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 / Microbial clocks can accurately estimate time since death across different climates
New research reveals that microbial clocks—forensic tools that track the succession and development of bacteria and fungi involved in decomposition after death—are highly accurate for estimating time since death, or postmortem ...
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 / Krypton gas emerges as a new ingredient for quantum computing
To commercialize quantum computing, manufacturers need high-quality superconducting materials for microchips, but they also require a reliable, sustainable nanofabrication process. Tantalum is a corrosion-resistant metal ...
Medical Xpress / New metric reveals how inequality can spark epidemics despite low overall risk
Influenza spreads in a crowded barracks or prison. Ebola proliferates when per capita hospital beds plummet below typical levels in developed countries. Bedside discrimination leads some patients to die and others to survive.
Medical Xpress / How highly aggressive colon cancer evades the immune system
Researchers from the German Cancer Research Center (DKFZ) and the HI-STEM Stem Cell Institute have identified a previously unknown mechanism by which a particularly aggressive form of colon cancer evades the immune system.
Phys.org / Interstellar travel IV: Solar, magnetic, & directed-energy sails
Welcome back to our series on interstellar travel! In our first installment, we examined attempts to realize nuclear propulsion and how the technology could be used to reach the nearest star. In our second, we examined how ...
Phys.org / Interacting with AI can make people act more like robots
As AI continues to develop at a rapid pace, social robots powered by AI are becoming more commonplace in customer service settings such as retail, hospitality, tourism and health care. But as these robots become smarter and ...
Medical Xpress / Prostate cancer hijacks amino acid metabolism to signal hormone therapy resistance
Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.
Phys.org / As Europe's rivers recede, shippers scramble to limit damage
Exceptionally low river levels in a Europe hit hard by drought and record heat have plunged transporters into turmoil this summer, driving up costs that everyday consumers could end up bearing.
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 / Rings forged from meteorites may have been fashionable among ancient Greek elites
Meteorites provided a rare but ready source of iron for ancient Bronze Age cultures before smelting became common. A new study, published in the Journal of Archaeological Science, sheds light on how the ancient Minoan and ...
