Hey kids,
In a controversial study, researchers have resurrected a retrovirus that infected our ancestors millions of years ago and now sits frozen in the human genome...

The researchers showed that the newly crated virus could infect a variety of human cell lines and replicate. But its infectivity was extremely low, perhaps because human cells have evolved resistance against such viral invaders...

"I think it's pretty exciting," says John Coffin, who studies retroviruses at Tufts University in Boston.

Haven't TV and movies yet taught us that everything "scientists" do will somehow kill us all? The only way scientists can help us is if they are just one of a handful of castaways on an uncharted desert isle. Even then, their benefit is limited, but then so is their destructive power.

I'm not as worried as I might otherwise be though- I mean "ancestors millions of years ago..." and "evolved resistance-" These guys can't be that good of scientists if they're working from premises like that.

Am I right, or am I right?
