This video explores the ways in which humans are learning to exploit microbes to produce medicines, fuel and food.
Under a magnification of 3841X, this scanning electron micrograph SEM) revealed some of the ultrastructural morphologic details exhibited by a number of Gram-positive bacilli, or “rod-shaped”, Mycobacterium fortuitum bacteria.
M. fortuitum is classified as a “rapidly-growing” Mycobacterium, ... Read More
On the issue of antibiotic-resistant bacteria and animals, the first thing that comes to mind is livestock and other farm-based animals that are regularly fed antibiotics as growth promoters, but they are not the only source of resistance. Participants discuss studies showing that non-farm anim... Read More
A recent study by researchers at the University of Hawaii, Manoa, and the Oregon State University provides strong evidence that mitochondria share a common evolutionary ancestor with a lineage of marine bacteria known as SAR11, arguably the most abundant group of microorganisms on Earth.

Collaborative investigation efforts of state, local, and federal public health agencies indicate that a frozen raw yellowfin tuna product, known as Nakaochi Scrape, from Moon Marine USA Corporation is the likely source of this outbreak of Salmonella Bareilly infections. Nakaochi Scrape is tuna b... Read More
The human vagina is a lively place, full of beneficial bacteria that discourage nasty microbes from invading. Now, new research finds this ecosystem is even more mysterious than previously realized.
Not only do women vary widely in what sorts of microbes call the vagina home, the study finds,... Read More
In order to survive in complex and interesting environments in the wild, bacteria have a whole arsenal of chemical products that they make within the cell. These chemicals are used for signalling, defence and communication between bacterial cells. One particular group of these chemicals is calle... Read More
Okay, here’s the deal. You and your pals — grad students, hotshot scientists-to-be — are invited to Hawaii to talk about cutting-edge jobs in microbiology. But after you learn that the company’s owner is a crook and a killer, he uses his new technology to shrink you from six feet tall to half an... Read More
This episode: Bacteria and predacious fungi work together to trap nematodes!
Researchers have determined that bacteria are present in the bladders of some healthy women, which discredits the common belief that normal urine is sterile. These findings were published in the April issue of the Journal of Clinical Microbiology by researchers at Loyola University Chicago Strit... Read More
All life on Earth relies on a standard set of 20 molecules called amino acids to build the proteins that carry out life's essential actions. But did it have to be this way?
All living creatures on this planet use the same 20 amino acids, even though there are hundreds available in nature. Sci... Read More
Once upon a time, tasters were employed by the well-to-do, in order to check that their food or drink wasn't poisonous. Today, there are electronic biosensors that can do more or less the same thing. Unfortunately, as was no doubt sometimes the case with the tasters, the biosensors can’t always ... Read More
