Type I interferons (IFNs) have strong antitumour activity yet their clinical use is limited by their off-target toxicity and by their effect on immune evasion. Here the authors design a biomimetic nanoparticle loaded with an IFN inducer, which can at the same time replenish intratumoural IFNs and reduce their immunosuppressive activity, showing therapeutic efficacy in several animal tumour models.

In a large prospective cohort of 1,090 pregnant women with a high risk of fetal genetic diseases, a cell-free DNA screening identified cases of aneuploidies, microdeletions and monogenic variants with high accuracy in concordance to standard diagnostic tests

High fidelity manipulation of diamond-based spin qubits is difficult at room temperature because of decoherence. Here, the authors show a universal set of logic gates in nitrogen-vacancy centres with average single-qubit and two-qubit gate fidelities of 0.999952 and 0.992, respectively.

CLE19 is a secreted peptide required for pollen development and other processes in Arabidopsis. Here the authors show that PXL1 and SERKs act as receptors and co-receptors for CLE19 and regulate tapetum transcriptional networks that promote pollen development.

ASPP1 promotes apoptosis of cardiomyocytes by increasing the trafficking of p53 to the nucleus. Here the authors show that, in fibroblasts, ASPP1 promotes the ubiquitination and degradation of p53, decreasing myofibroblast activity and improving cardiac fibrosis and function after myocardial infarction.

The genetic factors involved in liver injury remain largely unknown. Here, the authors show that ASGR1 deficiency induces liver injury by activating the GP73-mediated ER stress pathway, suggesting its role as a genetic determinant influencing susceptibility to liver injury.

Coupling a single-photon emitter to a mechanical resonator enables the generation of single phonons. Here, the authors study the interaction of a single-photon emitter and a phononic-crystal resonator in the sideband-resolved regime.

Analyses of the genome sequences and expression data for two closely related mycoheterotrophic orchid species provide insights into the genomic basis underlying the evolution of mycoheterotrophy.

In Klinefelter syndrome, gene dysregulation due to the extra X chromosome leads to delayed development of fetal germ cells (FGCs), and aberrant interactions between Sertoli cells and FGCs disrupt the migration of late FGCs to the basement membrane.

Malfunctioning of cellular organelles, such as the endoplasmic reticulum (ER) and mitochondria, can have a role in stress-induced pathophysiological changes. Here, the authors show that increased mitochondria‐associated endoplasmic reticulum membranes contacts related to ATP-P2X7 receptor signaling contribute to stress responses in microglia and the development of depression-like behavior in male mice.

Yuan et al. demonstrate that cancer-associated fibroblasts in the pancreatic tumor microenvironment secrete nucleosides through autophagy in an NUFIP1-dependent manner, thereby inducing glucose consumption under glutamine-deprived conditions and promoting tumor growth.

CAR T therapy has some efficacy in the treatment of patients with refractory/relapsed B-cell acute lymphoblastic leukemia; however in some patients further relapse is encountered. Here, the authors conduct a Phase II clinical trial of a CD19 CAR T and demonstrate that patients with extramedullary disease are more likely to relapse than those without.

Analysis of the fungal and bacterial components of the intestinal microbiota of patients undergoing allogeneic haematopoietic cell transplantation identifies an association between fungal dysbiosis, an expansion of Candida parapsilosis complex species and worse patient outcomes.

Shi et al. profiled small non-coding RNAs (sncRNAs) through PANDORA-seq, which identified tissue-specific transfer RNA- and ribosomal RNA-derived small RNAs, as well as sncRNAs, with dynamic changes during induced pluripotent stem cell reprogramming.

In Arabidopsis, microRNAs control the transition from juvenile to adult states. The study, using genomic, genetic and molecular approaches, investigates how miR156 and miR157 are re-activated at each generation.

In nonlinear tracking control, relevant to robotic applications, the knowledge on the system model may be not available and there is current need in model-free approaches to track a desired trajectory, regular or chaotic. The authors introduce here a framework that employs machine learning to control a two-arm robotic manipulator using only partially observed states.

We introduce a major scientific endeavour called π-HuB (proteomic navigator of the human body), its aim being to generate and harness multimodality proteomic datasets to enhance our understanding of human biology.

Zhong et al. show that increased lipid intestinal absorption can contribute to fat mass increase after dieting and this is mediated by Lactobacillus-secreted metabolites. Notably, Lactobacillus growth can be counteracted by refeeding a high-protein diet, thus preventing weight regain.
