Colossal Structures Within the Earth, DARPA’s New Deep-Space Network, and Genetically Engineered Fungi for Food

This week in news from The Debrief, researchers have uncovered new clues about two colossal, continent-sized structures buried 1,800 miles beneath Earth’s surface—anomalies once dismissed as “random oddities,” now believed to preserve chemical fingerprints from the planet’s earliest formation. Meanwhile, DARPA has launched TBD2, the first deep-space surveillance network designed to track tiny spacecraft millions of miles from Earth, marking a major leap in real-time monitoring of the Earth–Moon system. And in the realm of food innovation, scientists have engineered a genetically modified protein-producing fungus that could rival conventional livestock, offering a more efficient and environmentally sustainable alternative to meat.
