The deaths of multiple prominent scientists in China have raised significant concerns, particularly following the puzzling case of Feng Yanghe, a 38-year-old defense technology professor who died in a car crash in Beijing in July 2023. Feng was reportedly working on Taiwan invasion simulations at the time of his death, which was described in an obituary as a sacrifice during official duties, a phrase unusual for a traffic accident. His burial in a prestigious cemetery reserved for national figures has further fueled speculation. Reports indicate that at least nine scientists have died under similar circumstances, with ages ranging from 26 to 68, many involved in sensitive fields such as military AI and space defense. Despite the unusual clustering of these incidents, officials have not indicated foul play, with the Chinese Embassy in Washington stating they are unaware of the situation. Concerns have also been raised in the United States, where 11 scientists in advanced research have reportedly gone missing or died under unclear circumstances. As global competition in science and defense intensifies, the loss of these experts could have significant implications.
