How Viruses Evolve, and in Some Cases, Become Deadly

Resource: http://www.sciencedaily.com/releases/2012/01/120126224526.htm Summary: Researchers have recently been looking at how viruses evolve and mutate into something worse and can become deadly. They first looked at a sickness called Lambda, it's not deathly to humans but they did notice that it mutated into something else and started to atack cells. They didnt really believe it at first so they kept watching it and they said that it happened every single time. The researchers also noticed that the bird flu had gotten very deathly for humans because it mutated into something that was very deathly. Hopefully they are going to keep an eye on these viruses and make sure that non of them get worse. Critique: This article was very interesting and really got me thinking which makes a good article. Impact: This article could have a huge impact if things get worse and sickness' keep mutating, so hopefully if that does happen doctors can find cures to make sure things don't get bad.
