Alzheimer's disease cases are projected to double within the next two decades. Research funding was just cut in half. Needless to say, the math ain't mathing.

Packed first day at #INS2026inPhiladelphia! Loved sharing our Lifespan Cognitive Health Risk Score with a room full of neuropsychologists 🧠 @ent3c.bsky.social Then caught Abeera Ahmad presenting our poster on concordance between amyloid positivity + neuropsych testing @ins-slc.bsky.social

(1/4) Thrilled to share our new paper out now in @geronsociety.bsky.social Journals of Gerontology. The association between birthweight and cognitive ability declined exponentially across the lifespan. A longitudinal twin study helped us unpack why... academic.oup.com/psychsocgero...

Another intriguing Atlantic read from Eric Turkheimer @ent3c.bsky.social and Paige Harden @kph3k.bsky.social! "We can add three and two to make five, but we cannot add scientific breakthroughs to bigotry and arrive at a tidy, incontrovertible sum. One deed sits stubbornly beside the other."

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.

Your Genes Are Simply Not Enough to Explain How Smart You Are
Seven years ago, I took a bet with Charles Murray about whether we’d basically understand the genetics of intelligence by now.

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-...

UVA study of identical twins links faster aging to memory decline
Researcher Sophie Bell and professor Eric Turkheimer identified how genetics, environment and biology combine to affect cognitive health.

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
Graph illustrating interaction effect whereby epigenetic clocks predict IQ decline more strongly in twins from low SES backgrounds.
