They can cause a variety of symptoms, from cold-like symptoms such as runny nose or fever to more se... Read More
To the amazement of researchers in immunology and genetics, a previously unsuspected mechanism is activated in the presence of pathogens after only a few hours. "In the hours following an attack by bacteria, we observed the activation of thousand of genes in the cells of the innate immune system... Read More
Having confirmed the first cases of infection in Suriname then in French Guiana, the Institut Pasteur in French Guiana has sequenced the complete genome of the Zika virus, which is responsible for an unprecedented epidemic currently sweeping through the tropical regions of the Americas.

We are, supposedly, outnumbered in our own bodies. We play host to an extraordinary menagerie of bacteria and other microbes—the microbiome—and it’s frequently said that these teeming cells outnumber our own by ten to one. This 10:1 ratio crops up everywhere. It appears in scientific papers, blo... Read More

In episode #3 of the new science show This Week in Evolution, Nels and Vincent examine another important driver of evolution: recombination. The results of two papers in which the process is studied in finches and in yeast lead to the unexpected conclusion that recombination evolves more slowly ... Read More
As we’ve seen in numerous cases in 2015, food contamination is a real issue for a number of different food types. Vegetable, meat, packaged, fresh – even pet food – we’ve seen too many examples of how bacteria can outsmart our best food safety practices. The Canadian government estimates 1 of ev... Read More
When the Ebola virus outbreak erupted in West Africa in 2014, children infected with the virus -- particularly those under age 5 -- faced overwhelming challenges.
