One of many varieties of colorful lichens that grow on Ocotillo along the coast of Baja, Calif.
Lichens are actually made up of two plants: an algae and a fungus, living in a symbiotic relationship. In desert environments, lichen will dry out completely and remain dormant until rain or dewfal... Read More
To help scientists understand how the Penicillium stoloniferum virus interacts with its hosts, and how it replicates and matures over its lifecycle, the virus structure was solved at the very high-resolution of 7.3 angstroms. Running the automated AUTO3DEM software on a San Diego Supercomputer C... Read More

Marburg hemorrhagic fever (Marburg HF) is a rare, severe type of hemorrhagic fever which affects both humans and non-human primates. Caused by a genetically unique zoonotic (that is, animal-borne) RNA virus of the filovirus family, its recognition led to the creation of this virus family. The fi... Read More

The Gram-positive bacteria Staphylococcus epidermidis and Staphylococcus aureus are the most common pathogens in hospital-acquired infections. The costs related to infections caused by these strains in the hospital setting are enormous and represent a major healthcare burden. Furthermore, the mo... Read More

Campylobacter bacteria are the number-one cause of food-related gastrointestinal illness in the United States. To learn more about this pathogen, ARS scientists are sequencing multiple Campylobacter genomes. This scanning electron microscope image shows the characteristic spiral, or corkscrew, s... Read More
This microscopy image provided by Dr. Carl June, shows immune system T-cells, center, binding to beads which cause the cells to divide. The beads, depicted in yellow, are later removed, leaving pure T-cells which are then ready for infusion to the cancer patients. Scientists are reporting the fi... Read More

Colorized transmission electron micrograph of Avian influenza A H5N1 viruses (seen in gold) grown in MDCK cells (seen in green).
Avian influenza A viruses do not usually infect humans; however, several instances of human infections and outbreaks have been reported since 1997. When such infecti... Read More
