Does Education Pay in Urban China? Estimating Returns to Education Using Twins [PDF]

open access: yes
This paper empirically estimates the returns to education using twins data that the authors collected from urban China. Our ordinary least-squares estimate shows that one year of schooling increases an individual¡¦s earnings by 8.4 percent. However, once

Genome‐Wide 5‐Methylcytosine and 5‐Hydroxymethylcytosine Signatures Analysis of Plasma Cell‐Free DNA in Schizophrenia

open access: yesMedComm, Volume 6, Issue 8, August 2025.
We performed cfDNA 5‐methylcytosine (5mC) and 5‐hydroxymethylcytosine (5hmC) sequencing of plasma samples from 66 individuals with SCZ and 77 healthy controls (HC). We identified differentially 5mC methylated regions (DMRs) and differentially 5hmC hydroxymethylated regions (DhMRs) that showed distinct patterns between SCZ and control samples.

Multi‐Omic Associations of Epigenetic Age Acceleration Are Heterogeneously Shaped by Genetic and Environmental Influences

open access: yesAging Cell, Volume 24, Issue 8, August 2025.
The connections between epigenetic age acceleration (EAA) and the multi‐ome, as well as the extent to which these connections are driven by genetic and environmental factors, remain underexplored. We identified blood proteins, metabolites, and exposures associated with EAA in young adults and, using twin study designs, show that these associations are ...

Brain DNA Methylation Age, Lifestyle Factors and Dementia in the Swedish Twin Registry

open access: yesAging Cell, Volume 24, Issue 8, August 2025.
DNA methylation age (DNAmAge) uses molecular information to quantify biological ageing. We assessed brain‐specific DNAmAge among Swedish Twin Registry participants, revealing adverse associations with smoking and protective associations with education. Dementia outcomes were not clearly associated with brain DNAmAge.

CDK13‐Related Disorder: Novel Insights From A Series of 27 Cases and Recommendations for Clinical Management

open access: yesClinical Genetics, Volume 108, Issue 2, Page 146-155, August 2025.
This report described 27 novel subject with CDK13‐related disorders. Collecting the clinical and radiological data, we better define the phenotypic spectrum of this condition and we suggest a comprehensive clinical management. ABSTRACT In 2016, Sifrim and colleagues described the first group of patients carrying heterozygous pathogenic variants in ...
