“I grabbed him and said, ‘John, I think I can build a jellyfish.’"
A group of Harvard researchers have "reverse-engineered" a lifeform by building an artificial jellyfish (dubbed a "medusoid) using silicone and cells taken from a rat's heart. More video and info at the Harvard Gazette.

“I think that this is terrific,” says Joseph Vacanti, a tissue engineer at Massachusetts General Hospital in Boston. “It is a powerful demonstration of engineering chimaeric systems of living and non-living components.”
He then removed a small human baby from the mini fridge next to his desk and proceeded to devour it with an air of bemused detachment. Patrick declined to partake in the snack, as he was still full from the afternoon harvest.
The team now plans to build a medusoid using human heart cells. The researchers have filed a patent to use their design, or something similar, as a platform for testing drugs. “You’ve got a heart drug?” says Parker. “You let me put it on my jellyfish, and I’ll tell you if it can improve the pumping.”
They also hope to reverse-engineer other marine life forms, says Parker. “We’ve got a whole tank of stuff in there, and an octopus on order.”

This is not an animal. It's a single tissue type that cannot grow, self-regulate, respond to its environment, or do anything aside from pump its little flappers. It's a neat demonstration, but the article could do without the sensationalism.

Yeah it's definitely sensationalistic but it's a pretty sensational demo to be honest. I mean, it certainly looks for all the world like a jellyfish. I mean, superficially. It's obviously not an actual animal any more than a culture of rat muscle cells on a regular ol' petri dish is an animal. Still, it's a very dramatic demonstration, and it's pretty neat that they were able to grow a cell culture that actually does something.
This isn't the first time that someone has been able to do that, though. The one that I remember hearing about best is from back in 2004 and it was actually a culture of rat brain cells that they got to do things – in that case, they got them to pilot an F-22 Flight Simulator. Pretty weird stuff that, because unlike here where the muscle cells are just doing what they do in response to an electric field, the researchers actually were able to train their culture to respond appropriately to stimuli (inputs) and then output an appropriate response. To the extent that a petri dish with a thin smear of rat brain on it is conscious, the culture actually perceived the simulator as its reality and interacted with it in a purposeful way. Now that is some weird, weird stuff there.

I don't really understand the big deal with these things. Isn't it common knowledge that muscle cells contract due to electrical stimulation? These researchers have put a layer of muscle cells on a sheet and pulse electricity through them to contract the muscle cells. I don't know what would have been expected to happen other than this.

This is like saying the mountain god is angry when it rains. What there is is a flimsy setup that after much manipulation can be coaxed into producing the miniscule effect that the entire project was set up to demonstrate in the first place. Words like "perceive" and "reality" and "interact" just serve to inject pre-ordained meaning onto it. It's a hallucination.
