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 ...

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 ...

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 ...

Lithium-metal batteries (LMBs) are rechargeable batteries that contain an anode (i.e., the electrode through which current flows and a loss of electrons occurs) made of lithium metal. Compared to conventional lithium-ion ...

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 ...

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 ...

When generative AI systems produce false information, this is often framed as AI "hallucinating at us"—generating errors that we might mistakenly accept as true. But a new study argues we should pay attention to a more ...

Generative artificial intelligence systems often work in agreement, complimenting the user in its response. But human interactions aren't typically built on flattery. To help strengthen these conversations, researchers in ...

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 ...

When AI-powered prosthetic arms that move autonomously become widespread, understanding how people feel about them and accept them will be crucial. In a study appearing in Scientific Reports, scientists used virtual reality ...

Metal alloys crack and fail through a mechanism called "fatigue" when repeatedly loaded and strained. While it is well known how to design alloys to withstand static loads and pressures, it is very difficult to design resistance ...

The approximately 5 billion people who use the internet daily leave traces of their activity behind. Companies use these data to learn user interests, purchase history, and other browsing habits, and benefit through sales, ...
