Egypt's President, Mohammed Morsi, was sworn into office one year ago this Sunday. Opposition groups plan major protests to mark the anniversary. Egyptians face rising food prices, fuel shortages and power outages in blistering summer heat.

Brazil is in the midst of a building boom as it constructs stadiums across the country in preparation for the World Cup it will host next year. In Sao Paulo, hundreds of workers are building a massive arena that will take many more months to complete.

Amanda Hodges, who heads the biosecurity research lab at the University of Florida, says that until recently, scientists saw about a dozen new bugs arrive in Florida each year.
