How Did a Size‐Divergent Water Strider Species Group Exhibiting an East Asia–Eastern North America Disjunction Originate and Diversify?NARA Subscribed
The classic East Asia–Eastern North America (EA‐ENA) disjunction, well‐documented in temperate plants, is typically attributed to the fragmentation of once‐continuous high‐latitude ranges by climatic cooling and regional extinction. Whether this model extends to insects, particularly aquatic groups, remains largely untested with genomic data. Here, we integrate whole‐genome sequencing, ddRAD‐seq and morphology with phylogeneti...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
