Technology news

	A method to enhance the planning of missions completed by multiple UAVs Unmanned aerial vehicles (UAVs), also known as drones, have already proved to be valuable tools for tackling a wide range of real-world problems, ranging from the monitoring of natural environments and agricultural plots to search and rescue missions and the filming of movie scenes from above. So far, most of these problems have been tackled using one drone at a time, rather than teams of multiple autonomous or semi-autonomous UAVs.
	Optimal system for reusing construction materials includes local storage, a new study of Amsterdam suggests Building construction accounts for a huge chunk of greenhouse gas emissions: About 36% of carbon dioxide emissions and 40% of energy consumption in Europe, for instance. That's why the European Union has developed regulations about the reuse of building materials.
	Researchers create skyrmion-based memory technology for extremely low-power devices A research team led by the Agency for Science, Technology and Research (A*STAR) in partnership with National University of Singapore (NUS) has created an innovative microelectronic device that can potentially function as a sustainable, high-performance "bit-switch." This paves the way for future computing technologies to process data much faster while using significantly less energy.
	3D images reveal link between crack complexity and material toughness The last time you dropped a favorite mug or sat on your glasses, you may have been too preoccupied to take much notice of the intricate pattern of cracks that appeared in the broken object. But capturing the formation of such patterns is the specialty of John Kolinski and his team at the Laboratory of Engineering Mechanics of Soft Interfaces (EMSI) in EPFL's School of Engineering.
	Machine 'unlearning' helps generative AI forget copyright-protected and violent content When people learn things they should not know, getting them to forget that information can be tough. This is also true of rapidly growing artificial intelligence programs that are trained to think as we do, and it has become a problem as they run into challenges based on the use of copyright-protected material and privacy issues.
	Top computer scientists say the future of artificial intelligence is similar to that of Star Trek Leading computer scientists from around the world have shared their vision for the future of artificial intelligence—and it resembles the capabilities of Star Trek character "The Borg."
	Apple's 'Walled Garden' under fire in lawsuit Call it a "walled garden" or an ecosystem, but at the heart of Thursday's blockbuster US lawsuit against Apple are the many ways the company gets customers to remain faithful to its products.
	TikTok's duet, green screen and stitch turn political point-scoring into an art form Since its astronomical rise in popularity during the 2020 COVID-19 lockdowns, TikTok has played an increasing role in all aspects of American life, including politics, from the White House briefing key TikTok creators on the war in Ukraine to Joe Biden's presidential campaign launching a TikTok account.
	Lightweight machine learning method enhances scalable structural inference and dynamic prediction accuracy In recent strides within machine learning technology, particularly in reservoir computing (RC), notable advancements have been made in understanding complex systems across various domains. Researchers have been tirelessly innovating machine learning methods to analyze and forecast the dynamic behaviors of intricate systems using observed time series data. However, a pressing challenge persists: how to uphold a lightweight model while harnessing more structural information to achieve precise predictions of complex dynamics.
	Thin, bacteria-coated fibers could lead to self-healing concrete that fills in its own cracks Some say there are two types of concrete—cracked and on the brink of cracking. But what if when concrete cracked, it could heal itself?
	AI's excessive water consumption threatens to drown out its environmental contributions Water is needed for development, production and consumption, yet we are overusing and polluting an unsubstitutable resource and system.
	Major environmental benefits of recycling gold with biodiesel Researchers at Chalmers University of Technology in Sweden have developed an environmentally friendly method for recycling and purifying metals. Using gold earrings from a pawnshop in Gothenburg and biodiesel from the nearest filling station, the discovery could change an industry that is currently dependent on large amounts of fossil oil.
	Meta's success in suppressing misinformation on Facebook is patchy at best, finds study The content moderation policy adopted by Meta at the time of the COVID-19 pandemic to rein in misinformation on Facebook has proved no great obstacle to users capable to finding work arounds according to a new study by digital and social media researchers from the University of Technology Sydney and the University of Sydney.
	What the DOJ's antitrust suit against Apple means for everyone with an iPhone Cheaper app subscriptions. Additional payment options. Greater freedom for app developers on the App Store. More consumer choice.
	Forced labor in the clothing industry is rampant and hidden. This AI-powered search platform can expose it Almost all of the clothing sold in America comes from overseas, making a long journey on a shipping container into a domestic port. Peer inside any apparel shipment bound for customs checkpoints, groaning with t-shirts or leggings or underwear, and you'll probably see tags hinting at their origins: Made in Vietnam, China, Indonesia.
	Additive manufactured aluminum alloys for space optical instruments When Zach Post was approached about leading a study to develop a framework for additively manufacturing (colloquially called 3D printing) a new space instrument for detecting air pollution, it was an opportunity he couldn't pass up.
	Could supersonic flights be the next big thing in air travel? This flight expert isn't so sure If you could fly from New York to London in half the time, would you? With a renewed interest and investment in commercial supersonic flight, that's what some companies hope to achieve.
	New structure transistors for advanced technology node CMOS ICs A review published in the journal National Science Review summarizes the research of a team led by Prof. Huaxiang Yin (Institute of Microelectronics of Chinese Academy of Sciences). They systemically reviewed the development history of Si-based metal-oxide-semiconductor field-effect-transistors (MOSFETs), including the theory update, new materials introduction, key processes breakthrough, especially on device structure innovations for the development of advanced integrated circuits (ICs) in the past twenty years.
	Amazon under investigation for selling illegal electronic devices Amazon is currently being investigated for selling illegal electronic devices, including radio signal jamming devices that can be used to confuse drones, thwart security systems and interfere with Wi-Fi networks.
	Cogeneration of innovative audio-visual content: A new challenge for computing art Walter Benjamin came up with aura and authenticity in "The Work of Art in the Age of Mechanical Reproduction" in 1936 to describe the value of original artworks created by artists instead of mechanical copies. He wanted to defend artificiality and support traditional fine arts.
	Apple, Google and Meta set to face probes under new law: source Apple, Google and Meta are set to face the EU's wrath next week as Brussels prepares to hit the tech giants with probes into potential violations of a landmark law, sources close to the matter said Friday.
