Isolating purified electrosynthesis product is a major challenge in electrochemical carbon dioxide reduction. Here, the authors report a nanotwinned silver electrocatalyst and a pneumatic-trough cell system to produce a 52% concentrated CO, which is further utilized as a carbon feedstock for graphene production.

The generation of α-carbon radicals from alkoxyl radicals is challenging because 1,2-hydrogen atom transfer (HAT) is usually less favoured than 1,5-HAT. Here, the authors report a strategy to inhibit 1,5-HAT by introducing a silyl group into the α-position of alkoxyl radicals, enabling preparation of α-alkoxylimino alcohols and α-heteroaryl alcohols.

Nitroformate is an attractive oxidant compound in propellants and explosives but its poor thermostability prevents it from application. Here, the authors demonstrate that incorporation of nitroformate in a hydrogen-bonded organic framework increases the thermostability of nitroformate.

The implementation of spiking neural network in future neuromorphic hardware requires hardware encoder analogous to the sensory neurons. The authors show a biomimetic dual-gated MoS₂ field effect transistor capable of encoding analog signals into stochastic spike trains at energy cost of 1–5 pJ/spike.

Li-ion battery electrodes contain inactive materials, such as conducting agents and polymeric binders, which limit the energy density. Here, the authors demonstrate highly dense Ni-rich cathodes with improved volumetric capacities by coating graphene and minimizing the inactive components.

There is some disagreement between climate models about how much precipitation changes under global warming. Here, the authors use the ocean surface energy balance to constrain the sensitivity of precipitation to historical warming and find that it is increasing by 0.68 ± 0.51% per degree warming.

This study introduces an empirical modeling approach allowing to separate climate and socio-economic drivers of damages by fluvial floods. It shows that climate signals are clearly detectable in Asia and Latin America.

The Permian–Triassic mass extinction was accompanied by a massive release of carbon into the ocean-atmosphere system, but the magnitude of change is not well known. Here, the authors present a new record of C₃ plants from southwestern China which shows that atmospheric pCO₂ increased by a factor of six during this event.

Here, the authors investigate the aboveground carbon sink efficiency of Andean forests. The study shows the high potential of these forests to serve as future carbon refuges, and urges to reduce deforestation and increase restoration.

Microbial oxidoreductases are key in biomass breakdown. Here, the authors expand the specificity and redox scope within fungal auxiliary activity 7 family (AA7) enzymes and show that AA7 oligosaccharide dehydrogenases can directly fuel cellulose degradation by lytic polysaccharide monooxygenases.

Here, the authors combine 16 S rRNA sequencing, culture and bioinformatics to profile the microbiome in 234 serial bronchoalveolar lavage samples from 64 lung transplant recipients collected over 49-months and identify distinct compositional states, termed pneumotypes, linked to current health status, and establish a collection of primary lung bacterial isolates, LuMiCol.

Mito-SEPs are small peptides that can modulate oxidative metabolism in mitochondria. Here the authors show that C15ORF48 encodes a mito-SEP, MOCCI, capable of altering mitochondria respiration to suppress inflammation, while C15ORF48 3’ untranslated region also contains a miRNA, miR-147b, that synergizes with MOCCI to modulate host anti-viral responses.

The molecular identity of renal glomerular cells is poorly characterized and rodent glomerulopathy models translate poorly to humans. Here, the authors show molecular signatures of glomerulus-associated cells using single cell RNA sequencing and highlight differences between mouse and human cells.

The mechanism by which parathyroid hormone mediates the switch from bone resorption to bone formation is unclear. Here, the authors show that SLPI regulates the communication between osteoblasts and osteoclasts to promote the anabolic effect of parathyroid hormone.

Population-based studies of SARS-CoV-2 seroprevalence are needed to understand levels of immunity and antibody dynamics. Here, the authors show that the seroprevalence in Bonn, Germany was low (<1%) following the first epidemic wave, and that neutralising antibodies waned within a few months.

Our understanding of the immune response to SARS-CoV-2 infection is still incomplete. Here, the authors find that IL-33, produced during immune recall potentially by CD14⁺ monocytes, correlates with CD4⁺ T cell activation, anti-SARS-CoV-2 antibody titer, and disease severity in a cohort of convalescent individuals professionally exposed to the virus.

High myopia is associated with lens changes, but the underlying mechanisms are unclear. Here, the authors show increased equatorial diameter of the lens in subjects affected by high myopia, and find that these changes are associated with an increase in crystallin expression driven by the transcription factor MAF and TGF-β1 signaling.

Adverse climatic conditions are commonly reported to shape asylum migration, but their effect relative to other drivers is unknown. Here the authors compare climatic, economic, and political factors as predictors of future asylum flows to the EU and find that war and repression are the most important factors.

The effectiveness of large historical efforts for decarbonizing steel production is unclear. Here, the authors show that such efficiency gains were offset by a booming steel demand increase. This has led to a stagnating decarbonization progress over past decades, which jeopardizes realization of future climate targets.

The value assessment of job skills is critical for companies to select and retain the right talent and for individuals to develop them. Here the authors show that a data-driven method based on an enhanced neural network can assign meaningful value to job skills in a quantitative way and outperforms benchmark models for job salary prediction.

Recent technological, social, and educational changes are profoundly impacting our work, but what makes labour markets resilient to those labour shocks? Here, the authors show that labour markets resemble ecological systems whose resilience depends critically on the network of skill similarities between different jobs.
