Bacteria span Earth’s ecosystems, coupling ecological versatility with genome-architectural reconfiguration across shifting physicochemical conditions. Yet the genomic routes by which free-living lineages cross ecosystem boundaries, and the consequences for genome architecture, remain poorly understood.

Genome annotation currently requires performing dozens of molecular assays in hundreds of cell and tissue samples, an expensive endeavor which is impractical to replicate across all species and conditions of interest. Here, we introduce BioSeq2Seq, a deep learning framework that infers cell-line-specific molecular assays widely used for genome annotation by leveraging a tri-modal input: evolutiona...

The research explores how extracellular vesicles (EVs) and their microRNA cargo serve as a critical communication bridge between the immune system and the brain to regulate social behavior. Scientists discovered that transferring blood-borne EVs from healthy mice into models with social deficits, such as immunodeficient Rag1-/- mice, successfully restored normal sociability levels. These EVs trave...

The basal ganglia integrate cortical inputs with dopaminergic signals to potentiate and select actions. The reward-related activity of dopamine neurons is well-studied, but the coding properties of cortical inputs to the basal ganglia remain largely unknown. We examined the activity of neurons in the frontal eye field of monkeys that were optogenetically identified as projecting to the basal gangl...

This research outlines a comprehensive spatial tumor evolution panorama of high-grade serous ovarian cancer using the innovative STARLETS framework.
