HIV transmissions into intervention communities from control communities in the Botswana/Ya Tsie trial were similar to the reverse at baseline, and 10 times more common post-baseline, concordant with a predicted benefit of a universal test-and-treat HIV prevention intervention.

In baboon gut microbiota, most pairwise correlations in bacterial abundances are weak and negative, and bacterial correlation patterns are largely shared across hosts, rather than personalized to each hosts.

The nearly universal nature of scaled cell shape variability in an epithelial monolayer is unavoidable, irrespective of health or disease, as it comes from a mathematical property.

A cross-cultural study of reading acquisition and reading irmpairment reveals the invariance of the neural correlates of reading across cultures.

Cortices from 11 primate species share the same archetypal fractal shape, indicating a universal mechanism for primate and mammalian cortical folding, and suggesting novel shape biomarkers for brains.

Ancient protein domains remain shaped by amino acid availability during early life, while young animal proteins are shaped by a need for high intrinsic structural disorder.

A simple and robust statistical test for neuronal stimulus response, that outperforms PSTH-based approaches such as t-tests and ANOVAs.

Several previously proposed cell-surface receptors for hantaviruses could be deleted in endothelial cells with little or no effect on infection, indicating that critical hantavirus entry factors remain undiscovered.

Relatively few genes have evolved vertically from the last universal common ancestor to modern prokaryotes, and phylogenetic analysis of these genes demonstrates a great genetic distance between Archaea and Bacteria.

Proteins evolve more intrinsic structural disorder under more effective selection, with selection assessed via a novel metric of codon adaptation.
