Tech Xplore / 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 ...
Tech Xplore / 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 ...
Tech Xplore / Organic solar cells degrade quickly, but a solid additive could help them last longer
Solar power continues to grow—accounting for most new capacity added to U.S. electric grids in 2024—but the mid-1950s technology most often used to capture the sun's energy comes with environmental costs.
Tech Xplore / 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 ...
Tech Xplore / AI robot vehicles learn to team up and extinguish fires in early trial
Fighting fires could be done remotely without the need to place firefighting crews directly in potentially dangerous situations by using collaborative teams of artificial intelligence-powered robots with extinguishing equipment ...
Tech Xplore / 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 ...
Tech Xplore / 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 ...
Tech Xplore / New world for users and brands as ads hit AI chatbots
The introduction of advertisements and sponsored content in chatbots has spawned privacy concerns for AI users as brands scramble to stay relevant in a fast-changing online environment.
Tech Xplore / 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) ...
Tech Xplore / Cybersecurity spending may pay off: Study links readiness to stronger returns
The infamous Target data breach during the 2013 holiday shopping season, which cost the company more than $200 million in damages, has since been hailed as a landmark case in cybersecurity. Exposure to these threats has only ...
Tech Xplore / Feeling 'AI anxiety'? Here are the risks people fear most
A patient said to me the other day, half-smiling but clearly unsettled: "I think I've got anxiety about AI." They weren't having a panic attack or describing clinical anxiety. What they were expressing was a persistent sense ...
Tech Xplore / Organic molecule stores solar energy for years, then releases it as heat on demand
When the sun goes down, solar panels stop working. This is the fundamental hurdle of renewable energy: how to save the sun's power for a rainy day—or a cold night. Chemists at UC Santa Barbara have developed a solution ...
