Brain learns faster from rare rewards than from repetitionhttps://www.spacedaily.com/reports/Brain_learns_faster_from_rare_rewards_than_from_repetition_999.htmlLos Angeles CA (SPX) Feb 20, 2026 More than a century after Pavlov trained dogs to link a bell with food, neuroscientists at the University of California, San Francisco report that the brain may rely more on the timing of rewards than on sheer repetition when forming associative memories of cues and outcomes. Their work suggests that what matters for learning is how far apart cue-reward experiences are spaced in time, rather tha

Simple collapse may build cosmic snowman worldshttps://www.spacedaily.com/reports/Simple_collapse_may_build_cosmic_snowman_worlds_999.htmlNew York (SDX) Feb 23, 2026 Astronomers have puzzled over why many icy worlds in the distant Kuiper Belt look like snowmen, with two round lobes joined together. New work from Michigan State University points to a surprisingly simple explanation: these so called contact binaries can form directly through gravitational collapse. Far beyond Neptune, the Kuiper Belt holds icy, largely untouched planetesimals that preser

Show HN: Touch Trigonometry – interactive way to understand the trig functionshttps://apps.apple.com/us/app/touch-trigonometry/id6758712159I started to teach myself to code around 15 years ago. At the time I was working service industry jobs (restaurant kitchens, coffee shops) and desperate to change my career and life.Around that time there was a new thing called available in HTML5 that you could use to render graphics in web pages without plugins; despite my limited knowledge of tech and lack of coding skills, I knew I wanted to be a part of that.Around that same time, I had also enrolled at the community college for night classes in math. I wanted to "work in tech" after all, so a mathematics brush-up seemed wise. I had always struggled with math. But now that I was both incentivized to learn it, I found myself facing a familiar terror: trigonometry.The other students, just out of high school, seemed to know this stuff. I was simply confused. The same frustration I had felt in high school returned: No one could clearly answer why this stuff worked. Why did we need a "sine" function?So I decided to combine my struggles

Show HN: Irpapers – Visual embeddings vs. OCR trade-offs in scientific PDFshttps://github.com/weaviate/query-agent-benchmarkingHey HN, we are releasing IRPAPERS to answer a highly pragmatic question: when building a RAG pipeline over PDFs, should you OCR the text or just embed the raw page images?Processing PDFs in production usually involves stringing together brittle OCR heuristics. While recent multimodal embeddings (like ColModernVBERT or ColPali) allow you to skip OCR entirely and retrieve directly from visual layouts, we wanted to measure if the computational overhead is actually worth the utility.The short answer: Transformer-based image pipelines won't be perfect for every use-case, but they fix exactly what OCR breaks.Here is what we found benchmarking 3,230 pages of dense scientific literature:Complementary Bottlenecks: Text representations (BM25 + dense vectors) are highly efficient for exact lexical constraints (e.g., finding a specific acronym like "HyDE"). Conversely, image embeddings shine on spatial architecture diagrams and t-SNE plots where OCR serialization just turns into structural garbage

Show HN: Aethene – Open-source AI memory layerhttps://github.com/akhilponnada/aetheneHey HN, I'm shipping my first open-source project and I'm pretty nervous about it. Aethene is an AI memory API – it gives your AI apps persistent memory. Store conversations, extract facts automatically, search semantically, handle contradictions gracefully. It works well thank most of the memory projects available on the market currently.Why I built this: I was building AI agents and kept running into the same problem – they forget everything. Every conversation starts from zero. I wanted something that could: - Auto-extract facts from conversations (not just store raw text) - Handle "user moved from SF to NYC" without keeping both as true - Search by meaning, not just keywords - Version everything (who said what, when) Tech stack: - TypeScript + Hono (fast, edge-ready) - Convex (real-time DB + vector search) - Gemini (embeddings + extraction) What it does: # Store memory curl -X POST /v1/content -d '{"content": "User loves hiking, lives in SF"}' # Recall naturally curl -X POST /v1/re
