Summary: The number, duration, and depth of social relationships can impact social cognition, but the connection between sociality and other aspects of cognition has not been fully explored. This study is the first comparative study in fishes to examine whether complex social living is associated with better performance on spatial tasks. The results suggest that living in complex social groups does not necessarily enhance spatial learning capacity or other forms of cognition.

Summary: In cooperatively breeding species, the presence of unrelated male helpers in a group increases rates of extrapair paternity, while helper-sons do not have this effect. The relatedness of helpers does not impact nest productivity or nestling performance. Therefore, the relatedness of helpers does not directly affect extrapair paternity.

Summary: In socially structured populations, the survival and reproduction of dispersing individuals determine the formation of new groups. However, quantifying vital rates in dispersers is challenging due to the logistics of tracking wide-ranging animals. This study using meerkats as a model species shows that survival is lower for dispersing females compared to established residents, but subordinates in disperser groups have higher birth rates than those in established groups.

Summary: This study found that supervisor incivility is negatively associated with subordinates' sense of vitality and discretionary work effort (DWE), while vitality is positively associated with DWE. It also identifies that one way in which supervisor incivility negatively affects subordinates' DWE is by decreasing their sense of vitality.

Summary: Psychopathic men may display sexually aggressive behavior toward prospective partners and engage in sexual coercion within intimate relationships. This study examined the association between psychopathy and jealousy with men's engagement in partner sexual coercion. The findings showed that psychopathy is related to higher levels of suspicious jealousy and partner sexual coercion. Suspicious jealousy was found to partially mediate the relationship between men's psychopathy and engagement in partner sexual coercion. These results highlight the importance of psychopathy and jealousy in understanding men's use of coercive sexual behaviors within relationships.

Summary: The divergence of regulatory regions and gene regulatory network (GRN) rewiring is an important driver of cichlid phenotypic diversity. This study links miRNA-binding site turnover to GRN evolution across cichlids and identifies species-specific networks associated with cichlid phenotypic traits. The findings suggest that positive selection acting upon discrete mutations in regulatory regions plays a role in rewiring GRNs in rapidly radiating cichlids.

Summary: This study proposes a cooperative ankle-exoskeleton control strategy and evaluates its effectiveness in able-bodied participants. The results demonstrate that the proposed controller reduces participants' effort while maintaining their ability to counteract balance disturbances. Significant reductions in muscle activity were observed, indicating the potential of this strategy in supporting and improving balance control in individuals with motor disabilities.

Summary: Direct-to-consumer DNA tests have revealed cases where individuals discover that their presumed father is not their biological father, leading to non-paternity events (NPEs). This study investigated the psychiatric effects of discovering misattributed paternity, finding increased levels of depression, anxiety, and panic symptoms among those affected. Factors such as demographics, background information, family members' reactions, and personal reactions influenced the psychological impact. The ability to openly discuss and accept the discovery were identified as protective factors. This research highlights the importance of mental health professionals addressing the growing psychosocial stress caused by the popularity of direct-to-consumer DNA tests.

Summary: This study examines the evolution of monogamy in cichlids and marine reef fishes using phylogenetic comparative methods within a Bayesian framework. The results show that male territoriality is associated with the evolution of monogamy in cichlids, and both male and female territoriality are associated with monogamy in marine reef fishes. The study also found evidence against the biparental care hypothesis and suggests that female dispersal plays a role in the loss of monogamy in both groups. These findings provide new large-scale evidence for the link between mate guarding and the evolution of monogamy.

Summary: Sexually antagonistic selection has a significant role in the evolution of sex chromosomes. In the shell-brooding cichlid fish, a sexually antagonistic trait, body size, is linked to a 2.4-Mb sex-linked region with candidate genes for body size and sex determination. This study provides evidence supporting the hypothesis that sexually antagonistic traits are linked to young sex chromosomes.

Summary: This study investigates the impact of extreme weather on the prices of China's regional emission allowances, using panel data from four representative pilots in China. The findings reveal that extreme weather, particularly extreme heat, has a short-term lagged positive impact on carbon prices. The study also highlights the sensitivity of tertiary-dominated markets to extreme weather and the stronger positive impact during compliance periods, providing decision-making basis for emission traders to avoid losses caused by market fluctuations.

Summary: By studying male olive baboons, it is found that individuals who are more involved in parenting effort invest less in mating effort. These individuals also have lower proximity to their primary associates, indicating temporal constraints. There is also evidence that involvement in parenting effort negatively affects paternity success. In summary, males face tradeoffs between mating effort and parenting effort.

Summary: This study assessed the effects of abbreviated dual antiplatelet therapy (DAPT) compared to standard DAPT in high bleeding risk (HBR) patients who received biodegradable-polymer sirolimus-eluting stents. The study found that in HBR patients free from recurrent ischemic events, abbreviated DAPT was associated with similar adverse clinical events and lower bleeding rates compared to standard DAPT, regardless of the complexity of the intervention or patient condition.

Summary: This study models the coevolution of philopatry and alloparental care in cooperative breeding, finding that direct fitness benefits are the main driver for the evolution of philopatry and kin selection is mainly responsible for the emergence of alloparental care. The coevolution of philopatry and alloparental care is subject to positive feedback.

Summary: This study investigates whether the reciprocal behavior of Norway rats is based on copying by imitation or the application of the direct reciprocity decision rule. The results suggest that the rats provide help in accordance with the direct reciprocity decision rule rather than copying by imitation. This provides important evidence for our understanding of animal behavior.

Summary: Members of social groups negotiate with each other about the exchange of goods and services, and coercion may be involved if there are asymmetries between interacting partners. Cooperative breeders, such as the cichlid Neolamprologus pulcher, provide an excellent model to study such interactions. Our experimental results show that received aggression triggers increased alloparental brood care in subordinates, suggesting that fish use punishment to enforce cooperation.

Summary: Social evolution and dispersal decisions are closely related, but the factors driving philopatry or dispersal are often unclear. This study of cooperatively breeding fish demonstrates that philopatry benefits individuals by increasing breeding tenure and lifetime reproductive success. Male and female life histories differ, with males dispersing more and females more likely to inherit a breeding position. Male dispersal appears to be driven by differences in intrasexual competition rather than adaptive preference. Philopatry contributes to the maintenance of cooperative groups, with females obtaining greater benefits in social cichlids.

Summary: This study aims to determine the prevalence of ATTR-CM in elderly patients with severe aortic stenosis and evaluate the differences in clinical presentation and outcomes of patients with concomitant ATTR-CM undergoing transcatheter aortic valve implantation. The results showed that ATTR-CM was observed in 10.8% of patients with severe aortic stenosis, and elderly age, male sex, and prior carpal tunnel surgery were associated with the coexistence of ATTR-CM. However, there were no significant differences in peri-interventional risk and one-year clinical outcomes between patients with concomitant pathologies.

Summary: The mechanisms selecting for the evolution of cooperative breeding are debated, with kin selection theory being the central paradigm. However, direct fitness benefits may also play a role. The group augmentation hypothesis suggests that alloparental care may evolve to enhance group size. In this study, the researchers used cooperatively breeding cichlid fish to experimentally test this hypothesis, finding support for the group augmentation hypothesis.
