Researchers have discovered the largest virus ever, and they've given it a terrifying name: Pandoravirus.
A typical virus is a tiny sack of genetic material that injects itself into a much larger cell and uses it to make more viruses. The Pandoravirus is enormous by comparison—large enough to... Read More

In a healthy adult human body, most internal organs such as the brain, spleen, liver, and heart are devoid of microorganisms because the immune system keeps them in check. After human host death, however, the immune system falters and microorganisms proliferate throughout the body beginning in ... Read More

Young sibling polyps of staghorn coral (Acropora millepora) three days after settlement. In a National Science Foundation-supported study, researchers found that the ability to fluoresce may influence whether or not the coral settle on the reef of their origin or disperse, and go elsewhere.

This digitally-colorized scanning electron micrograph (SEM) depicted the dorsal (upper) surface of a Giardia protozoan that had been isolated from a rat’s intestine. Some of the identifying morphologic characteristics include pairs of thread-like flagella that facilitate motility, and a ventolat... Read More
