Interaction between Cooper pairs and other collective excitations may reveal important information about the pairing mechanism. Here, the authors observe a universal jump in the phase of the driven Higgs oscillations in cuprate thin films, indicating the presence of a coupled collective mode, as well as a nonvanishing Higgs-like response at high temperatures, suggesting a potential nonzero pairing amplitude above Tc.

Perturbation of protein synthesis causes ribosome stalling on mRNAs. Here, Lehmann et al. demonstrate that the E3 ubiquitin ligase RNF10, through monoubiquitination of RPS3, promotes dissociation of the small ribosomal subunit upon ribosome stalling.

Plant-specific class III glutaredoxins regulate the activity of TGA transcription factors. Here, the authors show that that ROXY9, a member of the class III of glutaredoxins, lacks oxidoreductase activity due to unfavourable positioning of glutathione. Consequently, class III glutaredoxins may not regulate gene expression through redox modifications of target proteins.

Here the authors experimentally demonstrate a photonic quadrupole topological insulator in a photonic lattice, in which required synthetic π flux is induced by different symmetry representations of the orbitals in a mixed-orbital lattice.

IL-36 receptor is crucial for host defense and tissue repair. Here, the authors describe identification and characterization of low molecular weight inhibitors of the IL-36 receptor using encoded library technologies. This represents a rare example of small molecules inhibiting a member of IL-1 receptor family.

C-oligosaccharides are found in natural products and drug molecules, but their synthesis is challenging. Here, the authors report a strategy for the stereoselective and efficient synthesis of Coligosaccharides via palladium-catalyzed nondirected C1–H glycosylation/C2-alkenylation, cyanation, and alkynylation of 2-iodoglycals with glycosyl chloride donors.

The electrons and holes in a semiconductor can bind together to form excitons, which in turn couple together at higher carrier densities to create biexcitons. Here, the authors show, contrary to expectation, that biexcitons can outlive excitons at carrier densities close to the appearance of unbound electrons and holes.

The North Anatolian Fault Zone in Turkey has produced many large earthquakes, however the Marmara region has been inactive and is facing a high probability for a large earthquake. Here, Bohnhoff et al. report on a large seismicity gap in this area with implications for a seismic hazard for Istanbul.

TDP-43 aggregates are a hallmark of neurodegeneration. Wagner et al. show that SUMOylation/ubiquitylation of TDP-43, mediated by its recruitment to the promyelocytic leukemia protein nuclear bodies, prevents its aggregation under proteotoxic stresses.

Electrochemistry has emerged as an increasingly viable tool in molecular synthesis. Here the authors realize electrocatalyzed C−H activations, with the aid of data science and artificial intelligence, towards selective alkenylations for late-stage drug diversifications.

Similar to other eukaryotes, brown algae exhibit transcriptome conservation that is consistent with the molecular hourglass model during differentiation in embryonic development.

Studies on interferon-driven brain pathology have so far been hampered by the lack of appropriate animal models. Here the authors characterize RNASET2-deficient mice and show that neuroinflammation and brain atrophy are IFNAR1-dependent.

Stratified medicine promises to tailor treatment for individual patients, however it remains a major challenge to leverage genetic risk data to aid patient stratification. Here the authors introduce an approach to stratify individuals based on the aggregated impact of their genetic risk factor profiles on tissue-specific gene expression levels, and highlight its ability to identify biologically meaningful and clinically actionable patient subgroups, supporting the notion of different patient ‘biotypes’ characterized by partially distinct disease mechanisms.

Vaccines against SARS-CoV-2 have changed the course of the COVID-19 pandemics, but waning immunity necessitates repeated immunization. Authors here show that immunity declines faster following two doses of vector-based vaccine compared to a first dose of vector-based vaccine followed by boosting with an mRNA vaccine, but application of an mRNA vaccine as a third dose minimises the difference between the two groups.
