Great to see new discoveries in this day and age when you'd have thought most things had been found by now. I am sure there will be more to come, but it's slow going.

Probably my #1 ambition is to discover a new species of cactus!

Link is down, I'd love to have seen that. I've just started doing some hydroponics so I'm very interested in the subject.

So you squeeze cactus juice into dirty water and then filter it out leaving clean water behind; very neat.
