"The researchers chose to study yeast cells, since they are similar to human cells, and their focus is on glycolytic oscillations -- a series of chemical reactions during metabolism where the concentration of substances can pulse or oscillate. The study showed how cells that initially oscillated independent of each other shifted to being more synchronized, creating partially synchronized populations of cells.

"'One of the unique things with this study is that we have been able to study individual cells instead of simply entire cell populations. This has allowed us to really be able to see how the cells transition from their individual behaviour to coordinating with their neighbours. We have been able to map their behaviour both temporally and spatially, that is to say, when something occurs and in which cell," says Beck Adiels.

"This type of behaviour is also found in cells such as heart muscle cells and in pancreatic cells, which can be an important piece of the puzzle in diabetes research."

Comment: I do not understand how glycolytic oscillations carry messages, but no else knows either. We know DNA carries information in its code. Does the pitch of the oscillations? The advancing research raises more questions than answers.
