Bill Nye the Science Guy plans to headline the upcoming March for Science in Washington.

He joins Mona Hanna-Attisha, the doctor who helped expose lead poisoning in Flint, Mich., as well as a molecular biologist who helped develop the technique for making insulin, Lydia Villa-Komaroff.

Organizers announced yesterday that the three will be honorary co-chairs during the April 22 event on the National Mall.

Nye said before the announcement that he’s never seen the scientific community so energized — or troubled — by political issues.

“Science is what makes our world what it is,” Nye said. “To have a movement or a tendency to set science aside is in no one’s best interest … but nevertheless, that’s what’s happening in the U.S.”

The march has sister events planned in over 400 cities, and it could become one of the scientific community’s largest demonstrations ever (Sarah Kaplan, Washington Post, March 30). — CS
