A Microbial Hallowe'en, Part I

My mathematician wife "painted" onto a marine nutrient plate using a bioluminescent bacterium---as you can see, she loves Einstein. And I love microbiology. Hence the intersection! Read More

Supernova bacteria

Bacteria engineered to act as genetic clocks flash in synchrony. Here, a "supernova" burst in a colony of coupled genetic clocks just after reaching critical cell density. Superimposed: A diagram from the notebook of Christiaan Huygens, who first characterized synchronized oscillators in the 17t... Read More

Whole genome analysis of Chlamydia trachomatis highlights risks with current method of tracking

In a study released today in Nature Genetics, researchers have found that Chlamydia has evolved more actively than was previously thought. Using whole genome sequencing the researchers show that the exchange of DNA between different strains of Chlamydia to form new strains is much more common th... Read More

Pulsating response to stress in bacteria

By attaching fluorescent proteins to the genetic circuit responsible for B. subtilis's stress response, researchers can observe the cells' pulses as green flashes.

In response to a stressful environment like one lacking food, B. subtilis activates a large set of genes that help it respond to ... Read More
