A 3000-year-old copper smelting site could be key to understanding the origins of iron
Research from Cranfield University sheds new light onto the transition from the Bronze Age to the Iron Age, showing how experimentation with iron-rich rocks by copper smelters may have sparked the invention of iron. Published in the Journal of Archaeological Science, the work reanalyzed metallurgical remains from a site in southern Georgia: a 3000-year-old smelting workshop called Kvemo Bolnisi. During the original analysis in the 1950s, piles of hematite (an iron oxide mineral) and slag (a waste product of the metal production) were found in the workshop.

President Donald Trump posted on Saturday a cartoon image depicting him firing Federal Reserve Chairman Jerome Powell. The post on Truth Social was an image of himself pointing his finger and shouting "YOU'RE FIRED!" to Powell, who was holding a box with his belongings. Behind them is a depiction of the seal of the Federal Reserve. The image appears to be "AI-generated or digitally illustrated," according to visual analysis by ChatGPT. Trump has repeatedly criticized Powell for his cautious approach to cutting interest rates, nicknaming him "Too Late Powell." The latest threat came even as the central bank lowered rates earlier this month for the first time this year. Powell's term as chair ends in May 2026. The White House didn't immediately respond to CNBC's request for comment. Firing the top central banker would be unprecedented as no U.S. president ever has attempted to do so, though others have criticized prior Fed chairs. A recent Supreme Court decision indicated that the president does not have the authority to remove Fed officials at will. Powell has said repeatedly that his firing is "not permitted under the law." The Trump White House has blasted Powell over renovations to the Fed's Washington headquarters, raising suspicion that Trump could try to remove the Fed leader for cause.
