New Theory on Water Strider Propulsion

capt.Hij writes "There is an interesting article at the Christian Science Monitor about how water skimmers are able to move the way they do. This new theory debunks the previously accepted theory and answers why smaller, younger water skimmers are also able to move the same way as their elders: 'As he looked into the question, he adds, he learned that the reigning explanation leaves an unsolved puzzle: If these tiny insects propel themselves in the way many researchers think they do, then baby water striders should go nowhere fast.'" There's also a BBC story with pictures.

    Everybody whose anybody knows waterstriders use anti-matter as propulsion.

    All I know about water skimmers/skippers is they're a bugger to hit with rocks, unless you get a really big, flat rock and even then you mostly just get yourself wet and still miss the skimmer.

    a) It's in Christian Science Monitor
    b) It's about skimming over the water.

    Chances are, Jesus features in the answer.

    They move because they put their faith in jesus and he spirits them along over the water on the wings of christ.

      Yeah, those three are the same.

      Do you mean that they don't believe cloning is possible, or that they don't believe evolution is moral?

      That would certainly be most people's first impression, but I find that the CSM is probably the *most* objective reporting I've ever seen to date. There doesn't seem to be any particular bias that I can see. I'm glad I found the CSM, and I really enjoy reading it, even though I'm agnostic. I highly recommend everyone take a look with an open mind.
      I second that. Compared with the mainstream press, it's utterly amazing how objective the Monitor has been throughout the whole water spider controversy.

    I think that since Science doesn't have all the answers its a false god and we must believe in the one god and creation.

    Walking on water isn't hard. Everyone can do it - just make sure that the temperature of the fluid-to-be-walked-on is subzero.

    Of course they get everywhere. They have such nifty propulsion systems after all.

    > Now all we need is to figure out how to make water have enough tension to hold a person. Hrmm...

    Simple. This happens naturally where I live. I simply have to wait until, say, mid-November. The surface tension remains high until some time in spring. It only works for water kept outside or in an unheated building.
