Technology news

	An architecture for sub-picowatt logic computing based on self-biased molybdenum disulfide transistors The continuous improvement of circuits and electronic components is vital for the development of new technologies with enhanced capabilities and unique characteristics. In recent years, most electronics engineers have been specifically focusing on reducing the size of transistors, while retaining a low power consumption.
	Engineers develop promising calcium-based battery that's rechargeable and operates at room temperature A multi-institutional team of Chinese engineers has developed a proof-of-concept calcium-based battery that withstands 700 charge cycles at room temperature. In their paper published in the journal Nature, the group describes the challenges they addressed in developing the battery and what they have learned about the possible use of calcium-based batteries in consumer products in the future.
	Science fiction meets reality as researchers develop techniques to overcome obstructed views After a recent car crash, John Murray-Bruce wished he could have seen the other car coming. The crash reaffirmed the USF assistant professor of computer science and engineering's mission to create a technology that could do just that: See around obstacles and ultimately expand one's line of vision.
	The YouTube algorithm isn't radicalizing people, says bots study About a quarter of Americans get their news on YouTube. With its billions of users and hours upon hours of content, YouTube is one the largest online media platforms in the world.
	Improving traffic signal timing with a handful of connected vehicles With GPS data from as little as 6% of vehicles on the road, University of Michigan researchers can recalibrate traffic signals to reduce congestion and delays at intersections significantly.
	Adaptive smart glove can teach new physical skills You've likely met someone who identifies as a visual or auditory learner, but others absorb knowledge through a different modality: touch. Being able to understand tactile interactions is especially important for tasks such as learning delicate surgeries and playing musical instruments, but unlike video and audio, touch is difficult to record and transfer.
	Wind-powered Dutch ship sets sail for greener future The world's first chemical tanker ship fitted with massive rigid aluminum "sails" has left Rotterdam, its owner hoping to plot a route to bringing down the shipping industry's huge carbon footprint.
	Senior Czechs refine Wikipedia as retirement hobby A frail 80-year-old retiree does not fit everyone's idea of a tech-savvy Wikipedia writer, but Jirina Kadnerova is a devoted contributor to the online encyclopedia.
	Edible electronics are being developed to assist rescue operations and go inside hospital patients Professor Dario Floreano is a Swiss-Italian roboticist and engineer engaged in a bold research venture: the creation of edible robots and digestible electronics.
	Apple set to face near €500 million EU fine in Spotify row Apple Inc. will face a European Union fine close to €500 million ($539 million) over the regulator's investigation into allegations it silenced music-streaming rivals, including Spotify Technology SA, on its platforms.
	What is Sora? A new generative AI tool could transform video production and amplify disinformation risks Late last week, OpenAI announced a new generative AI system named Sora, which produces short videos from text prompts. While Sora is not yet available to the public, the high quality of the sample outputs published so far has provoked both excited and concerned reactions.
	Distributed energy resource cybersecurity framework tool shines in solar cybersecurity assessment As the world pushes for sustainable energy, the spotlight turns to distributed energy resources (DERs), with solar photovoltaic (PV) systems at the forefront. In the quest for decarbonization, a shining star emerges—the Distributed Energy Resource Cybersecurity Framework (DER-CF).
	Regulatory tech costs can have benefits, too RegTech might be one of the biggest new industries you've never heard of. The term most often refers to technology that helps companies comply with government regulations. In 2028, businesses are projected to spend $208 billion on RegTech, according to Juniper Research. That's up from $30 billion in 2020.
	Asymmetric fire-retardant electrolytes could ensure safety and stability in lithium metal batteries New research published in Energy Material Advances holds significant implications for the future of high-energy-density batteries.
	Researchers take next step toward better performing batteries using less critical raw materials Marnix Wagemaker and Alexandros Vasileiadis in collaboration with researchers from the Chinese Academy of Sciences have published a paper in Nature Sustainability on fast-charging sodium-ion batteries and improvements made to the negative electrode. These can be made from organic materials. This reduces the dependence on rare materials that do not come from Europe.
	Studying flight paths and neighborhoods could lead to more considerate aviation When aerospace engineer Matthew Clarke overlayed flight paths in urban environments over maps showing social stratification, he noticed something significant. The flights went directly overhead low-income neighborhoods.
	Orbital angular momentum-mediated machine learning for high-accuracy mode-feature encoding As a derivative product of artificial neural networks, ChatGPT became extremely popular in 2023, breaking the shortest time record for technology product users to exceed 100 million. It is a large-scale language model based on machine learning (deep learning), in which learning of language rules from massive input texts plays an important role.
	Cobalt-free electrodes achieved with nickel ions Many electric vehicles are powered by lithium-ion batteries that rely on cobalt—a scarce, expensive metal with high environmental and social costs. A team of researchers from Japanese and French universities has now developed a practical nickel-based electrode material that opens new avenues to cobalt-free batteries for electric vehicles.
	Made-in-China airliner shown overseas at Singapore Airshow China's first domestically produced passenger jet will be presented to potential buyers in an international debut at Asia's biggest airshow, which opens in Singapore on Tuesday.
	Capital One to buy Discover for $35.3 bn US banking giant Capital One announced Monday it will acquire financial services company Discover in a $35.3 billion all-stock deal combining two of America's major credit card firms.
	Singapore Airshow features aerial displays and the international debut of China's C919 The Singapore Airshow—Asia's largest—kicked off Tuesday with an array of aerial displays including some by China's COMAC C919 narrow-body airliner.
	Walmart to acquire smart TV maker Vizio for $2.3 billion in bid to boost its advertising business Walmart is buying the smart TV maker Vizio for $2.3 billion as it attempts to expand its rapidly growing advertising business to compete with Amazon.
	Stuck in cyberattack nightmare? Call the negotiators Criminals have overtaken your computer network, they are threatening to leak your most sensitive secrets and your share price is tumbling. It's time to call in the negotiators.
	Global operation smashes 'most harmful cyber crime group' An international operation led by UK and US law enforcement has severely disrupted "the world's most harmful cybercrime group", the Russian-linked ransomware specialist LockBit, officials announced Tuesday.
	Energy Strategy 2050: The potential of millions of Swiss rooftops Five million rooftops in Switzerland—more than half of the nationwide total—are suitable for generating power. A review of two solar photovoltaic development strategies has shown that combining the two approaches could cause over two-thirds of Swiss towns and cities to become energy self-sufficient.
