Could bacteria be responsible for colon cancer? In papers published in the journal Genome Research, two research teams, working independently, describe a group of bacteria that are linked to higher rates of the disease.
Called Fusobacterium, this type of bacterium is very rarely found among ... Read More
It may be possible to eliminate the deadly dengue fever by infecting mosquitoes with a bacterium called Wolbachia that prevents the mosquitoes from transmitting the dengue virus to humans. A new mathematical model, developed by Nick Barton (Institute of Science and Technology, Austria) and Mich... Read More
The NIH Human Microbiome Project has been a 5-year endeavor to produce community resources to support the field of human microbiome research. Although the HMP has already produced hundreds of peer-reviewed publications, in the past week 2 major HMP Consortium papers as well as 20+ companion pap... Read More

Fernan Federici, a researcher in the Haseloff Lab at Cambridge University and one of the Synthetic Aesthetics residents, studies how cells grow and develop into complex shapes and structures. Using confocal microscopy, he tracks the growth of plant cells and tissues, creating models of how cell ... Read More
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
Red duct tape can save healthcare workers time and hospitals money by defining a "red box" just inside patient rooms in which healthcare workers can communicate with patients who are isolated with infections without stopping to don a gown and gloves. The approach extends the "safe zone" and redu... 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
As usual I loved TWiM #37. Jo Handlesman adds a lot imho.
I think Michael Schmidt meant "dump data" instead "data dump." Apologizes to Alan Dove.

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
Researchers have constructed a new synthetic bacterium that detects Pseudomonas aeruginosa, a common microbe and a leading cause of hospital-acquired infections, and explodes, releasing antimicrobials that kill the invaders. The results, published today (August 16) in Molecular Systems Biology, ... Read More
Hello to Vince and all you other wise humanitarian folks bringing us TWIM and TWIV! I am a 47 year old indiviual diagnosed with GAD and OCD. Germaphobia used to be my most prevalent and crippling symptom of these disorders until my family doctor found... Read More
Extended spectrum beta-lactamases (ESBL's) are enzymes that enable bacteria to resist multiple antibiotics. In the past few years ESBL-producing enteric bacteria (such as E. coli) have become an increasingly common cause of community acquired infections worldwide. The source of these organisms i...

The human navel should be designated as a bacterial nature reserve, it seems. The first round of DNA results from the Belly Button Biodiversity project are in, and the 95 samples that have so far been analysed have turned up a whopping total of more than 1400 bacterial strains. In 662 cases, the... Read More
