Have there been any updates on this story? Hoax? spider? crystallization? life?
I found the original story in several places on the internet, but I haven't found any updates.

In situations such as this one rule of thumb would be "defining what is meant by life"---it may sound somewhat silly, but without a working definition the story coming from an everyday Newspaper requires "extraordinary evidence to back up such a claim."

One definition of Life (as specified by the NASA Exo-biology Program): "Life is a self-sustained chemical system capable of undergoing Darwinian evolution."

Not to go too far afield, what does this really mean? That there is an organism, probably a prokaryote, which can survive in the water? I don't find that particularly shocking, as Deinococcus radiodurans has an absolutely insane tolerance for radiation, and public water supply systems regularly find slime growing in their pipes.

When I read the thread title I thought there was news about an organism using uranium in its chemistry. My hopes were, alas, dashed.

They found fungus growing inside the Chernobyl reactor, so this being true would not terribly surprise me.
Life finds a way.
