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
Cell showing overproduction of the ARTS protein (red). ARTS triggers apoptosis, as shown by the activation of caspase-3 (green) a key tool in the cell's destruction. The nucleus is shown in blue.

Colorized scanning electron micrograph of rust on a rose leaf. Rose rust is a disease specific to roses and is caused by the parasitic fungus Phragmidium tuberculatum and some other closely related species. This disease occurs during spring and persists until the leaves fall. This images shows r... Read More
This is a live image of the of Diatom Arachnoidiscus under 40x magnification. The picture shows the diatom's silicified cell wall, which forms a pillbox-like shell (frustule) composed of overlapping halves that contain intricate and delicate markings. The picture was obtained with new video enha... Read More
Photomicrograph of Chlamydia grown in culture. The sample was taken from rhesus monkey kidney cells and stained with giemsa. The cell nuclei appear red and the infective 'elementary bodies' of the Chlamydia, which develop in 'blisters' in the cells, fluoresce green. Chlamydia is a very common se... Read More
This image of laboratory-grown cells was taken with the help of a scanning electron microscope, which yields detailed images of cell surfaces.

View an interactive animation of the life cycle of the malaria parasite, of the genus Plasmodium. The lifecycle of the malaria parasite is split between female mosquitoes and humans. In the mosquito gut, the parasites complete sexual reproduction and then multiply rapidly to produce many more p... Read More

This tropical scene, reminiscent of a postcard from Key West, is actually a petri dish containing an artistic arrangement of genetically engineered bacteria. The image showcases eight of the fluorescent proteins created in the laboratory of Roger Y. Tsien, a cell biologist at the University of C... Read More
