They created a device which they can successfully and safely move through blood vessels in the brain without causing injury and you characterize it as "Some college guys move coated wire with magnets"?!

I mean yes. Sort of like saying a covid vaccine is "some people mixing chemicals in test tubes".

Not quite.

The researchers also tested the thread in a life-size silicone replica of the brain’s major blood vessels, including clots and aneurysms, modeled after the CT scans of an actual patient’s brain.

So no, not a brain. Silicone tubes. On a table somewhere.

They're happy to talk it up like its an actual in-vitro human brain though.

Sure - you need ethics approval to do the studies on a live brain, but you don't on a replica.

The point remains.
