‘The Oldest Living Things in the World’

What’s older than dirt? The stuff that New York-based artist Rachel Sussman discovered on a decadelong journey around the world to track down organisms 2,000 years old or older. She photographed lichens in Greenland that only grow one centimeter per 100 years; an 80,000-year-old colony of aspen trees in Utah, and a 5,500-year-old moss in Antarctica. Her exhibition presents some of the photos from her journey. Ultimately, her work is a call to action on climate change and the risks that humans pose to the land; two of her organic subjects are already gone. Her complete findings are available as a book.(Opening reception 6-9 p.m. Fri. Artist talk at 1 p.m. Sat., RSVP required. Regular hours 10 a.m.-4 p.m. Mon.-Fri. through April 15. NewStudio Gallery, 2303 Wycliff St., St. Paul. Free. 651-285-2287 or newstudioarchitecture.com.)
