What happens to us after we die? A decomposing corpse becomes its own mini-ecosystem, hosting insects, scavengers and multitudes of microbes. Microbes from the environment, the corpse, as well as the insects and scavengers are blended together and work to recycle tissues back to t... Read More
Humans have used Saccharomyces cerevisiae yeast in baking, brewing and winemaking for millennia. New research from the University of Idaho and the University of Colorado Boulder reveals another way that yeast species can help our species: by demonstrating how viruses interact with their hosts, a...

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
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.
Host: Read More
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
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
This episode: Killing pathogens by attaching magnetotactic bacteria to them and then raising the heat with magnetic fields!

There is a growing popular and policy interest in the microbiome, and the possibilities of more nuanced or ‘probiotic’ ways of living with germs. To date however there has been limited public engagement with the science and technology of metagenomics. The project engages with the growing scienti... 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
Colostrum is a thick, sticky, yellowish mammary secretion that all mammals provide to their newborns during the first 24-48 hours after delivery.
It has been reported that constituents from BC are 100-fold to 1,000-fold more potent than human colostrum. This means that even human infants can ... 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
The TWiM team discusses the importance of neutrophils in microbial infections, and evidence that ancient bacteria had two cell walls.
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
For the first time a virus that targets bacteria has been found to have genes lifted from non-bacterial cells – those of the black widow spider. Read More
The bacteria Pseudomonas aeruginosa can thrive in environments as different as the moist, warm tissue in our lungs, and the dry, nutrient-deprived surface of an office wall. Such adaptability makes it problematic in healthcare – where it causes infections in cases of cystic fibrosis, cancer, HIV... Read More
Two vaccines against Zika virus developed at the University of Pittsburgh School of Medicine have successfully conveyed immunity from female mice to pups conceived weeks after the mother's vaccination.
When challenged with Zika virus within a week of their birth, both vaccines protected the p... Read More
Washington, DC – October 4, 2016 – A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study, reported online this week in the journal mB... Read More
Disease detectives are on the lookout for obscure viruses that can be spread among people by traveling insects, and quickly become a widespread problem. Scientific papers are filled with illnesses to watch. Four particular viruses now stand out to virologists and epidemiologists, although it is ... Read More
The world's oceans teem with scientific mystery, unknowns that could prove to be tools that will one day protect the planet from global warming.
An international research team now reports they've tripled the known types of viruses living in waters around the globe and have a better idea what ... Read More
