RNA methylation has recently identified as an important regulatory mechanism governing functional cellular states, but its effect on the antitumour activity of CD8 ⁺ T cells is not fully explored. Here authors assign an essential nuclear, m⁶A-recognition-dependent function to YTHDF2, which, in conjunction with its regulatory role in IKZF1/3-mediated gene transcription, governs anti-tumor activity in CD8 ⁺ T cells.

Histone crotonylation has been shown to regulate transcription in multiple settings, but its role during preimplantation development has not been examined. Here they show that P300 regulated crotonylation during embryonic development and that H3K18cr marks active promoters in embryos, crucial for transcriptional activation and embryonic fate determination.

Limited whole genome sequencing (WGS) of Asian populations results in a lack of representative reference panels, hindering imputation of Asian ancestry-specific genetic variants. Here the authors use WGS data from 11,067 individuals across 17 Asian countries to create a new reference panel which shows improved imputation accuracy for South Asian populations.

Two monoclonal antibodies isolated from a patient with COVID-19 are shown to interfere with SARS-CoV-2–receptor binding, and one displays potent action against this virus in vitro and in a rhesus macaque model.

Although the stereochemistry of nickel hydride addition to alkenes is well-explored, the analogous addition to another feedstock, alkynes, is less studied. Here the authors develop a regio- and enantioselective hydroalkylation of alkynes to produce chiral allylic amines, proceeding via migratory insertion of a nickel–alkyl species into an alkyne pi bond.
