Northern Arizona University is home to a giant collection of dried plant specimens that scientists across the globe use as a resource center. The Deaver Herbarium is essentially a plant museum that holds more than 120 thousand samples from the Southwest, some gathered more than 100 years ago. Biologist Tina Ayers is the director and curator. 


More than 500-cities worldwide are participating in Saturday’s March For Science. Organizers say it’s a chance to bring awareness to the “very real role” science plays in our lives. Some are concerned the march will fuel the idea that the science community is a special interest group that politicizes its work. Others see it is a chance to celebrate the integrity of research and evidence. Todd Gonzalez is an educator at Lowell Observatory, and a speaker at tomorrow’s march in Flagstaff, one of seven Arizona cities participating. Gonzalez told KNAU’s Aaron Granillo he’s not worried about looking partisan.
