Science Not Silence

Thousands of scientists and supporters of science are painting protest signs, filling their water bottles and laying out their walking shoes for the first-ever March for Science in Washington on April 22, 2017. Scores of events are planned in other cities too. Some scientists are boycotting, fearful the march will tarnish the credibility of science. But Marnie Halpern, on the faculty of the Carnegie Institution for Science, plans to take part with a busload of colleagues. She says it's less about protesting policies of the Trump administration than about normally reticent scientists shining a light on their research.
