Execution of mRNA cleavage in nonsense-mediated decay remained elusive. The authors show that SMG5 complements SMG6 to form a highly active, composite endonuclease with expanded catalytic center that enables regulated substrate cleavage.

Florets of indica rice open earlier than japonica rice, hindering utilization of the cross subspecies heterosis. Here, the authors show that an OsMYB8-OsJAR1 module regulates diurnal floret opening time divergences between the two subspecies.

Kir7.1 is an essential potassium channel. The authors report cryo-EM structures in multiple states revealing how bioactive lipids modulate Kir7.1, and define a pharmacological landscape that identifies agonists with therapeutic potential.

ATF6α activation in human and preclinical models of hepatocellular carcinoma is significantly associated with an aggressive tumour phenotype characterized by reduced survival, glycolytic reprogramming and local immunosuppression.

Patients with myelodysplastic syndromes (MDS) have limited therapeutic options. Here the authors show that functionally impaired NK cells contribute to immune escape of pre-malignant clones in early stage MDS and that NK adoptive cell therapy can be considered to prevent or delay the development of MDS.

An Earth system model estimates that natural halogens, of marine biotic and abiotic origin, remove about 13% of present-day global tropospheric O₃. Projections suggest this ratio is stable through 2100, with high spatial heterogeneity, despite increasing natural halogens.

In a case series of eight pediatric patients with systemic lupus erythematosus, dermatomyositis or systemic sclerosis, autologous anti-CD19 CAR T cell therapy was feasible, safe and effective in reducing disease activity.
