This study reveals that AI is asymmetrically stereotyped, being more closely associated with socially dominant groups. This conclusion is based on these investigations of AI's associations along the warmth-competence dimensions of the stereotype content model, its connections with socially advantaged (e.g., men, young, rich, white) versus disadvantaged (e.g., women, old, poor, non-white) demographic groups, and its perceived impact on high- versus low-prestige occupations. Across four studies using language-based analyses with static word embeddings, BERT-based models, and GPT-4o, as well as human-participant experiment validation, it is found that i) AI is strongly associated with high competence but exhibits variability in the warmth dimension (Study 1); ii) AI is more closely linked to advantaged demographic groups (Study 2); iii) advantaged demographic groups are semantically closer to AI than their disadvantaged counterparts along the warmth-competence dimensions (Study 3); and iv) high-prestige occupations (rather than low-prestige ones) are associated more strongly with AI's benefits than with its threats. Together, these findings indicate that public perceptions of AI are systematically biased toward socially dominant groups, potentially reinforcing existing social inequalities and raising concerns about an emerging \"AI divide.\"","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e08623"},"PeriodicalIF":14.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A central juncture in molting is the periodic and coordinated regulation of molting-responsive mRNAs, which are essential for degrading the old cuticle and forming a new one. Knowledge is lacking of how molting-responsive molecules function cooperatively and timely. Here, multi-stage m6A modification levels, m6A reader condensation, and transcriptome analyses are developed to track the dynamic functional coupling for molting signals. The results showed that the molting-responsive mRNAs are downregulated with the decrease of m6A modification levels from pre-molt to the molt stage. The eIF3-S6 is further identified, as an m6A reader, can directly bind to EcR A335 and Cht10 A7589. The low mRNA m6A modification in the molt stage facilitates eIF3-S6 to undergo liquid-liquid phase separation (LLPS) by binding m6A-containing EcR/Cht10 into condensed droplets for stabilizing the mRNAs. Disruption of m6A modification or breaking phase separation can cause a disorder of the new/old cuticle synthesis/degradation in molting. The disorder results in abnormal and unsuccessful molting, ultimately leading to the death of nymphs. Overall, the data mechanistically highlight an example of how two central machineries, m6A modification and LLPS, can accurately and functionally cooperate to optimize molting-responsive gene expression for insect molting.","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e10505"},"PeriodicalIF":14.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exosomes are implicated in both the injury and recovery processes of ischemic stroke. While enhanced glycolysis is linked to exosome biogenesis, its regulatory mechanisms remain largely unexplored. Here, an increase in the number of exosomes within the cerebrospinal fluid (CSF) and plasma in acute ischemic stroke is observed. Hypoxia selectively enhanced the exosomes biogenesis in astrocytes. Through RNAi screening, we identified the glycolytic enzyme hexokinase 2 (HK2) as a key promoter of hypoxia-induced exosomes. HK2 facilitates the formation of intraluminal vesicles (ILVs), the precursors of exosomes, without affecting their degradation in lysosomes. HK2 directly phosphorylates neutral sphingomyelinase 1 (nSMase1), a critical enzyme involved in the lipid biogenesis pathway of exosomes. Moreover, hypoxia-induced astrocytic exosomes disrupt cerebrovascular endothelial tight junction proteins. Astrocyte-specific knockdown of HK2 significantly reduces exosomes release and alleviates brain injury caused by middle cerebral artery occlusion (MCAO). Notably, MCAO markedly increased the phosphorylation of nSMase1, which is effectively abolished by astrocytic HK2 knockdown. In conclusion, this study reveals a non-metabolic role of HK2 in exosomes biogenesis via its protein kinase activity, offering a potential therapeutic target for stroke.","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e01894"},"PeriodicalIF":14.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although co-catalyst engineering affords a convenient strategy to dominate spatial charge migration to the ideal active sites, the conventional co-catalyst modification strategy fails to exquisitely mediate the interface between co-catalyst and semiconductor matrix, along with tedious synthesis procedures. Herein, an insulating polyelectrolyte (NCP), poly(diallyldimethylammonium chloride), is uniformly and seamlessly coated on the transition metal chalcogenides (TMCs) substrates via a facile electrostatic self-assembly approach and strategically serves as the highly efficient catalytic active sites for stimulating multifarious photoredox catalysis, including selective organic transformation and CO2 reduction. The crucial roles of such NCP are unambiguously unraveled via comprehensive experimental and theoretical investigations, which include increasing reactant adsorption, providing active sites, and most importantly, boosting interfacial charge transfer rate. The electron-withdrawing capability of NCP fosters the effective charge separation over TMCs, leading to the concomitantly improved and stable photocatalytic activities toward aromatic nitro compounds reduction and CO2-to-syngas conversion under visible light. Our work could strengthen our fundamental understanding of the generic unanticipated charge transport characteristics of insulating polymers for solar energy conversion.","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e07670"},"PeriodicalIF":14.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, its sluggish kinetics in acidic media and reliance on expensive noble metal catalysts limit its efficiency in these applications. Spinel cobalt(II, III) oxide (Co3O4)-based catalysts are cost-effective alternatives with high theoretical catalytic activity. However, their practical deployment is hindered by their poor stability in acidic electrolytes. This review critically examines recent advances in enhancing the stability of spinel Co3O4-based catalysts for acidic OER. The fundamental reaction mechanisms of acidic OER are first analyzed to illustrate how different catalyst design strategies can be used to improve their stability. Next, five key catalyst design strategies reported in recent studies are summarized: 1) constructing protective surface layers, 2) modulating reaction pathways, 3) controlling cobalt redox dynamics, 4) tuning cobalt-oxygen covalency, and 5) stabilizing lattice oxygen. Further, recent research progress in understanding the structure-activity-stability relationship of spinel Co3O4-based catalysts is summarized, with a focus on identifying their catalytically active sites, tracking surface reconstruction, and elucidating degradation mechanisms. This review ends with a discussion of future research directions for addressing key challenges in realizing durable, high-performance Co3O4-based catalysts for acidic OER applications.","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e09415"},"PeriodicalIF":14.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In seeking sustainable alternative solutions, cultivated meat technology typically utilizes differentiation of myogenic progenitor cells (MPCs) into muscle cells for in vitro meat production. However, understanding the molecular determinants governing MPC differentiation into muscle cells, and the potential enhancement of this process through modulation of signaling pathways, remains limited. Herein, we characterized the molecular landscape associated with bovine MPC differentiation in vitro by employing multiomics, and explored its augmentation by small molecules, together leading to identification of media that enhanced myogenic differentiation compared with conventional methods in both 2D cultures and tissue-engineered 3D skeletal muscle constructs. Through bulk and single-cell transcriptomics and proteomics, we compared conventional and enhanced differentiation media, demonstrating that the enhanced media gave rise to unique progenitor-like cell populations, while simultaneously promoting differentiation into myocytes and contractile myotubes expressing a wide array of myogenic markers that more closely resemble bovine muscle cells in vivo.

Single-cell RNA sequencing of E13.5 mouse embryos suggests that maternal obesity impairs embryonic myogenesis, primarily during myotube formation, and is correlated with the downregulation of myogenin (Myog) expression. Spatial transcriptomic sequencing further confirms these findings. Conversely, maternal obesity induces the upregulation of RelA, a transcription factor and inflammatory signaling effector, in the myogenic cells of obese embryos. Additionally, single-cell ATAC sequencing suggests that a cis-regulatory region, located 4 kb proximal to the Myog promoter, exhibits coordinated expression with Myog and acts as an enhancer of Myog. In obese embryonic myogenic cells, RelA is recruited to this region, inhibiting Myog expression and myotube formation. Notably, in vitro RelA knockdown or inhibition rescues Myog expression and promotes myogenic differentiation. Similarly, metformin treatment of obese mothers restores embryonic Myog expression and myogenesis by suppressing RelA.
