NASA Finds New Life (This Afternoon)
While the official 2pm conference should have more answers, most of the internet has decided that NASA has discovered a completely new life form based on arsenic instead of the more traditional organic materials. We'll know more in a few hours.
Combined from two other posts I made:
If what's being reported is accurate, they've discovered a life form whose DNA was previously thought to be completely, unequivocally, no-exceptions impossible. Not just "we haven't found it", but impossible.
The point is that it means that life could exist in ways we haven't even conceived of yet. It's not the finding itself that's important, but rather the implications of having hard confirmed evidence that what we have long thought was wrong.

Perhaps its proteins use selenocysteines? Or it produces lots of de-arsenating enzymes, like bacteria that live in very hot temperatures (100 deg, say) produce more HSPs.
