Quantum GPS can help planes navigate when regular GPS is jammed

Published by skeptic

Quantum GPS could help future pilots navigate LightField Studios Inc./Alamy A quantum magnetic navigation system has been tested to guide an aircraft – and it outperformed standard backup systems that planes rely on when GPS signals are jammed. GPS and other global navigation satellite systems use radio signals transmitted between space and Earth. But these radio waves are relatively weak and are vulnerable to intentional jamming, as we saw in 2024 when GPS jamming and spoofing affected transatlantic flights. Now, GPS backup systems are becoming increasingly important as planes face navigational challenges. Article amended on 18 April 2025 We clarified that Q-CTRL is a quantum company Source link

Historic landmarks navigate an uncertain future after the LA fires : NPR

Prior to the Eaton Fire in January 2025, the Zane Grey Estate was a beloved historical and cultural landmark — the former home of Western novelist Zane Grey. Susan Pickering Photography/Teresa Fuller, Compass Real Estate hide caption toggle caption Susan Pickering Photography/Teresa Fuller, Compass Real Estate The former home of one of the world’s most famous western novelists, Zane Grey, was a Mediterranean Revival house designed with high, wood-beamed ceilings and airy balconies. “It had almost a cathedral vibe when you walked in,” said Nathaniel Grouille on a recent visit to the site. He bought the property with his wife in 2020. It’s been almost two months since the Eaton Fire destroyed thousands of homes in Altadena, including several noted historic and cultural landmarks like this one, which was listed on the National Register of Historic Places in 2002. During a visit in February, the shattered glass from the estate’s windows was still underfoot, along with blackened wood, twisted gutters and broken pieces of ceramic. All that the fire left standing are the sturdy concrete …

Nvidia’s ‘Cosmos’ AI Helps Humanoid Robots Navigate the World

Nvidia’s ‘Cosmos’ AI Helps Humanoid Robots Navigate the World

Published by skeptic

Nvidia announced today it’s releasing a family of foundational AI models called Cosmos that can be used to train humanoids, industrial robots, and self-driving cars. While language models learn how to generate text by training on copious amounts of books, articles, and social media posts, Cosmos is designed to generate images and 3D models of the physical world. During a keynote presentation at the annual CES conference in Las Vegas, Nvidia CEO Jensen Huang showed examples of Cosmos being used to simulate activities inside of warehouses. Cosmos was trained on 20 million hours of real footage of “humans walking, hands moving, manipulating things,” Jensen said. “It’s not about generating creative content, but teaching the AI to understand the physical world.” Researchers and startups hope that these kinds of foundational models could give robots used in factories and homes more sophisticated capabilities. Cosmos can, for example, generate realistic video footage of boxes falling from shelves inside a warehouse, which can be used to train a robot to recognize accidents. Users can also fine-tune the models using …

Organizing My Notes With Backlinks Has Made Them So Much Easier to Navigate

Organizing My Notes With Backlinks Has Made Them So Much Easier to Navigate

Published by skeptic

Key Takeaways Backlinking notes in your preferred app can improve organization and productivity. Using backlinks makes it easier to access important files and folders within your notes. Consider creating separate notes for unrelated topics, but use backlinks within related content for easier navigation. If your notes feel more like a chaotic web of information than an organized resource, you’re not alone. Without a clear system, it’s easy to get lost in the sea of scattered ideas and half-finished thoughts. This used to be my daily struggle—until I discovered the power of backlinking. What Are Backlinks, and Why Do They Matter in Note-Taking? Backlinks are in-text links that send you to another page. Since it’s easier than ever to take quick notes each day, backlinking is an excellent way to keep them organized. This is especially true if you don’t like using folders for notes or if your note-taking app doesn’t have folders in the first place. Most popular note-taking apps let you backlink your notes. An app like Obsidian takes this a step further, as …

‘Fields are completely underwater’: UK farmers navigate record rainfall | Farming

Published by skeptic

Farmers have been dealing with record-breaking rainfall over at least the past year, meaning food produced in Britain has fallen drastically. Livestock and crops have been affected as fields have been submerged since last autumn on account of it being an exceptionally wet 18 months. According to the Met Office, 1,695.9mm of rain fell from October 2022 to March 2024, the highest amount record for any 18-month period in England. Here, British farmers and growers tell us how they have handled the inclement weather conditions and what the heavy rainfall means for their immediate futures. ‘We are going to have an appalling harvest this year’ Tom Allen-Stevens, farmer and agriculture journalist. Photograph: Tom Allen-Stevens/Guardian Community Our farm is mainly arable so it’s crops that we grow. The constraints that we are facing this year means we are going to have an appalling harvest. We’ve hardly got any crops in the ground at all, I’ve only managed to get 30 hectares [74 acres] of my 170 hectares planted and we have 110 hectares of “croppable” land. …

Knot theory could help spacecraft navigate crowded solar systems

Knot theory could help spacecraft navigate crowded solar systems

Published by skeptic

Space modules must be able to switch orbits in order to explore a solar system Elen / Alamy Stock Photo When a spacecraft is circling a planet or sailing among a set of moons, navigating between different orbits can be tough – but a trick from knot theory may help. It can be used to identify points called heteroclinic connections, where a craft can transfer from one orbit to another without burning any of its precious fuel. “These heteroclinic connections, a lot of the time we know there are some for a pair of orbits, but… Source link

How generative AI can navigate misinformation and disinformation

How generative AI can navigate misinformation and disinformation

Published by skeptic

New research into generative AI images shows only over a third of media organisations surveyed at the time of research have an image-specific AI policy in place. The study, led by RMIT University in collaboration with Washington State University and the QUT Digital Media Research Centre, interviewed 20 photo editors or related roles from 16 leading public and commercial media organisations across Europe, Australia, and the US about their perceptions of generative AI technologies in visual journalism. Lead researcher and RMIT Senior Lecturer, Dr TJ Thomson, said most staff interviewed were concerned about the impact of generative AI on misinformation and disinformation. However, factors that compound the issue, such as the scale and speed at which content is shared on social media and algorithmic bias, were out of their control. He explained: “Photo editors want to be transparent with their audiences when these technologies are being used, but media organisations can’t control human behaviour or how other platforms display information.” Thomson said having policies and processes in place that detail how generative AI can be …

NASA Quietly Training Robot Dog to Navigate Landscape of the Moon

Published by skeptic

One small step for robot kind. Moon Walk NASA is teaching a robot dog how to walk on the Moon. With little fanfare, a multi-disciplinary team of researchers — including engineers, planetary scientists, and cognitive scientists — let loose a quadruped robot called Spirit at an altitude of 6,000 feet on the snowy and rocky hills of Oregon’s Mount Hood. The project called Legged Autonomous Surface Science in Analog Environments (LASSIE) is designed to teach the robot to adapt to its varying environment in real-time, with the goal of eventually having it traverse the surface of the Moon and perhaps even other worlds in our solar system. “A legged robot needs to be able to detect what is happening when it interacts with the ground underneath, and rapidly adjust its locomotion strategies accordingly,” said University of Southern California assistant professor of electrical and computer engineering Feifei Qian in a statement.
