US scientists Jeffrey Hall, Michael Rosbash and Michael Young won the 2017 Nobel prize for medicine on Monday for unravelling molecular mechanisms that control our internal body clocks. These help explain how people experience jet lag when their internal circadian rhythms get out of sync, while also having wider implications for disorders ranging from insomnia and depression to heart disease. Chronobiology, or the study of biological clocks, is now a growing field of research, thanks to the pioneering work of the three scientists, who explained the role of specific genes in keeping fruit flies in step with light and darkness. Scientists are exploring new treatments based on such circadian cycles, including establishing the best times to take medicine, and there is an increased focus on healthy sleeping patterns.
