About Time: When Reinforcement Learning Finally Learns to Wait

Opening — Why this matters now Reinforcement learning has become remarkably good at doing things eventually. Unfortunately, many real-world systems care about when those things happen. Autonomous vehicles, industrial automation, financial execution systems, even basic robotics all live under deadlines, delays, and penalties for being too early or too late. Classic RL mostly shrugs at this. Time is either implicit, discretized away, or awkwardly stuffed into state features. ...

Same Moves, Different Minds: Rashomon Comes to Sequential Decision-Making

Opening — Why this matters now Modern AI systems are increasingly judged not just by what they do, but by why they do it. Regulators want explanations. Engineers want guarantees. Businesses want robustness under change. Yet, quietly, a paradox has been growing inside our models: systems that behave exactly the same on the surface may rely on entirely different internal reasoning. ...

When Reasoning Meets Its Laws: Why More Thinking Isn’t Always Better

Opening — Why this matters now Reasoning models are supposed to think. That’s the selling point. More tokens, deeper chains, longer deliberation—surely that means better answers. Except it doesn’t. As Large Reasoning Models (LRMs) scale, something uncomfortable is emerging: they often think more when they should think less, and think less when problems are actually harder. ...

ASKing Smarter Questions: When Scholarly Search Learns to Explain Itself

Opening — Why this matters now Scholarly search is quietly broken. Not catastrophically — Google Scholar still works, papers still exist — but structurally. The volume of academic output has grown faster than any human’s ability to read, filter, and synthesize it. What researchers increasingly need is not more papers, but faster epistemic orientation: Where is the consensus? Where is disagreement? Which papers are actually relevant to this question? ...

Cloud Without Borders: When AI Finally Learns to Share

Opening — Why this matters now AI has never been more powerful — or more fragmented. Models are trained in proprietary clouds, deployed behind opaque APIs, and shared without any serious traceability. For science, this is a structural problem, not a technical inconvenience. Reproducibility collapses when training environments vanish, provenance is an afterthought, and “open” models arrive divorced from their data and training context. ...

When Agents Agree Too Much: Emergent Bias in Multi‑Agent AI Systems

Opening — Why this matters now Multi‑agent AI systems are having a moment. Debate, reflection, consensus — all the cognitive theater we associate with human committees is now being reenacted by clusters of large language models. In finance, that sounds reassuring. Multiple agents, multiple perspectives, fewer blind spots. Or so the story goes. This paper politely ruins that assumption. ...

When Tensors Meet Telemedicine: Diagnosing Leukemia at the Edge

Opening — Why this matters now Healthcare AI has a credibility problem. Models boast benchmark-breaking accuracy, yet quietly fall apart when moved from lab notebooks to hospital workflows. Latency, human-in-the-loop bottlenecks, and fragile classifiers all conspire against real-world deployment. Leukemia diagnosis—especially Acute Lymphocytic Leukemia (ALL)—sits right in the crosshairs of this tension: early detection saves lives, but manual microscopy is slow, subjective, and error-prone. ...

Black Boxes, White Coats: AI Epidemiology and the Art of Governing Without Understanding

Opening — Why this matters now We keep insisting that powerful AI systems must be understood before they can be trusted. That demand feels intuitively correct—and practically paralysing. Large language models now operate in medicine, finance, law, and public administration. Yet interpretability tools—SHAP, LIME, mechanistic circuit tracing—remain brittle, expensive, and increasingly disconnected from real-world deployment. The gap between how models actually behave and how we attempt to explain them is widening, not closing. ...

Prompt-to-Parts: When Language Learns to Build

Opening — Why this matters now Text-to-image was a party trick. Text-to-3D became a demo. Text-to-something you can actually assemble is where the stakes quietly change. As generative AI spills into engineering, manufacturing, and robotics, the uncomfortable truth is this: most AI-generated objects are visually plausible but physically useless. They look right, but they don’t fit, don’t connect, and certainly don’t come with instructions a human can follow. ...

Stop or Strip? Teaching Disassembly When to Quit

Opening — Why this matters now Circular economy rhetoric is everywhere. Circular economy decision-making is not. Most end-of-life products still follow a depressingly simple rule: disassemble until it hurts, or stop when the operator gets tired. The idea that we might formally decide when to stop disassembling — based on value, cost, safety, and information — remains oddly underdeveloped. This gap is no longer academic. EV batteries, e‑waste, and regulated industrial equipment are forcing operators to choose between speed, safety, and sustainability under real constraints. ...
