    It is probably not a coincidence that the single celled creature they
    used for this was an ancient flagellate. They were the first living
    things to actually have a viable protein motor of sorts and a whip tail
    which gave them their name.

    Last common ancestor still with genes close enough to work in a mammal.

    There may well be fungi or slime moulds similarly capable of this trick.

    I just hope we get a positive for life on Mars soon,
    one that is accepted by the religious Adam and Eve came first doctrine club ! And if they find life, what religion does it have?

    Maybe it will lessen the differences we see now that are used for war mongering by some world powers.

    OTOH I did read today that reading is getting bad for a lot of schools here... Lots of immigration, kids not used to reading anymore? Just selfies and youtube?
    By the time most of Africa has moved here we *are* in Africa..

    Nuclear war possible, personally I would have nuked Kiev long ago..
    The evil COVID shots that caused ByeThen's brain to detoriate
    make him OK long range US missiles used by YouCrane to attack Russia.

    Drifting of the topic here .... Well it is all over the news..

    Rebuild all later? Planet of the apes?
    Will they dig up the Statute of Gibberish and try to figure out how our brains worked, evolved, a million years from now?
    ;-)

    The article title is, if not actually misleading, inclined to mislead.

    An uninitiated reader might construe this as meaning that the
    researchers more or less created a mouse from scratch. But it's clear
    that that's not what happened. Rather, they've taken a non-stem cell
    from a mouse and created a mouse stem cell from it.

    I chased down the underlying article, which was unlocked for all. The
    article made sense. I think the problem with the Science Daily
    article is that the writer had no idea what they were looking at.

    What was done is that an ancient functional piece was installed in a
    modern mouse egg replacing the modern descendent of that piece, and it
    still worked normally in the resulting mouse pup. This piece is quite
    ancient, and yet has remained essentially unchanged to this day.
