Single-stranded DNA annealing is driven by RAD52 open rings in association with RPA.

Using complementary multiplicity-edited ¹³C nuclear magnetic resonance spectra, oxidative dearomatization is shown to be a key driver for generating structural diversity during processing of dissolved organic matter and the data also suggest high abundance of OC_qC₃ units.

Patagia—the mammalian gliding membrane—repeatedly originated through a process of convergent genomic evolution, whereby the regulation of Emx2 was altered by distinct cis-regulatory elements in independently evolved species.

Phylogenomic analysis of 7,923 angiosperm species using a standardized set of 353 nuclear genes produced an angiosperm tree of life dated with 200 fossil calibrations, providing key insights into evolutionary relationships and diversification.

Sea-based optical clocks combining a molecular iodine spectrometer, fibre frequency comb and electronics for monitoring and control demonstrate high precision in a smaller volume than active hydrogen masers.

Prostaglandin E2 from the tumour microenvironment impairs interleukin-2 sensing by tumour-infiltrating lymphocytes, restricting proliferative response and promoting T cell death via metabolic impairment and ferroptosis. 

Analysis of ancient DNA from 424 individuals in the Avar period, from the sixth to the ninth century AD, reveals population movement from the steppe and the prolonged existence of a steppe nomadic descent system centred around patrilineality and female exogamy in central Europe.

The Human Muscle Ageing Cell Atlas provides a series of integrated cellular and molecular explanations for sarcopenia and frailty development in advanced ages.

A screen utilizing an environmental DNA library in Escherichia coli is used to identify Brig1, a previously unknown anti-phage defence system with homologues across distinct clades of bacteria.

Genomic studies of Heliconius butterflies provide evidence that Heliconius elevatus is a hybrid species, and that its speciation was driven by introgression of traits from Heliconius melpomene into the other parent, an ancestor of Heliconius pardalinus.

Methane emission from a very cool brown dwarf, perhaps arising from an aurora, has been detected in James Webb Space Telescope observations.

We propose a model for a sequential, multistep activation mechanism of metabotropic glutamate receptor subtype 5, including a series of structures in lipid nanodiscs, from inactive to fully active, with agonist-bound intermediate states.

Analysis of projected sub-national damages from temperature and precipitation show an income reduction of 19% of the world economy within the next 26 years independent of future emission choices.

Challenging the belief that sympathetic ganglia are an innovation of jawed vertebrates, a study reports the presence of sympathetic neurons in an extant jawless vertebrate, the sea lamprey Petromyzon marinus.

Using observations of double-difference relocated earthquakes in a local three-dimensional velocity model for Ecuador, a detailed image of seismicity is created, forming the base for more realistic models of earthquake rupture, slip and hazard in subduction zones.

Analysis of a global dataset reveals spatiotemporal patterns of marine plankton and their biogeographical responses during climatic and environmental changes across the Cenozoic era.

Hippocampal theta–gamma phase–amplitude coupling integrates cognitive control and working memory storage across brain areas in humans.

A study investigates subcellular, single-cell and network-level comunication within the astrocyte network in response to the two major neurotransmitter inputs.

Near-field radiative heat transfer between two coplanar silicon carbide membranes in close proximity is enhanced by the electromagnetic corner and edge modes.
