Optoelectronic and photonic devices require materials with multiple, often conflicting functionalities, leading to integration challenges. Here, the authors demonstrate that layered PdSe₂ is suitable for infrared photodetection, light guiding and photothermal applications due to its peculiar semimetallic band structure.

Multiomic factor analysis of blood multiomic data, including single-cell transcriptomics, for individuals with either acute or chronic coronary syndrome identifies immune cell signatures that correlate with treatment outcomes.

The involvement of cAMP-dependent regulation of HCN4 in the chronotropic heart rate response is a matter of debate. Here the authors use a knockin mouse model expressing cAMP-insensitive HCN4 channels to discover an inhibitory nonfiring cell pool in the sinoatrial node and a tonic and mutual interaction between firing and nonfiring pacemaker cells that is controlled by cAMP-dependent regulation of HCN4, with implications in chronotropic heart rate responses.

Infection with SARS-COV-2 can result in self-limited upper airway infection or progress to a more systemic inflammatory condition including pneumonic COVID-19. Here the authors utilise a multi-omics approach to interrogate the immune response of patients with self-limiting upper respiratory SARS-CoV-2 infection and reveal a temporal immune trajectory they associate with viral containment and restriction from pneumonic progressive disease.

The cGAS-STING pathway senses cytosolic DNA to activate interferon responses, but has also been implicated in autophagy induction. Here the authors show that, during herpes simplex virus infection, cGAS-induced autophagy is mediated by TBK1-induced TRIM23 phosphorylation and downstream signaling events to assist in antiviral immunity.

Maternal immune activation during pregnancy can negatively impact the developing fetus. Here, applying multi-omics (RNA-seq, phosphoproteomics and lipidomics) and imaging, the authors show that while maternal immune activation induces strong innate response in maternal organs it does not extend through the placenta but leads to fetal metabolic changes.

Carbon- and silicon-based triplet diradicals with two unpaired electrons are proposed as intermediates in organic and organometallic reactions but their isolation is challenging. Now, isolable 1,3-disilapyrroles are reported to act as organosilicon-based delocalized triplet diradicals and mediate the cleavage of the CO triple bond and C(sp³)–H bond activation.

Plasmacytoid dendritic cells monitor the bone marrow for apoptotic megakaryocytes (MKs) and deliver IFNα to the MK niche, triggering local on-demand proliferation and maturation of MK progenitors.

In this Clinical Outlook, we describe available multiomic studies in cardiovascular medicine, discuss the advantages and potential of multiomic techniques for clinical translation in cardiology, and highlight three promising aspects: the generation of unprecedented cellular atlases, the identification of composite diagnostic and prognostic biomarkers derived from integrative multiomic signatures, and the isolation of potential therapeutic targets from unbiased comprehensive datasets and analyses.

Thermal annealing of SiC produces graphene layers on an insulating substrate, but the material is highly inhomogeneous. It is now shown that an argon atmosphere during annealing improves uniformity of the graphene layers dramatically and yields better transport characteristics. This is a very important result for the development of graphene-based electronic devices.

The authors describe the cocrystal structure of the highly efficient polyethylene terephthalate-degrading hydrolase PHL7 with its product terephthalic acid and elucidate the role of residues in subsites I and II for its thermal stability and of residue L210 for its high activity.

Assembling multicomponent catalysts to harness synergic effects is challenging. Now, flame spray pyrolysis permits the synthesis of ternary Pd-In₂O₃-ZrO₂ catalysts with an optimal architecture and an enriched density of oxygen vacancies for maximal performance in CO₂-based methanol synthesis.

Analysis of Pax7 dynamics during pituitary lineage specification shows that Pax7 binds rapidly at uniquely marked heterochromatin pioneer sites and initiates chromatin opening that remains stable after Pax7 withdrawal, with loss of DNA hypermethylation at pioneered enhancers.

Breakdown of vascular barriers is a major complication of inflammatory diseases. However, the mechanisms underlying platelet recruitment to inflammatory micro-environments remains unclear. Here, the authors identify haptotaxis as a key effector function of immune-responsive platelets

Vpu prevents HIV superinfection and immune activation by modulating DNA repair mechanisms, particularly by inhibiting homologous repair. Vpu achieves this by disrupting the RanBP2–RanGAP1*SUMO1–Ubc9 complex at the nuclear pore to reduce PML SUMOylation and consequent PML nuclear body formation, which hampers the homologous recombination factors Rad52 and BLM.

Cathelicidins are antimicrobial peptides that eliminate pathogens and contribute to the innate immune response. Here the authors show that neutrophil-derived LL-37/CRAMP induces platelet activation and promotes arterial thrombosis and thrombo-inflammation.

Premature infants can suffer from an anatomical defect in which the ductus arteriosus, a blood vessel that connects the pulmonary artery and the aorta during fetal development, fails to close at birth. Katrin Echtler et al. now show that platelets are needed for closure in mice and that reduced platelet function may be clinically relevant: in a retrospective study of preterm human infants, low platelet counts were associated with the presence of an unclosed ductus arteriosus.

The signals involved in coordinating the navigation of myeloid cells in tissues are incompletely understood. Massberg and colleagues show that NG2⁺ pericytes control the pattern and efficacy of interstitial leukocyte migration.

In this Review, Stark and Massberg discuss how the interplay between innate immunity, platelet activation and coagulation, known as immunothrombosis, functions as a host defence mechanism to limit pathogen spreading, yet its aberrant activation, termed thromboinflammation, results in thrombotic complications, highlighting the therapeutic potential of anti-inflammatory strategies in cardiovascular pathologies.

Numerical models of dynamic topography, glacial isostatic adjustment and reef isostasy help reconcile the discrepancy between onshore and offshore sea-level indicators of the Last Interglacial in Queensland, Australia

Cardiac imaging has a pivotal role in the prevention, diagnosis and treatment of ischaemic heart disease. In this Consensus Statement, the authors summarize the use of SPECT, PET, MRI, echocardiography, CT and invasive coronary flow and pressure measurement, and describe the relative strengths and weaknesses of each modality.

A large-scale GWAS provides insight on diabetes-dependent genetic effects on the glomerular filtration rate, a common metric to monitor kidney health in disease.
