Oral History Research Center Director Claytee White shares stories people have told her over the years about Las Vegas and explains the importance of recording these memories for historical record.

The American Southwest is running dry—literally. Lake Mead, the lifeline of Las Vegas, is shrinking at an alarming rate, and the city that defied nature is now facing one of its toughest challenges yet. But in true Vegas fashion, this city of reinvention is fighting back. From pioneering water conservation efforts to groundbreaking innovations like WAVR, a system that harvests water straight from the air, scientists and engineers are racing against time to secure the region’s future. Meanwhile, researchers are turning to an unlikely hero—cacti—as a potential solution for drought-resistant agriculture and even biofuel.

In the early 1600s, Galileo Galilee trained a telescope of his own making on Jupiter and spotted its four largest moons. Four centuries later, scientists are still seeking to understand exactly how those moons formed billions of years ago from a swirling disk of gas, dust, and ice that once surrounded the infant planet. Now, a new computer simulation suggests shadows cast by the inner region of that circumplanetary disk (CPD) may have created cold spots in the wispier outer region, creating the physical conditions needed for those materials to congeal into the moons Galileo spotted.

A lot of wild ideas get launched in Vegas and we’re home to the weirdest combination of architecture on the planet. But is there another Vegas, an even weirder version, that was never built? As the city waits to see if the A’s baseball stadium will break ground this year, co-hosts Sarah Lohman and Dayvid Figler sit down with UNLV history professor Michael Green to run through the wildest Vegas projects that were never built.

Steve Wynn, who once ran big casinos, wants the US Supreme Court to take another look at the 1964 New York Times v. Sullivan ruling. This decision has protected press freedom in the US for a long time. Wynn made this request after Nevada’s highest court threw out his lawsuit against the Associated Press (AP) and a reporter named Regina Garcia Cano. He claimed the media and journalist had damaged his reputation.

The impact of the construction industry is obvious during the daily commute. From roads and plumbing to power lines and even the grocery store — everything was previously a construction site, said Mac Bybee, CEO of the Associated Builders and Contractors in Nevada, or ABC Nevada.

For hundreds of years, people have turned to chocolate to boost heart health. Back in the 1500s, the indigenous Aztec people consumed cocoa as a drink believed to treat various ailments, including angina, a type of chest pain caused by reduced blood flow to the heart.

Valentine’s Day is nigh upon us. Soon there will be floods of flowers, chunks of chocolate, crowds of cards and maybe even substantial smooching. And what’s up with all of this kissing? Do all societies practice lip-latching? Do other animals kiss? Who was the first person who thought saliva swapping was a good idea?
