Scientists discover new golden-tongued lizard in China
Researchers in China have identified a previously unknown species of mountain lizard in the upper Dadu River Valley within the Hengduan Mountains of Sichuan Province. Named Diploderma bifluviale, the lizard features a distinctive wheat-colored tongue and thrives in semi-arid shrublands at high elevations. This finding highlights the region's understudied biodiversity.
New tektites reveal ancient asteroid impact in South Australia
Researchers have uncovered a new field of 11-million-year-old tektites in South Australia, pointing to a massive asteroid impact whose crater remains undiscovered. These unique glass fragments differ chemically and geographically from known tektites, recording an event previously unknown to science. The finding highlights Earth's violent past and aids planetary defense efforts.
Simulation reveals origin of Earth's magnetic field in liquid core
Reported by AI
Geophysicists have simulated how Earth's magnetic field could emerge from a fully liquid core, challenging previous assumptions. By minimizing viscosity effects, the model shows a self-sustaining dynamo similar to today's. The findings, published in Nature, shed light on planetary history and future magnetic changes.
Scientists pinpoint tremors beneath Tanzania's Oldoinyo Lengai volcano
Researchers have traced tremor signals deep inside Tanzania's Oldoinyo Lengai volcano, locating them in three dimensions for the first time. The study reveals linked tremors at varying depths, providing insights into magma and gas movement. This unique carbonatite volcano's fluid, cool magma produced unexpected results that could improve eruption forecasting.
