It was annual Senate retreat time in Washington this week, a moment when senators get away from the U.S. Capitol, free themselves of their staffs and daily legislative, office and fundraising chores, and try to gain some fresh perspective.

Harvard economist and health policy specialist David Cutler says getting the federal government's finances under control is all about health care.
They were some of the largest, hairiest animals ever to walk the Earth, but new research shows a big part of the woolly mammoth's diet was made up of tiny flowers.
