Tech Xplore / OpenAI pulls the plug on Sora, the viral AI video app that sparked deepfake concerns
OpenAI is shutting down its social media app Sora, which went viral last fall as a place to share short-form videos generated by artificial intelligence but also raised alarms in Hollywood and elsewhere.
Tech Xplore / AI making cyber attacks costlier and more effective: Munich Re
Artificial intelligence is making cyberattacks increasingly sophisticated and costlier for businesses, reinsurer Munich Re said Wednesday, warning of methods ranging from highly personalized phishing emails to computer-generated, ...
Tech Xplore / New bifacial solar cells yield efficiencies above 32%
Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries worldwide. Over the past few years, energy engineers have been exploring alternative designs that could further boost ...
Tech Xplore / Fragmented phone use—not total screen time—is the main driver of information overload, study finds
Amid hot discussion on screen time, social media use and the impact of digital devices on our well-being, a seven-month study from Aalto University in Finland sheds new light on what overwhelms users the most—and the results ...
Tech Xplore / LLMs and creativity: AI responses show less variety than human ones
Can using a large language model (LLM) make a person more creative? Prior work has shown that using LLMs can make creative outputs more homogeneous, but this homogenization could stem from the specific LLM used or from widespread ...
Tech Xplore / Stamping high-res imagery onto everyday items to 'reprogram' their appearance
Imagine a world where you could change the designs you see on bags, shirts, and walls whenever you want. Typical clothes would become customizable fashion pieces, while your humble abode could turn into a smart home. That's ...
Tech Xplore / Sensor chips help identify deepfakes by adding cryptographic signatures to camera data
AI-generated images and videos pose a threat to democratic processes and undermine trust within society. Researchers at ETH Zurich have now developed chip technology that enables verification of the authenticity of sensor ...
Tech Xplore / Platinum-free fuel cells get a boost thanks to carbon-coated nickel catalyst
A high acid environment is great for a snappy hydrogen oxidation reaction—the reaction at the heart of a clean-energy fuel cell. The problem is the only catalysts that won't dissolve in the high acid of traditional fuel cells ...
Tech Xplore / Study finds AI privacy leaks hinge on a few high-impact neural network weights
Researchers have discovered that some of the elements of AI neural networks that contribute to data-privacy vulnerabilities are also key to the performance of those models. The researchers used this new information to develop ...
Tech Xplore / Thousands of pico-satellites may transform how phones connect to space
Swarms of pico-satellites could work together as a single large antenna for direct-to-smartphone communications, as reported by researchers from Japan. Instead of relying on a single large satellite with a phased-array antenna, ...
Tech Xplore / New detector chip compresses X-ray data 100- to 200-fold in real time
Every second, scientific experiments produce a flood of data—so much that transmitting and analyzing it can slow down even the most advanced research. To help scientists better manage this data deluge, researchers at the ...
Tech Xplore / How autonomous vehicles could change morning commutes
Autonomous vehicles (AVs), which already operate on the roads of several major U.S. cities and in countries worldwide, are expected to play a large role in shaping the future of cities. In a new study, researchers have investigated ...
