That is one big bacterium! Researchers have discovered a bacterium visible to the naked eye, challenging prevailing notions about the size of bacteria, most of which only can be seen when using a ...

Researchers found bacterial cells so large they are easily visible to the naked eye, challenging ideas about how large microbes can get. By Carl Zimmer In a Caribbean mangrove forest, scientists have ...

The fascinating world of bacteria that live as symbionts or parasites in animal hosts often remains a mystery to researchers. A research team has made a breakthrough that provides insights into this ...

Cheese fungus, head lice, human sperm, a bee eye, a microplastic bobble: scientific photographer Steve Gschmeissner has imaged them all under the probing lens of a scanning electron microscope (SEM).

Microscope Images of the bacteria P. acnes left untreated (A,B) or incubated for 24-hours (C,D) with resveratrol. Images were taken at 10,000x magnification (A,C) or 29,000x magnification (B,D).

This illustration represents a bacteria being illuminated with mid-infrared in the top left, while visible light from a microscope underneath is used to help capture the image. A team at the ...

Dutch scientist Antonie van Leeuwenhoek made extraordinary observations of blood cells, sperm cells and bacteria with his microscopes. But it turns out the lens technology he used was quite ordinary.
