In this episode of Discover Daily, we explore two groundbreaking developments: DeepMind's release of AlphaFold3's source code, which marks a significant advancement in predicting protein structures and holds great promise for drug discovery, and China's ambitious "Solar Great Wall" project. This vast solar initiative aims to power Beijing while addressing desertification and supporting rural economies. While AlphaFold3 opens exciting new avenues for medical research, the Solar Great Wall, despite its impressive scale, raises questions about its long-term ecological effects and sustainability within China's intricate energy landscape.
