Scientists in the US have developed a device that can generate tiny amounts of electricity by harnessing Earth's rotation and magnetic field, suggesting a potential, though currently impractical, new energy source if scaled up. The experiment involved a specially shaped ferrite shell that avoids the usual cancellation of voltage caused by electromagnetic forces, producing measurable microvolts as Earth spins. While promising, the technology is in early stages, and further independent testing is needed to verify and explore its scalability.

New research suggests that Earth's atmosphere has been gradually leaking particles, including water and nitrogen, to the Moon over billions of years, facilitated by Earth's magnetic field, which acts more like a guiding rail than a shield. These particles are preserved in lunar soil, creating a long-term archive of Earth's atmospheric history and potentially providing resources for future lunar exploration.

A study suggests that gravitational tidal forces from Venus, Earth, and Jupiter may help keep the sun calmer than other stars, potentially reducing the risk of extreme solar storms that could disrupt Earth's technology. These forces influence the sun's magnetic activity in a cyclical manner, possibly explaining why our sun's eruptions are milder compared to similar stars, which may have contributed to Earth's habitability.
