Miniaturized radar chip developed for next-generation wireless networks

A miniaturized radar chip, developed by researchers at Science Tokyo, advances Integrated Sensing and Communication for Beyond 5G and 6G systems. Measuring just 0.24 mm2 and consuming only 9.8 mW, the compact, low-power device generates […]

Innovation

Woven nickel-titanium structures unlock new flexibility in 3D-printed shape-memory materials

At first glance, few materials would seem to have less in common than metals and textiles. And yet, by manufacturing nickel-titanium alloys as a highly deformable, interwoven material, more similar to fabric than a typical […]

Why ‘zero-knowledge encryption’ may not stop password theft if servers are hacked

People who regularly use online services have between 100 and 200 passwords. Very few can remember every single one. Password managers are therefore extremely helpful, allowing users to access all their passwords with just a […]

Energy-saving 5G features could cut carbon emissions across the UK economy

An optimal combination of energy-efficient 5G network features—including AI systems that let mobile mast and antenna base stations go into sleep mode when usage is low, and phones that avoid unnecessary background network checks—could help […]

Why AI may overcomplicate answers: Humans and LLMs show ‘addition bias,’ often choosing extra steps over subtraction

When making decisions and judgments, humans can fall into common “traps,” known as cognitive biases. A cognitive bias is essentially the tendency to process information in a specific way or follow a systematic pattern. One […]

LLMs violate boundaries during mental health dialogues, study finds

Artificial intelligence (AI) agents, particularly those based on large language models (LLMs) like the conversational platform ChatGPT, are now widely used daily by numerous people worldwide. LLMs can generate texts that are highly realistic, to […]

Innovation

Atom-thin ferroelectric transistor can store 3,024 polarization states

Over the past few decades, electronics engineers have been trying to develop new neuromorphic hardware, systems that mirror the organization of neurons in the human brain. These systems could run artificial intelligence (AI) models, particularly […]

Innovation

Midair haptics and levitation may get steadier with predictable ultrasonic airflow

Acoustic streaming generated by airborne ultrasonic phased arrays plays a critical role in the performance of advanced ultrasonic technologies, including midair haptic feedback, odor delivery, and acoustic levitation. Researchers at University of Tsukuba have developed […]

Rule-breaking discovery reveals new way to strengthen metal in extreme conditions

There’s a reason why blacksmiths fire metals before hammering them. Heat always softens metal, making it more malleable and easier to reshape. Or does it? In a surprising new study, Northwestern University engineers discovered that, […]

Innovation

Lithium alternatives? Calcium-ion batteries show strong 1,000-cycle performance in new test

Researchers at The Hong Kong University of Science and Technology (HKUST) have achieved a breakthrough in calcium-ion battery (CIB) technology, which could transform energy storage solutions in everyday life. Utilizing quasi-solid-state electrolytes (QSSEs), these innovative […]
