Vast amounts of DNA methylation data have paved the way for epigenetic clocks to significantly advance aging research; however, generative artificial intelligence (AI) may have now laid the foundation for more transformative insights into DNA methylation. Two preprints report the application of transformer architecture to develop “foundation” or large AI models trained on vast DNA […]

DNA Methylation and Chromatin Map of the Developing Brain Revealed with Single-Cell Multiomics
Maps can tell you where to go and what landmarks you’ll find along the way. In the same way, a new multiomic map describes how DNA methylation and 3D chromatin conformation changes in the prefrontal cortex and hippocampus as the human brain develops. The map could help researchers determine the heritability of neuropsychiatric conditions, such […]
Psychosis Moderates the Association Between Cannabis Use and DNA Methylation
Analyzing the DNA methylation alterations induced by cannabis use has provided a wealth of evidence of potential harms, with recent studies focusing on neurodevelopmental problems after prenatal exposure, increased risk of adverse health outcomes, and accelerated epigenetic aging. Now, a study reports the first epigenome-wide association study (EWAS) exploring the interplay between cannabis use, DNA […]
Children Prenatally Exposed to Cannabis Have Altered DNA Methylation
As more states legalize and decriminalize cannabis, more questions are being raised about its effects, especially on pregnancy. Now, a clear-thinking team sees through the haze and shows that maternal cannabis use during pregnancy is associated with epigenome-wide differential DNA methylation in the blood of exposed children, especially in genes involved in neurodevelopment. Studies have shown […]
Genome-Wide DNA Methylation Changes from Vaping and Smoking Have Striking Similarities
Vaping has been touted as a safer alternative to smoking, but some recent studies are showing that the biological effects have similarities. Now, a team clears the air and reports that DNA methylation changes in vapers’ oral cells resemble those found in smokers, which suggests that vaping could have comparable long-term health effects. Smoke gets in […]
