Bryn Nelson, writing for Science News for Students, visits three research groups doing very different projects on a common theme: proteins. Turns out paleontologists use them to make dinosaur family trees, nutritionists create recipes focused on them to keep kids healthy, and biologists track them to map cells. (Don’t miss the bonus video of dividing cell nuclei and GIF of a rotating cell.) @SeattleBryn and brynnelson.com. image: NIH
