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
Prosthogonimus macrorchis, a flatworm poultry parasite.

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
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
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

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
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
Shiga toxin is an extremely potent toxin that is produced when the bacterium contains a bacteriophage carrying the toxin gene. It is closely linked with Haemolytic Uraemic Syndrome and acute renal failure in children. After ingestion via contaminated food or water the E. coli bacteria colonize t... Read More
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

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

Note the wheel-like appearance of some of the rotavirus particles. The observance of such particles gave the virus its name ('rota' being the Latin word meaning wheel). Bar = 100 nanometers. Rotaviruses are nonenveloped, double-shelled viruses, making the virus stable in the environment.
