The lethality of avian influenza H5N1 infections in humans has been a matter of extensive debate. The >50% case fatality rate established by WHO is high, but the lethality of the virus might be lower if there are many infections accompanied by mild or no disease. One way to answer this question ... Read More
GEMINA is a web-based system to identify infectious pathogens and their representative genomic sequences through selection of associated epidemiology metadata. Gemina supports the development of DNA signature-based assays for the detection of pathogens or sets of pathogen through the Insignia Si... Read More

Developing tricks and tools to keep their enzymes in order is one way thermophiles survive. They also use techniques to keep their DNA from falling apart under intense heat. Like proteins, the parts of the long, spiral ladder-shaped DNA molecule start to unravel and break apart under high hea... Read More
