In 1969 David Baltimore proposed that poliovirus RNA replication is coupled with packaging, in that only those genomes actively replicating will be selectively encapsidated. From an evolutionary standpoint, it is an ingenious requirement to ensure that only virus genomes capable of replication ... 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
A drug candidate that has shown promise for neutralizing dangerous bacteria also prevents growth of the parasite that causes malaria, new research by a Yale University team headed by Nobel laureate Sidney Altman shows.
The compound created in the labs of Altman and co-senior author Choukri Be... 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...

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
The problem with antibiotics? We’re running out of them.
Over the last half-decade, our arsenal of powerful bacteria-killing medicines has slowly (though in biological time, rapidly) been depleted as nature, through evolution, outwits our efforts to develop chemical tools that can save us fro... Read More
Hello Vincent and Team TWIV,
I love Virology, and it is with much chagrin that I admit I have only recently started listening to TWIV. However I have tried to mend the error of my ways by: 1) proselytizing the benefits (keeping up-to-date with and... Read More
A new electron microscope that works without a lens may create the highest resolution images ever seen.
Transmission electron microscopy (TEM), which looks through an object to see atomic features within it, has been constrained for over 70 years by the relatively poor lenses that are used to... Read More
When I drafted my article for TakePart (Don’t Panic – Ebola Isn’t Heading For You), I used the term ‘ebolavirus’ throughout, but the editors changed every instance to ‘Ebola virus’. Understanding which term is correct is far more complicated than you might imagine. Read More
A year has passed since the last reported case of poliomyelitis in India, which occurred on 13 January 2011 in a two year old girl in Howrah, West Bengal. 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
The federal Food and Drug Administration is banning imports of all papayas grown in Mexico because of widespread and ongoing salmonella contamination, the agency announced Thursday.
More than 15 percent of fresh papayas entering the U.S. from Mexico were contaminated with the foodborne bacter... Read More
A new global study mapping human-animal diseases like tuberculosis (TB) and Rift Valley fever finds that an "unlucky" 13 zoonoses are responsible for 2.4 billion cases of human illness and 2.2 million deaths per year. The vast majority occur in low- and middle-income countries.
The report, wh... Read More
You’ve probably heard of "chickenpox parties," where parents get unvaccinated kids together (in the home of an infected child) in the hopes they'll catch the disease. They think making their kids suffer through the disease will help them develop stronger immunity than immunization would provide.... Read More
