Single-cell transcriptomic profiling of fetal liver, skin, kidney and yolk sac reveals the differentiation trajectories of human haematopoietic stem cells and multipotent progenitors, which are validated to produce an integrated map of fetal liver haematopoiesis.

Tarpey et al. carry out a large-scale systematic sequencing of the majority of X-chromosome coding exons from 208 families with multiple individuals with mental retardation and a pattern of transmission compatible with X linkage in order to identify XLMR-causative mutations. They find several mutations that appear to be causative in loci already known to be involved in XLMR, as well as new data about those loci, and make inferences about the role of the different classes of variants in these diseases.

Compact exoplanetary systems frequently experience spin–orbit coupling driven by secular resonances, which can shape their architecture, allowing the planet to maintain a large obliquity and inducing the piling up of planets just wide of the first-order resonance.

Defined levels of SARS-CoV-2-specific binding and neutralizing antibodies elicited by the COVID-19 vaccine ChAdOx1 nCoV-19 are identified as correlates of protection against symptomatic infection.

Authors of some of the most highly cited Nature Biotechnology papers that describe research tools discuss their work and challenges for their fields.

Not everyone with a fatty liver goes on to develop more advanced disease. Understanding what triggers the progression could lead to better treatments.

The JWST MIRI transmission spectrum of WASP-107b, a transiting planet with Neptune-like mass and Jupiter-like radius, shows observations of sulfur dioxide and silicate clouds but no methane in its atmosphere, providing evidence of disequilibrium chemistry and active photochemistry.

Observations from the JWST MIRI showed the detection of ¹⁴NH₃ and ¹⁵NH₃ isotopologues in the atmosphere of a cool brown dwarf, along with a ¹⁴N/¹⁵N value consistent with star-like formation by gravitational collapse.

During embryogenesis, the cytoplasmic protein Myomarker (MYMK) mediates muscle fibre formation by fusion of myoblasts. Here, the authors identify autosomal recessive mutations in MYMK that cause Carey-Fineman-Ziter syndrome in humans, and model the disease variants in zebrafish.

The CNV analysis group of the Psychiatric Genomic Consortium analyzes a large schizophrenia cohort to examine genomic copy number variants (CNVs) and disease risk. They find an enrichment of CNV burden in cases versus controls and identify 8 genome-wide significant loci as well as novel suggestive loci conferring either risk or protection to schizophrenia.

The successful reprogramming of adult cells into induced pluripotent stem (iPS) cells without viral vectors adds to the excitement about the application of iPS cells in drug discovery and development.

Relatives of patients with amyotrophic lateral sclerosis have an unexpectedly high incidence of schizophrenia. Here, the authors show a genetic link between the two conditions, suggesting shared neurobiological mechanisms.

Previous studies identified an association between the 2q35 locus and breast cancer. Here, the authors show that a SNP at 2q35, rs4442975, is associated with oestrogen receptor positive disease and suggest that this effect is mediated through the downregulation of a known breast cancer gene, IGFBP5.

Short tutorials can help researchers to sharpen skills, and longer courses can provide a way to deepen knowledge.

Schizophrenia is a highly heritable genetic disorder, however, identification of specific genetic risk variants has proven difficult because of its complex polygenic nature—a large multi-stage genome-wide association study identifies 128 independent associations in over 100 loci (83 of which are new); key findings include identification of genes involved in glutamergic neurotransmission and support for a link between the immune system and schizophrenia.

Writing science books for the public is rewarding, but can take a lot of time — and financial gain is uncertain.

The hypothalamus controls homeostatic functions such as metabolism and sleep, which undergo age-related changes. Here the authors perform single-nuclei transcriptomics profiling of young and old hypothalamus from female mice and describe changes in gene expression with age, in particular increased expression of the X inactivation gene Xist.

Infants born to obese mothers have altered microbiome and increased risk of obesity and NAFLD. Here the authors establish causality by showing that maternal obesity-shaped infant gut microbiome induces macrophage dysfunction, inflammation, and diet-induced metabolic disease in germ-free mice.
