The Impact of Adverse Childhood Experiences on the Development of Adolescent Risk-Taking: The Mediating Effect of Self-Control and Moderating Effect of Genetic Variations.
J Youth Adolesc
January 2025
Research Center of Adolescent Psychology and Behavior, School of Education, Guangzhou University, Guangzhou, China.
Risk-taking is a concerning yet prevalent issue during adolescence and can be life-threatening. Examining its etiological sources and evolving pathways helps inform strategies to mitigate adolescents' risk-taking behavior. Studies have found that unfavorable environmental factors, such as adverse childhood experiences (ACEs), are associated with momentary levels of risk-taking in adolescents, but little is known about whether ACEs shape the developmental trajectory of risk-taking.

Identifying populations at highest risk from climate change is a critical component of conservation efforts. However, vulnerability assessments are usually applied at the species level, even though intraspecific variation in exposure, sensitivity and adaptive capacity play a crucial role in determining vulnerability. Genomic data can inform intraspecific vulnerability by identifying signatures of local adaptation that reflect population-level variation in sensitivity and adaptive capacity.

University of Bologna-Alma Mater Studiorum, Department of Quality of Life Sciences, Bologna, Italy.
Background: Understanding the impact of caffeine intake on body composition is a topic of growing research interest. The article "Association Between Caffeine Intake and Fat-Free Mass Index: A Retrospective Cohort Study" by Tian et al. explored this relationship, highlighting a positive correlation between caffeine consumption and fat-free mass index (FFMI).

Background: Disease comorbidities and longer-term complications, arising from biologically related associations across phenotypes, can lead to increased risk of severe health outcomes. Given that many diseases exhibit sex-specific differences in their genetics, our objective was to determine whether genotype-by-sex (GxS) interactions similarly influence cross-phenotype associations. Through comparison of sex-stratified disease-disease networks (DDNs)-where nodes represent diseases and edges represent their relationships-we investigate sex differences in patterns of polygenicity and pleiotropy between diseases.

Mol Cell
January 2025
Max Planck Institute for Multidisciplinary Sciences, Göttingen, Germany. Electronic address:
By building synthetic regulatory landscapes, Jensen et al. and Thomas et al. demonstrate in this issue of Molecular Cell that gene expression levels strongly depend on the genomic distance between enhancers and promoters and that enhancer cooperation can compensate for reduced enhancer activity over large genomic distances.
