The swirling, rotating rainbow of dots in this video is a 3D reconstruction of cell movements in a developing fruit fly embryo. Each dot represents a single cell nucleus, and the dots’ tails represent the last five minutes of the cells’ trajectories. Advances in microscopy have enabled the recording of such embryonic cell movements for some time, but gathering meaningful information from the associated terabytes of image data has been stymied by a lack of computing power – until now. Computational scientists have devised complex algorithms that allow the rapid, accurate and simultaneous tracking of many thousands of cells – their divisions and movements – over many hours of development. And not just in flies – they’ve also tracked cells in developing fish and mouse embryos. This technology should reveal not only how cells move in normal tissue and organ development, but also how erroneous movements lead to developmental defects.

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
