Dietary quality is reported at the global, regional and national level across 185 countries. Though diet quality increased modestly since 1990 at the global level, in South Asia and Sub-Saharan Africa it did not improve. In some regions, children’s dietary quality is lower than that of adults.

Scourzic et al. show that germinal centre B cells display an enhanced ability to reprogram to induced pluripotent stem cells compared to mature B cells. This ability indicates their higher plasticity level and is T follicular helper cell-dependent.

Supersolids combine superfluid and crystal order and their response to external driving remains unclear. Now it is shown that, in a dipolar supersolid, rotation induces synchronization of the crystal motion via vortex nucleation.

In this pilot study, the authors detected specific brain regions that can be precisely targeted with transcranial magnetic stimulation to influence heart rate. The heart–brain coupling might serve as a readout to identify optimal individualized transcranial magnetic stimulation targets for depression.

JWST observations suggest that both pebbles and planetesimals played an important role in forming the giant exoplanet WASP-121 b beyond the H₂O ice line. They also indicate that strong vertical mixing likely drives the nightside atmospheric chemistry.

The authors introduce a method for modulating the multimodal nonlinear pulse propagation in fibers by controlled bending, achieving a tunable broadband high-peak-power femtosecond light source that could empower nonlinear imaging and spectroscopy.

Photochemical modelling suggests that H₂ outgassing from crustal hydration could have supported transient warming episodes on early Mars in a CO₂-rich atmosphere with abrupt transitions to cold climate states in a CO-rich atmosphere.

Reproduction in numerous marine organisms is timed to specific moon phases, but the mechanisms for sensing moon phases are incompletely understood. Here the authors report that an ancient, light-sensitive protein L-Cryptochrome in a marine bristle worm can discriminate between sun- and moonlight, enabling the animals to properly decode moon phases.

This study uses multispecies modelling to show that the management of a coral predator, the crown-of-thorns starfish, could help corals recover following bleaching events. They show that management was most effective when heat stress severity for corals was low to moderate, when corals had lower heat sensitivity and when the recruitment rate of starfish was high.

Haploid genetic screening of cells under different types of mitochondrial perturbation shows that a pathway involving OMA1, DELE1 and the eIF2α kinase HRI communicates mitochondrial stress to the cytosol to trigger the integrated stress response.

Targeting self-renewing cancer cells without deleterious side effects in normal tissues has proven challenging. Here, the authors show that the well-tolerated HDAC inhibitor Quisinostat safely inhibits tumor maintenance and disease relapse by restoring high levels of histone H1.0.

Epileptic seizures need better treatments. Here, the authors show that seizure intensity is predicted and controlled by pre-seizure activity of hypothalamic orexin cells, and can be reduced by a hypothalamic deep brain stimulation.

Genotype and exome sequencing of 150,000 participants and whole-genome sequencing of 9,950 selected individuals recruited into the Mexico City Prospective Study constitute a valuable, publicly available resource of non-European sequencing data.

Analyses of 2,658 whole genomes across 38 types of cancer identify the contribution of non-coding point mutations and structural variants to driving cancer.

In this Expert Recommendation, Lauder and colleagues compare the latest European Society of Cardiology and European Society of Hypertension guidelines on hypertension, highlight the key consensus recommendations and compare differing approaches to definitions, classification, diagnosis and treatment, with the aim to help health-care professionals in their decision-making to improve the management of hypertension.

Long-read sequencing is useful in determining exon-connectivity of full-length mRNA isoforms. Here, by long-read nanopore sequencing, the authors report that intron retention is downregulated in SF3B1 mutant chronic lymphocytic leukemia cells than normal B cells.

The dayside thermal emission spectrum and brightness temperature map of the ultra-hot Jupiter WASP-18b obtained from the NIRISS instrument on the JWST showed water emission features, an atmosphere consistent with solar metallicity, as well as a steep and symmetrical decrease in temperature towards the nightside.

Isotopic labelling and multi-omics experiments conducted in Biosphere 2 show how dry conditions reprogramme microbial metabolism.

The authors studied the function of a PIN gene in a filamentous charophyte green alga (Klebsormidium flaccidum). They found that the plasma membrane auxin efflux function is an early trait that emerged before divergence between algae and land plants.

Many recent studies have explored the response of magnetic systems to circularly polarised light. To achieve this, typically experiments use a birefringent crystal. Here, Yang et al show that any small error in the alignment of the crystal can result in a beam shift, and this shift can lead to spurious signals similar yet unrelated to the electron spin.

The origin of the genus Homo is debated. Here, the authors investigate the morphology of the H. habilis enamel-dentine junction using a sample of 911 hominin and extant ape teeth, finding that H. habilis has more in common with Australopithecus than later members of the genus Homo.

Dam1 is a component of the microtubule-binding DASH complex. Artificial recruitment of Dam1 to yeast mini-chromosomes can compete with endogenous kinetochores for microtubule binding and rescue chromosome segregation in the absence of centromeres.

Phase-resolved mid-infrared observations from JWST of the hot gas giant WASP-43b detect a day–night difference of 659 ± 19 K. Comparison with climate models shows that the observations are compatible with cloudy skies, at least on the nightside, and the lack of methane detection suggests the presence of disequilibrium chemistry.

Cryogenic electron microscopy structures of the Synechocystis phycobilisome—alone and bound with orange carotenoid protein—reveal detailed information regarding the biophysical basis of the control of cyanobacterial light harvesting.

Kedzierska et al. report an association between low production of receptor-binding domain antibodies after mRNA vaccination and altered glycosylation of IgG before vaccination in people with comorbidities, and show that this condition disproportionately affects Australia’s First Nations peoples because of the high burden of comorbidities in this population.

The authors present the genome sequence of a >45,000-year-old female Homo sapiens individual from the site of Zlatý kůň, Czechia. Although radiometric dating of the human remains was inconclusive, the authors were able to use molecular methods to demonstrate that she was probably among the earliest Eurasian inhabitants following expansion out of Africa.

In this Review, a group of experts in fragile X syndrome analyses why the considerable drug development effort based on robust preclinical findings describing the mechanisms underlying this neurodevelopmental disorder has failed to translate into effective treatment and offers possible solutions to improve clinical trial design and therapeutic approaches.

This Perspective discusses the need for standards that allow for comparisons of quantitative physiological features in microphysiological systems and humans.

A pair of SHIP box motifs identified within the Exo1 nuclease mediate interactions with Msh2 during DNA mismatch repair and define potential new Msh2-binding partners in yeast and human cells.

In vitro, in vivo and in silico studies identify the transcriptional repressor ZBTB18 as a negative regulator of tumor associated macrophage recruitment and of their tumor promoting phenotype in glioblastoma

Beta subunits of GABAA receptors are unexpectedly shown to form homomeric proton gated ion channels attributable to a single histidine residue.

Lester and colleagues use faecal samples and genetic analyses to investigate the genetic connectivity across chimpanzees. Their results indicate that the global pattern of genetic diversity in chimpanzees is largely characterized by a pattern of isolation by distance with several isolated populations exhibiting strong local differentiation.
