The Ada Hayden Herbarium preserves hundreds of thousands of specimens, including some collected by George Washington Carver. And, as the “Universe of Art” podcast turns one, listeners discuss solar music boxes and what it’s like making art with Chronic Fatigue Syndrome.

Herbariums are plant libraries—they contain fragile specimens of plants collected from near and far, and they are meticulously described and cataloged so that someone can reference them in the future. At Iowa State University, the Ada Hayden Herbarium contains more than 700,000 specimens, about half of which are from Iowa.

Ira talks with herbarium’s director, Dr. Lynn Clark, and curator Deb Lewis about how plants are preserved, why herbariums are so important, and what it takes to manage a plant archive.

Last week, we kicked off a first-anniversary celebration for Universe of Art, our science-meets-art spinoff podcast. A lot of listeners have written in since the start of the podcast, telling us about the science-inspired art they’ve made in their spare time.

Last week, host D. Peterschmidt spoke with Todd Gilens, a visual designer who worked with the city of Reno, Nevada, to create a mile-long poem on the city’s sidewalks about the connections between urbanism and stream ecology.

This time, we’ll meet two listeners. Craig Colorusso is a punk rock guitarist-turned-sound artist who creates public sculptures and experiences that enhance visitors’ connection to nature. Two of his projects, Sun Boxes and The Bridges At Coler, use solar panels to play reflective, calming music he composed. “You have this idea where you are in nature and you are listening to something that is powered by nature,” he said. “I think that’s perfect.”

And we’ll meet a listener who prefers to go by Chris, who was an engineer and avid artist who made mosaics and crocheted before developing Myalgic Encephalomyelitis, or Chronic Fatigue Syndrome (ME/CFS). It’s a debilitating condition characterized by extreme fatigue that can’t be improved by rest, and can also include brain fog, pain, and dizziness. It’s similar to what many Long COVID patients experience. Chris’ condition is considered severe, and caused her to lose the use of her hands, and thus her preferred art mediums.

However, Chris could still use her left hand with a rollerball mouse and realized that she could use programs like Chaotica to create fractals that she adds to collages in Photoshop, resulting in colorful collages. “They’re just beautiful and I’m doing art again and I’m so happy about it,” she said.

Transcripts for each segment will be available after the show airs on sciencefriday.com.
