Summary: Father absence is associated with earlier age at menarche, with both genetic and environmental factors potentially influencing this association. This study aimed to replicate and expand previous genomic research on this topic, using a prospective longitudinal cohort study. The findings showed that a polygenic score could not explain the father absence/AAM association, and there was no interaction between father absence and the polygenic score. However, results regarding LIN28B largely replicated previous work, showing that LIN28B variants predicted later age at menarche in girls with a present father, but this effect was absent or reversed in girls with a absent father.

Summary: This study examines the relationship between growing up in father-absent households and pubertal timing in Korean adolescents. While no association was found between father absence and earlier onset of menarche in girls, boys in father-absent households reported their first nocturnal ejaculation at a younger age on average, with the difference becoming evident before age 14.

Summary: This article examines the impact of individual and societal gender role attitudes as well as societal father practices on nonresident father-child contact. The study finds that societal gender role attitudes and father practices are predictors of monthly contact between fathers and their children, while individual gender role attitudes are more important in predicting monthly contact between nonresident fathers and adolescent children.

Summary: The study found associations between father absence in pregnancy and during childhood with earlier pubertal development in girls, and father absence from late childhood with earlier pubertal development in boys. The paternal investment theory, psychosocial acceleration theory, and energetics theory did not explain these associations.

Summary: The study found that partial father absence may have particularly negative consequences for young adults' well-being, including higher levels of psychopathology and maternal overprotection, as well as lower levels of maternal care, romantic intimacy, commitment, and passion.

Summary: Denmark serves as an interesting case study for shared parenting, as it has high levels of father involvement and gender equality. However, the lack of data from Denmark in international debates can be attributed to researchers' preference for publishing in Danish. The study highlights reservations in Danish guidelines and practices regarding shared parenting and father involvement, which are not supported by the majority of scientists and available evidence. Therefore, societal transition towards increased shared parenting largely occurs voluntarily despite official laws and practices.

Summary: This study highlights the importance of comprehensive risk screening in family law services for separated parents. The findings suggest that patterns of modifiable risk can vary across different safety variables. The strongest predictors of safety risks include endorsement of another safety risk and parent report of the other parent not coping.

Summary: This study reports incidental observations of cooperative breeding behaviors in the endangered Hawaiian Stilt, including egg incubation by multiple adults and juveniles delaying dispersal to assist parents and siblings. These are the first published accounts of cooperative breeding in this subspecies and further investigation is warranted as it may improve the population viability of the endangered, endemic Hawaiian Stilt.

Summary: White-headed woodpeckers prefer and nest more successfully in higher elevation true fir forests. Congruence exists between habitat preferences and nest survival, particularly at the landscape scale, indicating adaptive selection. However, at the nest site scale, they may exhibit maladaptive habitat selection.

Summary: Although father love is important for the positive growth of the child, there is no reliable tool to assess the psychological absence of fathers. Thus, this study developed a scale called the father-love absence scale (FLAS) to measure adolescents' experiences of father-love absence from a psychological absence perspective. The FLAS demonstrated satisfactory reliability and validity, consisting of four factors: emotional absence, cognitive absence, behavioral absence, and volitional absence. It is concluded that the FLAS is a valuable tool for assessing father-love absence.

Summary: There has been a decrease in the age at menarche (AAM) among women from 26 ethnicities in Yunnan Province, China, born between 1965 and 2001, with a secular trend towards a younger AAM. The fastest rate of decline was observed in the Bai ethnicity, and consistent declining trends were seen across various economic patterns. Significant differences in the declining trends in AAM were observed along rural/urban lines.

Summary: This study aimed to assess the association between age at menarche (AAM) and multimorbidity and chronic diseases. Data from 8,294 female participants of the Azar Cohort Study were analyzed. The results showed that early menarche was associated with an increased risk of diabetes, obesity, and high waist-hip ratio (WHR), while late menarche was associated with a higher risk of hypertension, stroke, and diabetes, but a lower risk of multimorbidity, rheumatoid disease, obesity, abdominal obesity, and waist-to-hip ratio (WHtR). These findings highlight the significant health implications of changes in AAM.
