In 2018, Charles Murray challenged me to a bet: "We will understand IQ genetically—I think most of the picture will have been filled in by 2025—there will still be blanks—but we’ll know basically what’s going on." It's now 2025, and I claim a win. I write about it in The Atlantic.

Grateful to UVA Today for featuring our recent study! And big thanks to the creative mind behind this mildly creepy yet amazing graphic - who knew DNA methylation aging and twins could come together so seamlessly? news.virginia.edu/content/uva-...

Nice writeup on our paper that was recently published in Aging where we found second generation epigenetic clocks predicted cognitive decline in midlife in the Louisville Twins @ent3c.bsky.social @aging-us.bsky.social www.psypost.org/biological-a...

📈 #TrendingWithImpact: A new #researchpaper was #published on July 23, titled “Second generation DNA methylation age predicts cognitive change in midlife: the moderating role of childhood socioeconomic status.” 🔗 doi.org/10.18632/agi... #aging #quote #openaccess #publishing #twins #DNAMethylation

New paper with first author @sophiebell.bsky.social. We show that epigenetic clocks predict decline in IQ between adolescence and midlife, between and within twin pairs, and that the effect is stronger among people from low SES backgrounds. A Scarr-Rowe-adjacent effect. www.aging-us.com/advance

Another great BGA meeting in Atlanta.. glad to keep the lab tradition going @ent3c.bsky.social!

Major congrats to our colleagues at USC!! The 5ADCSI test for Alzheimer's disease blood biomarkers is now validated and published in Journal of Alzheimer's Disease. The 5ADCSI is a low-cost, sensitive assay capturing plasma amyloid-β, pTau, NfL, and GFAP: journals.sagepub.com/doi/10.1177/...
