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…...

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…...

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....

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…...

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…...

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…...

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…...

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…...

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…...

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…...
