Tech Xplore / More is different when AI agent populations work together, study suggests
New research published in Proceedings of the National Academy of Sciences suggests that when artificial intelligence (AI) agents interact in groups, their number is not merely a technical detail. It is a decisive factor in ...
Phys.org / Peru's highest mountain confirms tropics were a major methane source before the industrial era
A new analysis of ice cores collected from the Andes in Peru has produced the first global record of historical tropical methane, filling a critical gap in our understanding of the origins of Earth's greenhouse gases.
Phys.org / AI prompts offer a new tool for mapping how emotion concepts relate
How similar are "joy" and "surprise"? Conversely, how far apart are "joy" and "sadness"? We naturally organize words that express emotions—such as "happy," "afraid," and "angry"—according to similarities and differences in ...
Tech Xplore / How attackers persuade AI agents to break the rules
Today, most of us interact with AI assistants—reactive bots that wait for human instructions. Yet AI assistants are rapidly being replaced by agentic AI agents that can interact with external tools, browse the web, generate ...
Phys.org / Giant crocodylians dominated the food chain in Miocene South America, fossil evidence suggests
South America was a frightening place during the Miocene. More than 10 million years ago, a vast lake covered much of the continent, home to giant turtles and crocodylians.
Tech Xplore / Inexpensive reflective tiles pave the way for millimeter wave wireless communications
Unlike Wi-Fi or cellular signals, millimeter-wave wireless communication channels are unable to pass through walls, furniture or other objects. This reality is part of what is holding back the implementation of millimeter-wave ...
Tech Xplore / Hybrid magnetic device enables quantum-inspired secure communication at room temperature
MIT researchers have overcome a major challenge holding back the real-world deployment of microwave quantum technologies for advanced signal processing and secure communications.
Phys.org / Immune cells have a 'sense of touch,' scientists discover
Scientists have long believed that tissue-resident memory T cells—which remain in tissues after an infection has cleared and respond rapidly if the threat returns—are shaped primarily by biochemical signals. A McGill University–led ...
Phys.org / Largest catalog yet of how human cells read DNA shows how chemical marks alter genetic instructions
Every cell in the body contains essentially the same DNA, yet a brain cell behaves differently from a muscle cell or an immune cell. The difference lies largely in how each cell reads its genetic instructions.
Tech Xplore / Laser de-icing system helps nuclear power plants improve maintenance of a critical safety system
University of South Florida engineers have developed an innovative laser-based technology that is helping nuclear power plants solve a complex maintenance challenge affecting a critical reactor safety system. After four years ...
Medical Xpress / Drugs developed in China reaching international markets, research finds
China has become an increasingly important contributor to pharmaceutical development, but comparatively little attention has been paid to how successfully medicines developed in China have entered major international markets.
Phys.org / Spinach peptide discovery leads to citrus greening treatment
A citrus greening disease treatment rooted in more than a decade of research at Texas A&M AgriLife Research has reached a milestone on the path to commercial availability. The U.S. Environmental Protection Agency has granted ...
