Have you ever wondered what’s at the center of the earth? #YahooPartner That question sent me down a wild rabbit hole — from a secret drilling mission during the Cold War to an environment so extreme that solid rock began behaving like plastic the deeper we dug. I used Yahoo’s new AI-powered answer engine, Yahoo Scout, to research this story and pull together the science, visuals, and sources all in one place. Built on Yahoo’s 30+ years of search, it combines traditional web results with generative AI to surface clear, compelling answers. They’re also partnering with Anthropic, so the model behind it is incredibly powerful. I’m excited about it — curiosity always leads to the best discoveries. You can try at scout.com and in the Yahoo Search app.
