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
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
This episode: Sampling storm cloud microbial communities with hailstones!
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
This episode: Using glowing bacteria to image tumors in the body!
The human microbiome consists of thousands of viral and microbial species which inhabit the human body and have co-evolved with us to protect against pathogens, regulate organ function and supply nutrients and other factors essential for health. When these members fall out of balance, it can le... Read More
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
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
