The zoonotic parasite Toxoplasma has complex developmental programs to accommodate different lifestyles that are important for parasite transmission and pathogenesis. Here, the authors discover a novel chromatin remodeling complex containing SNF2L in Toxoplasma and report its crucial roles in regulating the parasite’s developmental programs.

The common form of salt has a 1:1 ratio of Na⁺ and Cl⁻; however, species that deviate from this can be found under extreme conditions, such as high pressure. Now, as a result of cation–π interactions that promote ion–surface adsorption, Na₂Cl and Na₃Cl have been observed as two-dimensional crystals on graphene at ambient conditions.

Lei et al. develop a 4-1BB co-stimulated anti-CD19 CAR-NK cell product, show efficacy in pre-clinical models, and test safety and feasibility in a phase 1 trial in patients with refractory/relapsed large B cell lymphoma.

Therapeutic tolerogenic antigen-presenting cells can be generated in vivo by delivering, via lipid nanoparticles, mRNA coding for the inhibitory protein programmed death ligand 1, as shown in mouse models of rheumatoid arthritis and ulcerative colitis.

Oocyte meiotic defects increase with age and contribute to decreased oocyte quality. Here the authors show that granulosa cell mevalonate pathway abnormalities contribute to aneuploidy during ovarian aging and that supplementation with mevalonate metabolites improves oocyte quality, providing a potential therapeutic strategy for promoting female reproductive longevity.

Both cartilaginous and bony fishes have adaptive immune cells, but the evolutionary features of these diverse cell populations remain understudied. Here the authors report single-cell RNA sequencing atlas of both species to define these features and to find reduced evolutionary diversification of immune cells in cartilaginous fishes.

The quality of covalent organic frameworks is often compromised by structural damages induced during their activation procedure which influences their subsequent applications. Here, the authors describe a self-sacrificing guest strategy to synthesize high-quality two-dimensional COFs by incorporating salt guests within the pores of the COF structure.

Here, the authors report results from a randomized, placebo-controlled phase 3 trial of the tetravalent SARS-CoV-2 protein vaccine SCTV01E, demonstrating a favorable efficacy profile during a time when predominant viral variants were changing from BA.5 and BF.7 to XBB.

The microbial synthesis of carbon-containing compounds from single carbon precursors is desirable, yet designed pathways to achieve this goal overlap with host metabolism. Here the authors design a de novo metabolic pathway to assimilate formaldehyde into acetyl-CoA that does not overlap with known metabolic networks.

Volcano curves have become the gold standard in catalyst design. Here, the authors propose synergy-dependent volcano curves by disclosing both support- and adsorbate-induced catalyst restructuring, ideally bridging the gap between theoretical models and experimental observations.

The nucleus accumbens (NAc) is involved in mediating reward seeking and negative valence. Here, the authors present evidence for afferent-specific circuitry of the NAc in the control of reward and aversion via two distinct pathway.

Lymphocyte subsets remain inadequately understood in jawless vertebrates, relative to jawed vertebrates. In this study, the authors combine single-cell RNA and whole-transcriptome sequencing to demonstrate that the lamprey, Lampreta morii, harbours specialised T-like cells that are distinct from those found in jawed vertebrates.

Yao and Gong et al. identify WD40 repeat-containing protein 6 (WDR6) to be upregulated in the liver of insulin-resistant mice. WDR6 contributes to promoting hepatic de novo lipogenesis during insulin resistance by upregulation of fatty acid synthase, and the authors identify a small molecule to inhibit this effect of WDR6 and reduce hepatic steatosis.

Plant viruses adopt diverse strategies to inhibit host antiviral defense. Here the authors show that multiple different effectors from various rice viruses interfere with host gibberellin signaling by targeting the DELLA protein SLR1.

Antibodies against SARS-CoV-2 S protein can provide a treatment strategy for COVID-19. Here, Guo et al. provide the crystal structure of a SARS-CoV2 neutralizing antibody isolated from a convalescent patient and highlight the therapeutic efficacy in a rhesus monkey model of an engineered version with optimized pharmacokinetic and safety profile.

The cornea is susceptible to various injuries with a complicated repair process. Here, the authors propose a snowflake-inspired, blink-driven flexible piezoelectric contact lens for corneal injury repair.

The genome of the tropical blue-petal water lily Nymphaea colorata and the transcriptomes from 19 other Nymphaeales species provide insights into the early evolution of angiosperms.

Songlin Chen and colleagues sequenced the whole genomes of a male (ZZ) and a female (ZW) Chinese half-smooth tongue sole, Cynoglossus semilaevis. Their analysis provides insights into the structure and evolution of the sex chromosomes and adaptation to the benthic lifestyle of this flatfish.

The exclusion of cytotoxic T cells remains an important barrier to the efficacy of immunotherapies. Here the authors demonstrate that the combination anti-fibrosis agents and immune-enhanced cytokines can enhance T cell infiltration in a mouse model of pancreatic cancer.

Bacterial allosteric transcription factors can sense and respond to a variety of small molecules. Here the authors present CaT-SMelor which uses Cas12a and allosteric transcription factors to detect small molecules in the nanomolar range.

Biochemical and cellular assays show that the S. cerevisiae SAGA complex undergoes acetylation-dependent dimerization that enables the transcriptional coactivator to cooperatively acetylate nucleosomes, facilitate gene transcription and increase cell survival under stress conditions.

Failure of conventional clinical therapies such as tumor resection and chemotherapy are mainly due to the ineffective control of tumor metastasis. Here, the authors show that a systemic metastasis-targeted nanotherapeutic may offer a powerful adjunct therapy for suppressing tumor metastasis.

Senescent cells and their production of inflammatory cytokines (senescence-associated secretory phenotype) affects aging and disease, including cancer. Zhang et al. report that epigenomic remodeling by KDM4 controls the senescence-associated secretory phenotype, and KDM4 expression by stromal cells of the tumor microenvironment promotes prostate cancer.

Ta₃N₅ is a semiconductor with very promising photocatalytic properties. However, performing overall water splitting with this material has remained elusive. Now, Domen and co-workers report a method for the synthesis of defect-free single-crystal Ta₃N₅ nanorods capable of splitting water into hydrogen and oxygen in the presence of a co-catalyst.

The tumor microenvironment can influence patient survival response to therapy. Here, the authors used single-cell sequencing to investigate the microenvironment of nasopharyngeal cancer and identify tumor-specific signatures in five stromal clusters of cells that may influence patient survival.

Tumour microenvironment actively contributes to drug resistance in clinical oncology. Here, the authors show that genotoxic stress induces senescence in human stromal cells, which in turn secrete serine protease inhibitor Kazal type 1 (SPINK1) and promote acquired resistance of cancer cells via EGFR-mediated paracrine signaling.

The nearly complete genome of an early-diverging species, Stewartia sinensis, and phylogenomic studies provide insights into orphan gene evolution in Theaceae.

Huntington's disease is a neurodegenerative disease caused by the accumulation of mutant htt protein. Now, two groups led by Dimitri Krainc and Wenzhen Duan report that mutant htt binds and inactivates the deacetylase enzyme SIRT1 and that SIRT1 overexpression is protective in Huntington's disease mouse models.
