Temperate and filamentous bacteriophages as reservoirs of bacterial virulence in stony coral tissue loss diseaseNARA Subscribed
Lysogenic conversion, in which bacteriophages (viruses that infect bacteria) integrate into bacterial genomes and confer new phenotypic traits on their hosts, is a well-established mechanism for the emergence of pathogens. While this process underpins many bacterial diseases in humans and other animals, its role in coral disease remains largely unexplored. Here, we investigate the potential role of lysogenic conversion in ston...
Human-camelid interactions and pastoral practices have shaped social, political, and economic lifeways throughout the history of the Central Andes. However, how camelids were managed in the central highlands during the Middle Horizon (600-1000 CE), and how those strategies reflect negotiations between Andean vertical ecologies, local communities, and the expanding Wari sphere, remain unclear. This study employed a life history...
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...
Distributed optical fibre sensing (DOFS) is a technology that enables continuous, real-time measurements of a range of environmental parameters along the length of a fibre optic cable. In this article, we review the recently emerged applications of DOFS techniques in physical oceanography and offer a perspective on the technology's potential for future growth within the field. The introduction of DOFS to physical oceanography...
Success of restoration strategies in preventing extirpation of 2 critically endangered coral speciesNARA Subscribed
An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral ( Acropora palmata ) and staghorn coral ( Acropora cervicornis ), were severely affected. These species have been the primary focus of reef restoration in Florida for decades. Substantial losses of these species occurred in outplanted populations, in o...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
Chronic Intermittent Hypoxia Exposure Induces a Unique Microglial Transcriptome in 5XFAD MiceNARA Subscribed
Clinical observations suggest that obstructive sleep apnea (OSA) and Alzheimer’s disease (AD) pathology may be linked; however, causal mechanisms and relationships are unclear. To investigate the potential interaction between amyloidosis and intermittent hypoxia (IH), a hallmark of OSA, starting at 4 months of age 5XFAD mice were exposed to chronic IH (CIH) consisting of 20 episodes per hour of hypoxia for 12 h/day, daily for...
Ocean acidification refers to a decrease in the pH of the world’s oceans from the oceanic uptake of human-derived atmospheric CO 2 . Low pH is known to decrease the calcification and survival of many calcifying invertebrates. Shallow, hard bottom communities along the Western Antarctic Peninsula often have incredibly large numbers of invertebrate mesograzers that shelter on and are mutualists with the dominant brown macroalgae...
The elkhorn coral, Acropora palmata , was historically a major reef-building species in the Caribbean, but has suffered devastating declines in recent decades. Despite significant restoration efforts in Florida, the marine heatwave of 2023 caused severe bleaching and mortality to both wild and restored colonies. To understand the disastrous impacts, we evaluated the variation in heat tolerance among Florida’s A. palmata popula...
