AI Cracks NIST Post-Quantum Finalist in 60 Hours
55+ min ago (511+ words) The list of post-quantum signature schemes that looked unbreakable until they weren't just got one name longer. Rainbow fell to a laptop in a weekend. SIKE fell in about an hour. HAWK — the last lattice-based candidate standing in NIST's additional…...
Why Your Best Predictive Model Gives the Wrong Treatment Effect
4+ hour, 38+ min ago (1282+ words) Why prediction-driven variable selection misses confounders and how Bayesian Adjustment for Confounding attempts to fix it. Model selection often chases the wrong goal. Let’s say we want to estimate the effect of an exposure on an outcome, e.g., air…...
Renoise and GPT Image 2: A Practical AI Workflow
6+ hour, 41+ min ago (770+ words) AI image generation is now used for advertising, product launches, social media, presentations, and branded content. One model rarely handles every task equally well. A project may require readable text, accurate references, fast variations, detailed editing, or a distinctive style....
What Happens When Two Miners Find a Block at the Same Second? Inside an Orphan Race
37+ min ago (434+ words) Bitcoin mining is a race with no referee watching the finish line in real time. A new block has to physically propagate (i.e. hop from node to node) across a global network before every participant agrees on what the current tip…...
When Two Worlds Collide: How Collisions Between Silicate and Carbonaceous Nanograins can Drive Complex Chemistry
3+ hour, 22+ min ago (139+ words) For all collisions, we tracked the extent of grain-grain mixing and the formation of molecular fragments. We identified four velocity regimes: 1) 7.5 km/sec, where fragmentation dominates. The latter regime produces CO as the main product, along with hydrocarbons, complex organic…...
Building Persistent Context for Coding Agents
12+ hour, 19+ min ago (574+ words) The capability is not the constraint anymore. The agents can do the work. What breaks down is everything around the work: holding the right context, keeping the agent pointed at the goal across many steps, and trusting what comes back…...
Neurosymbolic AI: Why the Next Wave of AI Research Needs a Different Kind of Talent | Deep Tech Recruitment Agency · DeepRec
2+ hour, 29+ min ago (1012+ words) Large language models have changed expectations of what artificial intelligence can achieve. They can write code, answer complex questions and generate convincing text in seconds, yet they still struggle with logical reasoning, long-term planning and explaining how a conclusion was…...
Hidden Patterns, New Possibilities – Purdue Researchers Combine Neuroscience and Machine Learning to Uncover Clues about How Seizures Develop and Spread | Purdue University College of Veterinary Medicine
3+ hour, 50+ min ago (817+ words) For decades, scientists have viewed seizures as moments when the brain’s neurons fire together in a synchronized storm of electrical activity. New research from Purdue University reveals the brain’s story is far more complex. The interdisciplinary research, led by Riyi…...
AI Weekly: Opus 5 Lands, MCP Goes Stateless, and AMD Ships Helios
57+ min ago (1713+ words) Week of July 22 to July 29, 2026 Starting this issue, the newsletter runs the same four sections every week in the same order: models, tooling, standards, infrastructure. Models set what is possible. Tooling decides who gets to use it. Standards decide whether…...
Apache Data Lakehouse Weekly: July 21 to July 29, 2026
57+ min ago (981+ words) Here is what happened, project by project. This is the kind of decision that defines a format version. V2 gave the ecosystem row-level deletes. V3 gave it deletion vectors and new types. V4 looks like the version where the community trims the surface…...
