Like a major city, our cells use a complex transportation network to deliver molecular goods to different destinations. A protein called kinesin (blue) is in charge of moving cargo around inside cells and helping them divide. It's powered by biological fuel called ATP (bright yellow) as it scoot... Read More
This scanning electron micrograph (SEM) depicts a grouping of Vibrio vulnificus bacteria; Mag. 13184x.
Vibrio vulnificus is a bacterium in the same family as those that cause cholera. It normally lives in warm seawater and is part of a group of vibrios that are called "halophilic" because they ... Read More

Fernan Federici, a researcher in the Haseloff Lab at Cambridge University and one of the Synthetic Aesthetics residents, studies how cells grow and develop into complex shapes and structures. Using confocal microscopy, he tracks the growth of plant cells and tissues, creating models of how cell ... Read More
Microscopic view of a large numbers of Spirogyra filaments. (approx 100X). Taken from the Wistreich Collection, appearing exclusively in MicrobeWorld. Read More
Dictyostelium discoideum is a soil-living amoeba. A group of 100,000 form a mound as big as a grain of sand.
The hereditary information is carried on six chromosomes with sizes ranging from 4 to 7 Mb resulting in a total of about 34 Mb of DNA, a multicopy 90 kb extrachromosomal element that h... Read More

If we can visualize a protein's shape, we can learn much more about how it functions and how we might block its activity. This was the guiding principle behind an NIH initiative launched 25 years ago to spur the discovery of HIV-related protein structures. Structures produced through the program... Read More
This is a magnified view of an Arabidopsis thaliana leaf eight days after being infected with the pathogen Hyaloperonospora arabidopsidis, which is closely related to crop pathogens that cause 'downy mildew' diseases. It is also more distantly related to the agent that caused the Irish potato fa... Read More
Prosthogonimus macrorchis, a flatworm poultry parasite.
A digenetic trematode (family Prosthogonimidae) located in the oviduct and bursa fabricii of poultry in North America, particularly common in states bordering the Great Lakes. (http://www.medilexicon.com) Credit: Mr. Spike Walker

A new, nanometer-sized biosensor can detect a single deadly bacterium in tainted ground beef. How? Researchers attached nanoparticles, each packed with thousands of dye molecules, to an antibody that recognizes the microbe E. coli O157:H7. When the nanoball-antibody combo comes into contact with... Read More

This transmission electron micrograph (TEM) depicts some of the ultrastructural details displayed by H3N2 influenza virions responsible for casing illness in Indiana and Pennsylvania in 2011.
The cases of human infection with swine-origin H3N2 influenza resulted from existing influenza virus... Read More

In this Envisat image, a phytoplankton bloom swirls a figure-of-8 in the South Atlantic Ocean about 600 km east of the Falkland Islands.
During this period in the southern hemisphere, the ocean becomes rich in minerals from the mixing of surface waters with deeper waters. Phytoplankton depen... Read More
A protein called tubulin (green) accumulates in the center of a nucleus (outlined in pink) from an aging cell. Normally, this protein is kept out of the nucleus with the help of gatekeepers known as nuclear pore complexes. But NIGMS-funded researchers found that wear and tear to long-lived compo... Read More
Borrelia burgdorferi is a spirochete, a class of long, slender bacteria that typically take on a coiled shape. Infection with this bacterium causes Lyme disease.

What looks like a Native American dream catcher is really a network of social interactions within a community. The red dots along the inner and outer circles represent people, while the different colored lines represent direct contact between them. All connections originate from four individuals... Read More
