Long dismissed as featureless, disorganized sacks, bacteria are now revealing a multitude of elegant internal structures. Ewen Callaway investigates a new field in cell biology. Nearly a decade ago ...

Bacteria may seem like pretty simple lifeforms, but their ingenuity keeps surprising scientists. The latest example is a species called Geobacter sulfurreducens, which has now been found to survive ...

The number of resistant strains has increased, partly due to the misuse of antibiotics. This has resulted in more infections that are difficult to control. MRSA is methicillin-resistant staphylococcus ...
