A detailed parcellation (map) of the human cerebral cortex has been obtained by integrating multi-modal imaging data, including functional magnetic resonance imaging (fMRI), and the resulting freely available resources will enable detailed comparative studies of the human brain in health, ageing and disease.

Progesterones, oestrogens and their receptors (PR, ERα and ERβ) are essential in normal breast development and homeostasis, as well as in breast cancer; here it is shown that PR controls ERα function by redirecting where ERα binds to the chromatin, acting as a proliferative brake in ERα⁺ breast tumours.

Analysis of mutations in MC4R and associated anthropometric phenotypes in the ALSPAC birth cohort reveals a prevalence of heterozygous loss of function of 0.30% and provides evidence that these mutations are associated with substantial excess adiposity in early life.

Using whole-genome data for single-nucleotide polymorphism and results from genome-wide association studies, the authors show that people’s preference for pairing with those with similar phenotypic traits has genetic causes and consequences.

Iceberg-trajectory models along with multi-proxy evidence from sediment cores from the Indian Ocean show that northward shifts in Antarctic iceberg melt redistributed freshwater in the Southern Ocean during the Pleistocene.

Inhibitors of α_vβ₃ and α_vβ₅ integrins have previously been shown to inhibit tumor angiogenesis and growth and have entered human clinical trials. Andrew Reynolds and his coworkers now show that low (nanomolar) concentrations of these inhibitors can unexpectedly promote VEGF-dependent tumor angiogenesis and growth in vivo. Such effects could compromise the anticancer efficacy of these agents in humans.

The Cancer Genome Atlas consortium reports on their genome-wide characterization of somatic alterations in colorectal cancer; in addition to revealing a remarkably consistent pattern of genomic alteration, with 24 genes being significantly mutated, the study identifies new targets for therapeutic intervention and suggests an important role for MYC-directed transcriptional activation and repression.

The Ups/PRELI family mediates intramitochondrial lipid distribution and synthesis by shuttling phospholipids between both mitochondrial membranes. Here the authors combine X-ray crystallography, MD simulations and yeast genetic screens and identify residues that are important for Ups/PRELI lipid specificity and reveal a dual lipid recognition mechanism in Ups/PRELI family members.

The heterogeneity of androgen receptor (AR) gene alterations across metastases in prostate cancer remains unresolved. Here, the authors characterise AR genomic complexity across spatially separated lethal metastases from 10 prostate cancer patients and investigate how AR alterations evolve.

A new drug inhibits the adverse effects of C-reactive protein, a blood protein that has been shown to exacerbate damage in the heart and brain after blockage of the blood supply.

Current multiple sclerosis treatments focus on prevention of immune attack on oligodendrocytes and myelin. Here the authors show a different strategy to ameliorate disease in several mouse models, protecting oligodendrocytes from inflammation-induced death with an FDA-approved drug, guanabenz.

The incidence of esophageal squamous cell carcinoma varies significantly across different geographical regions. Mutational signature analysis of tumors sampled from high- and low-incidence areas suggests that these variations may not be explained by mutagenic exposures.

Amyotrophic Lateral Sclerosis (ALS) is highly heritable but the mechanisms of sporadic ALS are not fully understood. In this study, the authors identify drivers of variation and disease-relevant changes in the epigenomic profile of iPSC-derived motor neuron lines generated from ALS patients and healthy controls as part of the Answer ALS program.

Fanconi anemia is a rare disease caused by defective DNA interstrand crosslink repair. Here the authors observe that USP48 deficiencies reduce chromosomal instability in FA-defective cells, suggesting it might be a potential therapeutic target.

Application of pathogen-specific double-stranded RNA (dsRNA) was proposed as an approach against plant viruses. However, the instability of dsRNA hampers its application. Now, a study has used clay nanosheets to deliver dsRNA and obtain sustained protection against viruses.

Analysis of peatland carbon accumulation over the last millennium and its association with global-scale climate space indicates an ongoing carbon sink into the future, but with decreasing strength as conditions warm.

Two high-quality nanopore genome assemblies of Brassica nigra are reported, one of which has particularly high contiguity with a contig N50 of 17.1 Mb, allowing localization of active centromeres and reconstruction of the ancestral Brassica genome.

Large films of aligned and closely packed single-walled carbon nanotubes can be prepared through slow vacuum filtration, and used to create terahertz polarizers, thin-film transistors, polarized light emission devices, and polarization-sensitive detectors.

In a dose-escalation study of the COVID-19 RNA vaccine BNT162b1 in 45 healthy adults, RBD-binding IgG concentrations and SARS-CoV-2 neutralizing titres in sera increased with dose level and after a second vaccine dose.

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.

Fanconi anemia is a complex disease affecting multiple DNA repair proteins that resolve DNA crosslinks which can block vital processes. Here the authors use parallel genome-wide screens that identify the BLM helicase complex as a suppressor of Fanconi anemia phenotypes.

Sequencing of over 600 genes in a large collection of lung adenocarcinoma samples provides an overview of somatic mutations and signalling pathways altered in cancer genes in this tumour type.

Molecular profiling of breast cancer in non-Caucasian populations remains underexplored. Here the authors report a high prevalence of HER2-subtypes and enriched immune score with improved survival and higher rates of TP53 somatic mutations with poorer survival in ER+ tumours in a Malaysian cohort.

Wildebeest, particularly during their long migrations under hot arid conditions, gain a considerable increase in range as a result of having highly efficient muscles.

For many neurodevelopmental disorder (NDD) risk genes, the significance for mutational burden is unestablished. Here, the authors sequence 125 candidate NDD genes in over 16,000 NDD cases; case-control mutational burden analysis identifies 48 genes with a significant burden of severe ultra-rare mutations.

Stephen Tapscott and colleagues report that human DUX4, which is linked to facioscapulohumeral dystrophy, and mouse DUX activate genes associated with cleavage-stage embryos, including retrotransposons, in muscle cells. They suggest that the ancestral DUX4-regulated genes characteristic of cleavage-stage embryos are driven by conventional promoters, whereas divergence of the DUX4 and DUX homeodomains correlates with retrotransposon specificity.

Genome sequencing and phylogenomic analysis show that the lungfish, not the coelacanth, is the closest living relative of tetrapods, that coelacanth protein-coding genes are more slowly evolving than those of tetrapods and lungfish, and that the genes and regulatory elements that underwent changes during the vertebrate transition to land reflect adaptation to a new environment.
