Aquaporins are the pumps which regulate the water pressure inside cells . They keep out everything else, including sodium and chlorine ions.

Edit: neat stuff in your field Hermann. If they could figure out how to make that membrane, and many others like the biphosphate lipid layers, that would be amazing.

it doesnt matter what technology we invent, nature did it first, and a hundred times better. I read a book by Gerald Durrell where he describes a time when he met one of those old-tim pompous arses from the british empire who thought africa was there to be tamed and that man was better than beast, and he made a large bet that any three human inventions this guy named, he'd be able to show an example in the animal kingdom. Obviously he won the bet

one of the examples was the aqualung. Diving spider.

Definitely, nature has had quite a bit longer to perfect so many mechanisms. Theres so much more to learn.

Wow, that's awesome Hermann. NanoKids and ballet dancers. Really wacky, wild stuff.

yeah... all done because they could. and for publicity of course.

i like the self-assembled monolayers of them. I make self-assembled monolayers a lot.

At a conference really i saw something someone came up with:

the molecules attached to the surface had a ring structure on the other end, and had a rod through the ring, with one end hydrophobic and one end hydrophilic. The clever bit was that the rod was light sensitive so when light shone on the layer the rods all moved so the hydrophilic end poked upwards.

the dramatic result was that if you placed a droplet of water on the surface and shone a light NEXT to it, the droplet MOVED towards the light.

Oh Hermann, I read this article the other day and thought of you. Remember the British physicists who made that mathematical model which theoretically could cloak an object, well some researchers are building on that. Something like thousands of these tiny needles ten nanometers wide would project out from the cloak, and could bend the light around. The objects behind of course are visible as well. Cool shyte. Here it is from ScienceDaily

fascinating stuff. Imagine you could have invisible laser-quest games or something in rooms with only single-wavelength lights and everyone wearing cloaks. Or you could put tripping objects in your entry passages in your house so anyone who doesnt know the way trips over ... I expect there are less frivolous applications too.

Star trek has a lot to answer for.

Indeed. It would also give new fuel to the conspiracy fires. Big brother is in my house...:shock::confused2:

I'm not worried about what's in my place, more about what big brother does while cloaked, ewwww, dirrrrrty
