Researchers at Emory University have found how a simple adjustment of solution heating time raises perovskite LED efficiency to almost 40%.
AI agent sold a keyboard and gave the owner's address to a late-night buyer
A Canadian blogger let an AI agent sell a keyboard on Facebook Marketplace. It agreed a price on its own, gave a stranger his home address and sent the message "I'm here!" while the owner was asleep.
AI chatbot can both soothe and trap users in anxious thoughts, researcher warns
Australian researcher Warren Mansell warns that the same AI conversational partner can help a person understand their feelings or reinforce harmful beliefs and create emotional dependence.
Microsoft exits deal on UK AI data center in Loughton
The US corporation has pulled out of leasing capacity at a planned data center in Loughton, which had been linked to plans to make Britain an AI leader. The reason is difficulties connecting to the power grid.
Korean scientists create low-cost electrode for hydrogen production
Researchers from the Korea Institute of Energy Research have developed nickel- and cobalt-based electrodes that match platinum in efficiency but cost far less, potentially lowering the cost of green hydrogen.
Tech-savvy bank customers more often risk money online, researchers find
A survey of 772 e-banking users in India found that good knowledge of cyber threats does not always lead to safe behavior. It depends on attitudes to security, memory and technical confidence.

Researchers at Cornell University have developed a chip that creates microbubbles on demand and steers fluid flows with ultrasound, a technology that could aid targeted drug delivery.
Fingerprint authentication without stored data: ultrasound does the job
Researchers at POSTECH have created a fingerprint recognition system that does not store biometric data digitally but uses the physical properties of ultrasound.
Encrypted traffic attack threatens water treatment
Researchers at the University of British Columbia showed how the rhythm of encrypted traffic can be used to identify critical commands and selectively block them without reading their contents.
Korean scientists find way to sharply boost efficiency of hydrogen fuel cells
Researchers at Sungkyunkwan University have developed a nanometer-scale coating that improves contact between electrode and electrolyte, raising the power and durability of protonic ceramic electrochemical cells.
AI assistants can secretly steer you toward a bad choice - and you may even thank them
An experiment with 233 participants showed that when an AI adviser has a hidden agenda, people are five to eight times more likely to choose the disadvantageous option, yet still rate the assistant as "very helpful."
Brain organoids recognize Braille letters: a step toward biohybrid computing
British scientists tested whether miniature brain models can receive and transmit signals. Three organoids together recognized tactile letters more accurately than one, but learning has not yet been tested.
AI to help search for missing children in Mexico
Mexican universities are creating artificial intelligence-based tools to help families search for missing children.
Google makes AI search links more visible as publishers lose 40% of traffic
Google says links to sites and articles will be more prominent and appear higher in AI-generated search results, amid concern from brands and news publishers over falling traffic.
Meta releases "open" AI model it says beats Chinese rivals
Meta has unveiled Muse Spark Open, an open-weight AI model it says rivals or surpasses leading Chinese developers' products, days after announcing its closed Wonder and Wonder Full models.
AI fails Turing test: 97% of participants saw through GPT-4
A new study found that modern language models do not pass the classic Turing test when it is conducted according to the original method rather than simplified rules.
Crank the handle and learn your blood type: Taiwanese scientists devise pocket test without electricity
A hand-powered plastic chip identifies blood type and red cell level in about a minute, which could save lives in an ambulance or disaster zone.
AI agents learned to predict consequences of edits to their own code
Researchers from the University of Virginia, Microsoft Research and Tsinghua University have created a forecasting program that helps AI agents assess the consequences of edits to their code before testing.
Flexible film cools electronics using moisture from the air
Scientists from South Korea have created a flexible material that collects moisture from the air and lowers the temperature of operating devices without pumps, fans or energy costs.
From old batteries to twice the lifespan: recycling method shows surprising results
Researchers at WPI turned mixed battery waste into cathode and anode materials, and cells built from them lasted nearly twice as long as commercial counterparts.
