Planetary modeling reveals Jupiter's rapid early growth shaped Earth's formation zone
Los Angeles CA (SPX) Oct 27, 2025 Researchers from Rice University have demonstrated that Jupiter's initial expansion played a pivotal role in organizing the developing solar system. Using advanced hydrodynamic and dust-evolution simulations, planetary scientists Andre Izidoro and Baibhav Srivastava determined that Jupiter's immense gravitational force disturbed the disk of gas and dust encircling the sun. This disturbance halted particles from spiraling into the sun and concentrated material into dense bands, promoting the creation of ... read more |

Rock record illuminates oxygen history
Syracuse NY (SPX) Jun 02, 2025 Several key moments in Earth's history help us humans answer the question, "How did we get here?" These moments also shed light on the question, "Where are we going"? - offering scientists deeper insight into how organisms adapt to physical and chemical changes in their environment. Among them is an extended evolutionary occurrence over 2 billion years ago, known as the Great Oxidation Event (GOE). This marked the first time that oxygen produced by photosynthesis-essential for the survival of humans and ... read more
