As you know, statistics can be twisted to mean anything we want. How about this computation? If every one of the 9 million tourists who visit New Orleans was to visit one of the 400,000 locals, you’d only have 23 visitors a year. You’ve probably had more folks than that over to watch a Saints game, right?

Two New Orleans revolutionaries, Patricia Maher and Lowry Curley, join Peter Ricchiuti for a fascinating look at a New Orleans that seems to be changing faster and more radically than ever.

A professor at the University of New Orleans has received a grant to study marshes. The research will compare wetlands in Louisiana with those on the east coast.

An effective and non-addictive painkiller has been developed by researchers at Tulane University with the Southeast Louisiana Veterans Health Care System. The new compound has been in the works since a 1997 discovery of a brain receptor.

Extensive data collected by oil and gas companies along Lake Pontchartrain and Lake Borgne will be used by researchers at the University of New Orleans studying sea levels on the Louisiana coast.

The Gulf Intracoastal Waterway is a shipping canal that runs over 1,000 miles from Texas to Florida. But in Lafourche Parish, it’s become more than an industrial throughway. It's a battle line against coastal erosion, and experts are determined to keep saltwater out of it.

The international climate talks wrapped up in Paris this weekend as the United Nations parties finalized an agreement to stave off climate change. The terms of the agreement call for limiting global temperature rise to around 1.5 degrees Celsius, well below the initial goal of 2 degrees.

WWNO’s Tegan Wendland talked with Bob Thomas, professor and director of Loyola’s center for environmental communication, about whether it will make a difference.
