Artist Sonja Bäumel explores the skin microbiome in her project Cartography of the Human Body. Bacteria isolated from Bäumel’s skin were characterized and grown individually, then used to reconstruct an artificial microbiome with many layers of differently-colored species. Giant petri dishes gre... 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
Germaphobes, maybe you're on to something.
Sickness-causing bacteria and viruses can lurk on surfaces long after they're expelled in an infected person's sneeze or snot. Some can even stay on a surface for months, given the right conditions. While the ability of these microorganisms to actual... Read More
This basic lab-training image was captured from the wall sticker of Clinical Microbiology Laboratory, Department of Veterinary Disease Biology, Faculty of Health and Medical Sciences, University of Copenhagen, Denmark. Read More
Bioluminescent art blends science and creativity to create images that can only be seen in the dark. What do you get when you add a chemical engineer, a graphic designer and a research scientist? Beautiful art. In a wondrous combination of nature and design, bioluminescent art involves using nat... Read More
BOSTON, Aug. 18, 2015 -- When a fever strikes in a developing area, the immediate concern may be: Is it the common flu or something much worse that requires quarantine? To facilitate diagnosis in remote, low-resource settings, researchers have developed a paper-based device that changes color, d... Read More
Unknown yeast isolated on TSA from a swab taken from the bottom of a shoe incubated at 25 degrees C. Yellow, mucoid, round colonies were seen after 2 weeks. This isolate grew equally well at 37 degree C with a growth time of ~ 1 week. Read More

For the first time in more than a year, Guinea passed a week without a new lab-confirmed Ebola case, but the news out of West Africa last week was tempered by a flare-up of activity in Sierra Leone, the World Health Organization (WHO) reported today in its latest update. Read More
Pseudomonas aeruginosa is one of the most notorious organisms that have brought the therapeutic dilemmas to clinicians as well as challenge to microbiologist throughout the world. It carries gene of intrinsic resistance (AmpC cephalosporinase, the OprD outer membrane porin, and the multidrug ef... Read More

Inspired by the current Agar Art Contest and the gorgeous red of a recently isolated Serratia, I thought I'd try out my first bacteria "sketch." Using Serratia, Citrobacter, and an E. coli on Hektoen Agar I whipped up this goey DNA double helix! Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More

Immune cells that hang around after parasitic skin infection help ward off secondary attack, according to a study in The Journal of Experimental Medicine. These skin squatters may prove to be the key to successful anti-parasite vaccines. Read More
Unknown Yeast or Bacteria seen on tip of finger print grown for 2 days at 37 degrees C then held at room temperature for 3 days. Organism was yellow, mucoid, raised rhizoid with large holes. Read More
Serratia marcesens is a Gram-negative, rod-shaped bacterium that is commonly found in soil, water, on plants and in animals and thrives in damp conditions. This organism is well known for its production of the blood red pigment, prodigiosin. Production of prodigiosin can be influenced by several... 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.

My wife Jennifer Quinn hits it out the park: a portrait of Kenneth Nealson and the late Woody Hastings "painted" with luminous bacteria, giving them props for the early days of quorum sensing---where the basic principles were first uncovered in bioluminescent microbes. This principle of "aut... Read More
