BBC News - 30,000-year-old giant virus 'comes back to life'


"It is a recipe for disaster. If you start having industrial explorations, people will start to move around the deep permafrost layers. Through mining and drilling, those old layers will be penetrated and this is where the danger is coming from."

Did they mention the giant virus only attacks single-cell organisms and is no threat to man?

Prolly didn't mention either than any real nasty virus froze up there (if one exists at all, probability non-zero) is most likely something we already have a nautural immunity to.

Zombies!

"the butterfly effect is the sensitive dependency on initial conditions in which a small change at one place in a deterministic nonlinear system can result in large differences in a later state. The name of the effect, coined by Edward Lorenz, is derived from the theoretical example of a hurricane's formation being contingent on whether or not a distant butterfly had flapped its wings several weeks earlier."
Prolly...

I'd be more worried about the sun spot activity and the work it is doing to the DNA code of the living as well as providing the right sort of energy to make newer, more interesting virus' in space...

Actually, the article did mention it attacked only amoebas. ;) But you have to read it.

Are yeast single cell organisms? Ninth grade biology left me decades ago.

But seriously - will the yeast die? Will there be no beer? No whisky?
