This past weekend the USA Science and Engineering Festival came to Washington, D.C. The American Society for Microbiology and MicrobeWorld were present with our own booth in which we offered several microbe-related activities for attendees of all ages.
In this picture, Barbara Hyde, director... Read More

We celebrated the 200th episode of TWiV by visiting the National Emerging Infectious Diseases Laboratories at Boston University Medical Center, where we met with Elke, Paul, and Ron to talk about building and working in a BSL4 facility. It was an amazing visit that will be fully documented in an... Read More

Confocal micrograph showing Shigella bacteria (pink) invading the intestinal lining. The bacteria infects the cells by high-jacking the cell's internal actin skeleton (green) to facilitate its entry into the cell and spread into adjoining cells, using polymerizing actin comet tails as several ca...

A quick demonstration of how my Microbial Mania can impact the holiday season! Read More
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
Cytomegalovirus in human foreskin tissue cells (40x) Acridine orange stain. Darl, olive green bodies in refractile cells are intranuclear inclusions. Also show paranuclear bodies which are stained darker Read More

A particular type of ancient rock art in Western Australia maintains its vivid colours because it is alive, researchers have found.
While some rock art fades in hundreds of years, the "Bradshaw art" remains colourful after at least 40,000 years.

This transmission electron micrograph (TEM) depicted a number of Nipah virus virions that had been isolated from a patient's cerebrospinal fluid (CSF) specimen.
Nipah virus is a member of the family Paramyxoviridae, and is related, but not identical to Hendra virus. Nipah virus was initially ... Read More
B. cereus was grown on urea agar for 6 days at 37 degrees C to induce spore formation.
The endospore stain was done using malachite green as the primary stain and safranin as counter the stain. Malachite green was applied to the smear and set over a steaming water bath for 10 min (stain was no... Read More
Microscopes have been around for some 400 years, and today they are even accessible via customized cell phones. The act of peering into a microscope of any power can open a whole world of life and beauty that exists right under (or in) our noses. And to capture that rare view for reproduction ca... Read More
Möbius strips are special loops that only have one continuous side. Now we've built the smallest Möbius strips ever - out of DNA. Here you can see the nanometer-sized DNA loops, folded like origami.
The ability to create complex structures on the tiniest of scales is one of the great challeng... Read More
The presence of green algae colonizing the air space. From the Wistreich Collection. Read More
A colorized electron microscope image captures delicate chains of streptococcus in a laboratory sample. Though some strep infections can be deadly, many strains are harmless—among the thousands of benign beings that make their home in our bodies.

Honorable Mention for Illustration: NSF 2004 International Science & Engineering Visulization Challenge
X-ray crystallographic data was used from real DNA molecules to paint a unique portrait of the double helix. The image omits the chemical bonds that crisscross the center of the molecule, s... Read More
