Digital prints of pollen samples, some of which date back thousands of years, produced by Cardiff University’s bioimaging hub.

As a former secondary school science teacher, Oliver Wilson knows the challenges of communicating big, complex issues. Now, the palaeoecologist is reaching global audiences with a project that brings to life the microscopic world of pollen by producing giant 3D-printed models from high-quality scans of pollen grains. “Being able to identify pollen is important for many reasons,” he says. Because they can survive millions of years and are tiny and tough, they can help track changing climate patterns , reveal the quality of honey and even provide forensic evidence at crime scenes. “But I love seeing what else people do with the models,” he says. Already they have been used by bee ecologists in Brazil, US school teachers and Irish archaeologists, among others. Oliver Wilson holds some examples of the […]
