    Direct link between illness and the need for more sleep. Humans spend nearly one-third of their lives in slumber, yet sleep is still one of biology’s most enduring mysteries. Little is known about what genetic or molecular forces drive the need to sleep – until now. In a study of over 12,000 lines of fruit flies, researchers from the Perelman School of Medicine at the University of Pennsylvania have found a single gene, called nemuri, that increases the need for sleep. These findings are published today in Science.
