The CMS Collaboration reports the measurement of the spin, parity, and charge conjugation properties of all-charm tetraquarks, exotic fleeting particles formed in proton–proton collisions at the Large Hadron Collider.

Boiling, despite being a well-known phenomenon still lacks an understanding of its multiscale and non-equilibrium nature. Using the stochastic mesoscale model based on fluctuating hydrodynamics and diffuse interface approach Gallo et al. describe the process of boiling from nucleation to macroscopic bubble dynamics.

The quark structure of the f₀(980) hadron is still unknown after 50 years of its discovery. Here, the CMS Collaboration reports a measurement of the elliptic flow of the f₀(980) state in proton-lead collisions at a nucleon-nucleon centre-of-mass energy of 8.16 TeV, providing strong evidence that the state is an ordinary meson.

Fifteen years’ follow-up of clinical development and real-world data from 43 patients show that gammaretroviral gene therapy for adenosine deaminase deficiency has a positive long-term efficacy profile, warranting continued safety monitoring of patients receiving gene therapy.

Self-renewing cells play an important role in initiation, progression, and therapy resistance in glioblastoma. Here, the authors identify histone variant macroH2A2 as a regulator of chromatin organisation resulting in the suppression of transcriptional programs of self-renewal in glioblastoma.

Abeysundara, Rasnitsyn, Fong et al. report that the presence of leptomeningeal metastatic tumour cells leads to the recruitment and remodelling of fibroblasts, which, in turn, facilitate the colonization and outgrowth of medulloblastoma cells in the leptomeninges.

Analysis of medulloblastomas in humans and mice shows that the functional consequences of ZIC1 mutations are exquisitely dependent on the cells of origin that give rise to different subgroups of medulloblastoma.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

The most up-to-date combination of results on the properties of the Higgs boson is reported, which indicate that its properties are consistent with the standard model predictions, within the precision achieved to date.

The CMS Collaboration reports evidence for off-shell Higgs boson contributions in the production of Z boson pairs, and measures the width of the Higgs boson, which is inversely related to its lifetime.

The CMS Collaboration reports the study of three simultaneous hard interactions between quarks and gluons in proton–proton collisions. This manifests through the concurrent production of three J/ψ mesons, which consist of a charm-quark–antiquark pair.

First-in-human test of topical application of a commensal bacterium on skin of individuals with atopic dermatitis reduces colonization by proinflammatory Staphylococcus aureus.

AMBRA1-mediated degradation of cyclin D through CRL4–DDB1 regulates cell proliferation and prevents replication stress in neurodevelopment and cancer.

Reliably identifying transient intermediates is crucial to elucidate chemical reaction mechanisms. Here, the authors use femtosecond Fe Kβ main line and valence-to-core x-ray emission spectroscopy to characterize a short-lived intermediate of the aqueous ferricyanide photo-aquation reaction.

Chen et al. show that subtypes of immune cells in prenatal human brain promote angiogenesis in the germinal matrix. Conversely, in preterm infants, proinflammatory immune cells disrupt angiogenesis and promote germinal matrix hemorrhage.

Using unique barcodes for tumour cells, the authors explore the dynamics of human glioblastoma subpopulations, and suggest that clonal heterogeneity emerges through stochastic fate decisions of a neutral proliferative hierarchy.

Efficient repair of demyelinated CNS lesions involves the resolution of inflammation and induction of remyelination. Berghoff et al. show that sterol synthesis in microglia is key to both processes, which can be supported by squalene therapy.

Combined analysis of proton-proton collision data from the Large Hadron Collider at CERN by the CMS and LHCb collaborations leads to the observation of the extremely rare decay of the strange B meson into muons; the result is compatible with the standard model of particle physics, and does not show any signs of new physics, such as supersymmetry.

Pleural mesothelioma (PM) exhibits altered lipid metabolism and NFκB dysregulation, driven by FABP5, promoting tumor growth and inflammation. Silencing FABP5 alters cell dynamics, suggesting it as a potential therapeutic target in PM.

Nada Jabado, Jacek Majewski, Annie Huang and colleagues show that embryonal tumors with multilayered rosettes are characterized by a recurrent fusion of TTYH1 with the C19MC microRNA cluster. They further show that this fusion results in massive overexpression of a brain-specific isoform of DNMT3B, suggesting that this pediatric brain tumor is driven by epigenetic reactivation of an early developmental neurogenesis program.

Relativistic modelling of long X-ray observations of a highly variable active galaxy reveals that the height of its X-ray corona increases with increasing luminosity. X-ray reverberation is shown to be a powerful technique to measure black hole masses.

X-ray detection of an ultrafast outflow of gas is strongly linked with energy emission from the inner accretion disk of a black hole, suggesting that X-rays ionize the outflowing disk wind.

Memristors hold promise for massively-parallel computing at low power. Aguirre et al. provide a comprehensive protocol of the materials and methods for designing memristive artificial neural networks with the detailed working principles of each building block and the tools for performance evaluation.

Power exhaust is one of the biggest challenges stopping fusion energy. This article shows experimental evidence for strategically shaping the power exhaust region as a solution to this challenge, utilising physics understanding to strike a balance between engineering complexity and power exhaust benefits, consistent with reduced models and simulations.
