Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study -- conducted using E. coli ...

The Krauter Lab probes the relationship between human microbial populations and human development and disease. They combine genetic analyses, environmental assessments and high-throughput DNA sequence ...

Marine bacteria in the wild organize into lifestyle groups that partition resources rather than competing for them, so that microbes with one lifestyle, such as free-floating cells, flourish in ...

Biologists from ETH Zurich have discovered speargun- like molecular injection systems in two types of bacteria and have described their structure for the first time. The special nanomachines are used ...
