Phys.org (June 19) -- In each of our bodies, more than 37 trillion cells tightly coordinate with other cells to organize into the numerous tissues and organs that make us tick. An international team made up of researchers from eight different labs, including the University of Illinois at Urbana-Champaign, are colloborating on research to better understand the physical forces and how best to optimize available technology. They wanted to compare different common techniques and understand the differences in the results of those techniques.
