Some threads and notable studies I've tweeted are nested under this pinned tweet.

"This study shows that sexual orientation is reflected in brain structure characteristics and that these differ between the sexes." https://t.co/TVb2nx7MJw

"Regions in the precentral gyrus, precuneus and the prefrontal cortex were significantly informative for distinguishing heterosexual from homosexual participants."

"We demonstrate for the first time that sexual orientation is reflected in specific patterns of RSFC, which enable personalized, brain-based predictions of this highly complex human trait."

A machine learning approach using resting-state functional connectivity had an average accuracy of 92% in predicting sexual orientation. https://t.co/qFcECgg8RM

5-year study of 70,000 English children found that the correlation between IQ at age 11 and educational achievement in 25 academic subjects at age 16 was 0.81. https://t.co/pVT7VK9D3l

Robert Plomin: "Average differences between cultures are not necessarily 'cultural' — they might be due to genetic differences between cultures.” https://t.co/wGntRlKoOS

"Here the Human Pangenome Reference Consortium presents a first draft of the human pangenome reference... We assembled 47 fully phased diploid assemblies from genomes selected to represent global genetic diversity." https://t.co/sjOgZGbxTS

"We identified 53 [SNPs] associated with a latent trait... approximating the group factor of quantitative ability... [and we found] positive associations with STEM occupations." https://t.co/4lm6ftBDxZ

"We could not analyse EA and cognitive traits because of ethics restrictions. However, we emphasise that additional research using the within-family is needed to inform ongoing debates about the relative importance of direct and indirect genetic effects for such traits."

New preprint: "We analyse approximately 500,000 sibling pairs with diverse ancestries... [we find] substantial genetic variation underlies complex traits... [and that estimates are] larger than has been accounted for by GWAS to date." https://t.co/yapwhCyXWa

"Increasingly sophisticated analysis of genetic material made possible by technological advances shows that virtually everyone came from somewhere else, and everyone’s genetic background shows a mix from different waves of migration that washed over the globe."

Research conducted in 2015 "showed just a dozen places in the genome that had changed over the last 8,000 years in a way that might indicate natural selection." But new research conducted by Reich "found almost 500 significant changes."

"[Harvard geneticist David] Reich said it had been believed that natural selection was minimal among humans for the last 10,000 years... [but] Reich now believes Europe, at least, is in a period of accelerated selection that began 5,000 years ago." https://t.co/VY5hzG8ung

Meta-analysis: "We conclude that apparent effects of growth mindset interventions on academic achievement are likely attributable to inadequate study design, reporting flaws, and bias." https://t.co/Afd7qAQYaL

A new Norwegian study finds that diagnoses for all psychological disorders except bipolar disorder and affective psychosis are most common in the lowest-IQ range and least common in the highest-IQ range. https://t.co/54oviUyvto

HEALTH IS WEALTH Magnesium Health Benefits Magnesium is an essential mineral that acts as a cofactor in over 300 enzyme systems, supporting processes like protein synthesis, muscle and nerve function, blood glucose control, blood pressure regulation, energy production, and

"Genetic and environmental influences on childhood antisocial and aggressive behavior (ASB) during childhood... revealed a common ASB factor across informants that was strongly heritable (heritability was .96)." https://t.co/6zR2WlSsEC

3/ "We show that... genetic predispositions that derive from post-Neolithic admixture events act as a source of variability and as potential confounders in Europe as a whole."

2/ Such structure is regarded as a confounder in GWAS and follow-up studies... Heart rate, platelet count... and many other traits show stratification similar to height and pigmentation traits, likely targets of selection and divergence across ancestral groups."

1/ "The genetic structure in Europe was mostly shaped by admixture between the Western Hunter-Gatherers, Early European Farmers and Steppe Bronze Age ancestral components." https://t.co/kydzOcJ87E
