Great news: we're excellent at curing mice of diseases. All this time we've been trying to find drugs that have the same effect in humans as they do in mice, but until now no one has had the insight or bravery to ask the question, "What if we just made people more mouse?" Exciting stuff.

  This is making mice more people, but either way it's an exciting day for mice everywhere.

    Not really, since this is just inventing new and exciting ways to give mice more brain diseases

    As if mice didn’t have enough of their own brain diseases!

    There actually exist mice facial expression amplifiers (and sound clarifiers etc.). If we employed them, we could get a better insight on their quirks and difficulties.

    Not really. Soon they will be paying taxes just like us and I'm not sure they're going to like it.

> The scientists said their work, published in the journal Nature, was carried out with independent ethical scrutiny.
oh, I guess there's nothing to be concerned about.
1. rf15 · 1789625675 · focus · HN ↗
  I think you just misread that - the adjective independent refers to ethical, not scrutiny /s

Does this remind anyone of that novel Flowers for Algernon..?

  That story was so sad, reading it was like actually going through the process together with the main character.
  The past few years I seem to be seeing more and more experiments with growing brains in laboratories. Aren't there laws regulating bioethics that forbid such questionable practices? Not that laws ever stopped determined nation states or private researchers from pursuing knowledge - or profit, or competitive advantage - at any cost.
  I imagine some would argue there is no ethical problem, because these brains do not experience suffering like humans do. But how do you know for sure?

    > Aren't there laws regulating bioethics that forbid such questionable practices?
    Not generally, no. Most of it is by convention coupled with the fact that no reputable journal will publish your work these days if you don't go through an IRB for certain types of work. There's also the funding angle, with most work being paid for by one of a few very large governmental bodies and each of those having stringent rules about what they do and don't permit.

    > But how do you know for sure?
    Presumably by intelligent, competent, analytical direct consideration.
    The non-layman should get a pretty good idea at assessment (in this case, "where is nociception and is it there" etc.)
    Allow me a relatively distant reference, for fun. Prosecution: "How do you know the patient was dead at the time?" // Doctor: "Because his brains were sitting on my table" // "And can you know for sure he was dead?" // "He could have been alive, brainless and practicing law maybe".
    Which wants to mean, at least: surely there are subtle non easy questions, but still there exist thresholds of competence enabling better assessment.

I feel like it's going to be difficult to characterize how mental illness translates to mice, even if you get human cells in there. ("psychiatric diseases" = mental illness)

Sounds like “the scret of NIMH” an animated movie from the 80s, where intelligent mice escape a science lab.

> While mice with brains that are partly human might sound like a Kafkaesque experiment, the scientists said these are not "mice that think like humans".
oh, thank god

The article walks the headline back pretty quickly. Parts of human brains in mice becomes "pieces of brain-like tissue" made from skin cells and formed into "collections of connected, living cells" followed by a line on how there's "no indication that what's being created here are mice that can think like humans, or a human brain in a mouse body."
It's still kind of neat though and I hope it's actually somehow useful for something.

So now we have found a way to use brain organoids by grafting and growing them inside mouse heads. Those Frankenmice will be used as a platform from now on.
I m looking forward to talk to the first language-capable Frankenmouse.

Humans genetically-engineered with no cerebral cortex fitted with a whole bunch of computing technology the craniums - coming to a city near you soon.
Oh, wait, has that already happened, and you thought someone was going to tell you about it? They thought they couldn't fake all the head MRI scans to cover up for THAT?
Multiple variations of this reality may exist. I'd so read a thriller book about this...but none have been written, strangely enough.
