Scientists have used cells as a recording device for the first time
For the first time, scientists have used a cell to record what happens in the world around it. They were able to retrieve the information and read it in chronological order.
Why it matters: Changes in temperature and chemical levels inside the body can be recorded in a broad sense, but tools like this are the biological equivalent of using a microscope versus a magnifying glass. "It's the next generation of resolution," says study author Harris Wang, a synthetic biologist at Columbia University.
