Reduced dependence on wild-caught fish in favour of crop-based ingredients for feeds has supported aquaculture growth. An analysis of ingredient origins versus feed composition shows that origin must be considered to assess the environmental footprint of feed production.

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 global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

Hetero-oligomeric proteins offer many advantages for bioengineering efforts but are difficult to make from scratch. Here, authors present a simple method for creating pseudosymmetric hetero-oligomers from input symmetrical proteins.

When our actions conflict with our prior attitudes, we often change our attitudes to be more consistent with our actions, a phenomenon that is known as cognitive dissonance. Here the authors report that activity during cognitive dissonance in the dorsal anterior cingulate cortex and anterior insula predicts subsequent attitude changes.

Dimethyl fumarate (DMF) is an anti-inflammatory drug proposed as a treatment for COVID19. Here the results are reported from a randomised trial testing DMF treatment in 713 patients hospitalised with COVID-19. DMF was not associated with any improvement in day 5 outcomes.

Entanglement was observed in top–antitop quark events by the ATLAS experiment produced at the Large Hadron Collider at CERN using a proton–proton collision dataset with a centre-of-mass energy of √s  = 13 TeV and an integrated luminosity of 140 fb⁻¹.

A conserved network of bacteria and fungi underpins cadaver decomposition despite selection effects of location, climate and season.

CRISPR-based nucleic acid detection is used in a platform that can simultaneously detect 169 human-associated viruses in multiple samples, providing scalable, multiplexed pathogen detection aimed at routine surveillance for public health.

CD8⁺ T cell–macrophage interactions have a central role in impairing alveolar regeneration and driving fibrotic sequelae after acute viral pneumonia in a mouse model of long COVID.

Roy et al. describe a generalized method for computationally designing miniproteins selective for a single integrin heterodimer and conformational state. The designed αvβ6 inhibitor remains monomeric and maintains biological activity following aerosolization and shows excellent efficacy in bleomycin induced lung fibrosis.

A genome-wide association study of critically ill patients with COVID-19 identifies genetic signals that relate to important host antiviral defence mechanisms and mediators of inflammatory organ damage that may be targeted by repurposing drug treatments.

The trRosetta neural network was used to iteratively optimise model proteins from random 100-amino-acid sequences, resulting in ‘hallucinated’ proteins, which when expressed in bacteria closely resembled the model structures.

Outbreaks of viral hemorrhagic fevers highlight the need for sensitive, field-deployable diagnostics. Here the authors present a CRISPR-based SHERLOCK platform with field protocol and mobile app for Ebola and Lassa fever outbreaks.

Fluorescent protein reporters based on GFP exist, but have intrinsic disadvantages. Here the authors incorporate pH, Ca²⁺ and protein–protein interaction sensing modalities into de novo designed mini-fluorescence-activating proteins (mFAPs), with increased photostability and smaller size, which bind a range of DFHBI chromophore variants.

The ATLAS Collaboration reports a measurement of the ratio of the decay rates of W bosons to τ leptons and muons, in agreement with universal lepton couplings as postulated in the standard model of particle physics.

The ATLAS experiment at the Large Hadron Collider reports a search for charged-lepton-flavour violation in decays of Z bosons into a τ lepton and an electron or muon of opposite charge.

A modular de novo designed biosensor platform consisting of a cage and key molecule is developed, and used to create sensors for seven distinct proteins including the spike protein from SARS-CoV-2 and anti-SARS antibodies.

SITE-Seq probes Cas9 cleavage sites in vitro and returns a comprehensive list of off-target sites at different Cas9–sgRNA concentrations.

The measurement of the total cross-section of proton–proton collisions is of fundamental importance for particle physics. Here, the first measurement of the inelastic cross-section is presented for proton–proton collisions at an energy of 7 teraelectronvolts using the ATLAS detector at the Large Hadron Collider.

The BTK inhibitor ibrutinib is used to treat chronic lymphocytic leukaemia, however some patients develop resistance to the drug. Here, the authors use genomic analyses to examine the clonal evolution of 5 patients that develop resistance to ibrutinib.

Openshaw and colleagues find myeloid inflammation and complement activation signatures in patients with long COVID who were previously hospitalized.

Mammalian genomes are scattered with repetitive sequences, but their biology remains largely elusive. Here, the authors show that transcription can initiate from short tandem repetitive sequences, and that genetic variants linked to human diseases are preferentially found at repeats with high transcription initiation level.

The ATLAS Collaboration reports the observation of the electroweak production of two jets and a Z-boson pair. This process is related to vector-boson scattering and allows the nature of electroweak symmetry breaking to be probed.

Ten years after the discovery of the Higgs boson, the ATLAS  experiment at CERN probes its kinematic properties with a significantly larger dataset from 2015–2018 and provides further insights on its interaction with other known particles.

A sophisticated study of error-related brain potentials in patients with prefrontal lesions addresses how we monitor performance and adjust cognitive control based on task demands.

Adam Bass, Gad Getz and colleagues report whole-exome sequencing of 149 esophageal adenocarcinomas (EACs) and whole-genome sequencing of 15 EACs. They identify a mutational signature defined by a high prevalence of A>C transversions, as well as 26 genes mutated at high frequency in EACs.

De novo protein nanostructures are typically assembled via top-down approaches. Here, the authors developed a bottom-up approach, using split inteins to ligate multiple copies of a three-helix bundle to create 2D triangular and square-shaped structures with high stability.
