Re: Engineered material can reconnect severed nerves

I've always found it incongruous that we can move a person's body around the globe at 900 kilometers per hour for 25 hours for under $1500 but for 1000x that price and even with 1000x that time we can't bridge the distance between a brain and a foot.

These seem completely unrelated. One is about travel distance the other is about forming tissue connections. We can easily travel the distance between brain and a foot, it's around 5 ft.

I'm not a medical person, can anyone who knows more than me explain exactly how cool this is? Fixing spinal cords, or just repairing simple nerve severance?

I too am interested in the applications of this technology and also what the timeline for that might look like.

The class of problems that falls under the category of movement of matter is fairly trivial.

Repairing severed nerves is more like an entropy-reversal class problem. I don’t think we could even put a sufficiently broken tea cup back together exactly as it was.

Earlier quoted context omitted.

The fact that they grow back in place makes the whole thing 1000x easier, no?

Only if it grows back correctly! Imagine attempting to wire up a datacenter that is actively trying to rewire itself (and not necessarily to your plans).

here's the kicker

it's all connected to an organic deep neural network

which means that the specific arrangement of the physical wires doesn't matter. because there's a training period in which the neural network literally learns to control the body anyways

University hosted announcements (e.g. rice.edu announces a major breakthrough) have incentives that are so out of wack it's basically clickbait at this point.

Researchers oversell their results for publishing and funding purposes. Then the university oversells those results to draw in students/investors.

Curious if others feel the same way or if I'm just too cynical at this point...

Some things turn out to be hard to do.

Yes, and a lot of those things are done.

It's just interesting the way we've progressed.

Except the arrangement starts to matter more and more with age.

If we only ever wanted to reconnect nerves of fetuses that might be relevant.

30 % of physics and chemistry can’t be replicated. 70 % of soft science can’t be replicated. Most of what we know about sociology may just be fake, and given that a huge foundation of progressive thought around rase, sex, and gender is based on this, this is a big problem.

at a minimum, this isn’t far off

I understand the cynicism. Academic reporting is a hard & thankless gig.

The non-cynical version: Half of a researcher's job is disseminating results -- to other researchers & the populace at large. I'd much rather have excited university announcements (even over-reaching ones) than the rage-porn news that dominates the airwaves & "mainstream news" homepages.

Besides: Any serious researcher will just revert to the actual peer-reviewed source material. It was linked in the article. Here it is: https://www.nature.com/articles/s41563-023-01680-4

And here's the PDF: https://www.biorxiv.org/content/10.1101/2022.01.24.477527v2....

As someone who has peripheral knowledge in this space (piezeoelectric & magnetostrictive devices and neural stimulation & recording): I've never seen a magnetostrictive material capable of developing a DC bias. Further, driving the device in a non-resonant mode for neural stimulation is even more new to me -- that's quite fascinating, and I'd say that article lives up to the hype from my 1000-ft vantage. I.e. This was effective reporting.
