Yahoo! News - Scientists Build Virus from Scratch WASHINGTON (Reuters) - Using only a genetic map as a guide, U.S. researchers said on Thursday they had built a polio ( news - web sites) virus from scratch and used it to infect and paralyze lab mice.

It is the closest anyone has yet come to creating life in a test tube -- although scientists deny a virus, which is not a living cell but which can replicate itself, is alive in the same way a bacterium, a plant, or a human being is.
Nonetheless, it has genetic material like all other life.
