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.

The mechanisms underlying neuron specification and maturation are unclear. Here the authors provide an integrated epigenomic and transcriptomic analysis of mouse and marmoset neocortical neuronal classes. Pan-neuronal programs active during early development are more evolutionary conserved but not neuron-specific, whereas pan-neuronal programs active during later stages of maturation are more neuron- and species-specific.

A mapping between emotions and speech prosody is commonly assumed. This study shows, using Bayesian modelling, that differences across individuals, cultures and sexes contribute more to the model prediction than a shared global mapping.

How RNA-binding proteins (RBPs) regulate gene expression via effectors of RNA processing is unclear. Here, the authors dissect the effector interface of an essential RBP, Unkempt, and investigate its contribution to translational control in cells.

Kinase inhibitors are widely used to treat cancer, however patients frequently develop resistance. Here, the authors investigate adaption mechanisms during drug persistence and show that stimulation of the innate immunity sensor RIG-I enhances cancer cell death when combined with kinase inhibition.

Cognitive function is associated with health and important life outcomes. Here, the authors perform a genome-wide association study for general cognitive function in 300,486 individuals and identify genetic loci that implicate neural and cell developmental pathways in this trait.
