Technology news

	A dexterous four-legged robot that can walk and handle objects simultaneously Four-legged robots, also known as quadrupedal robots, have advantageous characteristics, including the ability to rapidly walk on challenging terrains and keep a low center of gravity. Some four-legged robots can also manipulate objects in their surroundings, yet this is typically achieved using arm-like structures mounted at the top of the robots, rather than the limbs they use to walk.
	Climate change will increase value of residential rooftop solar panels across US, study finds Climate change will increase the future value of residential rooftop solar panels across the United States by up to 19% by the end of the century, according to a new University of Michigan-led study.
	Harnessing solar energy for high-efficiency NH₃ production A technology that harnesses solar energy to produce high-efficiency ammonia (NH3) has been unveiled by a research team affiliated with UNIST.
	Versatile fibers offer improved energy storage capacity for wearable devices The latest wearable devices, such as Samsung's Galaxy Ring and Apple's Vision Pro, are taking health care a step further and even enabling people to work virtually. Given the characteristics of wearable devices that require them to be small and lightweight, there is an inevitable limitation on battery capacity, still presenting a technical barrier to incorporating a variety of functions. In order for wearable devices to fully realize their potential, it is necessary to develop a lighter and 'more from less' energy storage method.
	To build a better AI helper, start by modeling the irrational behavior of humans To build AI systems that can collaborate effectively with humans, it helps to have a good model of human behavior to start with. But humans tend to behave suboptimally when making decisions.
	Microsoft's AI app VASA-1 makes photographs talk and sing with believable facial expressions A team of AI researchers at Microsoft Research Asia has developed an AI application that converts a still image of a person and an audio track into an animation that accurately portrays the individual speaking or singing the audio track with appropriate facial expressions.
	A flexible and efficient DC power converter for sustainable-energy microgrids A new DC-DC power converter is superior to previous designs and paves the way for more efficient, reliable and sustainable energy storage and conversion solutions. The Kobe University development can efficiently interface with a wide range of energy sources while enhancing system stability and simplicity at an unprecedented efficiency.
	Silent flight edges closer to take off, according to new research The mystery of how futuristic aircraft-embedded engines, featuring an energy-conserving arrangement, make noise has been solved by researchers at the University of Bristol.
	Greater access to clean water, thanks to a better membrane Water scarcity around the world is a bigger problem than ever, and desalination is critical to solving it. The best available technologies for separating salt from seawater, though, are costly and require a great deal of maintenance.
	Researchers develop sodium battery capable of rapid charging in just a few seconds Sodium (Na), which is over 500 times more abundant than lithium (Li), has recently garnered significant attention for its potential in sodium-ion battery technologies. However, existing sodium-ion batteries face fundamental limitations, including lower power output, constrained storage properties, and longer charging times, necessitating the development of next-generation energy storage materials.
	Apple pulls WhatsApp and Threads from App Store on Beijing's orders Apple said it had removed Meta's WhatsApp messaging app and its Threads social media app from the App Store in China to comply with orders from Chinese authorities.
	Google is combining its Android software and Pixel hardware divisions to more broadly integrate AI Google will combine the software division responsible for Android mobile software and the Chrome browser with the hardware division known for Pixel smartphones and Fitbit wearables, the company said Thursday. It's part of a broader plan to integrate artificial intelligence more widely throughout the company.
	Netflix now has nearly 270 million subscribers after another strong showing to begin 2024 Netflix gained another 9.3 million subscribers to start the year while its profit soared with the help of a still-emerging expansion into advertising, but caught investors off guard with a change that will make it more difficult to track the video streaming service's future growth.
	Bitcoin's next 'halving' is right around the corner. Here's what you need to know Sometime in the next few days or even hours, the "miners" who chisel bitcoins out of complex mathematics are going to take a 50% pay cut—effectively slicing new production of the world's largest cryptocurrency in half.
	Japan doctors sue Google Maps over 'punching bag' reviews Around 60 doctors in Japan have accused Google Maps of ignoring vitriolic reviews of their clinics in a class-action lawsuit touted as the first of its kind.
	Quarter of UK 5 to 7-year-olds have smartphone: Study Around a quarter of British children aged between five and seven-years-old now have a smart phone, a study by the UK communications regulator said on Friday.
	Houses made of waste changing lives in South America Homes made of discarded plastic bottles, construction waste and old tires are being built across Latin America as new technologies help turn municipal waste into sustainable bricks and tiles.
	Are tomorrow's engineers ready to face AI's ethical challenges? A chatbot turns hostile. A test version of a Roomba vacuum collects images of users in private situations. A Black woman is falsely identified as a suspect on the basis of facial recognition software, which tends to be less accurate at identifying women and people of color.
	Understanding AI outputs: Study shows pro-western cultural bias in the way AI decisions are explained Humans are increasingly using artificial intelligence (AI) to inform decisions about our lives. AI is, for instance, helping to make hiring choices and offer medical diagnoses.
	South Africa's electricity crisis: A series of failures over 30 years have left a dim legacy In 1994, apartheid ended and the African National Congress (ANC) won South Africa's first ever democratic elections, promising "Electricity for All" as part of its Reconstruction and Development Program.
	Crime detection and crime hot spot prediction using a deep learning model Crime is an age-old and never-ending problem for societies worldwide and crime detection and crime fighting have always chased after the criminals who often stay one step ahead.
	Study unlocks opportunities to bridge the US wind energy workforce gap U.S. land-based and offshore wind energy markets are expected to grow significantly over the next few decades. With this growth, the demand for properly trained wind energy workers will also increase to meet national deployment targets.
	New flight procedures to reduce noise from aircraft departing and arriving at Boston Logan Airport If you're a resident of Hull, Lynn, Salem, or other Massachusetts towns currently exposed to noise from aircraft approaching Boston Logan Airport, you may notice the skies getting a little quieter this year.
	The biggest barrier to a vibrant second-hand electric vehicle market? Price News policies and broader subsidies are needed to help lower-income buyers afford used electric vehicles, according to a Rutgers study.
	Olympic organizers unveil strategy for using artificial intelligence in sports Olympic organizers unveiled their strategy Friday to use artificial intelligence in sports, joining the global rush to capitalize on the rapidly advancing technology.
	Tesla to recall Cybertruck over acceleration defect Tesla is recalling 3,878 Cybertruck vehicles because of a defect that can cause unintentional vehicle acceleration, increasing crash risk, according to a US notice posted this week.

	Linkable and traceable anonymous authentication with fine-grained access control Anonymous authentication plays a crucial role in privacy-focused applications, and it is used for authenticating a user's identity in a privacy-preserving way. If enough privacy is provided, malicious users may misuse privacy. Accountability is necessary to avoid abusing anonymity. Previous anonymous authentication schemes can not hold the basic requirements of public linking and tracing while further ensuring access control simultaneously.
	Walmart, M.D.: Why the world's largest retailer wants to be America's doctor Walmart, the largest U.S. employer with a workforce of 1.6 million, is slowly building a network of in-store clinics, believing it has a place in America's health care system.
