A former microbiology student sent me this link to a promotional spot from a football game. There is a microbiological blooper involved, suggesting that we all need to work harder to promote Microbial Literacy...even on the football field! Read More
Planet Earth is surrounded by a bubble of live bacteria scientists have found.
According to a report by Popular Science the colonies of bacteria live at about 33,000 feet - roughly the cruising height of a passenger jet.
But while it might sound strange, it appears the phenomenon is a cruc... Read More
Hepatitis A virus (HAV) is classified as a non-enveloped Picornavirus. That may have to change, or at least be more specific.
Via electron microscopy, this team found a certain percentage of these viruses were enveloped in exosome-sized particles. Up to 4 virions were found inside these membr... Read More
A growing body of evidence suggests that all the antibacterial-wiping, germ-killing cleanliness of the developed world may actually be making us more prone to getting sick — and that a little more dirt might help us stay healthier in the long run.
The idea, known as the hygiene hypothesis, wa... Read More
Scientists trying to put HIV-prevention methods in the hands of women have been disappointed so far in their efforts with vaginal microbicides. In the lab, in vitro testing of microbicides like nonoxynol-9, and cellulose sulfate have produced promising results, but when subjected to clinical tri... Read More
As public health officials sound the alarm about the global spread of drug-resistant bacteria, researchers are working to develop more effective antibiotics to counter this dangerous trend. Now, results from a team including a Princeton University scientist offer a possible solution that uses th... Read More
A federal advisory committee yesterday recommended increased biosafety precautions for research involving H5N1 avian influenza viruses that can spread among mammals, a step that stems from the ongoing controversy over studies involving lab-modified H5N1 strains that show increased transmissibili...

Using new software developed at HHMI’s Janelia Farm Research Campus, a computer can be trained to recognize characteristic animal behaviors like an experienced biologist. Rather than scrutinizing hours of video to catalog how often fruit flies chase one another, for example, scientists can quick... Read More
By varying laser and electric fields, scientists can use tiny centrifuge-like whirlpools to separate particles and microbes.
The technology could bring innovative sensors and analytical devices for lab-on-a-chip applications, or miniature instruments that perform measurements normally requiri... Read More
This is a joint project with water color artist Sarah Roberts to study the interaction of bacteria with traditional water colors. Many different types of bacteria have been assessed but only two so far, can be said to paint. When the white pigmented bacterium Proteus mirabilis, and the red Serra... Read More
The virus used in the vaccine that helped eradicate smallpox is now working its magic on liver cancer. A genetically engineered version of the vaccinia virus has trebled the average survival time of people with a severe form of liver cancer, with only mild, flu-like side effects.

Hawaii has several official state symbols, including a flower, a song and a flag, but some say that's not enough.
"Missing from this group of symbols is an official state microbe," Rep. James Tokioka wrote in a bill proposing to add a microbe to the list.
Hawaii House members considered th... Read More
Poliovirus has made the cover of Time magazine. The Time cover image for the 14 January 2013 issue is a model of poliovirus bound to a soluble form of its cellular receptor, CD155. I was part of the team that solved the structure of this complex in 2000, together with the laboratories of Jim Hog... Read More
A new type of microbe has been found at a lake buried under Antarctica's thick ice, according to news reports. The find may unveil clues of the surrounding environment in the lake, according to scientists.
The bacteria, said to be only 86 percent similar to other types known to exist on Earth... Read More
A tiny molecular machine used by bacteria to kill attacking viruses could change the way that scientists edit the DNA of plants, animals and fungi, revolutionizing genetic engineering. The protein, called Cas9, is quite simply a way to more accurately cut a piece of DNA.
“This could significa... Read More
The influenza virus genome consists of eight negative sense RNA segments. The segmentation allows efficient genetic exchange among influenza viruses co-infecting the same cell. But this strategy has its costs, namely, that each virion has to ensure that all eight segments are specifically pack... Read More
Harvard University is home to some of the world’s finest virologists. But apparently they do not communicate with the writers at Harvard Magazine, where a botched story on the avian H5N1 influenza virus has just been published. Read More
The search for a cure for deadly infectious disease like Tuberculosis has led a researcher for the US deep underwater.
Brian Murphy, assistant professor of medicinal chemistry and pharmacognosy at the University of Illinois at Chicago, is collecting actinomycete bacteria from water throughout... Read More
