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
Mathematics and Biology have a long history together. It goes back to early studies on epidemiology (such as John Snow‘s on cholera and the Broad Street pump), and includes Ross’s quantitative studies that show how malaria can be controlled by careful analysis of data. And, of course, there are ... 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
I would like to propose the book:
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
A group of seventeen virologists is asking a U.S. government biosecurity advisory board to reconsider its controversial recommendation that two research teams omit key details from papers in press at Science and Nature. They note that the H5N1 fatality rate quoted widely is incorrect, and that ... Read More
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
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
This episode: Bacteria and predacious fungi work together to trap nematodes!
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
Dear Vincent Racaniello and Dickson Despommier
I am an avid listener of TWIP since its start, have been following TWIV for at least two years and, surprise, also follow TWIM.
My field is Computer Science, but I crave for... 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
