Despite the diversity detected in Group A Streptococcus strains from more than 20 countries, investigators narrowed in on broadly shared sequences with relatively low variation.
Researchers identified 34 known and 30 new Leptospira species by sequencing dozens of isolates from soil and water samples in Asia, Africa, Europe, and Oceania.
Genetic material found in tooth samples from the Bronze Age, Iron Age, and Medieval period points to migrations from Siberia at the Bronze Age-Iron Age transition.
Genomic data for almost 300 ancient Eurasian horses points to lost equine lineages, horse relationships that reflect human interactions, and a recent loss in genetic diversity.
Based on sequences for hundreds of E. coli ST131 lineage isolates, researchers propose a model that involves negative frequency-dependent selection on accessory parts of the genome.
To understand the evolution of brain conditions and other traits, investigators plan to sequence human and pathogen DNA in thousands of samples from Europe.
Using genome sequences for 161 present-day Papuans and Island Southeast Asians, researchers described three Denisovan lineages and estimated divergence times between them.
Researchers found a potential alternative toxin, as well as antibiotic resistance genes, in a newly-sequenced Vibrio cholerae strain from a British WWI soldier.
Researchers retraced transmission events and resistance contributors with whole-genome sequences for 100 carbapenem-resistant Klebsiella pneumoniae isolates from a Beijing hospital.
The New York Times reports that researchers are combining tools to more quickly develop crops to feed a growing population and cope with shifting climates.
