This montage of tiny, transparent C. elegans—or roundworms—may offer insight into understanding human infertility. Researchers used fluorescent dyes to label the worm cells and watch the process of sex-cell division, called meiosis, unfold as nuclei (blue) move through the tube-like gonads. Such... Read More
Helicobacter pylori (yellow), a common bacterium that lives in the stomach lining, increases the risk of stomach cancer (brown cells) and peptic ulcers. But over time H. pylori can reduce stomach acid and acid reflux, which may help fend off esophageal cancer. The microbe also appears to help pr... Read More
This thin section transmission electron micrograph (TEM) depicts numerous virions revealed in a preparation of HIV (human immunodeficiency virus).
HIV is the virus that can lead to acquired immune deficiency syndrome, or AIDS. CDC estimates that about 56,000 people in the United States contract... Read More

“Predator” bacteria (green) surround “prey” bacteria (red) in this petri dish version of the Serengeti. Rather than eating their prey, however, predator cells release a chemical that activates a suicide gene in the prey. Prey cells also release a chemical, but one that promotes survival of the p...

Two worm sperm shimmy across a microscope slide. Unlike most cells that rely on motor proteins to propel themselves forward, worm sperm use tiny fibers at their front ends. Putting the fibers together and taking them apart sets the cells in motion. In a new advance, researchers disassembled the ... Read More
Microscopes have been around for some 400 years, and today they are even accessible via customized cell phones. The act of peering into a microscope of any power can open a whole world of life and beauty that exists right under (or in) our noses. And to capture that rare view for reproduction ca... Read More
An alternate view of amoebae fruiting bodies, with spores and bacteria. Related Story: Like Humans, Amoebae Pack a Lunch Before They Travel.
Some amoebae do what many people do. Before they travel, they pack a lunch.
In results of a study reported today in the journal Nature, evolutionary ... Read More
Möbius strips are special loops that only have one continuous side. Now we've built the smallest Möbius strips ever - out of DNA. Here you can see the nanometer-sized DNA loops, folded like origami.
The ability to create complex structures on the tiniest of scales is one of the great challeng... Read More

Marine bioluminescent Photobacterium kishitanii
The genus Photobacterium was first coined by Martin Beijerinck, in 1889, and originally referred to all bacteria capable of light production. Species belonging to Photobacterium are gram negative, rod shaped, chemoorganotrophic, facultative aerob... Read More
