Enterococci had been generally regarded as benign commensals, a part of our healthy intestinal microbiota. They were even invited in, being used as probiotics. But then, in the late 1970s, the first multiple drug-resistant strains appeared, and vancomycin-resistant strains followed in 1981. In r... 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
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
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
Hi Dr Racaniello,
I am a long time listener of TWIV and really enjoy the informal scientific discussions. I listen to TWIV while working in the lab and am trying to catch up on TWIM and TWIP episodes too.
I have been dill... 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
Virulent drug-resistant "superbugs" are back in the news. We have a lot to learn from these small but smart creatures. To the dismay of many in the pubic health field, the FDA just dropped plans to enforce a 1977(!) decision to limit the use of antibiotics in animal feed, which facilitates the e... 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.'

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
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
Monkeys and apes are considered edible game in many parts of Africa. As people from these regions have emigrated to other parts of the world, some have retained their love of this and other types of bushmeat. A new study now finds that meat from nonhuman primates — from chimps to monkeys — can h... Read More
Dear Twim team
An interesting paper on artificial selection of yeast giving rise to evolved clusters. The clusters evolved to be larger, produce multicellular progeny, and even s... Read More
Ira Flatow of Science Friday will host a panel discussion on the issues surrounding a federal advisory board that has urged scientific journals not to publish the research from two labs that have developed an airborne bird flu virus (H5N1). Virologist Vincent Racaniello and Biosecurity expert D.... 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
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...

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
