China's Shenzhou 19 astronauts are conducting a groundbreaking experiment aboard the Tiangong space station, studying 15 adult fruit flies and 40 pupae. The research explores the combined effects of microgravity and sub-magnetic fields on the insects' behavior, growth, and biological rhythms. Led by Zheng Weibo from the Chinese Academy of Sciences, the study mimics deep-space conditions while maintaining an Earth's magnetic field for comparison. The findings aim to advance knowledge in genetics, neuroscience, and the potential impacts of space environments on living organisms, paving the way for future deep-space exploration.
