Johns Hopkins researchers use night vision tools and artificial intelligence to uncover a common set of rules
they are challenging. Athena for the knitting contest. Athena, angry that she found no flaws in Arachne's work—and also that the tapestry showed the gods in an unwelcome light—overcame the girl with a shuttle. When Arachne hanged himself out of remorse, Athena took pity on the rope and turned Arachne into a spider. p>
This is a fitting literary irony for a new study of how spiders weave their webs, which is undoubtedly why Johns Hopkins scientists referenced Ovid's story in a recent article in Current Biology. The JHU team used night vision and artificial intelligence to record the movements of several hack-weavers spinning their threads. The experiment showed that spiders rely on a set of common motions to create precise geometric structures that stem from a "gamebook or web-building algorithm" — even if their brains are very small compared to humans. p> <. Andrew Gordos, one of the authors, a behavioral biologist at JHU, said he was inspired to do the project while riding a bird with his son and saw an amazing spider web. "I thought, 'If you go to the zoo and see a chimpanzee making this, you think chimpanzees are amazing and impressive,'" Gordos said. It's small and I was disappointed that we don't know much about how it behaves. We've now defined the entire choreography for web design that hasn't been done before. For any animal structure with this decision. p> ad zoom A spider web has been hacked. Johns Hopkins University
In addition to being a stunning aesthetic of nature, spider webs form a kind of physical record for many, according to the authors. Which can determine the behavior of Weaving the ball, because the process of making the thread can be easily determined by the path of the spider and the geometry of the thread.
There are different types of threads.JHU chose to work with Uloborus Diversus, and the team chose a small U.also easily.Samples are collected in Hav Moon Bay, CA and kept in a greenhouse on campus D. There spiders eat fruit flies once a week. Only female spiders were used, as adult males rarely weave. p> Zoom in/ see a spider web with night vision. Johns Hopkins University
For real-world experiments, the team designed a lab plexiglass container lined with paper at the edges to encourage web construction, equipped with infrared cameras and infrared lights. (U. p>
This activity is usually followed by a well-defined progression. The spider begins to explore space before building an initial web that will not be part of the final structure. Consider an artist producing a rough design. The primary fibers are relatively unstructured, and there are long pauses Irregular in the spider’s activity as it builds its primary fibers—sometimes for eight hours, because you can’t hurry to inspire.” “This spinning mode is an exploratory stage in which the spider assesses the structural integrity of its surroundings and identifies the anchor points for the final spin.” The authors wrote.
Next, the spider goes to build. Radius and Frame for Web Writers: "The creation of the frame is often the result of installing the silk in the margin before going back, then out along the previous radius, pinning the silk frame at the end of the line, and then back to Axis.” Books. p> Zoom in / Use artificial intelligence to track the construction of a spider's web.

Once the beam and frame are in place, the spider builds an extra helix, which only takes a few minutes. Scientists believe this step will help stabilize the structure before the spider builds the final helix, because the helix is temporary. Usually the spider destroys the web when it is completed. When the spiral is completed, the spider hunts in the center, sometimes for several days, waiting to prey on prey in its web. p>
Researchers have been able to track millions of individual foot movements. . For this purpose, they designed their own vehicle vision software. "Even if you videotaped it, there are a lot of legs that have to stay for a long time," says Abel Korver, one of the article's authors, a graduate student studying web design and neurophysiology. It's very difficult to go through each frame and comment on the points on the feet manually, so we trained our machine vision software to detect the condition of the spider frame by frame, so we could document everything the legs do to make a chain.
