Traditionally, colonization of a host has been described in terms of a microbial community that does not affect the host, but recent research (such as the Human Microbiome Project) suggests that colonizing microbes are having an effect not only on the host, but on each other. Participants discu... Read More
The Society for General Microbiology (UK) publication Microbiology Today has a two page feature by Paul Duprex, Ph.D., Boston University, on Vincent Racaniello, Ph.D., Columbia University, and his popular podcast This Week in Virology. The article discusses Racaniello's use of new media to sprea... 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
I would like to propose the book:
I guess it doesn't sting, which is a plus - clearly we need no more stinging/biting/blood-sucking creatures on this earth - but my real wonder is what's next, and why rat heart muscle? 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

If we can visualize a protein's shape, we can learn much more about how it functions and how we might block its activity. This was the guiding principle behind an NIH initiative launched 25 years ago to spur the discovery of HIV-related protein structures. Structures produced through the program... 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
Dictyostelium discoideum is a soil-living amoeba. A group of 100,000 form a mound as big as a grain of sand.
The hereditary information is carried on six chromosomes with sizes ranging from 4 to 7 Mb resulting in a total of about 34 Mb of DNA, a multicopy 90 kb extrachromosomal element that h... 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
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
