There have been over 60 human infections with avian influenza virus H7N9 in China, and cases have been detected outside of Shanghai, including Beijing, Zhejiang, Henan, and Anhui Provinces. Information on the first three cases has now been published, allowing a more detailed consideration of the... Read More
Does a bacterium’s cell wall, shape, way of moving, and environment really matter?
Yes! The more we know about bacteria, the more we are able to figure out how to make microbes work for us or stop dangerous ones from causing serious harm. And, for those of us who like to ponder more philosop... Read More

A new data resource for measuring the accuracy of metagenomic binning methods, created by in vitro-simulation of a metagenomic community, can be used to complement previous in silico benchmark studies. In constructing a synthetic community and sequencing its metagenome, researchers from the Univ... Read More

Microbes can tailor transcriptional responses to diverse environmental challenges despite having streamlined genomes and a limited number of regulators. We present data‐driven models that capture the dynamic interplay of the environment and genome‐encoded regulatory programs of two types of prok... Read More
When viruses come into contact with host cells, they trigger the cells to engulf them, or fuse themselves to the cell membrane so they can release their DNA into the cell.
Once inside a host cell, viruses take over its machinery to reproduce. Viruses override the host cell’s normal functioni... Read More
Researchers examined samples from the brains of patients with and without dementia and found lipopolysaccharide, a component of Porphyromonas gingivalis, an oral bacterium, in four out of 10 Alzheimer’s disease brain samples.
“This clearly shows that there is an association between oral bacte... Read More
