How do bacteria deal with double costs? And how costly are unusual levels of mistranslation anyway? In short - antibiotics are more of an issue than less/more mistranslation, but the latter changes how populations deal with antibiotics. For the long story, check out our new paper!

The Black Death was history's worst documented demographic disaster. New research shows it was also a bizarre anomaly, the unlikely result of volcanic eruptions, multiple consecutive poor harvests in Italy, a war between Genoa, Venice and the Mongols, AND a Black Sea plague outbreak. @science.org

Genetic architectures of #ComplexTraits vary widely. @yuvalsim.bsky.social @jkpritch.bsky.social @gs2747.bsky.social &co show these diffs arise from mutational target size & heritability per site; when controlled for, all tested traits have similar architectures @plosbiology.org 🧪 plos.io/47mZXqT
 Heritability and target size underlie differences between trait architectures:

examples for three traits. Top: Height (blue) and platelet crit (red) have the same heritability per site h2/L, but height has a much higher mutational target size L. This results in many more hits for height (1533) than for platelet crit (648) (2 left panels). However, the marginal distributions of effect sizes, MAFs, and z-scores of hits are nearly identical for the two traits (3 right panels). Middle: Height (blue) and FEV1 (gold) differ in h2/L, but have similar L. Consequently, the joint distribution of z-scores and MAFs of their hits are markedly different (2 left panels), as are the marginal distributions of hit effect sizes, MAFs and z-scores (right). Bottom: After scaling by their respective , and imposing the more stringent scaled significance threshold (corresponding to FEV1) for both traits, the joint distribution of z-scores and MAFs of their hits (2 left panels) and the corresponding marginal distributions (3 right panels) are highly similar.
