Astronomers Discover a New Kind of Cosmic Object: a Black Hole 'Star'

Astronomers using the James Webb Space Telescope say they may have found a new class of object: a "black hole star," in which a black hole is wrapped in dense gas and radiates in ways that resemble an enormous star. The Guardian reports: The international team made the breakthrough after focusing their attention on a mysterious red spot in images of the early universe captured by Nasa's James Webb space telescope. The object was lurking in the constellation of Cetus, the Whale, billions of light years from Earth. It is thought to have formed 660m years after the big bang, astronomers' leading theory as to how the universe began. Measurements of the exotic body found that while it resembles an immense star, it releases 100bn times more energy than any known star can produce. The energy output is far closer to that observed from black holes than stars. The findings have been published in the journal Nature.

Meta Patents AI Glasses to Use Facial Recognition to Identify People, Make Highlight Reels of Your Dinner Party

Meta has patented a smart-glasses system that could use facial recognition to identify people and automatically create personalized highlight reels of events such as dinner parties. The patent doesn't guarantee the feature will ship, but it offers a detailed look at how Meta is exploring facial recognition and AI-powered memory capture for its wearable devices. 404 Media reports: "I've generated some highlights of tonight's dinner party. Would you like to see them?" a prompt from the system says, alongside various thumbnails of what look like people laughing, according to one illustration in the patent. One section says the system may personalize highlight files using "user relationship data." The illustrations clearly show a person wearing a pair of glasses, looking at a group of people, then the glasses focusing on one or more people in particular. Patentlyze, an organization that tracks patents, first alerted 404 Media to the patent on Friday. The patent is dense with how such a system would work, but in sum, the system with one or more cameras receives an input from the user, then uses machine-learning and "sensory data" to figure out points of interest in the camera's field of view. That can include detecting people in the shot "based on one or more facial recognition algorithms," identifying those specific people, detecting their facial expressions, using "eye gaze data of the user captured by the client system," and figuring out other points of interest "based on scene and semantic understanding." Although the patent is for "particular camera-based tasks by particular systems in a particular manner" -- in this case, the company's smart glasses -- Meta writes it "contemplates assisting users in any suitable camera-based task by any suitable system in any suitable manner." Meaning that although this technology is focused on the glasses, maybe the company will use it for other purposes in the future.

Robots That Walk and Talk Are Coming To Car Factories

An anonymous reader quotes a report from The New York Times: At a BMW factory in South Carolina, a human-shaped robot with a screen for a face recently stepped from a charging station toward a stack of green plastic boxes. It grasped an auto part from one of the boxes, pivoted, placed the part in a trolley, then pulled the trolley across the floor. The robot's slow, stiff movements suggested a worker with a bad hangover rather than a technological revolution. "They're still slower than humans," Ulrich Wieland, a BMW vice president in charge of logistics at the factory, in Spartanburg, told reporters invited to see the robot in June. But, he added, "they're advancing fast." Automakers have used robots for decades, but they are usually powerful, one-armed machines that are fixed in place and perform repetitive tasks like welding body frames or applying adhesives to door panels. Now, most major automakers are betting that robots designed to resemble human beings, known as humanoids, will usher in a new wave of automation and efficiency. Equipped with artificial intelligence, they are expected to move around and do tasks now done by humans without any modifications to factories or heavy equipment. Unlike most of the robots now in use, humanoids would respond to voice commands and theoretically solve problems and react to unforeseen events. They would never take a lunch break, join a union or require health insurance. To optimists, robots could rescue U.S. manufacturing by increasing productivity, solving shortages of skilled workers and giving Western carmakers a fighting chance at competing with Chinese rivals that enjoy lower costs. Boring but important jobs like sorting parts would be done by robots, freeing humans for more interesting and specialized work.
