A bird banking in a crosswind doesn’t rely on spinning blades. Its wings flex, twist and respond instantly to its environment. Engineers at Rutgers University have taken a major step toward building bird-like drones that move the same way, flapping their wings like real birds, using electricity-driven materials instead of conventional electromagnetic motors to power them.A bird banking in a crosswind doesn’t rely on spinning blades.

Researchers have identified key components in large language models (LLMs) that play a critical role in ensuring these AI systems provide safe responses to user queries. The researchers used these insights to develop and demonstrate AI training techniques that improve LLM safety while minimizing the “alignment tax,” meaning the AI becomes safer without significantly affecting performance.Researchers have identified key components in large language models (LLMs) that play a critical role in ensuring these AI systems provide safe responses to user queries.

A collaborative research group has developed a bio-inspired robotic system based on insect behavior which can locate odor sources both indoors and outdoors with consistent accuracy, even if one of its two sensors fails. The team includes Assistant Professor Shigaki Shunsuke of the National Institute of Informatics (NII), Professor Kurabayashi Daisuke of the School of Engineering at Science Tokyo, and Associate Professor Owaki Dai of the Graduate School of Engineering at Tohoku University.A collaborative research group has developed a bio-inspired robotic system based on insect behavior which can locate odor sources both indoors and outdoors with consistent accuracy, even if one of its two sensors fails.

Scientists at the University of Sharjah have developed a new machine learning model capable of predicting whether a driver is likely to be involved in an accident before getting behind the wheel. Road accidents are frequently linked to human error, yet traditional driver screening methods, particularly in the taxi and commercial transport sectors, tend to rely heavily on experience and background checks. According to the researchers, these criteria often fall short of predicting who may pose a higher risk on the road.Scientists at the University of Sharjah have developed a new machine learning model capable of predicting whether a driver is likely to be involved in an accident before getting behind the wheel.

Power usage by AI and data center systems in the U.S. is extraordinary by any measure. The International Energy Agency estimates U.S. AI and data centers used about 415 terawatt hours of power in 2024—more than 10% of that year’s nationwide energy output—and it’s expected to double by 2030.Power usage by AI and data center systems in the U.S. is extraordinary by any measure.

Googling isn’t quite what it used to be. Now, when typing something into Google’s search engine, the first response flashing to life on your screen is not the top-ranked search result but an “AI Overview.” When asked why (using Google’s search engine), the AI Overview replied: “… to provide users with quick, synthesized answers to complex or multi-step questions, enhancing efficiency and user experience. The goal is to save users time by presenting relevant information from multiple sources in one place, reducing the need to click through multiple links.”Googling isn’t quite what it used to be.

Scientists have developed a network of mechanical motors that mimic the molecular machinery underpinning human muscle contraction. The University of Bristol-led findings, published in the Journal of the Royal Society Interface this week, could open new possibilities for artificial muscles in robotics.Scientists have developed a network of mechanical motors that mimic the molecular machinery underpinning human muscle contraction.

Large language models (LLMs), artificial intelligence systems that can process and generate texts in different languages, are now used daily by many people worldwide. As these models can rapidly source information and create convincing content for specific purposes, they are now also used in some professional settings or for gathering legal, medical, or financial information.Large language models (LLMs), artificial intelligence systems that can process and generate texts in different languages, are now used daily by many people worldwide.
