KRÖHÖM!
I can tell you what the discovery is, since it was leaked:
The discovery is about a new form of life found on Earth, in the Mono Lake in Yosemite park, California.
These lifeforms are constructed completely differently than the modern life forms that we equate life to be, as they do not have the same DNA/RNA characteristics that are lifeforms have - the are based on arsenic.
Our current lifeforms, and those we have been seeking for outside in space, contain phosphorus, and in these lifeforms there is no place for phosphorus. They are built around arsenic.
While this is not they E.T life update we all hoped for, it's a huge step in realizing that there many more possibilities for life in space very different than ours, we who live of oxygen.
