Fetuses Caught Yawning In 4D

Rambo Tribble writes "Reuters reports 4D scans have conclusively shown that fetuses do yawn. Understandable, eh? After all, all they get is cable."

    It is supposed to mean it has height, width, depth and time.

    They're 2D images of 3D objects.

    Nope. Ultrasound gives complete depth measurements. So each time step is an (X,Y,Z) data cube (actually (theta,phy,time)->response ), where response is the magnitude of the received sound in the microphone. Therefore each elenment in the video is therefore the tuple (X, Y, Z, T)->some value, i.e. 4 dimensional.

    The video shown is just a projection, but ultrasound gives multiple depth readings, not just a single 2D manifold, so the raw data (obviously not the video here) is certainly 4D data.

    So yeah, ultrasound does provide full 4D data and the files are immense.

    Take it easy on him at least he's suggesting that some of us may be having sex. I for one am flattered.

    The fetus has a tiny Delorian in there with it.

    "Won't I run into the Uterus' wall?"

    "You're not thinking Fourth Dimensionally."

    "Yeah, I have a real problem with that."

    So do dogs. Cats yawn too. I'm not sure about mice.

    What's the point of this story, is there some burning question as to what organisms yawn? A yawning controversy I haven't heard of perhaps? Or some prospective line of in inquiry into the science of yawning?

    This story seems like a puff piece devoid of any significant detail or content worth posting to Slashdot.
