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).

A newly developed monoclonal antibody, MARV16, broadly neutralizes all Marburg virus isolates and provides effective protection in guinea pigs with Marburg virus disease.

Integrated photonic devices rely on single-mode waveguides, as inter-mode coupling prevents multimode waveguides from being efficiently bent for on-chip schemes. Using transformation optics, Gabrielliet al. overcome this limitation and show a multimode waveguide bend with minimal inter-mode coupling.

An analysis of the impact of logging intensity on biodiversity in tropical forests in Sabah, Malaysia, identifies a threshold of tree biomass removal below which logged forests still have conservation value.

Van Haute et al describe autosomal recessive TEFM variants that impair mitochondrial transcription elongation and reduce the levels of promoter distal mitochondrial RNA transcripts, leading to heterogeneous mitochondrial diseases with a treatable neuromuscular transmission defect.

Hypermutation and microsatellite burden determine responses and long-term survival following PD-1 blockade in children and young adults with refractory cancers resulting from germline DNA replication repair deficiency.

Here, Israeli and Finkel et al. perform genome-wide CRISPR knockout screens to identify host factors required for the infection with SARS-CoV-2 and two additionally variants of concern, Alpha and Beta, unveiling shared and differential host pathways required by the variants, and demonstrate GATA6 is critical for SARS-CoV-2 viral entry through modulation of ACE2 expression.

HLA peptidomic analysis identifies recurrent intracellular bacteria-derived peptides presented on HLA-I and HLA-II molecules in melanoma tumours, revealing how bacteria can modulate immune functions and responses to cancer therapies.

The evolutionary history of barley is analysed using ancient and modern DNA.

Using pancreatic organoids and genetic mouse models, Antonucci et al. show that cellular stress activates an NRF2–EZH2 epigenetic axis leading to metabolic reprogramming and subsequent malignant transformation of KRAS-mutant benign lesions.

There are only a few platforms that integrate multiple omics data types, bioinformatics tools, and interfaces for integrative analyses and visualization that do not require programming skills. Here the authors present an integrative web-based platform for analysis of omics data and signatures of cellular perturbations.

Tumor suppressor PALB2 is known to interact with BRCA1 and BRCA2, and to be required for the latter's localization to sites of DNA damage. Now PALB2 is shown to bind directly to DNA, to recombinase RAD51 and its accessory factor RAD51AP1. PALB2 also stimulates D loop formation by RAD51 in a synergistic manner with RAD51AP1.

Cibula et al. present survival results of the SENTIX trial and demonstrate that SLN biopsy alone does not increase the risk of disease recurrence in patients with early-stage cervical cancer.

Literature produced inconsistent findings regarding the links between extreme weather events and climate policy support across regions, populations and events. This global study offers a holistic assessment of these relationships and highlights the role of subjective attribution.

Plasmodium falciparum secretes extracellular vesicles (EVs) while growing inside red blood cells (RBCs). Here the authors show that these EVs contain assembled and functional 20S proteasome complexes that remodel the cytoskeleton of naïve human RBCs, priming the RBCs for parasite invasion.

Bacteria expressing an anti-tumor cytokine act as a potent cancer immunotherapy.

Acenes, or linearly fused benzene rings, have both fundamental scientific interest and potential for electronic and material utility, but synthesis of acenes with more than six rings are difficult due to dimerization and degradation. Here the authors prepare nonacene and demonstrate that it is stable in inert conditions.

Intratumoral tertiary lymphoid structure (TLS) density has been associated with better prognosis in several cancer types. Here the authors provide a comprehensive characterization of TLSs in patients with high-grade serous ovarian carcinoma.
