How an experience results in a long-term memory has remained unknown. A circuit involving the posteromedial nucleus of the cortical amygdala in the brain is shown to consolidate memories for socially transmitted food preferences in mice using a gene-transcriptional mechanism without contributing to memory acquisition, storage or retrieval.

Many diseases arise from the misplacement of proteins in cells. A potential solution to this problem has been developed: small molecules that help displaced proteins catch a ride with other proteins to return to their proper location.

Differences in gene expression between individuals are an important source of variation in traits and diseases. However, most of the research into such differences in humans has focused on individuals of European ancestries, limiting its generalizability. A geographically diverse, open-access gene-expression resource now enables the exploration of variation of gene expression in under-represented populations.

Swirling magnetic structures move through a material in ways that depend on their interactions with mobile electrons. Fresh insight into how to control this electrodynamic effect could lead to ultracompact magnetic devices.
