Biohybrid fish made from human cardiac cells swims like the heart beats

I was intrigued, and then noticed that “fish” should be in quotes; they’re not fish, they’re cardiac cells on a synthetic fish-shaped scaffolding.

Still cool nonetheless.

Device shaped as a fish that includes a chunk of human cardiac cells, moves as expected in human muscle. The "biohybrid" term is just here to confuse.

Has anyone found the paper? I’m trying to understand how they entrained the cardiac cells.

I’m writing a paper about the relationship between resonance and entrainment, arguing that entrainment is a special type of resonance based on self-sustained oscillators.

There is a Science link somewhere in the middle of the article: https://www.science.org/doi/10.1126/science.abh0474

It’s not on a sci-hub, though

This is very cool. It should be possible to scale this up and build artificial hearts.

I dunno, having a tank full of "fish" made of my own cells? Has a nice cyberpunk feel to it.

The more fascinating use is to build artificial fish.

[cosheaf → klntsky]

Yes, that's clearly much more fascinating than saving lives with artificial hearts.

This makes All Tomorrows feel a lot less farfetched.

Should say that the future of medicine is fishy, but it's not a real fish
