Phylogenetic evidence suggests that the majority of HIV infections occurring in the UNAIDS Fast-track city Amsterdam continue to have an Amsterdam resident as source, indicating that the majority of HIV infections in Amsterdam could be prevented through city-level interventions.

A large-scale experiment demonstrates sex differences in cooperation and competition that can explain group size variation in ostriches.

A large-scale phylogenetic inference of the ribonucleotide reductase family reveals a new distinct clade with implications on how nature adapted to environmental changes.

Experimental manipulations of social groups of ostriches show that the benefits of cooperative parental care for females, and the costs of sexual competition for males, lead to sex differences in optimal group sizes.

Mountain gorillas, who live in close-knit social groups with siblings and non-siblings of both sexes throughout their lives, show distinct behavioral biases towards maternal versus paternal kin.

A relative of the tur, wild goat species now endemic to the Caucasus, lived at least 14,000 years ago in southern Turkey.

Combining clinical and genetic data can improve the effectiveness of virus tracking with the aim of reducing the number of HIV cases by 2030.

Diffusion but not advection becomes increasingly challenging for gas transport across insect spiracles as body size increases.

The absence of negative selection observed in most cancer genomes can be explained by the intrinsic genome-wide linkage in somatic evolution and creates a substantial proteotoxic load.

In wild bonobos, sibling birth induced a sudden increase in urinary cortisol levels in the older offspring, a physiological response that occurred in all subjects and was independent of their age.
