In fact, infected mice were mildly attracted to the odor of cats. This side effect likely evolved because the parasite…

  A recent article posted in the BBC News provided a good explanation of why scientists commonly study these organisms as models for human diseases and conditions. Model organisms are chosen because their physiology is similar to other animals, including humans, in addition to other reasons: Visit the BBC News to see why researchers most often use flies, fish, mice and worms…
