Argentine-born Pope Francis knows it’s not enough to be the first Latin American pontiff. He also has to make that mean something.

So far he has. He’s condemned the region’s still epic inequality, he's tried to mediate the unholy mess in Venezuela – and most famously he's brokered a rapprochement between the U.S. and Cuba that could thaw a century of bitter mistrust between Washington and Latin America.

Chile’s northern Atacama Desert is arguably the driest place on Earth. In some parts of it, rainfall has never even been recorded.

Besides the horrific carnage inside Port-au-Prince, one of my most vivid memories of the 2010 Haiti earthquake is military helicopters idling out in Port-au-Prince Bay.

From the bridge of the Navy aircraft carrier U.S.S. Carl Vinson, I watched H-53 and Seahawk choppers waiting for rescue and relief supplies that seemed agonizingly slow in arriving from U.S. and other foreign aid sources. International coordination, in fact, felt as wanting in those first few post-quake days as the food and medicine.

Researchers have discovered the largest virus ever, and they've given it a terrifying name: Pandoravirus.

In mythology, opening Pandora's Box released evil into the world. But there's no need to panic. This new family of virus lives underwater and doesn't pose a major threat to human health.

"This is not going to cause any kind of widespread and acute illness or epidemic or anything," says Eugene Koonin, an evolutionary biologist at the National Institutes of Health who specializes in viruses.
