Over-80 cardinals, who cannot vote in the conclave, are lashing out at the Francis papacy, calling for change of course. "Give back the church to Catholics," a 94-year-old Italian cardinal said.

An Italian cardinal who was convicted of embezzlement and fraud said on April 29 he will not take part in the secret conclave to elect the new pope that will be held beginning on May 7 in the Sistine Chapel following the death of Pope Francis.

Many continue to mourn the loss of Pope Francis, who passed away last week on Easter Monday at 88 years old. A passenger's mobile device was lodged in a seat and caused "an electrical smell," prompting an emergency landing to remove it.

Last year's Oscar-nominated movie Conclave has become a big streaming hit in the wake of the death of the Pope. But how accurate is the film?

While any baptized Roman Catholic male is eligible, only cardinals have been selected as pope since 1378. The winner must receive at least two-thirds of the votes from those cardinals who are under age 80 and thus eligible to participate in the balloting.

For more than 750 years, strict rules have guarded what cardinals can and cannot eat to prevent hidden messages stuffed inside chicken, ravioli and napkins.
