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.

With the 2014 Winter Olympic Games kicking off this week in Sochi, it may seem excessive to look ahead to the 2016 Summer Games in Rio de Janeiro. However, Brazilian officials are already under significant pressure for not meeting deadlines in planning the 2016 Olympic Games and the 2014 World Cup.
