It’s able to swim through the water like a real fish can, but without any intelligence guiding its path. That wasn’t why the tiny fish automaton was created, however. Instead, researchers at Harvard and Emory University are using it as the groundwork towards growing organic artificial hearts one day.
The fish’s design features a flexible tail that’s covered in a layer of heart muscle cells (cardiomyocytes derived from stem cells) on each side. When the cells on one side contract, it pulls the tail in that direction, and when the cells on the other side contract, it pulls the tail in the opposite direction. But what’s particularly interesting about this biohybrid is that the two layers of muscle cells are continuously triggering each other. When one side contracts, it causes the other side to stretch, and the stretching action opens a “mechanosensitive protein channel” that causes that side to contract, which in turn stretches the other side, and the process repeats.
The robo-human-fish also features a simple pacemaker-like mechanism that autonomously regulates the frequency and rhythm of these contractions so the tail has a proper back-and-forth motion to propel it through the water. Without any additional inputs, the muscle cells functioned as a closed-loop system and were able to propel the fish for over 100 days. Furthermore, like the muscles in your body improving with exercise, the biohybrid fish got better and better at swimming as time went on, until it was able to move through the water at speeds similar to a zebrafish.

They say that as if there is nothing horrific about it.
Where did they get the human heart cells?
Do they come with lasers?
Brainless fish….
Aren’t there enough Democrats already?
Just out of college, I worked in a research lab that studied the nervous system. One time, someone died who donated their body to medical research. Our lab received the heart to harvest cells and grow in culture. That’s where they come from... We looked at the effects of medicines on the heart by puffing drugs being studied on to the cells and monitoring the Na/Ca channels in the heart via patch clamping.
You don’t mess with God’s creation. There will be a pay day some day. . . just sayin’.
I draw the line at “The Human Centipede”.
Did it cost 6 million dollars?
Reading the article it sounds like the heart cells were derived from human stem cells. These most likely came from an adult which is not unethical. Aborted baby stem cells is profiting from murder - evil. However, they have found adult stem cells actually work much better for research with the added benefit that no one needs to be killed.
Why?
How do you know whomever that person is was responsible for the cells used in this experiment?
Imagine if something human produced like this gets loose in nature and predominates. Kinda like the Wuhan virus...
I only have one question...
WHY???
I’m just here for the cyborg fish sticks.
Rhetoric much?
Babies.
They're made out of pilot fish, but the pilot fish are all running Flight Simulator.
