Researchers say the U.S. needs federal science dollars to compete with China. President Trump’s fiscal 2018 budget outline, released last month, envisions a dramatically smaller federal investment in science and medicine, while boosting spending on the military and reserving billions for a wall on the Mexico border. The budget blueprint includes cuts to agencies that have traditionally enjoyed bipartisan support, such as the National Institutes of Health. The proposed cuts have added some urgency to the March for Science, which is expected to draw tens of thousands of people Saturday in Washington and in cities around the country.
