Cosmic Rays and Silent Data Corruption in Data Centres
Cosmic-ray neutrons are real, but field studies point to hardware defects behind most DRAM faults and the silent core errors operators have traced.

Why Zillow Offers Failed: Sellers Said Yes to Its Mistakes
Why did Zillow Offers fail? Sellers accepted the offers its model got wrong, staff pushed bids higher, and your Zestimate carries the same risk.
Moon Illusion: The Horizon Moon Is Farther and Smaller
The moon illusion makes a rising Moon look enormous. Measured, that Moon is about 1.66% farther away than the one overhead, and smaller.
AI Energy Per Query: Same Prompt, Two Different Numbers
AI energy per query differs 2.4x for the same median prompt depending on method, and the popular figure answers a narrower question.
AI Model Collapse Is a Curation Failure
AI model collapse comes from uncurated synthetic data, and the text shortage only pushes labs toward it. Curation decides which labs keep improving.
Why the LHC Is Colder Than Outer Space, On Purpose
Why is the LHC colder than outer space? At 1.9 kelvin helium turns superfluid, and that quantum threshold keeps the LHC's magnets from quenching.
PII Masking AI Agent: The New Privacy Default
PII masking AI agent design is quietly becoming standard — six unrelated vendors converged on mask-then-send without comparing notes.
Claude Unified Memory Is a Trust Play, Not a Feature
Claude unified memory now spans Chat and Cowork — the real story is the delete button Anthropic shipped first, not the recall.
MoS2 Radio Survives Nine Months in Orbit: What It Shows
A 2026 orbital MoS2 radio experiment ran for nine months. Its measured error rate supports a promising result, with mission qualification still ahead.
AI Trading Agents Are Losing Real Money Fast
Alpha Arena gave six frontier models $10,000 each to trade crypto with no human sign-off. GPT-5 finished last at -62.66%. Only Qwen and DeepSeek profited.
Claude Code Built-In Browser Closes the QA Loop
Claude Code's built-in browser isn't for browsing — it's how your coding agent QA-tests its own work against the live web.
AI Agent Memory Is About Cost, Not Feelings
AI agent memory isn't agents finally understanding you, it's a cost-and-latency fix you can wire in this week.
