APPLAUSE
Resounding applause for one of the newest Nobel laureates. Michael Young, part of a trio of US scientists recognized for their research into what makes us tick.>> The Nobel assembly at Karolinska Institutet has today decided to award the 2017 Nobel Prize in physiology or medicine jointly to Jeffrey C.

Hall, Michael Rosbash and Michael W. Young for their discoveries on molecular mechanisms controlling the circadian rhythm.>> To put it simply, they unraveled how our internal body clock works. That helps explain how people experience jet lag when their internal circadian rhythms get out of sync. And, also, has wider implications for disorders ranging from insomnia to depression to heart disease.

Otherwise, your body will finally, I guess, collapse because you will be very very tired.>> The pioneering work of the three scientists began with fruit flies. Scientists today are exploring novel approaches to new treatments based on such circadian cycles. Including establishing the best times to take medicines, and an increased focus on the importance of healthy sleeping patterns.

With research continuing into what happens if you constantly disobey your inner body clock.
