EXTREME CLOSE-UP: An image from the newly produced video of a cell
Scientists have made the most detailed video ever recorded of a living cell in action. The video shows six organelles—specialized structures within a cell—working together to process fat molecules. “It’s the first time we’ve studied so much of a live cell at once,” says Sarah Cohen, a biologist at the National Institutes of Health.
To create the video, Cohen’s team treated each organelle with dye that glowed a different color. Then they used a special microscope to observe the glowing colors and a computer to produce a detailed image of the data. “This technique lets scientists view cells as entire systems, instead of one or two parts at a time,” says Cohen.
This diagram shows some of the major parts of an animal cell.
