Scientists have discovered that Earth's magnetosphere has an opposite charge distribution than previously believed, with the morning side negatively charged and the evening side positively charged, due to plasma motion and magnetic field interactions, challenging traditional theories and enhancing understanding of space weather phenomena.
Dust devils on Mars may generate lightning due to charge buildup in dust particles, posing potential risks to rovers like NASA's Perseverance, while also offering new insights into Martian atmospheric phenomena. The study uses computer models to explore how dust particle size and charge distribution could lead to electrical discharges, with recent evidence suggesting lightning might have been observed by the rover's microphone.
Researchers at Oak Ridge National Laboratory have developed a groundbreaking approach using spiral-tip motion and image reconstruction techniques to understand the behavior of electric charge at the microscopic level, potentially leading to improvements in batteries, solar cells, and electronic devices. Their method allows visualization of charge motion at the nanometer level and at speeds thousands of times faster than conventional methods, providing a rapid and thorough view of processes previously unattainable. This approach expands the toolkit available to users at the Center for Nanophase Materials Sciences at ORNL, enabling exploration across various devices and materials.
