The gut microbiome has stolen the show when it comes to the recent explosion of research on the bacteria that thrive within us. But bacteria also live in a woman's breast tissue—and the mix of those microbes may have an equally important effect on health, according to a new study in Applied and ... Read More
Yoshinori Ohsumi, a Japanese cell biologist and ASM member, was awarded the Nobel Prize in Physiology or Medicine on Monday for his discoveries on how cells recycle their content, a process known as autophagy.
In a series of experiments in the early 1990s, Dr. Ohsumi used baker’s yeast to ide... Read More
In a very interesting development, a latest study has debunked the belief that it was safe to eat food fallen on the floor if picked up within “five seconds”.
Professor Donald W Schaffner, a food microbiologist at Rutgers University in New Jersey, said a two-year study he led concluded that no ... Read More
A specific strain of the fungus, Fusarium oxysporum, circulates in the water distribution systems of five French hospitals, in two widely separated cities. This microbe is potentially a life-threatening risk to immunocompromised patients. The research is published September 23, 2016 in Applied a... Read More
It is not unexpected that the contemplation of bacteria and archaea should focus so much on the nature and importance of their cell envelopes. Here, after all, is the interface between the cell's interior and the outside world. It is also what a host perceives early on when becoming infected.... Read More

Jeremy joins the TWiVeroids to tell the amazing story of how the function of the HIV-1 protein called Nef was discovered and found to promote infection by excluding the host protein SERINC from virus particles.

Bacillus anthracis had been studied by multiple countries as a potential biological weapon because of the stability of its spores and its ability to cause acute pulmonary disease. While offensive anthrax weapons development programs were halted in the United States and United Kingdom in the ... Read More
A new blog written by undergraduate students from the School of Genetics and Microbiology, Trinity College Dublin features Vincent Racaniello, PhD, host of This Week in Virology.
"Most students studying science at university will inevitably become familiar with the names and works of a wide r... Read More

Fungal contaminant, probable airborne, seen on BHI media containing 5% NaCl after 2 months at refrigerated temperatures. White hyphal "apron" with no spore formation can be seen at the edges with brown spore formation seen in the center. Read More
Four years to the day after filming 'Threading the NEIDL', Vincent and Alan return to the National Emerging Infectious Diseases Laboratories BSL4 facility at Boston University where they speak with science writer David Quammen during the Emerging Infectious Disea... Read More
The BBSRC and NERC-funded ShellEye project seeks to help shellfish farmers manage threats from harmful algal blooms and E. coli bacteria. The multi-partner ShellEye project brings together industry, government and scientists and aims to develop a satellite-based forecasting system to help fisher... Read More
How critical illness alters the microbiome, and the consequences of a sewage spill into an aquatic environment, from the TWiM team.
Dear Vincent, Elio, Michael, and Michelle,
I've just recently finished TWiM number 133 and wanted to comment about the use of the term "secondary metabolite" throughout the episode and often in the primary literature. Michael pointed out that a se... Read More
In the second of two shows recorded at the University of North Carolina in Chapel Hill, Vincent meets up with faculty members to talk about how they got into science, their research on RNA viruses, and what they would be doing if they were not scientists.

With California in its fifth year of severe drought and many western states experiencing another year of unusually dry conditions, plants are stressed.
Agricultural crops, grasses and garden plants alike can get sick and die when factors such as drought and excess sun force them to work harde... Read More
Evidence suggests that microbes existed on Earth as far back as 3.7 billion years ago, a billion years after the planet formed. Animal remains, however, don't appear in the fossil record until 600 million years ago during the Ediacaran period, though there are indirect signs that animal life may... Read More
A University of British Columbia mathematician may have discovered a key to understanding the constantly changing distribution of microbial species in the world's oceans—classify microorganisms by their biochemical function, rather than by their taxonomy.
Researchers have struggled to underst... Read More
