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
I would like to propose the book:
Explore Research at the University of Florida: Keith Schneider, an Associate Professor of Food Science and Human Nutrition at the University of Florida, explains what made him want to become a scientist originally, and what he enjoys about his career and research now. 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
Pared down genomes are the norm in symbiotic microbes, but how do non-symbionts get away with cutting out functions it would appear that they need? The authors of an Opinion piece in mBio this week explain their ideas about the matter. They say microbes that shed necessary functions may well be ... Read More
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
Dear TWiM Team
A fascinating article from New Scientist this week.
Standard medical teaching is that the foetus is sterile and that the microbiome only begins to develop post natal.
New research from Spain indicates that the microbiome s... Read More
A person’s mere presence in a room can add 37 million bacteria to the air every hour, a new study finds.
The bacterial material is largely left behind by previous occupants and stirred up from the floor when someone enters.
“We live in this microbial soup, and a big ingredient is our own m... 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
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
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
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
Non-acid-fast rods. (approx. 1000 X). Taken from the Wistreich Collection, appearing exclusively on MicrobeWorld. 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
