Interesting article, Ron. Nothing new or out of the ordinary, though. They've known about extremophiles for years, now. All sorts of bacteria that can live and thrive in extremely hostile situations. Most can't live anywhere else. Our living conditions would kill most. Yet there are creatures which happily live with us that can tolerate these conditions also. I'd even wager that there's silicon based life forms here as well, let alone some of the other things mentioned by Dr Paul Davies.
Quite frankly, we don't even know what life actually really is. How do you define it....a dead organism is still that organism except it's bereft of life. It's more than the complex interaction of chemicals, electrical impulses and such. There's something which gives those chemicals and such organisation, gives them that spark. You can be as reductionist and literalist as you like, but you still have to face the question....what is it that makes and gives things life. So far, they've drawn a blank. They don't know....and won't know until they finally decide to start looking at some of the more "esoteric" sides of nature.
