In the wake of the Second World War, US leaders adopted the view that scientific progress is an “essential key to our security as a nation, to our better health, to more jobs, to a higher standard of living, and to our cultural progress”. And for the next eight decades, government officials on both sides of the political aisle agreed to invest in US science. Just one month into the second administration of Republican President Donald Trump, scientists fear that that long-time consensus is disintegrating.

Acting with unprecedented speed, the administration has laid off thousands of employees at US science agencies and announced reforms to research-grant standards that could drastically reduce federal financial support for science. The cuts form part of a larger effort to radically reduce the government’s spending and downsize its workforce.
