“Ghost” stars are aligned in beautiful structures near the centre of our galaxy, scientists say – and they might finally be getting to know why. Researchers discovered the unusual alignment of these planetary nebulae ten years ago, when Manchester doctoral student Bryan Rees spotted them. But it has remained a mystery how they came to be that way. Now scientists have been able to confirm that unusual alignment. But they have also made a breakthrough in finding out why they are there, after they found that a particular group of stars known as binary stars is responsible. Planetary nebulae are gas clouds that are thrown out from stars when they come to the end of their life. Our own star, the Sun, will do the same in about five billion years. Those ejected clouds are like ghosts of their dying stars, and assemble themselves in beautiful shapes, researchers say, such as an hourglass or butterfly. Researchers studied a range of planetary nebulae that are near the centre of our Milky Way. Though they are not related and come from different stars and different times, many of their shapes are similar, lining up in the same way and on the same plane. In the new study, scientists found that the alignment happens when those ghosts have a close companion star. The companion orbits around the main star, at the centre of the planetary nebulae, at a very close orbit. Without such a companion star, the nebulae do not line up in the mysterious pattern. That suggests that the alignment is linked to the splitting of the binary components when the star is born. “This finding pushes us closer to understanding the cause for this mysterious alignment,” said Albert Zijlstra, co-author and professor in astrophysics at The University of Manchester. “Planetary nebulae offer us a window into the heart of our galaxy and this insight deepens our understanding of the dynamics and evolution of the Milky Way’s bulge region. “The formation of stars in the bulge of our galaxy is a complex process that involves various factors such as gravity, turbulence, and magnetic fields. Until now, we have had a lack of evidence for which of these mechanisms could be causing this process to happen and generating this alignment. “The significance in this research lies in the fact that we now know that the alignment is observed in this very specific subset of planetary nebulae.” Researchers looked at 136 confirmed planetary nebulae in the galactic bulge, or the thickest section of our Milky Way. They used the European Southern Observatory’s Very Large Telescope, and then looked at 40 more of them using images from the Hubble Space Telescope. The findings are reported in a new paper, ‘When the Stars Align: A 5 σ Concordance of Planetary Nebulae Major Axes in the Centre of our Galaxy’, in the Astrophysical Journal Letters.

An artificial intelligence system has achieved a key milestone by winning multiple races against three world-class drone-racing champions, marking the first time AI has beat humans at a physical sport. The AI system called Swift, developed by researchers from the University of Zurich in Germany and Intel, could prove its mettle in first-person view (FPV) drone racing – a sport in which pilots fly quadcopters at speeds exceeding 100kmph. Until now AI systems have achieved a number of remarkable victories over humans in a range of strategy-based games, including IBM’s Deep Blue winning at chess against Gary Kasparov in 1996 and Google’s AlphaGo defeating top Go champion Lee Sedol in 2016. However, physical sports are more challenging for AI as they are less predictable than board or video games. “We don’t have a perfect knowledge of the drone and environment models, so the AI needs to learn them by interacting with the physical world,” Davide Scaramuzza, one of the authors of the study from the University of Zurich, explained. AI-driven autonomous drones have until now taken twice as long as those piloted by humans to fly through racetracks unless an external position-tracking system was used to precisely control their trajectories. But the new Swift AI drone, described in a new study in the journal Nature, has demonstrated that it can react in real-time to the data collected by an onboard camera, just like the one used by human racers in the sport. Sensors on the drone measure acceleration and speed while the AI system uses data from the camera to locate the drone in space and detect the gates along the racetrack. A control unit in the drone, also based on AI, a control unit, then chooses the best action to finish the race circuit as fast as possible. Researchers say the Swift drone trained itself to fly in a simulated environment by trial and error. Using simulations, scientists could avoid destroying multiple drones in the early stages of learning when the system often crashes. “To make sure that the consequences of actions in the simulator were as close as possible to the ones in the real world, we designed a method to optimise the simulator with real data,” study first author Elia Kaufmann said. During the testing phase, the drone flew autonomously using very precise positions provided by an external position-tracking system, while also recording data from its camera. By comparing the two data sets, Swift could learn to autocorrect errors it made in interpreting information from the onboard sensors, scientists say. The AI was soon ready to challenge some of the world’s top human drone pilots – the 2019 Drone Racing League champion Alex Vanover, the 2019 MultiGP Drone Racing champion Thomas Bitmatta, and three-time Swiss champion Marvin Schaepper. In races that took place between 5 and 13 June 2022, on a special track designed in a hangar of the Dübendorf Airport near Zurich, Swift achieved the fastest lap, with a half-second lead over the best lap by a human pilot. The special track – about 25 by 25 meters in dimension – was built with seven square gates that had to be passed in the right order to complete a lap. Drones had to execute challenging maneuvers to successfully finish the track, including an acrobatic “Split-S” feature that involves half-rolling the drone and executing a descending half-loop at full speed. While Swift could record the fastest lap, humans are more adaptable than the AI drone, which failed when the conditions were different from what it was trained for, scientists say. However, they add that the new breakthrough in AI flight is an important way beyond drone racing. “Drones have a limited battery capacity; they need most of their energy just to stay airborne. Thus, by flying faster we increase their utility,” Dr Scaramuzza said. The new research, according to scientists, may lead to better drones for forest monitoring or space exploration, and in cases where flying fast is important to cover large spaces in a limited time. They say fast AI drones could also be used for shooting action scenes in movies and may also “make a huge difference” for rescue drones sent inside a burning building.

READING, Pa.--(BUSINESS WIRE)--Jul 10, 2023--

Apple has released a new iPhone update that ensures they won’t break when being charged in the car. The iOS 17.1.1 update includes a range of bug fixes for some unusual and high-profile issues with Apple’s new iPhones. It is available to download now as usual. When the iPhone 15 was released, some users of specific cars – particularly those made by BMW and Toyota – reported that charging their phones in the car would break them. In some cases, when people used the built-in wireless charging then Apple Pay would stop working, for instance. That is now fixed in the new update, according to Apple’s release notes. It fixes an issue where “In rare circumstances, Apple Pay and other NFC features may become unavailable on iPhone 15 models after wireless charging in certain cars”, it says. The new operating system update also fixes an issue where “Weather Lock Screen widget may not correctly display snow”, the release notes say. That refers to a problem where users would instead see a file icon, which had been widely reported. Apple has also released an update for the Watch, numbered 10.1.1. That fixes another prominent issue that led to unexpected battery drain on the Watch, with some reporting that their devices lost all their charge in just a few hours. The Mac and HomePod also have their own bug updates. They can all be installed as usual: through the Settings app on the iPhone or Mac, or through the devoted apps for the Watch and HomePod, though all devices should eventually prompt the user to update automatically. The update came after a Bloomberg report that indicated Apple had taken some engineers off work on upcoming major updates to ensure that the current operating system versions were as free of bugs as possible. Recent weeks have seen a range of unexpected bugs in Apple software, including widespread reports that the iPhone 15 would get uncomfortably hot, which was later fixed with another software update.
