The recent changes in the US research and political landscape, particularly following the new administration of President Donald Trump, are having a profound negative impact on the US scientific and medical communities. Drastic cuts to research funding, widespread layoffs of federal scientists, immigration crackdowns, and concerns over academic freedom are leading to a significant exodus of talent from the United States. This briefing document outlines the main themes and important facts from the provided sources, highlighting the distress and uncertainty within these sectors and the increasing interest among US scientists and doctors in relocating to countries like Europe and Canada.

Key Themes and Findings:

1. Mass Exodus of Scientists Driven by Funding Cuts and Uncertainty:

• A Nature poll revealed that 75% of US scientists who responded (over 1,200 out of 1,600) are considering leaving the United States following the disruptions prompted by the Trump administration.
• "More than 1,200 scientists who responded to a Nature poll — three-quarters of the total respondents — are considering leaving the United States following the disruptions prompted by Trump." (Nature News)
• This trend is particularly strong among early-career researchers, with a large majority of postgraduate researchers (548 out of 690) and PhD students (255 out of 340) considering leaving.
• The primary drivers for this consideration are slashed research funding due to a government-wide cost-cutting initiative led by Elon Musk, and the halting of broad swathes of federally funded science.
• "Trump’s administration has slashed research funding and halted broad swathes of federally funded science, under a government-wide cost-cutting initiative led by billionaire Elon Musk." (Nature News)
• Tens of thousands of federal employees, including many scientists, have been fired and rehired following a court order, creating further instability and fear of future job losses.
• Researchers are experiencing uncertainty and disruption across all aspects of the US research enterprise due to immigration crackdowns and battles over academic freedom.
