Human transplantation with allogeneic donor organs results in non-matching of MHC and differential presentation of T cell antigens. Here the authors show that in a lung transplanted SARS-CoV-2 infected patient T cell responses generated from the host may not be able to recognise infected cells within the graft and this may contribute to virus persistence.

Variants in NOS1AP can cause monogenic nephrotic syndrome. Here, the authors show that disrupting the intergenic NOS1AP splice isoform that is more prevalent in podocytes leads to monogenic kidney disease responsive to RAAS inhibition.

There are many open questions around the mechanism of sex chromosome dosage compensation in birds. In this study, Papanicolaou et al. show that female avian cells upregulate their single Z chromosome via increased transcriptional burst frequency and enhanced translation, revealing parallels with mammalian dosage compensation.

In mammals, the enzyme TGDS produces UDP-4-keto-6-deoxyglucose, which binds to the catalytic pocket of UDP-xylose synthase, thereby regenerating the essential NAD⁺ cofactor of UDP-xylose synthase in conditions of low NAD⁺.

A survey shows that variation in responses to ocean acidification among ecotypes of a widely distributed picoplankton species is similar to that found between different genera. The findings should also help to predict evolutionary change within species and how the composition of phytoplankton communities will change in a high-CO₂ world.

Classical photochemistry requires nanosecond excited-state lifetimes for diffusion-controlled reactions. Here the authors provide direct evidence for the elusive pre-association between radical ions and substrate molecules, enabling photoinduced electron transfer beyond the diffusion limit.

The authors study kagome superconductor LaRu3Si2 under pressure up to 40 GPa. They find a superconducting dome as a function of pressure, with Tc reaching its maximum when the coexisting charge order remains long-range.

The Yu-Shiba-Rusinov state, arising from exchange coupling between a magnetic impurity and a superconductor, undergoes a quantum phase transition at a critical coupling. In a scanning tunnelling microscopy experiment, Karan et al. reveal distinct tunnelling spectra on each side of the transition in a magnetic field, which allows them to distinguish the free spin regime from the screened spin regime.

JWST data show that the exoplanet WASP-18b has thermally distinct regions of its dayside. The authors mapped the sizes of these regions, measured their temperatures and potentially identify water destruction in the hottest region.

Magnetic impurities on superconductors lead to bound states within the superconducting gap, so called Yu-Shiba-Rusinov (YSR) states. Here, the authors study tunneling from a vanadium STM tip to a V(100) surface and show that YSR states can be excited at very low temperature by applying a microwave signal.

The neural basis of how the visual cortex processes complex features remains under active investigation. Here, the authors show that broadband stimuli increase neural responses and visual perception due to a reduction in center-surround suppression.

Our understanding of how post-translational modification—protein phosphorylation—impacts the complexity of eukaryotic signalling pathways is continuously expanding. Now, protein oligophosphorylation has been characterized as an additional phosphorylation mode. Structural and mass spectrometry methods revealed that NME1 catalysed its own oligophosphorylation, leading to altered protein–protein interactions.

In this work, Björn Lamprecht et al. found that survival of Hodgkin's lymphoma cells requires activity of the growth factor receptor CSF1R. Transcription of the gene encoding CSF1R was unexpectedly discovered to originate in a specific class of long terminal repeat, a type of repetitive element present in the genome. Transcriptional initiation from this class of long terminal repeats was widely activated in Hodgkin's lymphoma cells, which the authors traced to defects in epigenetic silencing (517–518).

Turbulence onset in shear flows is often modeled as a memoryless directed percolation (DP) transition. The authors show that in channel flow, turbulent stripes age near the critical point, questioning the DP analogy and revealing geometry-dependent transition dynamics.
