Technology news

	DeepMind develops SAFE, an AI-based app that can fact-check LLMs A team of artificial intelligence specialists at Google's DeepMind has developed an AI-based system called SAFE that can be used to fact check the results of LLMs such as ChatGPT. The group has published a paper describing the new AI system and how well it performed on the arXiv preprint server.
	Unleashing disordered rocksalt oxides as cathodes for rechargeable magnesium batteries Researchers at Tohoku University have made a advancement in battery technology by developing a novel cathode material for rechargeable magnesium batteries (RMBs) that enables efficient charging and discharging even at low temperatures. This innovative material, leveraging an enhanced rock-salt structure, promises to usher in a new era of energy storage solutions that are more affordable, safer, and higher in capacity.
	Universal brain-computer interface lets people play games with just their thoughts Imagine playing a racing game like Mario Kart, using only your brain to execute the complex series of turns in a lap.
	Next-generation AI semiconductor devices mimic the human brain A research team led by Prof. Kwon Hyuk-jun of the DGIST Department of Electrical Engineering and Computer Science has developed a next-generation AI semiconductor technology that mimics the human brain's efficiency in AI and neuromorphic systems.
	Increasing the efficiency of eco-friendly solar cells by converting wind energy into high-voltage electricity A research team led by Professor Lee Ju-hyuck of DGIST in the Department of Energy Science & Engineering has successfully developed an energy harvesting device that enhances solar energy efficiency by removing and preventing surface contamination on solar cells.
	A first-ever complete map for elastic strain engineering Without a map, it can be just about impossible to know not just where you are, but where you're going, and that's especially true when it comes to materials properties.
	Chinese tech giant Huawei says profits more than doubled in 2023 Chinese tech giant Huawei said on Friday its profits more than doubled in 2023, as it ramps up efforts to bounce back in a year that saw the company apparently defy US sanctions with the release of a high-end smartphone.
	Researchers improve reversibility, specific capacity of iron-based phosphate cathodes for Na-ion batteries Thanks to the low cost of raw materials and long lifespan rendered by their stable structure, iron-based phosphate cathodes are regarded as one of the most promising cathodes for Na-ion batteries (NIBs).
	Can Boeing be trusted again? What steps can the biggest name in aviation take to repair its reputation? Every year, billions of people board planes that are built by one of two manufacturers—Boeing, an American manufacturer, and Airbus, a European corporation.
	Enhancing defect detection performance in smart factories Prof. Sang Hyun Park's research team in the Department of Robotics and Mechatronics Engineering at DGIST has developed a logical anomaly detection technology in collaboration with a team from Stanford University. This technology is expected to significantly improve defect detection performance in smart factories by leveraging AI to identify logical anomalies in industrial images accurately.
	Green truckin': US finalizes new heavy-vehicle pollution standards Following last week's crackdown on car emissions, President Joe Biden's administration on Friday unveiled finalized pollution standards for trucks, placing vehicle tailpipes at the forefront of his climate crisis agenda.
	Research team develops next-generation semiconductor memory that operates in extreme environments Researchers have developed a new manufacturing technology that enables the production of high-quality oxide films and effective patterning at low temperatures and manufactured non-volatile resistive random access memory. It is expected to be used in next-generation computing systems by overcoming the shortcomings of existing manufacturing technologies and developing memories with excellent durability.
	Brain-inspired chaotic spiking backpropagation Since it was discovered in the 1980s that learning in the rabbit brain utilizes chaos, this nonlinear and initially value-sensitive dynamical behavior has been increasingly recognized as integral to brain learning.
	Synergically improved energy storage performance and stability in tri-layer films with crystalline sandwich structures As a green, sustainable, and competitive technology relative to batteries and electrochemical capacitors and featuring a high charge storage capability, the dielectric capacitors excel in low cost, long cycle-life, and a broad operating temperature range, as well as environmental friendliness, high security, and good reliability.
	Solution to energy storage may be beneath your feet Anyone who has ever hot-footed it barefoot across the beach on a sunny day walks away with a greater understanding of just how much heat sand can retain. That ability is expected to play a vital role in the future, as technology involving heated sand becomes part of the answer to energy storage needs.
	DeSantis' office quietly backed Florida ban on wind energy Gov. Ron DeSantis' office quietly helped write a bill to curtail wind energy in the state of Florida, email records provided to the Tampa Bay Times show.
	European regulators are cracking down on Alphabet, Apple and Meta. How will that impact their work? U.S. officials could learn a thing for two from their friends in Europe as they assume a bigger role in taking on Big Tech, says a Northeastern University antitrust expert.
	Biofuels could help island nations survive a global catastrophe, study suggests A major global catastrophe could disrupt trade in liquid fuels used to sustain industrial agriculture, impacting the food supply of island nations like New Zealand that depend on oil imports.
	How AI discriminates and what that means for your Google habit Safiya Umoja Noble swears she is not a Luddite. But she does think we could all learn a thing or two from the machine-bashing textile craftsmen in 19th-century Britain whose name is now synonymous with technological skepticism.
	A single-crystal-like mesoporous material for high-performance lithium storage In lithium-ion storage, microstructured single crystal electrode materials show great advantages for ionic conductivity because of removing grain boundaries inside the materials but usually trade off the diffusion distance of Li ions in the microsized particle, consequently reducing the rate capability and cycle stability.
	Similar to traditional semiconductors, lead halide perovskites achieve effective electrical doping For traditional semiconductor materials and devices, controlling the distribution of electrical doping to build an internal electric field is a common method to enhance carrier extraction efficiency. Therefore, electrical doping is of great significance for the construction of high-performance devices.
	A biased edge enhancement method for truss-based community search Community Search, which targets a cohesive and meaningful community containing the query node, has drawn intense research interest and had extensive applications in various real-world networks recently.
