Endocytosis of TFR1 plays a crucial role in extracelluar iron uptake. Here the authors revealed that PKCβII facilitates the endocytosis of TFR1 and increases cellular iron levels through the phosphorylation of AAK1, thus promoting ferroptosis of tumor cells.

Toxic metal contamination in water represents one of the most urgent yet underrecognized threats to public health and the environment. Now, a functionalized nanopore capable of simultaneously detecting ten divalent metal ions in water offers a transformative tool for environmental monitoring and public health protection.

Transformations in organic chemistry are mainly limited to the incorporation of only one equivalent of the greenhouse gas CO₂ per substrate. Now, a visible-light photoredox-catalysed dicarboxylation of alkenes, allenes and arenes allows the incorporation of two CO₂ molecules into organic compounds.

Glycosylated asparagine residues that mediate the function of the B7H3 protein are unclear. Here the authors identify the important N-glycosylation sites for B7H3 cell surface localization and T cell inhibition, followed by the development of N91/309 and N104/322 preferentially targeting monoclonal antibody manifesting enhanced antitumor immunity.

Through CRISPR–Cas9 and kinase inhibitor screening, Zhang et al. show that PKCβII phosphorylates and activates ACSL4 to enhance polyunsaturated fatty acid-containing lipid biosynthesis, thereby promoting accumulation of lipid peroxidation and ferroptosis.

Cells undergoing ferroptosis secrete Galectin-13, which binds to CD44 and inhibits the plasma membrane localization of SLC7A11 in neighboring cells, thereby accelerating neighboring cell death and promoting ferroptosis propagation.

T cell mediated therapies have proven largely unsuccessful in triple-negative breast cancer (TNBC). Here, the authors show that autophagy is reduced in TNBC, which results in an increase in Tenascin C and reduced activation of tumour infiltrating lymphocytes.

Beclin 1 is an essential autophagy effector, necessary to form the autophagosome. Here Sun et al. show that Beclin 1 acetylation regulated by p300 and SIRT1 inhibits autophagosome maturation, and mutation of the acetylation sites leads to tumour growth suppression in vivo.

B7H3 is a transmembrane B7 family checkpoint molecule present on many cancer cells. Here the authors show that FUT8 mediates fucosylation of B7H3 to limit the immune response to triple-negative breast cancer as a potentially targeted mechanism of non-responsiveness to current checkpoint therapies.

Orbital hybridization in artificial atoms is achieved by altering their shape, and the anisotropy of the confining potential gives rise to the hybridization between quasibound states with different orbital quantum numbers within the artificial atom.

Graphene quantum dots have electronic structures resembling these of atoms. Here, the authors use two of these compounds to construct artificial molecules and study their electronic properties at tunable distances.

This study reveals that the synergistic effect of proton-limited environments and multi-site cooperative activation coupling substantially improves the electrocatalytic co-reduction of CO₂ and N₂ towards urea production, enabling gram-scale synthesis.

Gestational diabetes milletus (GDM) may have impairments on offspring health. Here, the authors suggest that the increase of EZH2 is an important reason for the disrupted DNA methylome in oocytes exposed to GDM, which may be associated with the transgenerational inheritance of the metabolic disorders.

Poorly differentiated hepatocellular carcinoma (HCC) is an aggressive disease with poor prognosis. Here the authors show that GDF1, a member of the TGF-β superfamily, is highly expressed in high-grade poorly differentiated HCC and is associated with tumor plasticity, and that GDF1-induced reexpression of cancer testis antigens could render tumors sensitive to immune checkpoint inhibition.

IL-2 is a classic T cell growth factor. Huang and colleagues demonstrate, however, that chronic IL-2 stimulation leads to a new exhaustion pathway that impairs antitumor immune responses.

Phase singularities are intimately related to orbital angular momentum. Direct local imaging of orbital angular momentum effects at the nanoscale remains challenging. Here, the authors demonstrate via scanning tunnelling microscopy that inter-orbital angular momentum scatterings induced by asymmetric potentials can modulate the phase singularities and induce single-wavefront dislocations.

The jujube is a major dry fruit crop in China and is commonly used for medicinal purposes. Here the authors sequence the genome and transcriptome of the most widely cultivated jujube cultivar, Dongzao, and highlight the genetic and molecular basis of agronomically important jujube traits, such as vitamin C content.

Small γ-Fe₂O₃ nanoparticles (<2 nm) encapsulated in the pores of a conductive metal–organic framework enable the efficient electrosynthesis of urea through the co-reduction of CO₂ and nitrate under neutral conditions.

Tumour repopulating cells (TRC) are stem-like cells that can escape immune-mediated killing. Here, the authors show IFN-γ results in either dormancy or apoptosis of TRC depending on the activation of the IDO1 metabolic pathway, and that combining IFN-γ with IDO1 inhibitors results in enhanced tumour regression.

Growing demand for food is confronting constraints to its sustainable production. This study finds that intercropping increases grain yields and their stability and that yield benefits increase over time.

Neuroblastoma cell differentiation is regulated by Id proteins. Here, the authors show that CaMKII-mediated phosphorylation of Beclin 1 can activate K63-linked ubiquitination and autophagic degradation of Id proteins uncovering a role for autophagy in cell differentiation.

Skp2 forms part of the SCF complex—an E3 ubiquitin ligase. Here the authors identify macroH2A1 as a novel target of Skp2 and propose an axis of regulation involving Skp2-macroH2A1-CDK8-p27 in cancer.

Population genomics uncover multiple independent origins and the importance of gene flow in the spread of target-site resistance mutations in the mite pest Tetranychus urticae.

Tumour-infiltrating lymphocytes (TILs) can be suppressed by the tumour, but how this occurs is not clear. Here the authors show that the miR-200 family, which suppresses epithelial–mesenchymal transition, also targets tumour cell PD-L1 and thereby intratumoral immunosuppression and metastasis.

Dai Zhang and colleagues report a genome-wide association study for schizophrenia in the Han Chinese population. They identify a new susceptibility locus at 11p11.2 and also identify a locus at 6p21-22.1 in the extended MHC region, which has previously been reported to be associated with schizophrenia in individuals of European descent.

Precise polarization measurements from the gamma-ray burst polarimeter POLAR suggest that the gamma-ray emission is at most polarized at a level lower than predicted by some models and also shows intrapulse evolution of its polarization angle.
