  • Investigating the unique nature of some exposures, - Examining the links between specific environmental factors and mental health conditions, - Conducting further research on the exposome-wide approach

    Mapping the exposome of mental health: exposome-wide association study of mental health outcomes among UK Biobank participants · 2025 · DOI

  • Current approaches often focus on single candidate exposures, overlooking the interconnected nature of exposures. The complexity of mental health phenotypes and the multiplicity of exposures pose a challenge that requires data-driven approaches. There is a need for a comprehensive mapping of the exposome of mental health to identify potentially modifiable targets to improve mental well-being.

  • The common origins of midlife diseases of despair and cardiometabolic risk are unclear. Prior work has described these trends, but the relationship between adolescent psychopathology and midlife diseases is not well understood. The study aims to address this gap by testing adolescent psychopathology as a potential common origin of midlife diseases of despair and cardiometabolic risk.

  • However, a comprehensive summary of worldwide human exposome research is lacking.

  • However, observational studies have given conflicting results on the association between smoking and placental weight.

  • Importance: It is not well understood if and how various social and environmental determinants of health (SEDoH) are associated with mortality rates related to cardio-kidney-metabolic syndrome (CKM) across the US.

    Social and Environmental Determinants of Health and Cardio-Kidney-Metabolic Syndrome–Related Mortality · 2024 · DOI

  • The paper identifies a gap in current governance approaches, which focus primarily on high-risk AI applications. The authors argue that the cumulative effects of low-risk AI applications are not addressed by current governance approaches. The paper proposes a theoretical framework to address this gap.

    The silent accumulation: AI as mental contaminant · 2026 · DOI

  • International cooperation for developing shared standards measuring and governing technological externalities requires specification of which externalities should be prioritized, how measurement standards would account for cultural differences in technology adoption, and enforcement mechanisms to prevent governance races-to-the-bottom.

    The silent accumulation: AI as mental contaminant · 2026 · DOI

  • Several limitations of the current study should be noted. First, despite using a longitudinal data, our mediation analyses remain correlational; causal inference would require experimental or quasi-experimental approaches. Second, all exposome measures used were assessed at baseline, so changes in environmental conditions over the follow-up period were not incorporated; future work incorporating time-varying exposome measures would capture a more dynamic illustration of exposome-brain-cognition relationships. Third, genomic contributions were not examined. Many exposome measures, particularly those related to the family environment such as parental mental health and household socioeconomic status, are known to be partly heritable and subject to intergenerational continuity (Kendler & Baker, 2007; Plomin & Bergeman, 1991).
