Whether you’re a night owl or an early riser, we all sleep. But for something so universal, we don’t understand much about what makes us sleep. Researchers looking into this question recently found a gene called neumri that triggered sleep in Drosophila flies. That gene produced a protein that is linked to antimicrobial activity. The results were published in the journal Science. Neuroscientist Amita Seghal, who is an author on the study, talks about the role sleep might play in sickness and keeping us healthy.
