These pins defend scientists and science in the Trump era

The couple behind the pins that said "I love you" in American Sign Language, made for the Women's March in January, are back with a new pin raising money for science and research.

Ahead of the "March for Science" on April 22 in Washington, D.C. and all over the world, Kate Lind and Nate Stevens of Pincause designed a new pin with illustrator Penelope Dullaghan. This one says "Science not silence," with a rocket ship launching into space.

"This is a critical time for not just the science community, but for humanity and our planet. Staying silent is no longer an option," Lind said in an email.
