How a repurposed medical device is helping us investigate ancient climate tipping points

The Conversation · · 692 words · By Edward Forman; Zoë Thomas

The article discusses the application of Imaging Flow Cytometry (IFC), a medical imaging technology, to the field of palaeoclimate research. It explains how IFC allows scientists to analyze microscopic fossils in sediment and peat more efficiently than manual counting, potentially leading to better identification of past climate tipping points.
