Endogenous virus sequences in the genomes of modern mammals reveal the global spread of an ancient virus lineage, including frequent interspecies transmission, adaptation, and emergence spanning several million years of mammalian evolution

A computer model built on insights gained from comprehensive experimental analysis reveals mechanisms of blood stem cell regulation.

A rigorous and transparent evaluation of mesenchymal stem cell therapy for sepsis suggests it may be efficacious, although the strength of these findings is tempered by threats to validity in the studies that were included.

Recent advances in technology now make it possible to carry out biomedical research on animals living in the wild, or captive animals living in naturalistic conditions.

Cytokinin-dependent manipulation of plant metabolism is a strategy employed not only by gallers and leaf-miners but also by a free-living insect, Tupiocoris notatus, which directly transfers cytokinins at feeding sites to manipulate its host plant.

The rules of biomechanics consistently influence the tempo (rate) and mode (pattern) of evolution across four-bar linkage systems in animals.

Genetic and epigenetic editing experiments establish causal links between transposon-derived enhancers and gene regulation in mouse embryonic and extraembryonic lineages.

Natural selection shaped CHC22 clathrin genetic variation in humans with different diets and potentially influenced the human insulin response.

The rat is much more than a simple model, and a better appreciation of the natural history of wild rats would increase its value as a research organism.

Purinergic keratinocyte-to-sensory neuron signaling is a ubiquitous amplification mechanism that is required for normal mechanical, cold, and heat sensation in vivo.
