A China-led international team has reported a new pre-earthquake phenomenon that has shown strong predictive potential for major earthquakes since 2022 with minimal failures. The anomalous seismic, magnetic and ionospheric resonance signals they observed – termed “seismo-ripples” by the researchers – are ringlike disturbance patterns triggered before earthquakes happen. Their findings challenge the long-standing scientific belief that these events are unpredictable, opening up a promising new...

Chinese researchers have built a self-propelled crawler robot that harvests iron from sand and have tested the device in the dunes of the vast Taklamakan Desert – an area the size of Germany – in northwestern China’s Xinjiang Uygur autonomous region. In Frank Herbert’s classic science fiction novel Dune, mobile factories traverse the sands of the fictional planet Arrakis to extract the drug melange, also known as “spice”. The real-world device similarly travels across the desert, extracting...
