To the best of our knowledge zombies aren't real, but if there ever is a zombie outbreak in the future we now have an epidemiological model we can use for predictive analysis. Created by several Canadian mathematicians at the University of Ottawa, "When Zombies Attack! Mathematical Modeling of ... Read More
Brown University researchers have discovered that Candida albicans, a human fungal pathogen that causes thrush and other diseases, pursues same-sex mating in addition to conventional opposite-sex mating.
Scientists have observed this same-sex mode of reproduction in other fungi, but this is t... Read More
As summer hits its stride, many Americans are taking a moment to step into their backyards and smell the roses. And lilies. And, uh, raccoon feces?
That's the case for many Americans living near woods or marshes. And backyard "raccoon latrines" -- spots created by the animal as a kind of shar... Read More

Albert Osterhaus, head of virology at the Erasmus Medical Center, designed "The Great Flu" game with colleagues. In the game, as the head of the fictitious "World Pandemic Control," players pick a flu strain, and then monitor that strain's spread around the world.
I am familiar w/ this particular disease from working @ an animal hospital, where our veterinarians fielded numerous questions about it. While the disease was never detected there, it did cause a fair amount of worry amongst local dog owners. Interesting that it is rearing it's head again now,... Read More
