Understanding the evolution of life-threatening viruses like influenza, Ebola and dengue fever, could help us to minimize their impact. New research points the way to a fossil record of viruses that have insinuated themselves into the genomes of insects and other animals, providing clues about t... Read More
It's a cliché, I know - but a generation of scientists is passing whose like we truly may never see again. Frank Fenner has died in Australia, at the respectable age of 95, days after meeting his first great-grandchild.
And what a passing. Fenner comes from the era when so much was undiscover... Read More
On episode #108 of the podcast This Week in Virology, Vincent, Alan, Rich, and Saul review the evolution of HIV-1 specific recombinases, and down-regulation of a host microRNA by a viral noncoding R... Read More
Hello everyone, dear doctors Racaniello, Despommier, Alan Dove and Rich Condit,
I've been a devoted listener since April 2009. Like many others listeners then I quickly caught up with all previous episodes (I'll never forget that memorable one devoted ... Read More
Viruses possess an ability to mutate into strains that can render vaccines useless and become deadlier than their predecessor. But for a team of Texan scientists, this biological danger became a forensic asset that helped prosecutors convict two men accused of infecting close to a dozen women wi... Read More
If you’re unlucky enough to experience a case of gastroenteritis, you might endure several days of diarrhea and then think your woes are over.
Not so fast.
According to a study published online Friday in the British Medical Journal, a bout of acute gastroenteritis can increase one’s risk o... Read More
At this point, after finding microorganisms that don’t mind extreme temperatures, pressure, aridity and other hardships, we shouldn’t be surprised that bacteria’s dominion over the Earth extends to just about anywhere we look. A new expedition to the Earth’s crust has reached unprecedented depth... Read More
An inexpensive new filtering technology can kill up to 98 percent of disease-causing bacteria in water in just seconds without clogging.
American Chemical Society's (ACS) award-winning podcast series, "Global Challenges/Chemistry Solutions", latest episode focused on development and successfu... Read More
Researcher Jean-Paul Meijnen has 'trained' bacteria to convert all the main sugars in vegetable, fruit and garden waste efficiently into high-quality environmentally friendly products such as bioplastics. He will be defending his doctoral thesis on this topic, which was carried out in the contex... Read More
Scientists are zeroing in on a promising vaccine to treat hepatitis C, an international symposium was told Friday in Montreal.
Three preliminary clinical trials in England are showing that a so-called therapeutic vaccine can boost the immune response in those infected with the hepatitis C vir... Read More
Researchers at Rush University Medical Center in Chicago have discovered a protein produced by HIV that keeps infected cells from signaling the immune system that they are harboring the virus and should be killed. These data, which suggest a new target for HIV drugs, were published online Octobe... Read More

Hi, Vincent and Dick,
Love your podcast, and did not drink from the streams in Switzerland, because of the cows at all altitudes, even though your Giardia-cast only came up upon my return. Read More
Listeria can pose special challenges for artisan cheesemakers. Many make their cheese right on the farm, where the bad bacteria are right outside the cheese room door. And small producers often lack the safety training and resources available at bigger companies.
For example, Sharon McCool g... Read More
The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and "fixing" or storing carbon.
The research, just published in the journal PLoS One, showed that ... Read More
People who contract gastroenteritis by drinking E-coli infested water are at a greater risk of developing high blood pressure, kidney problems and heart disease in later life, says a study.
The findings underline the importance of ensuring safe food and water supply and the need for regular m... Read More
Contrary to long-held beliefs, plants and animals have developed remarkably similar mechanisms for detecting microbial invasions. This holds promise for the future treatment of infectious diseases in humans.
It may have been 1 billion years since plants and animals branched apart on the evolu... Read More
Government experts are urging those eligible for the vaccine to have it otherwise they will remain vulnerable to flu this winter.
Uptake rates so far this season have shown that fewer people are having the jab than last year.
At the end of October, 48 per cent of over 65s had so far accept... Read More
