Help friend repair puncture on a new Scott bike and it didnt have quick release. Instead it had nuts with long levers that you just tighten. Is this the latest thing? Are they called thru-axles or it that something else?

    Some older lower-priced bikes used to have large 'wing nuts' instead of quick release clamp-type skewers to hold the wheel into the drop-outs. Loosening the nuts allowed the wheel to easily be removed without the need for a wrench.
    Could be that someone just removed the usual skewers and replaced with what's there now.
    Is the axle hollow so that a skewer rod would go thru it?

    On the Scott, does the wheel just 'fall out' of the frame/fork when the nuts are loosened, or do the nuts have to be completely removed?

    Sounds like through axles to me. They're used in mountain bikes in various forms and sizes because they're stiffer & more secure than QR. I guess it's a disc braked bike?

    I doubt they're any lighter than QR though.
