Using haplotype profiling, phylogenetics, and other analyses, researchers retraced sickle allele emergence to a single event occurring roughly 7,300 years ago.
While the virus they found appears old, the researchers found it to be closely related to modern ones, indicating that it has infected people for centuries.
By sequencing Vibrio cholerae isolates from Africa and Latin America, investigators got a look at the lineages leading to outbreaks over several decades.
With hundreds of bacterial genome sequences, researchers characterized horizontal gene transfer hotspots contributing to genome evolution and diversification.
Researchers sequenced and analyzed the genome of Apostasia shenzhenica, which is part of a small sister lineage to other plants in the Orchidaceae family, uncovering new evolutionary clues.
The Associated Press reports that the US Centers for Disease Control and Prevention is beefing up sequencing as a tool to investigate foodborne illnesses.
