NASA is embarking on the Sporadic-E ElectroDynamics (SEED) mission, launching rockets from Kwajalein Atoll to investigate unpredictable Sporadic-E layers in the ionosphere. These layers disrupt radio signals, impacting communication and navigation systems. The mission aims to understand their formation and behavior near the magnetic equator, enhancing prediction models to mitigate signal interruptions.

This discovery could transform natural resource acquisition.
A new COVID-19 variant, NB.1.8.1 or "Nimbus," is spreading globally, causing painful sore throats, dubbed "razor blade throat." Primarily affecting the eastern Mediterranean, Southeast Asia, and western Pacific regions, it's been detected in the US. While some Western Pacific countries report increased cases and hospitalizations, current vaccines remain effective, and the WHO considers the public health risk low.
A recent study reveals that fish, including rainbow trout, experience intense pain for several minutes when killed using common methods like air asphyxiation. This suffering extends beyond slaughter, with pre-slaughter stressors also contributing to their distress. Researchers suggest improved stunning methods and worker training to reduce fish suffering and promote more humane practices in fish farming.
SpaceX successfully launched 26 Starlink satellites from California's Vandenberg Space Force Base on Monday. The Falcon 9 rocket, making its third flight, deployed the satellites into low Earth orbit. The rocket's first stage landed on the drone ship in the Pacific Ocean. This launch follows a similar Starlink deployment from Florida, which completed the first-generation Starlink direct-to-cell satellite constellation.
