James sez, "Mini-milestone in the OpenWorm Project, the collaborative, open source attempt to construct an artificial life form from the cellular level to the point where it's able to have basic problem-solving abilities. They've now artificially recreated internal muscle sensation, a building block for movement, entirely through code -- watch the eerie video!"
"The core algorithm for the physics simulation is called PCI-SPH, which is a somewhat advanced but well understood particle simulation method. The main source of complexity is the architecture: going from brain firing signals to muscle contractions to moving particles around."
So yes, it accurately simulates the muscle algorithm for these kinds of worms:
"Any time you do a simulation like this you're trying to make intelligent abstractions," John allows. "Unless you are simulating from first principles and moving quarks and gluons around, you're going to be glossing over some detail. So you try to make an abstraction that captures the essence of what you think is happening under the hood, and measure the results. In this case, the muscle model matches a basic level of our understanding of brain to muscle signaling and the physics of contraction/expansion in this worm, and the output (how the worm moves, displaces liquid, etc) looks pretty close to the real-world measurements!"
Artificial Life Milestone: OpenWorm Team Recreates Internal Muscle Sensation Entirely Through Code
That point of light between Saturn’s rings is Earth, captured by NASA’s Cassini spacecraft on April 12. More about the image here at NASA JPL. It reminds me of the last photo taken by the Voyager I spacecraft before engineers shut off its imaging systems. Carl Sagan had persuaded NASA to turn Voyager I’s cameras […]
As AI improves, the mystery of consciousness interests more programmers and physicists.
Most of us need a computer interface implanted in our brains like we need a hole in our head. That said, there are benefits to bridging the gap between mind and machine. Joel Murphy is the founder of OpenBCI, an inexpensive, and non-invasive, brain-computer interface (BCI) platform. People have used OpenBCI to control robots, compose […]
They probably just sleep a lot. But still, you can remotely keep an eye on them when you’re at work and missing them deeply with this HD monitor from Kodak.If you have a new puppy that destroys everything in sight, or you just want to be a little more security-conscious, this WiFi camera is a […]
Thinking of a business idea is the easy part. Doesn’t even have to be a “good” idea, you can still get people to throw money at a non-existent venture, but to do that you need to at least have something even resembling a viable business plan. Why doesn’t anyone do it then? Because building that semi-viable […]
The Twisty Glass Blunt is an intriguing product that claims to abolish the need to ever buy or use rolling papers. And, well, it does if you so choose. You can cut down on the waste this 4/20, and everyday after when you’re smoking with this clever piece.Built with a German-engineered glass tube and inner […]
