The integrated stress response (ISR) is a well-studied biological circuit that behaves like a disaster response center: it takes control when something in the cell goes awry. When the ISR receives a distress signal, it responds by reallocating cellular resources. Run-of-the-mill cellular functions are shut off so that valuable resources […]

Who among us hasn’t had a sore throat, a hoarse voice or a lump in the neck? Usually, these are minor problems that go away on their own or after a course of antibiotics—but if they don’t, check in with your doctor. These can all be signs of oropharyngeal cancer […]

A novel system to amplify gene expression signals could be a game-changer for scientists who study the regulatory processes in cells that are central to all life.
