Just as babies learn to crawl before they walk, anew line of robotsat the University of Vermont are able to walk by learning from successful movements.

Clocks pervade our lives, from the cellular clocksinside our bodiesto theatomic clocksthat underlie satellite navigation. These atomic clocks can measure time accurately to within one second in billions of years. But there could be a price to pay for this accuracy, in the form of energy. Our new experimentfound clocks that measure time more accurately consume more energy than their less accurate counterparts. This suggests nature imposes a fundamental energy cost for keeping time, and it may mean there’s a limit to how accurate we can make clocks....
