Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

The absence of a band gap in graphene hinders its use in electronics. Here, the authors open a band gap as large as 3.9 electronvolts in graphene grown by chemical vapour deposition by treating it in hydrogen plasma, and then use this material to create a room temperature field- effect transistor.

The prognosis and treatment of gastric cancer is complicated by heterogeneity. Here, the authors reveal two molecular subtypes, the mesenchymal subtype associated with poor survival and chemoresistance, and the epithelial phenotype associated with better survival and sensitivity to chemotherapy.

Swapan Nath, Sang-Cheol Bae and colleagues report the results of a large-scale association study of systemic lupus erythematosus in individuals of Asian ancestry. They identify several new susceptibility loci and find enrichment for signals near genes implicated in B cell and T cell function.

Grain boundaries in polycrystalline materials may offer the opportunity to explore physical phenomena that do not normally occur within the crystal grains. Here, the authors show that twin boundaries in Bi₂Te₃works as an electron supply for the whole bulk material.

The extracellular matrix is remodeled to form complex interconnected network structures that regulate stem cell behaviors. Here, the authors modulate extracellular matrix-like networks using magnetic nano-blockers, adjusting stem cell behavior by changing ligand inter-cluster connectivity. This dynamic system provides new insights into cell-material interactions for tissue regeneration.

Identifying the mechanisms underlying the early inflammatory phase of aortic valve disease is crucial for disease prevention. Here the authors perform single-cell RNA sequencing to show the immunomodulatory role of PPARγ in valvular endothelial cells during hyperlipidemia.

The Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL) in South Korea has now entered operation with a timing jitter of just 20 fs.

The genetic link between placenta function and congenital heart defects has been established, though the cellular mechanisms underlying this connection is less clear. Here they show that PIBF1 regulates syncytiotrophoblast fusion and that loss of PIBF1 also negatively impacts heart development, providing a potential link between the development of these two organs.

A stealthy neural recorder allows for the study of the behaviour of non-human primates in naturalistic settings.

Calcium flux must be carefully controlled during the phagocytosis of apoptotic cells (efferocytosis), although how this occurs is not fully understood. Here, the authors show that the Cereblon E3 ligase regulates Orai1 degradation and subsequently SOCE-mediated calcium influx.

Electrolyte engineering has proven an effective approach to enhance the performance of lithium metal batteries. Here the authors propose a strategy by using multiple solvents in weakly solvating electrolytes—dubbed as high-entropy electrolytes—to improve the ionic conductivity while maintaining electrochemical stability, leading to high-performance batteries.

Analysis of genomic and transcriptomic data from 462 patient-derived tumor cell (PDC) samples across 14 cancer types, along with pharmacological responses to 60 agents, indicates that PDC-derived drug sensitivities might be predictive of clinical response to targeted therapies.

Quantum mechanical resonant tunnelling is believed to be only feasible in semiconductor-based heterostructures due to high crystalline quality required, which restricts the number of viable materials. Here, the authors demonstrate resonant tunnelling in a deliberately designed complex-oxide superlattice.

The first conference on ‘Infection and Immunity’ was organized by the Institute for Basic Science and Korean Association of Immunologists and held in Daejeon, South Korea, from 12 to 14 July 2023. The conference focused on the biology of CD8⁺ T cells in the context of viral disease and cancer.

High-throughput sequencing is used to identify somatic variants in cancer patients. Here, the authors perform panel-based profiling of 5095 clinical samples and demonstrate that many clinically-actionable variants have low variant allele fractions, requiring assays with high detection sensitivity.

Virtual memory T cells have antimicrobial functions but whether they can contribute to inflammatory pathology is unclear. Here the authors show that a subset of CD8⁺ T cells that originates from virtual memory T cells upon cytokine stimulation can drive the chronic inflammatory disease alopecia areata via innate-like cytotoxic effector functions.

PEER-seq characterizes the drug resistance profiles of thousands of genetic variants.

Subtyping of non-small cell lung cancer can be challenging based on pathology. Here, the authors utilise multi-omics analysis of 229 patients to identify further subtypes, and altered immune composition between subtypes.

Even in patients who are initially sensitive, patients treated with platinum-based therapies often go on to relapse and have limited treatment options. Here, the authors report the efficacy and safety of a phase II trial investigating olaparib, pembrolizumab and bevacizumab as maintenance therapy in platinum-sensitive recurrent ovarian cancer.

There is growing interest in designing electrolytes to enable Li-metal batteries. Here the authors show that asymmetric solvents improve lithium redox kinetics and achieve long cycle life in anode-free cells under electric vertical take-off and landing conditions, demonstrating potential for future high-power applications.

Electrides are an emerging family of materials with potential for hosting topological states. Here, the authors demonstrate the presence of Fermi-arc surface states in close proximity to the floating electron layer on the surface of an electride.

Nguyen et al. show that the E3 ubiquitin ligase MARCHF6 acts as an NADPH sensor to suppress ferroptosis. Mechanistically, NADPH binds to MARCHF6 and activates its E3 ligase activity, enhancing the degradation of pro-ferroptosis proteins.

Sung et. al. identify genetic, molecular and clinical risk factors for immune-related adverse events in multicancer cohorts of patients treated with checkpoint inhibitors and develop predictive models that they validate in an independent cohort.

In this study, the authors introduce the concept of a unique cellular subtype within the organic stroma, which does not conform to a typical young or senescent but is significantly associated with age-related organic dysfunction among the elderly.

In patients with advanced gastric cancer (AGC), resistance to treatment with trastuzumab and cytotoxic chemotherapy remains high. Here, the authors report the results of a phase Ib/II clinical trial assessing the safety and clinical response to a quadruplet regimen of pembrolizumab, trastuzumab, capecitabine, and cisplatin as a first-line therapy for HER2-positive AGC.
