Summary – Till now, it’s only been possible to track where cells are in their life cycle once they’re dead. But now, a new study outlines a method of analyzing living cells by taking a close look at their nucleus.

A new study published in Eeurekalert, by researchers at New York University (NYU), has established a method of gauging what stage of the cells cycle a living cell is currently at.

Previously, it was only possible to take such measurements when working with a dead cell.

It was already known that the size and shape of a cell nucleus typically undergo big changes over the course of a cell’s lifespan. However, the challenge of taking the measurement from a living cell meant that we didn’t know whether its shape changed over a short span of time.

Using a cutting-edge fluorescence microscope, researchers were able to observe a previously undetected flicker of the nuclear envelope, which takes place over the course of just a few seconds. The amplitude of this fluctuation was seen to decrease as the cell cycle went on.

Being able to discern where a cell sits in its life cycle will hopefully facilitate a greater understanding of the most basic processes of human biology.

This discovery stands to improve our knowledge of both healthy and diseased cells.

    We are getting old because of the reduction of cell generation as well as prolong life on existing cells. Scientists are trying to implicate and replicate cells in order to live longer.

  2. This is cool, but it is also a little scary. It could eventually allow people to find out their exact time/date of death; this could either make people paranoid or give people the vision that life is shorter than they think. People could go out and actually live or live in fear for the rest of their life.

    Just my opinion about this. :upside_down_face:
