Genomic history of early dogs in Europe

Nature, Published online: 25 March 2026; doi:10.1038/s41586-026-10112-7

Genome-wide analysis shows European dogs existed by 14,200 years ago, were already genetically distinct, received less Neolithic Southwest Asian admixture than humans did and contributed substantially to later European dogs.

Exposed phosphatidylserine is an inhibitory molecule in T cell exhaustion

Nature, Published online: 25 March 2026; doi:10.1038/s41586-026-10266-4

Insights into the mechanism by which phosphatidylserine functions as a non-classical inhibitory molecule during T cell exhaustion, and how phosphatidylserine-targeting antibodies enhance T cell responses are explored.

Oxygen supply through the tracheolar–muscle system does not constrain insect gigantism

Nature, Published online: 25 March 2026; doi:10.1038/s41586-026-10291-3

New evidence suggests that diffusive oxygen transport through the tracheolar–muscle system is not the limiting factor on insect body size.

Superluminal correlations in ensembles of optical phase singularities

Nature, Published online: 25 March 2026; doi:10.1038/s41586-026-10209-z

Ultrafast electron imaging shows full phase-space dynamics of optical singularities, which can reach superluminal velocities before annihilation and break the particle-like analogy of topological defects.
