The Trump administration's policies are jeopardizing America's scientific leadership. Funding cuts and anti-immigrant measures are driving away foreign scientists, a key component of US scientific success. This exodus, exemplified by the story of Katalin Karikó, whose mRNA vaccine research benefited greatly from US support, threatens America's innovation and economic competitiveness. While some funding cuts have been blocked, the damage from anti-immigration policies is far more severe and could lead to a decline in scientific breakthroughs and economic growth. Scientists are leaving, and other countries are capitalizing on this opportunity.
