Quantifying short-term evolutionary rates of microbial genomes is essential for understanding the processes that shape within-host evolution and for establishing thresholds needed to track transmissio...

Randomness is a powerful tool in the design and analysis of algorithms and data structures for nucleotide sequence data. Nucleotide sequences are not themselves random but are often randomized using hash functions. Despite their widespread use in genomics, there is no comprehensive review of the types of hash functions used and their various applications. In this survey intended for bioinformatic methods developers, we divide hash functions into four categories: scattering hash functions, permutations, minimum perfect hash functions, and locality-sensitive hash functions. For each category, we provide examples of both general-use hash functions that have been applied in nucleotide sequence analysis and hash functions that have been designed specifically for nucleotide sequence analysis. We highlight their salient properties, commonalities, differences, and application areas.

Blocking humanitarian organizations from accessing a medical breakthrough puts vulnerable people across the world in danger.

Gut colonization by the Gram-negative bacillus Klebsiella pneumoniae is a significant risk factor for extra-intestinal infections. However, the mechanisms by which this opportunistic pathogen causes d...

Richard Lenski traces the legacy of Escherichia coli and how science is evolving to use this model organism in new ways.

The absence of equipoise can turn research into harm

Glaciers are flush with microbial life. But, as climate change speeds glacial melting, scientists rush to establish microbial biobanks to preserve them.

Accumulating evidence has connected the chemically unstable, DNA-damaging gut bacterial natural product colibactin to colorectal cancer, including the identification of mutational signatures that are ...

With technological advances like single-cell sequencing and long-read sequence techniques continually improving, allowing the full resolution of increasingly complex highly repetitive genomes, and wit...

Here, the authors report within-host diversity and body site translocation dynamics in hospital samples of Pseudomonas aeruginosa and reveal that body site sharing was likely due to within-patient tra...

Abstract. Transformation occurs when bacteria import exogenous DNA via the competence machinery and integrate it into their genome through homologous recom

From populations of multicellular organisms to selfish genetic elements, conflicts between levels of biological organization are central to evolution. Plasmids are extrachromosomal, self-replicating g...

Bacterial immune systems have evolved in response to diverse molecular "parasites", yet their ecological roles remain poorly understood. This Essay explores how interactions between mobile genetic ele...
