A colour-enhanced scanning electron micrograph image showing a cluster of Clostridium difficile on a surface. Clostridium difficile is a species of Gram-positive bacteria that causes severe diarrhea and other intestinal disease when competing bacteria in the gut flora have been wiped out by anti... Read More
I'm greatly concerned about the harmful effects of nanotechnology. I'm old, but have grand kids, who already have to live with all kinds of junk in the environment. I guess it's a topic that fits in the virology category, too, since are not nanotech-sized parti... 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
Cell showing overproduction of the ARTS protein (red). ARTS triggers apoptosis, as shown by the activation of caspase-3 (green) a key tool in the cell's destruction. The nucleus is shown in blue.

Snottites have captivated cave-goers and scientists alike since the earliest publication on cave microbes by Hoeg in 1946. These biofilms cover the walls with a thick snot-like film, from which they derive their particularly appropriate name. A variety of cave systems, the Frasassi caves in Ital... Read More
Just listened to this weeks twiv, and the q dot dyes you mentioned are also used in electronics. There they are used as a ultra precise phosphor. In that application blue light from LEDs can be re-emitted as red, an... Read More
Introduction and uses of culture media for growing pathogenic bacteria and fungi
This sculpture made of purple and clear glass beads depicts bacteriophage Phi174, a virus that infects bacteria. It rests on a surface that portrays an adaptive landscape, a conceptual visualization. The ridges represent the gene combinations associated with the greatest fitness levels of the vi... Read More
This episode: Some bacteria have been discovered that construct multiple types of magnet in their cells!
Do you plan to do any promotion of an #asv2012 hashtag for the meeting in Madison this year? I remember some limited tweeting from Minneapolis last year (in between melting into the sidewalk) but I think TWiV would be a great way to promote it ahead of ti... Read More
Vincent Racaniello accepts the Peter Wildy Prize for Microbiology Education, awarded annually by the Society for General Microbiology for an outstanding contribution to microbiology education. Filmed at the Dublin Convention Centre in Dublin, Ireland. Read More
A number of variables can cause signficant changes in the human microbiome early in life including birth method and antibiotic exposure. Understanding these shifts is important because new research suggests that shifts in the microbiome of infants could make them more prone to gain weight as adu... Read More
Scientists have managed to reverse type 1 diabetes (T1D) in experimental mice by giving the animals an oral course of harmless gut bacteria that had been engineered to secrete the whole proinsulin autoantigen (PINS) and the immunomodulatory human cytokine IL-10 (hIL10). An international team led... Read More
