Technology news

	A simple technique to defend ChatGPT against jailbreak attacks Large language models (LLMs), deep learning-based models trained to generate, summarize, translate and process written texts, have gained significant attention after the release of Open AI's conversational platform ChatGPT. While ChatGPT and similar platforms are now widely used for a wide range of applications, they could be vulnerable to a specific type of cyberattack producing biased, unreliable or even offensive responses.
	A hybrid control architecture that combines advantages of current quadruped robot controls A team of robotics engineers at Robotic Systems Lab, in Switzerland, has developed a hybrid control architecture that combines the advantages of current quadruped robot control systems to give four-legged robots better walking capabilities on rough terrain.
	Robots that can autonomously build structures out of lattice blocks A combined team of engineers from NASA Ames Research Center and KBR has designed and built a robot system that can autonomously build structures using specially designed lattice blocks. In their paper published in the journal Science Robotics, the group describes the robots and the lattice blocks they use to build structures and how they whole system works.
	Machine learning method speeds up discovery of green energy materials Researchers at Kyushu University, in collaboration with Osaka University and the Fine Ceramics Center, have developed a framework that uses machine learning to speed up the discovery of materials for green energy technology.
	Self-powered sensor automatically harvests magnetic energy MIT researchers have developed a battery-free, self-powered sensor that can harvest energy from its environment.
	New, portable antenna could help restore communication after disasters Researchers from Stanford and the American University of Beirut have developed a lightweight, portable antenna that can communicate with satellites and devices on the ground, making it easier to coordinate rescue and relief efforts in disaster-prone areas.
	Next-generation batteries could go organic, cobalt-free for long-lasting power In the switch to "greener" energy sources, the demand for rechargeable lithium-ion batteries is surging. However, their cathodes typically contain cobalt—a metal whose extraction has high environmental and societal costs. Now, researchers in ACS Central Science report evaluating an earth-abundant, carbon-based cathode material that could replace cobalt and other scarce and toxic metals without sacrificing lithium-ion battery performance.
	Mini-robots modeled on insects may be smallest, lightest, fastest ever developed Two insect-like robots, a mini-bug and a water strider, developed at Washington State University, are the smallest, lightest and fastest fully functional micro-robots ever known to be created.
	Apple loosens grip on iPhone apps—with a catch After a years-long legal battle, Apple says it will begin allowing iPhone app developers to use alternative payment systems—but they will still have to pay fees and meet various conditions.
	TSMC to launch chipmaking plant in Japan, but US plant to face delays Taiwan's TSMC will open its latest chipmaking foundry on Japan's Kyushu island on February 24, but a plant in the United States will face further delays, the company said Thursday.
	Tiny AI-based bio-loggers revealing the interesting bits of a bird's day Have you ever wondered what wildlife animals do all day? Documentaries offer a glimpse into their lives, but animals under the watchful eye do not do anything interesting. The true essence of their behaviors remains elusive. Now, researchers from Japan have developed a camera that allows us to capture these behaviors.
	Sheryl Sandberg, who helped to turn Facebook into digital advertising empire, to leave company board Sheryl Sandberg, who helped to transform Facebook from a tech startup into a digital advertising empire, will step down from the board of Meta, Facebook's parent company.
	Google CEO warns of more layoffs Google CEO Sundar Pichai has warned employees that more layoffs are in store at the search engine giant as it focused on new priorities, including artificial intelligence.
	Research team designs privacy-protecting algorithm for better wireless communication In today's increasingly interconnected world, high-quality communication has become more vital than ever. Accurately estimating the dynamic status of communication channels is a key factor in achieving this. Recently, a joint research team designed a new algorithm that offers high-level estimation accuracy and privacy protection with low computational and communication costs. This research was published in Intelligent Computing.
	Reining in AI means figuring out which regulation options are feasible, both technically and economically Concern about generative artificial intelligence technologies seems to be growing almost as fast as the spread of the technologies themselves. These worries are driven by unease about the possible spread of disinformation at a scale never seen before, and fears of loss of employment, loss of control over creative works, and, more futuristically, AI becoming so powerful that it causes extinction of the human species.
	Why electric trucks are our best bet to cut road transport emissions Transport is likely the hardest economic sector to decarbonize. And road vehicles produce the most greenhouse gas emissions of the Australian transport sector—85% of its total. Freight trucks account for only 8% of travel on our roads but 27% of transport emissions.
	Australia plans to regulate 'high-risk' AI. Here's how to do that successfully This week, federal Minister for Industry and Science Ed Husic announced the Australian government's response to the Safe and Responsible AI in Australia consultation.
	Novel frequency-adaptive methods enhance remote sensing image processing Researchers led by Prof. Xie Chengjun and Associate Prof. Zhang Jie at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have developed a novel deep learning-based method for satellite imagery.
	Electric cars jolt Europe sales for 2023 New car sales in Europe rebounded by 13.9 percent in 2023 as electric vehicles overtook diesel for the first time, an industry group said on Thursday.
	Quantum computing to spark 'cybersecurity Armageddon,' IBM says Governments and businesses are not prepared for the havoc quantum computers will sow in cybersecurity by the end of the decade, according to an International Business Machines Corp. executive.
	Meta joins rivals in pursuit of human-level AI Meta CEO Mark Zuckerberg on Thursday said his company is joining the pursuit of creating super artificial intelligence, putting it in a race with Microsoft-backed OpenAI and Google.
	New tool analyzes news media sentiment regarding shipping industry A study in the International Journal of Shipping and Transport Logistics has introduced a new Shipping Industry Risk Sentiment Index (SRSI). This tool has been designed to analyze sentiment in the news media concerning South Korea's shipping industry. The SRSI utilizes an innovative method involving text analysis of news articles from Korean newspapers, focusing on terms related to the six C's of credit—character, capacity, capital, company, conditions, and collateral.
	US officials say 40 Boeing jets have been inspected as investigations continue into midair blowout Federal officials have briefed a congressional committee on their investigations into a jetliner that lost a panel of its fuselage in midflight this month and revealed that airlines have inspected 40 identical Boeing planes.
