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
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
