Physicists associated with Carnegie Mellon have created a new program, known as TARDIS, to track multiple particles in liquids. "The limits with single particle tracking were always that you had to look at one particle at the same time, and with TARDIS, that's simply not a limit anymore," said Martens, a former postdoctoral fellow in Department of Physics now at the University of Bonn. https://www.cmu.edu/mcs/news-events/2024/0206_tardis-martens.html | Mellon College of Science at Carnegie Mello
