Minute differences in individual muscle cell contractions allow the entire muscle to flex with greater control and accuracy. Long dismissed as “noise” or error, experts now suspect that biological systems may have evolved to include unavoidable variation as a form of information in their communication channels. A team of experts from the University of Tokyo published these findings in the scientific journal Cell Reports.


“The differences between cells’ responses to stimulation is actually another form of information,” said Professor Shinya Kuroda, leader of the research lab that performed the experiments at the University of Tokyo Graduate School of Science and a co-author of the recent research publication.

Although robots might be designed to respond identically in unison, each cell in a natural system contains all manner of idiosyncrasies, such as unique patterns of gene expression. Each cell in a muscle
