US prosecutors just charged a man with smuggling NVIDIA chips to China, and government officials are saying the company isn't doing all it could to stop the illegal activities, Bloomberg reported. Earlier this year, officials released a surveillance video showing someone using a red hair dryer to peel serial number stickers off NVIDIA server boxes in an effort to sneak AI chips to China. And yesterday, federal authorities arrested a man named Greg Lui for smuggling servers containing 300 million worth of AI chips to China, in violation of US export laws. Those efforts reportedly show how an expanded network of criminals is attempting to reroute NVIDIA's AI chips to China, profiting from Washington's export controls that make the contraband silicon valuable. NVIDIA says it has abided by the rules and the company has never been accused of abetting smuggling.

Automated scientific discovery promises to accelerate progress across scientific domains. However, developing and evaluating an AI agent's capacity for endto-end scientific reasoning is challenging as running real-world experiments is often prohibitively expensive or infeasible.

Unlike most primary headaches, secondary headaches need specialized care and can have devastating consequences if not treated promptly. Clinical guidelines highlight several 'red flag' features, such as thunderclap onset, meningismus, papilledema, focal neurologic deficits, signs of temporal arteritis, systemic illness, and the 'worst headache of their life' presentation. Despite these guidelines, determining which patients require urgent evaluation remains challenging in primary care settings. Clinicians often work with limited time, incomplete information, and diverse symptom presentations, which can lead to under-recognition and inappropriate care. We present a large language model (LLM)-based multi-agent clinical decision support system built on an orchestrator-specialist architecture, designed to perform explicit and interpretable secondary headache diagnosis from free-text clinical vignettes. The multi-agent system decomposes diagnosis into seven domain-specialized agents, each producing a structured and evidence-grounded rationale, while a central orchestrator performs task decomposition and coordinates agent routing. We evaluated the multi-agent system using 90 expert-validated secondary headache cases and compared its performance with a single-LLM baseline across two prompting strategies: question-based prompting (QPrompt) and clinical practice guideline-based prompting (GPrompt). We tested five open-source LLMs (Qwen-30B, GPT-OSS-20B, Qwen-14B, Qwen-8B, and Llama-3.1-8B), and found that the orchestrated multi-agent system with GPrompt consistently achieved the highest F1 scores, with larger gains in smaller models. These findings demonstrate that structured multi-agent reasoning improves accuracy beyond prompt engineering alone and offers a transparent, clinically aligned approach for explainable decision support in secondary headache diagnosis.

Choosing what pictures to include in your online dating profile is a big deal. Most people want to present a decent mix of flattering, fun and relaxed photos that showcase the best of you. But there are some in particular that should be avoided at all costs, experts say. A team from dating app Wisp asked 1,200 people for their biggest photo red flags that make them swipe left. The survey revealed 83 per cent of singles judge profiles on photos before reading a single word of your personal bio.

Pennsylvania Secretary of State Al Schmidt said mail-in ballots cannot be counted until 7 a.m. on Election Day under state law preventing pre-canvassing, so voters should not expect the final results to be available on election night. Elections are one of the most crucial parts of any democracy, and unfortunately that also means bad actors try to twist things for their own gain. With the U.S. general elections just around the corner, cybersecurity risks are ramping up, not just to the systems running the election but also to you. Social media and the internet are being used to spread propaganda and sway your opinions. What's even more concerning is that these campaigns are now powered by AI tools, making it very easy for bad actors to churn out misleading information at lightning speed and on a huge scale.
