Scientists track chemical changes in cells as they endure extreme conditions
Date:7/7/2009

s, scientists must also understand the ever-changing chemistry inside a cell in order to fully understand its gene expression and adaptive-response pathways.

Scientists have also teased out the chemical changes in the bacterium by studying different cells at various stages in a population of cells. This is not the same as studying the same cell over time, however.

"We are studying the same individuals as opposed to studying the population. We want to watch the same cells over time and not rely on the assumption that all cells within a population behave the same," says Holman. "This work, which represents a new way to study adaptive response in individual cells, is made possible by the great progress we've made in synchrotron infrared cellular imaging."
