美科学家焦虑坏了：我的学生们正在返回中国…

Core Viewpoint - The article highlights the significant talent drain from the U.S. scientific community due to budget cuts and restrictive immigration policies under the Trump administration, leading to increased recruitment efforts in China and Europe for top researchers [1][4]. Group 1: Talent Drain and Recruitment Trends - The number of international scholars applying for U.S. graduate or postdoctoral positions has sharply declined since Trump's administration, while applications from U.S. postdocs and graduates for overseas positions have surged [1][4]. - Data from "Nature Careers" indicates a 32% increase in U.S. scientists applying for overseas positions from January to March 2025 compared to the same period in 2024, with a 35% rise in domestic users browsing overseas job listings [4]. - In March 2025, the browsing volume for overseas positions increased by 68% year-over-year, reflecting the growing interest in international opportunities [4]. Group 2: Impact on U.S. Research Institutions - The U.S. scientific system, which has historically relied on international talent, is facing a crisis as federal budget cuts and tightened immigration policies undermine its foundational support [4][10]. - A significant portion of researchers in key fields, such as defense, engineering, and life sciences, are international, with many now seeking opportunities abroad, leading to a potential loss of 30% of the workforce in some departments [10][11]. - Concerns are raised about the isolation of the U.S. from the international scientific community, as foreign scientists are increasingly reluctant to come to the U.S., affecting events and collaborations [10][11]. Group 3: Global Competition for Talent - Other countries, particularly China, are providing more stable career development opportunities for early-career scientists, which may attract top talent away from the U.S. [11]. - The U.S. National Academy of Sciences expresses concern that the current restructuring of the U.S. innovation engine may lead to a significant disadvantage compared to countries like China, which are not cutting their research budgets [11].
