Scientists present a new method for imaging individual electrons

Imagine going for an MRI scan of your knee. This scan measures the density of water molecules present in your knee, at a resolution of about one cubic millimeter—which is great for determining whether, for example, a meniscus in the knee is torn. But what if you need to investigate the structural data of a single molecule that’s five cubic nanometers, or about 10 trillion times smaller than the best resolution current MRI scanners are capable of producing?
