The pheV Phenylalanine tRNA Gene in Klebsiella pneumoniae Clinical Isolates Is an Integration Hotspot for Possible Niche-Adaptation Genomic Islands
Horizontally acquired genomic islands may allow bacteria to conquer and colonize previously uncharted niches. Four Klebsiella pneumoniae tRNA gene insertion hotspots (arg6, asn34, met56, and pheV) in 101 clinical...

Open AccessA novelty-retrieval-extinction paradigm leads to persistent attenuation of remote fear memories
Exposure to a novel environment can enhance the extinction of recent contextual fear in mice. This has been explained by a tagging and capture hypothesis. Consistently, we show in mice that exposure to a novel...
