Giardia protozoan

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

Bacteria biofilm

This confocal micrograph, taken as part of a synthetic biology project, shows Bacillus subtilis, a Gram-positive, rod-shaped bacterium that is commonly found in soil. Distinct lineages of bacteria expressing different fluorescent proteins were initially mixed randomly on a petri dish. As the bac... Read More

Strange Biology Inspires the Best New Materials

From the shiny, strong nacre that gives abalone shells an unbreakable, opaline sheen, to the goopy mix of proteins fired by a velvet worm that solidify and trap prey upon impact, nature is packed with inspiration for scientists designing new materials.

Waterproof adhesives and self-cleaning s... Read More

Pictures Considered. The E. coli Chromosome Caught in the Act of Replicating

We continue our series of images that have made a difference in microbiology. This one, published by John Cairns in 1963 has earned a most deserved place in textbooks and reviews. It shows a radioautograph of an intact E. coli chromosome in the act of replicating. From this image, Cairns conclud... Read More

Bacterial colonies lend whole new meaning to "smartphone culture"

A relatively straightforward classroom experiment produces fascinating images by students at the University of Surrey when they imprinted their smartphone onto a bacterial growth medium. Read More

Tapeworm Echinococcus granulosus Hydatid Cyst

Echinococcus granulosus is a tapeworm parasite that in its larval form can cause hydatid disease, which is characterized by cysts forming within the victim's body. In order to complete its lifecycle, the tapeworm must infect two hosts, a carnivore and a herbivore.

The adult form of Echinococc... Read More
