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 ...

Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.

Toxins on poison dart frog skin mold the skin's microbial community, boosting species variety and potentially even feeding some daredevil bacteria.

Bacteria reproduce at regular intervals. An example might be every 20 minutes. This allows mathematical calculations to be made in order to predict how many bacteria will be present in a given ...
