Merry Youle from the Small Things Considered blog ponders the potential size a virus can be:
"With such fascinating stories being told by Mimivirus and the other giants, people are now looking for them in more environments. Modified techniques are called for, as those used previously to spot ... Read More
A team of scientists, led by Mauro Delogu, virologist from the Veterinary Faculty of the Bologna University and researchers from the Istituto Superiore di Sanità, Istituto Zooprofilattico Sperimentale della Lombardia e dell'Emilia and St. Jude Children's Research Hospital (Memphis, Tennessee) ha...

Human history marches to the beat of what? A big brass band? A choir singing hymns? The lub-dub of the human heart? Sonia Shah’s tour-de-force history of malaria will convince you that the real soundtrack to our collective fate is none of these: it is the syncopated whine-slap, whine-slap of ma... Read More
This episode: Using cold-loving genes to make vaccines!
Biologists have demonstrated a connection between multiple sclerosis (MS)—an autoimmune disorder that affects the brain and spinal cord—and gut bacteria.
Details of the findings appear in the Proceedings of the National Academy of Sciences.
Multiple sclerosis results from the progressive d... Read More

When cells are attacked by bacteria they use all means at their disposal to defend themselves. But cellular defence systems can damage the cells themselves and so need to be kept tightly in check. Recent results help us to understand how this is done and give pointers to new ways of combating di... Read More
Public health officials have been working for months to understand whether the XMRV virus poses a risk to the nation’s blood supply. The concern was sparked by a paper published last year in Science that detected the virus in the blood of 67% of chronic fatigue syndrome patients, compared to ju... Read More
Like a burglar with a universal lock pick, many deadly pathogens use the same protein to gain access to the cells of a potential host, researchers have discovered. The new findings could have implications for blocking infections by agents ranging from wheat rust to malaria.
Pathogenic fungi, ... Read More
In a laboratory where almost all the test tubes look green, the tools of modern biotechnology are being applied to lowly pond scum.
Foreign genes are being spliced into algae and native genes are being tweaked.
Different strains of algae are pitted against one another in survival-of-the-f... Read More
As if rows of serrated teeth and an uncanny ability to smell blood weren't deadly enough, sharks now have a new way to harm unsuspecting swimmers: drug-resistance bacteria.
According to recent research in the Journal of Zoo and Wildlife Medicine, sharks and redfish from shores off of Massachu... Read More
Over the last year, there has been a question on the minds of thousands of people that continues to be for the most part unanswered: Why do disinfectants and hand sanitizers kill only 99.9% of germs and not the full 100%? Or, more succinctly, why is there always 0.1% survival? Read More
Scientists have successfully tracked the progression of influenza virus infections within the lungs of mice. Influenza A virus, the type of flu that causes most seasonal and pandemic outbreaks, has been studied extensively in animal models and tissue cultures. However, the way it moves through t...

How a retrovirus, like HIV, reproduces and assembles new viruses is different than previously thought, according to researchers.
The team studied a chicken virus called Rous sarcoma virus that causes cancer in chickens and is similar to HIV.
“The question is, how do retroviruses build new ... Read More
The best defense against a deadly superbug might be a virtual offense.
Duke University researchers are expanding upon a computer program they invented last year to predict how a rapidly mutating, infectious bacterium will evolve to evade the drugs used against it. Getting a glimpse into what ... Read More
A woman planning a Florida vacation in Key West called the health department there last week to ask if it were true that the city was being evacuated because of an epidemic of dengue fever.
“No!” Chris Tittel, a spokesman for the Monroe County Health Department, says he told her. “No, no, no... Read More
