🛰️ 👀 I spotted over 🇮🇹Italy, during yesterday's Naples earthquake, a cloud formation identical to the one that went viral after the major earthquake in 🇯🇵Japan! 👇 ☁️ A cloud formation remarkably similar to the anvil cloud that went viral after the Mw 7.1 earthquake in Japan was visible in satellite imagery just hours before yesterday’s Mw 4.7 earthquake near Naples, Italy. 📈 Despite the massive difference in earthquake magnitude, the cloud structures are strikingly similar. This highlights a crucial point: ☁️ Cumulonimbus Incus (anvil) clouds are a natural product of intense atmospheric convection. Warm, moist air rises rapidly; upon reaching the tropopause, it can no longer ascend and spreads outward, creating the characteristic anvil-shaped top. After major earthquakes, people naturally tend to associate unusual atmospheric phenomena with seismic activity—a classic confirmation bias. However, available meteorological evidence indicates that both cloud formations are fully explained by standard atmospheric physics. Science is about identifying causation—not just noticing similarities. 🫆 Follow Jeo Albant for more analysis. Retweet if you find this useful! 🔄 ℹ️ Satellite Analysis: The cloud shows classic convective vertical growth (17:20–18:30 TSI) followed by horizontal spreading at the tropopause level (18:50–19:40 TSI), forming the distinct anvil (Cumulonimbus Incus) structure—identical to the one seen in Japan. #CampiFlegrei #TerremotoNapoli #Meteo #Sismologia #地震雲 #地震 #熊本地震 #Earthquake #cloud #Satellite #Meteorology #Naples #ItalyEarthquake #Science #Geology #deprem #bulut

Breaking: Hubble Telescope Opens a "Window" into the Dark Universe — First-Ever Detection of a Starless Dark Matter Cloud! In a groundbreaking discovery announced by NASA, the Hubble Space Telescope has revealed an entirely new class of cosmic object: a vast, starless cloud dominated by dark matter, rich in gas but completely devoid of stars. Nicknamed Cloud-9, this enigmatic structure lies about 14 million light-years away, on the outskirts of the spiral galaxy Messier 94 (M94).This is the first confirmed observation of such a "failed galaxy" or relic from the early universe — a massive dark matter halo that gathered hydrogen gas but never triggered star formation. Hubble's deep imaging ruled out any hidden faint stars, confirming it's truly dark and star-free.Key highlights from the discovery:Massive dark matter core — estimated at around 5 billion solar masses, anchoring a compact reservoir of gas. A cosmic fossil — likely a survivor from the universe's infancy, halted during reionization (when the first stars and galaxies lit up and ionized surrounding gas). Implications — This "phantom" object provides direct evidence for the existence of low-mass dark matter halos that never evolved into full galaxies. It suggests the universe could be filled with similar invisible structures, offering a major boost to our understanding of dark matter and galaxy formation. For decades, theorists predicted these "dark galaxies" or RELHICs (Reionization-Limited Hydrogen Clouds), but Cloud-9 marks the first solid proof caught in the act.Scientists are buzzing — this rare "wow" moment could rewrite parts of cosmic history and hint at countless other hidden building blocks of the universe lurking in the shadows.(Source: NASA/ESA Hubble release, January

Karpathy's Agentic Engineering finally has proper tooling! (built by Google) Karpathy defined agentic engineering as the discipline that separates production agent work from vibe coding. The core skills he listed were spec design, eval loops, and security oversight. The problem has been that practicing this still requires a different tool for every phase: - editor for code - a terminal for scaffolding - a browser for testing - a cloud console for deployment - and a separate framework for evals. Every transition is a context switch. The solution to production-grade Agentic Engineering is now actually implemented in Google’s Agents CLI. It covers the entire workflow in one place for scaffolding, evaluating, and deploying ADK agents. One setup command injects 7 ADK-specific skills into a coding agent's context, which lets it handle scaffolding, evals, deployment, and enterprise registration through natural language. I tested this end-to-end by building a RAG agent from scratch using Claude Code. It scaffolded the full project from the ADK agentic_rag template, generated 20 eval scenarios with LLM-as-judge scoring, and returned a quantitative scorecard. Finally, it also deployed everything to Agent Runtime and registered the agent to Gemini Enterprise, so the entire org can discover and use it. The video below shows this in action, and I worked with the Google Cloud team to put this together. Agents CLI GitHub repo → (don't forget to star it ⭐ ) I wrote up the full build covering all six steps from install to enterprise registration. It includes the eval scorecard, the instruction loophole the eval caught before deployment, and what the deployment process actually looks like end-to-end. Read it below.
