Most people can name at least a few bones of the human body, but not many know about the cytoskeleton within our cells, let alone the “microtubules” that give it its shape. Now, a group of Princeton researchers has resolved a long-standing controversy by identifying exactly how the body creates these micron-sized filaments.

Scientists have recently learned how to use light to control specific groups of neurons to better understand the operation of the brain, a development that has transformed areas of neuroscience.

For more than a century, biologists ignored a fundamental question about how cells do the business of sorting molecules in a crowd. Then came Cliff Brangwynne, whose surprising work showed that certain proteins separate into globules much like droplets of vinegar suspended in oil.
