We also find that local ancestry informed eQTLs better colocalize with GWAS signals from studies of common complex traits in these populations. Using expression data from mismatched populations (like GTEx) as well as methods that ignore local ancestry leads to poorer functional characterization.

We even find thousands of eQTLs with opposing effects on gene regulation depending on the ancestry of the haplotype they reside on. These variants are likely to be missed by GWAS in admixed pops because their effects would cancel out.

Local ancestry modulates gene expression: shifting our understanding of genetic regulation and disease association within and across populations Genetic variants that influence transcript abundance, called expression quantitative trait loci (eQTL), are fundamental to understanding gene regulation and disease etiology. However, eQTL studies hav...

Ancestry underlying genes alters their genetic regulation in admixed populations. In Hispanic/Latinos and African Americans, ~50% of genes have >=1 eQTLs (~25% w/a causal eQTL) that differentially regulate expression given their underlying ancestry in our data. www.medrxiv.org/content/10.6...

Interbreeding between Neanderthals and modern humans was strongly sex biased Sex biases in admixture and other demographic processes are recurrent features throughout human evolution. For admixture between Neanderthals and anatomically modern humans (AMHs), sex bias has been p...

Many living people carry fragments of Neanderthal DNA, remnants of ancient interbreeding events, with uneven distribution across chromosomes. New work by @sarahtishkoff.bsky.social lab suggests patterns are most consistent with Neanderthal contribution to human populations being highly male biased.🧪

Flyer with information about the Genetics & Neurobiology of Language summer course at Cold Spring Harbor, held on July 27th to August 3rd 2026, applications due by April 10th 2026.
Instructors are Simon Fisher from the Max Planck Institute for Psycholinguistics, Netherlands, David Poeppel from New York University and Kate Watkins from the University of Oxford, UK.
The course description is as follows:
Why are children able to acquire highly sophisticated language abilities without needing to be taught? What are the neurobiological and neurophysiological processes that underpin human speech and language, and how do they go awry in developmental and acquired disorders? Which genetic factors contribute to this remarkable suite of human skills, and are there evolutionary precursors that we can study in other species?
This unique CSHL course, in its sixth iteration, addresses these core questions about the bases and origins of speech and language, through talks, interactive sessions, keynotes and debates, involving leading experts from a range of disciplines. It integrates the state-of-the-art from complementary perspectives, including development, cognitive models, neural basis, gene identification, functional genomics, model systems and comparative/evolutionary studies.
The invited speakers are:
Jennifer Below, Vanderbilt University
Elika Bergelson, Harvard University
Esti Blanco-Elorrieta, New York University
Jonathan Brennan, University of Michigan
Karen Emmorey, San Diego State University
Evelina Fedorenko, MIT
Julia Fischer, Cognitive Ethology Laboratory, Germany
Tecumseh Fitch, University of Vienna, Austria
Adeen Flinker, NYU Langone
Timothy Gentner, University of California, San Diego
Liberty Hamilton, UC Berkeley
Catherine Hobaiter, Wild Minds Lab, University of St. Andrews, UK
Sonja Vernes, The University of St. Andrews, UK
Sandra Waxman, Northwestern University

Common variation in meiosis genes shapes human recombination and aneuploidy - Nature Analysis of data from pre-implantation genetic testing sheds light on the genetic basis of meiotic-origin aneuploidy, the leading cause of human pregnancy loss, identifying common genetic variants ass...

Pregnancy loss is common in humans, and chromosomal abnormalities are the leading cause. Using genetic data from ~140,000 IVF embryos, we show that maternal variation in meiosis genes influences recombination and aneuploidy risk.

First-of-a-kind study shows encouraging data for trans kids who socially transition Ninety-four percent of participants in a new study stood firm in their trans identity after five years, and "detransitioning" is rare.

The name "Popular Science" doesn't mean we shift our coverage depending on public opinion. It means we cover relevant subjects that are rigorously researched, reliable, and grounded in reality.

And trans lives are grounded in reality.

We see y'all. No matter what.
