For a holiday card, my wife and I made a Christmas Tree with bioluminescent ornaments. The video shows how the tree looks in natural light, and then by its own light. The bacterium is Photobacterium leiognathi, isolated by Ned Ruby and Eric Stabb in Hawai'i. This is another example of where mi... Read More
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
David Tuller, health journalist and Berkeley faculty member, has written a piece on the CDC's handling of CFS. His account draws from interviews, a close reading of a fraction of the 4608 epidemiologic studies that pop up on a PubMed search for “chronic fatigue syndrome,” and a review of many pa... 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 as little as 100 generations, yeast selected to settle more quickly through a test tube evolved into multicellular, snowflake-like clusters, according to a paper published in Proceedings of the National Academy of Sciences. Over the course of the experiment, the clusters evolved to be larger,... Read More

Bacteria and other microbes love living in slimy communities that cling to riverbed rocks and swimming pool walls, contaminate factory equipment and medical implants, and sometimes coat the teeth as plaque. When such microbe gatherings stick to a hard surface, they’re called biofilms. They're al... Read More
I've been listening to the evolution of TWIM, week by week, and want to say that I am delighted by the direction it has gone. I listened to #11 yesterday and found the format especially informative and interesting. By format, I ... 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 is a magnified view of an Arabidopsis thaliana leaf eight days after being infected with the pathogen Hyaloperonospora arabidopsidis, which is closely related to crop pathogens that cause 'downy mildew' diseases. It is also more distantly related to the agent that caused the Irish potato fa... Read More
This episode: Bacteria and predacious fungi work together to trap nematodes!
thank you all for sharing your knowledge in such a comprehensible manner. Thank you also for your stand against bureaucratic censorship in the H5N1 research, and your win. I have two questions. Is H5N1 a highly specific test for a human ge... Read More
