Precise structure and polarization determination of Hf_0.5Zr_0.5O₂ with electron ptychography

Using multislice electron ptychography, the authors precisely resolve oxygen positions in freestanding Hf_0.5Zr_0.5O₂, quantify its ferroelectric polarization, reveal strong suppression at grain boundaries and observe an atomic-scale head-to-head charged domain wall.

Mitigating the missing-fragmentation problem in de novo peptide sequencing with a two-stage graph-based deep learning model

Identifying unknown peptides in tandem mass spectrometry is challenging as fragmentation of precursor peptides can be incomplete. Mao and colleagues present a method based on graph neural networks and a path-searching model to create more stable sequence predictions.

Synthetic libraries of immune cells displaying a diverse repertoire of chimaeric antigen receptors as a potent cancer immunotherapy

Synthetically generated and clonally expanded libraries of immune cells displaying diverse repertoires of chimaeric antigen receptors lead to long-lasting and potent antitumour responses in mouse models of epithelial tumours.

Calcium/calmodulin-dependent protein kinase IV promotes imiquimod-induced psoriatic inflammation via macrophages and keratinocytes in mice

Calcium/calmodulin-dependent protein kinase IV (CaMK4) has been shown to be involved in autoimmunity but it is not clear how it functions in psoriasis. Here the authors show that CaMK4 is increased in psoriasis and promotes inflammatory responses in mouse models of psoriasis mediated through macrophages and keratinocytes.

Highly efficient ethylene production via electrocatalytic hydrogenation of acetylene under mild conditions

This work achieves highly active and selective electrocatalytic hydrogenation of acetylene to ethylene (HAE) under mild conditions over Cu catalyst to replace the classic thermocatalytic HAE route requiring harsh conditions and costly H₂.
