Technology news

	A framework to improve air-ground robot navigation in complex occlusion-prone environments Robotic systems have so far been primarily deployed in warehouses, airports, malls, offices, and other indoor environments, where they assist humans with basic manual tasks or answer simple queries. In the future, however, they could also be deployed in unknown and unmapped environments, where obstacles can easily occlude their sensors, increasing the risk of collisions.
	Chipless fiber for wireless visual-to-digital transmission senses interactions with the human body A team of materials scientists and engineers from Donghua University, in China, and the National University of Singapore, has developed a type of fiber that does not rely on chips or batteries to convert visual signals to digital transmissions as it interacts with the human body.
	Without community support, the green energy transition will fail: How to get communities on board Connecting cheap, clean energy from renewables comes with a hidden cost and challenge: building 5,000 kilometers of new transmission lines this decade, and another 5,000km after that. This sounds like a lot, but 5,000km is only around 10% of the existing grid network, and unlocks more than 32 gigawatts of new clean energy capacity by 2030.
	Advances in understanding COPV structural life The Structures Technical Discipline Team (TDT) was involved in numerous investigations this past year, but composites, fracture mechanics, and pressure vessels dominate the list. All three of these specialties are important to composite overwrapped pressure vessels (COPV).
	NASA noise prediction tool supports users in air taxi industry Several air taxi companies are using a NASA-developed computer software tool to predict aircraft noise and aerodynamic performance. This tool allows manufacturers working in fields related to NASA's Advanced Air Mobility mission to see early in the aircraft development process how design elements like propellors or wings would perform. This saves the industry time and money when making potential design modifications.
	Manual transcription still beats AI: A comparative study on transcription services A research team from the Empirical Research Support (ERS) at CISPA Helmholtz Center for Information Security has conducted a systematic comparison of the most popular transcription services. The comparison involved 11 providers of manual as well as AI-based transcriptions.
	Swiss energy study shows transformative potential of decentralization Researchers from EPFL and HES-SO Valais Wallis have published a study outlining a path to a more sustainable energy future for Switzerland. The study emphasizes the importance of local energy solutions, and the role of decentralized systems for community empowerment.
	Sanction the use of cyberweapons, not the weapons themselves, concludes expert review A recent analysis by Helene Pleil, research associate at the Digital Society Institute (DSI) at ESMT Berlin, alongside colleagues from Technical University Darmstadt, outlines that rapid technological progress, a lack of political will and uniform definitions, as well as the dual use of cyber tools, are the main challenges facing effective cyber arms control which is vital for foreign and security policy. As cyberspace is increasingly used in conflicts, cyber arms control needs to be addressed as well.
	Texas can lead the new hydrogen economy, study finds A new study highlights the potential for Texas to become a global leader in the development of a robust hydrogen economy.
	Researchers unveil time series deep learning technique for optimal performance in AI models A team of researchers has unveiled a time series machine learning technique designed to address data drift challenges. This innovative approach, led by Professor Sungil Kim and Professor Dongyoung Lim from the Department of Industrial Engineering and the Artificial Intelligence Graduate School at UNIST, effectively handles irregular sampling intervals and missing values in real-world time series data, offering a robust solution for ensuring optimal performance in artificial intelligence (AI) models.
	China's green-tech manufacturing powerhouse China has extended its manufacturing domination to clean energy industries in recent years, alongside a global push for climate change action, but that is starting to worry the United States, Europe and others.
	X gives free blue check to big follower accounts Users with big followings will receive a free subscription to X, formerly Twitter—and the platform's famous blue check, the company said in another policy U-turn.
	Zimbabwe launches new gold-backed currency Zimbabwe's central bank launched a new "structured currency" backed by gold on Friday, as it seeks to tackle sky-high inflation and stabilize the country's long-floundering economy.
	Apple lays off more than 600 workers in California in its first major round of post-pandemic cuts Apple is laying off more than 600 workers in California, marking the company's first big wave of post-pandemic job cuts amid a broader wave of tech industry consolidation.
	AI a 'game changer' but company execs not ready: survey A majority of corporate executives across leading economies believe artificial intelligence will be a "game changer" for their industry but admit their leadership teams lack the knowledge to understand AI's risks and rewards, a study showed Friday.
	Meta to start labeling AI-generated content in May Facebook and Instagram giant Meta on Friday said it will begin labeling AI-generated media beginning in May, as it tries to reassure users and governments over the risks of deepfakes.
	Microsoft says China using AI to sow division in US China is ramping up use of AI-generated content and fake social media accounts to inflame division in the United States and elsewhere, according to the latest report from Microsoft's threat center.
