🔬 Earth's Core Just Reversed Direction — And That's Not Even the Wildest Thing Science Dropped This Week

Researchers have discovered that Earth's molten iron core suddenly reversed direction beneath the Pacific Ocean, raising urgent questions about our planet's magnetic field and what it means for life on the surface. Meanwhile, scientists at UC Berkeley have uncovered genetic evidence of not one but two mysterious 'ghost ancestors' hidden in modern human DNA — older than Neanderthals and still unidentified by any known fossil. A wearable ultrasound patch showed it could dramatically boost REM sleep without drugs or surgery, while new research may have finally explained how GLP-1 drugs like Ozempic quiet addiction-related cravings deep in the brain. From a 30-million-year-old tree-climbing dog fossil to Megalodon vertebrae hiding in plain sight on a museum shelf, this episode is packed with discoveries that rewrite what we thought we knew.Subscribe to Peer Review'd Newsletter: https://peerreviewd.com/Love Science?
