Dear Dr. Racaniello
I was watching the conference in Dublin and I wanted to thank you for sharing my e-mail with the people in the panel, since I saw how nice it was for me to reach the specialists with that ease through TWIV.<... Read More
If you know anything about snakes you might be familiar with snake inclusion body disease, or IBD. This transmissible and fatal disease affects snakes of a variety of species but has been best studied in boas. The name comes from the presence of large masses (inclusions) in the cytoplasm of cell... Read More
A synthetic mixture of intestinal bacteria could one day replace stool transplants as a treatment for Clostridium difficile (C. difficile). C . difficile is a toxin-producing bacteria that can overpopulate the colon when antibiotics eradicate other, naturally protective bacteria living there.

Just a quick note to say how much I enjoy TWiM, and in particular, how much I enjoyed episode 32 featuring Rosie Redfield. I don't know how you find time to do this, but I'm gl... Read More
Enceladus, Saturn’s 318-mile-wide moon that’s become famous for its ice-spraying southern jets, is on astronomers’ short list of places in our own solar system where extraterrestrial life could be hiding — and NASA’s Cassini spacecraft is in just the right place to try and sniff it out.
On ... Read More
Volcanoes bring death and destruction, but out of the ashes life soon finds fertile ground. A unique experiment is sifting through floating debris from an ongoing volcanic event to see how microbes move in. The results may help in assessing a recent hypothesis that the first life forms may have ... Read More
New research shows that killer whales are inhaling bacteria, fungi and viruses once believed to be found only on land. Some of the pathogens are highly virulent. And some are even antibiotic-resistant.
The scientists followed the killer whales by boat, trying to catch the precise moment the a... Read More
A bacteria that is known to be associated with more than 80% of gastric and doudenal ulcers, may be associated with infant colic. The bacteria, Helicobacter Pylori (H.pylori), is found in the lining of the of the stomach wall.

Two controversial papers on bird flu will be published by scientific journals this year after the go-ahead was given by a U.S biosecurity panel.
The National Science Advisory Board for Biosecurity (NSABB) took a stand over the papers last year out of concerns that details of the studies - whi... Read More
The fields of microbial symbiosis and speciation have achieved astonishing advances during the past two decades, yet symbiosis and speciation are not commonly discussed together and can seem to be odd partners in their capacity to operate synergistically in nature. Indeed, microbial symbiosis is... Read More

One of two papers on avian influenza H5N1 virus that caused such a furor in the past six months was published today in the journal Nature. I have read it, and I can assure you that the results do not enable the construction of a deadly biological weapon. Instead, they illuminate important requir... Read More
"Take a listen to four very savvy and plain-talking biologists chatting on their business at an inside-the-academy site called This Week in Microbiology, and more specifically at episode TWiM 32. There host and Columbia U. faculty member Vincent Racaniello and two colleagues talk of arsenic and ... Read More
As a pediatrician, I spend a lot of time looking for bacteria that might be making my patients sick. Some well-known illnesses that are caused by bacteria include strep throat, ear infections, Lyme disease and conjunctivitis (pinkeye). Bacteria are also responsible for acne, cavities and body od...

Escherichia coli is no stranger to the human body. In around 20% of us, E. coli is the predominant species in our gastrointestinal tract, where it lives as a commensal. But when E. coli gets out of hand it can cause anything from gastroenteritis to sepsis to urinary tract infections. It's those ... Read More
The Obama administration has announced a new policy to handle the risks posed by legitimate biological research that could, in the wrong hands, threaten the public.
The move comes in response to a huge debate over recent experiments on bird flu virus that got funding from the National Institu... Read More
Harvard Medical School researchers have engineered a photosynthetic cyanobacterium to boost sugar production, as a first step towards potential commercial production of biofuels and other biotechnologically and industrially useful carbon compounds. As feedstock producers, cyanobacteria have adva... Read More
In a new study, scientists have determined a possible link between exposure to a common component of urban air pollution and a change in the function of important immune cells that protect against the bacteria that cause tuberculosis.
In their finding, a team of researchers, led by Dr. Steph... Read More
Researchers use stealthy nanoscale particles to infiltrate vaginal mucus and keep herpes at bay in mice.
Tears and a runny nose can be unpleasant on a windy day, but these mucosal secretions play a vital role in protecting the body from viruses and other malicious microbes. Unfortunately, muc... Read More
Other than basic stuff like the Earth rotating around the sun and E=MC2, how much do you know about the universe? Most people would say: not very much. But if you’re a theoretical physicist, you probably know quite a bit more--but still not that much; most of the mysteries of the universe still ... Read More
