    We squeezed together under a small roof near the guard station just outside of the White House to avoid the drenching rain. There was excitement in the air as we waited for the launch of The National Microbiome Initiative (https://www.whitehouse.gov/blog/2016/05/13/announcing-national-microbiome-... More...

  • Quality Annotations, a Key Frontier in the Microbial Sciences
    Image of Author: Valérie de Crécy-Lagard

    For microbiologists, the sequencing of the genome of the bacterium in 1995 was a pivotal event, one that transformed the microbiological research enterprise. More than 20 years later, with the genomes of some 85,000 organisms sequenced, includ... More...

  • Whole-Genome Sequencing Is Taking over Foodborne Disease Surveillance
    Image of Authors: Heather A. Carleton and Peter Gerner-Smidt

    About 1 in 6 people are sickened with foodborne diseases each year, and for the most part those illness bouts are a nuisance and self-limiting. However, for some vulnerable populations, severe foodborne illnesses can require hospital care and may even lead to death. Once an individual becomes sic... More...

  • Bacterial Diversity Is Dominant Feature in New Tree of Life
    Image of Author: Carol Potera

    A new rendition of the tree of life includes 92 named bacterial phyla, 26 archaeal phyla, and all five of the eukaryotic supergroups. This tree highlights how bacteria dominate all of biology in terms of diversity. Moreover, although many of the most abundant bacteria have never been seen, they w... More...

  • New Synthetic Cell Challenges One-Gene, One-Trait Hypothesis
    Author: Marcia Stone

    “Life is much more like a symphony orchestra than a piccolo player,” J. Craig Venter says about his institute's new synthetic bacterium. It carries a mere 473 genes, a smaller genome than any autonomously replicating cell ever found in nature. That Venter and his collaborators synthesized a ... More...
