entities that could cause an infection and pass through a filter small enough to exclude almost all bacteria. While the size of Mimivirus certainly stretches our common perceptions of viruses ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...

However, as a bacterial colony develops, “growing pains” are inevitable, as proliferating cells must balance growth rates with the stress of overcrowding and nutrient resource limitations. Other ...
