plant life cycle, live dynamical imaging of the cell wall and its functional properties has remained challenging. Here, we introduce CarboTag, a modular toolbox for live functional imaging of plant walls. CarboTag relies on a small molecular motif, a pyridine boronic acid, that targets its cargo to the cell wall, is non-toxic and ensures rapid tissue permeation. We designed a suite of cell wall imaging probes based on CarboTag in any desired color for multiplexing. Moreover, we created new functional reporters for live quantitative imaging of key cell wall features: network porosity, cell wall pH and the presence of reactive oxygen species. CarboTag opens the way to dynamical and quantitative mapping of cell wall responses at subcellular resolution.
Experimental and simulation analysis of mechanical property degradation of corrosion thinning of Q355 steel for transmission towers
Authors: Guo Xin , Tu Jiesong , Fan Zhibin , Du Baoshuai , Shang Hongfei , An Jiangfeng , Jia Dan 
Published: July 2024

Purpose
Corrosion thinning reduces the effective cross-sectional areas of steel structures and degrades their mechanical properties. This study aims to investigate the relationship between the corrosion thinning of carbon steel for transmission towers and the degradation of its mechanical properties.

Design/methodology/approach
A macroscopic finite element model of a transmission tower was established and then combined with the corrosion thinning and mechanical properties of Q355 steel in different test periods measured in neutral salt spray, SO2 atmosphere and wet heat environments to conduct a finite element simulation of a transmission tower with different corrosion thinning of Q355 steel.

Findings
When the residual thickness of the tower leg angle was reduced to 4.03 mm, the maximum stress solved in the simulation exceeded the yield strength, with the tower already at risk of collapse owing to corrosion failure under extreme conditions of basic wind speed.

Originality/value
This study innovatively utilises transmission tower finite element models and experimental data from mechanical degradation experiments to quantify the relationship between corrosion thinning and the mechanical properties of Q355 steel, ensuring the effective assessment of the mechanical properties of corroded transmission towers.
Methods and value of storytelling for stakeholders in post-disaster tourism scenarios
Authors: Wright Daniel William Mackenzie , Ben Salah Manar 
Published: July 2024

Purpose
The tourism sector continues to be an engine for economic growth for communities (Jenkins, 1980), and in post-disaster scenarios, destination can be overwhelmed with challenges, particularly for the local community. However, it is essential to seek the most effective path of recovery for individuals and communities. Gaps in contemporary post-disaster literature remain, as the focus often centres on infrastructure and economic developments (Cox and Perry, 2011). This paper aims to address such gaps by offering new ideas around the value of recovery focusing more on the victims, their stories and the role of tourism.

Design/methodology/approach
As a theoretical paper, the applied method is described as a convenient approach to data collection and analysis. The methodological reasoning is down to the selection and examination of sources used to establish new theoretical understandings. The study applies a pragmatic research approach to embrace the spectrum of views that are present within the constructivist and positivist. The pragmatic philosophical approach supports multi-disciplinary studies and ensures a more holistic consideration of social conditions is embraced.

Findings
This paper offers new knowledge and ideas for post-disaster recovery scenarios. It presents a model that incorporates a range of (traditional, digital and immersive) methods and platforms in which stories can be shared and presented. It argues that allowing victims to share stories in different formats could support rehabilitation while also providing stronger, powerful narratives for tourists, leading to more effective tourism experiences.

Originality/value
Disasters leave individuals and communities in devastation and with potentially lifelong trauma. In rehabilitation of victims is a vital ingredient to the recovery of a destination and its social fabric. This research offers new ideas around the use of digital technologies to generate stories of value that not only support victims of disasters but also offer visitors the opportunity to gain a deeper understanding of challenges and difficulties of dark places, often seen as a key part of the visitor experience and motive to places of tragedy.

Authors: Dsouza Marcella , Phadtare Anuradha , Vyas Swapnil S. , Shinde Yogesh , Jadhav Ajit 
Published: July 2024

Purpose
This study aims to understand how climatic drivers of change will affect rural communities living in the hot semiarid region of Bhokardan Taluka of Jalna district in the Indian state of Maharashtra. In the context of the economic and social change they are experiencing, the concern is to evolve ways that enable them to cope with, adapt to and benefit from these challenges.

Design/methodology/approach
The focus of most of the climate change studies is on the short- to long-term trends of weather parameters such as rainfall, temperature and extreme weather events. The impact of climate variability and changing patterns on the local communities, the local economy, livelihoods and social life in specific geographies is less explored.

Findings
As the impacts of climatic and nonclimatic drivers of change are cross-sectoral, diverse, multidimensional, interlinked and dynamic, this study has adopted a transdisciplinary “research-in-use” approach involving multidisciplinary teams covering the aspects such as changes in land use and land cover, surface and groundwater status, edaphic conditions, crops and livestock, climate analysis including projected changes, socioeconomic analysis, people’s experience of climate variability and their current coping strategies and resilience (vulnerability) analysis of communities and various livelihood groups.

Research limitations/implications
The study was based on the peoples’ perspective and recommendation based on the local communities ability to cope up with climate change. However, a statistical analysis perspective is missing in the present study.

Originality/value
Based on these findings, a set of implementation-focused recommendations are made that are aimed at conserving and enhancing the resilience of the foundations that uphold and sustain the social and economic well-being of the rural communities in Bhokardan taluka, namely, land, water, agriculture, livestock, food and nutrition security, livelihoods, market access and social capital.

Authors: Srivastava Richa , Sanjeev M.A. , Gupta Srikant 
Published: July 2024

PurposeHeightened public concerns for the global environment due to human overexploitation have given rise to many green product initiatives by businesses. Green cosmetics (GC) are products developed and marketed based on ecological sustainability and have shown increasing consumer appeal worldwide. The current research investigates the antecedents of green cosmetics consumption among Indian GC users, hitherto un-investigated comprehensively.Design/methodology/approachThe study is a cross-sectional pairwise comparison of green evaluation criteria for cosmetics using an expert panel of thirty Indian cosmetic users using a fuzzy analytic hierarchy process (F-AHP) and investigate the impact of a comprehensive list of antecedents on the multi-criteria category consumption decision.FindingsThe study results indicate that perceived consumer effectiveness is the most critical factor for green cosmetics consumption in India, followed by brand trust, behavioural control, and environmental effectiveness. The least important factors are price and social norms.Research limitations/implicationsAs the GC category is at nascent stage in India the investigation is limited to the GC category innovators – a set of people high in intellectual and financial resources. The study is also limited to women users as the male cosmetic market in the country is still very small.Practical implicationsThe study results can help marketers in designing and implementing GC related marketing strategies to deliver higher customer value to the target segment. Academicians can use the study results for better prediction of category related behaviour of consumers.Social implicationsThe study results will help promote GC category adoption and usage which can benefit the environment and consumer health.Originality/valueThe study contributes to literature and practice by assessing a comprehensive set of critical antecedents to GC adoption using a novel approach of F-AHP and an expert user panel. The study results offer insights to marketers that can be used to develop suitable strategies to convert non-GC users into GCs in India and similar markets, improving category penetration and benefitting marketers, retailers, users, and the environment.
