Houston, Texas provides a dramatic example that it's possible to make great strides in reducing air pollution. Our story yesterday talked about how that came about, but Houston still does not quite meet the federal smog standard. So, the question for the nation's fourth largest city is what's next. NPR's Richard Harris explores that question as part of our series Poisoned Places.

Brazil is a paradise for birds; the country has more than 1,700 species. Among them is the colorful toucan, a bird with an almost comically giant bill that can be half as long as its body.

There was great fanfare when the Mars Science Laboratory launched in November 2011, and again when its precious cargo — NASA's Mars rover Curiosity — touched down on the red planet in August 2012.
