COLD SPRING HARBOR, NY (GenomeWeb) — By tracing mutations in hypermutable polyguanine repeats located in intergenic regions, researchers have been able to reconstruct the phylogenies of patients' cancers, giving insight into how metastases develop.
NEW YORK (GenomeWeb News) – A study appearing online today in Nature suggests that convergent evolution at hundreds of sites across the genome has helped animals in at least three mammalian lineages acquire the ability to navigate with the help of sound.
NEW YORK (GenomeWeb News) – A bevy of studies appearing this week in Nature Genetics traced the evolution of the tuberculosis-causing bacterium from its pre-Neolithic roots to today's modern, and increasingly drug-resistant, strains.
NEW YORK (GenomeWeb News) – Through a phylogenetic analysis, researchers in the UK have traced the origin of human cases of community-acquired methicillin-resistant Staphyloccosus aureus to strains circulating in cow
NEW YORK (GenomeWeb News) – The cholera strain behind the outbreak that emerged in Haiti in 2010 has a limited ability to acquire new genes, according to an evolutionary analysis of isolate genomes conducted by Cheryl Tarr at
A polar bear phylogeny based on hundreds of mitochondrial DNA sequences from polar and brown bear samples from as far back as about 120,000 years ago hints at a shared maternal ancestry for modern polar bears and Irish brown bears.
By combining genetic, antigenic, and epidemiological data from a Hong Kong slaughterhouse with data on samples collected since the 1970s, researchers have gained new insights into the evolution and transmission of swine influenza A viruses.
