As the world’s athletes limber up for the forthcoming Olympic games in London, infectious-disease experts are preparing for their own trials. Their competition is with the diseases that millions of athletes, officials, media and spectators bring with them as they converge from across the globe o... Read More

1) The Blob
Like many of the X-men, the Blob has gone through several incarnations of character but the one main continuous feature is that he’s big. That’s pretty much it. The size gives him supernatural s... Read More
Hello to the TWiV crew,
Here are a couple of picks I thought would be good for provoking thought and generating discussion...
While working on a project, I came across some papers attempting to define what "critical thinking" means. I app... Read More
In the search for new life, scientists have studied the depths of the ocean and the lips of steaming volcanoes. They've looked on Mars and the moons of Jupiter, and even planets beyond this solar system.
Dr. David Relman went searching inside his own mouth. On a routine dental visit in 1998, ... Read More
Better resistance to parasites and a less fussy diet are allowing aggressive signal crayfish from the US to threaten white-clawed crayfish native to Yorkshire.
The Yorkshire crayfish suffers from two parasites: plague, which is carried by the American invader, and porcelain disease that makes... Read More
A bacterium recently discovered near Death Valley has some very unusual properties according to a report published in the December 23 issue of Science magazine. While some ‘bugs’ are like migratory birds, making tiny magnets that they use to guide their navigation, this is the first bacterium to... Read More
Top US scientists on Wednesday defended their bid to stop details of a mutant bird flu virus from being published and called for global cooperation to ward off an uncontrollable pandemic.
Meanwhile, scientists involved in the experiments said they are cooperating with government officials and... Read More
'Second part of my thinly veiled excuse to research X-men and call it work. The first post can be found here. This is only meant to be a two-parter but I’ll see how I feel on Monday, and whether I can find any more X-men that are as amazing as bacteria.'

Are you, Alan Dove and Prof. Racaniello, saying you think Mikovits and/or others on the Lombardi paper lied about the results or blinding? I think circumspection is a natural human reaction to the allegations of theft that have been made against Dr. Mik... Read More
By altering how plants turn sunlight into chemical energy, scientists hope to produce biofuels that make economic sense.
For years researchers have been trying to figure out the best ways of making plants produce biofuels. But there is a fundamental problem: photosynthesis, the process by wh... Read More
Norton Zinder made two important discoveries in the field of virology. While a Ph.D. student with Joshua Lederberg at the University of Wisconsin-Madison he found that viruses of bacteria (bacteriophages) could move genes from one host to another, a process called transduction. Later in his own ... Read More
Hello Professor Vincent,
First of all, thank you for your wonderful podcasts! I'm a CFS sufferer and also a student Applied Science so I'm interested in many of the topics discussed for those two reasons and always learning new things.

We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often comp...

A North Carolina State University study shows that, for the first time since testing began several years ago, feral pigs in North Carolina have tested positive for Brucella suis, an important and harmful bacteria that can be transmitted to people.
The bacteria are transmitted to humans by uns... Read More
The epidemiology episode with Michael Walsh was great. I loved the philosophical detour into counterfactual statements, time travel, and the meaning of causation. TWiV may indeed be viral, but from listening to it I fee... Read More
In a French meadow, a creature that specialises in corrupting the bodies of other animals is getting a taste of its own medicine.
Leptopilina boulardi is a wasp that lays its eggs in fly maggots. When the wasp grub hatches, it devours its host form the inside out, eventually bursting out of its... Read More
An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.
The new research assessed the association between bacterial... Read More
Manmade climate change is the main driver behind the unexpected emergence of a group of bacteria in northern Europe which can cause gastroenteritis, new research by a group of international experts shows.
The paper, published in the journal Nature Climate Change on Sunday, provided some of th... Read More
Advances in the 1950s and 1960s, including unprecedented cooperation between Soviet and U.S. scientists, allowed polio to be eradicated throughout the Americas by 1994 and all of Europe in 1998. Eliminating the crippling scourge has been more difficult, however, in some parts of Africa and Asia.... Read More
It may not be the latest style in bovine bling, but researchers at Princeton University say a golden tattoo attached to a cow’s tooth could one day tell you something about your health.
The remote sensing device has the ability to detect a single bacterium, and to demonstrate, scientists at P... Read More
