These weapons "will severely limit response times available to targeted nations and create a dangerous degree of ambiguity and uncertainty, at least in part because of their likely ability to carry either nuclear or conventional warheads," the board members noted.

If our body clocks are out of sync with our waking—and working—hours, shouldn’t we be tweaking our office hours to help improve our mood?“If our body clock is saying it wants us to wake up at 9:00, because it's a dark winter's day, but we're getting ourselves up at 7:00—then we are missing out on a complete sleep phase,” says Greg Murray, professor of psychology at Swinburne University, Australia.
