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

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

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

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

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

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

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

Snottites have captivated cave-goers and scientists alike since the earliest publication on cave microbes by Hoeg in 1946. These biofilms cover the walls with a thick snot-like film, from which they derive their particularly appropriate name. A variety of cave systems, the Frasassi caves in Ital... Read More

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
