Modern humans dispersed from Africa multiple times, but the event that led to global expansion occurred less than 100,000 years ago. Some researchers hypothesize that dispersals were restricted to "green corridors" formed during humid intervals when food was abundant and human populations expanded in lockstep with their environments. But a new study in Nature, including ASU researchers Curtis Marean, Christopher Campisano, and Jayde Hirniak, suggests that humans also may have dispersed during arid intervals along "blue highways" created by seasonal rivers. Researchers also found evidence of cooking and stone tools that represent the oldest evidence of archery.

Nevadans will not see a total solar eclipse on April 8, but we will see some of it. The eclipse is expected to cross through the middle of America, stretching 13 states from Texas to New York.

Many airports around the world are applying AI, smart gate allocation and changing boarding methods to reduce flight delays. According to airports, in theory, cutting flight time by a few minutes may not seem significant, but this can help airlines save a lot of money. That also means services for tourists will be improved. Arriving a few minutes early can make the difference between catching up or missing your connecting flight, reducing the domino effect of delays and flights arriving more on time. The approaches being implemented by airports could help air travel operate more efficiently in the future.

Yesterday, the feds signaled their approval for a long-awaited agreement between the Colorado River states — collectively, the lower basin states (Arizona, California, and Nevada) will reduce our water use by 3 million acre-feet by 2026. The hope is that we’ll be able to replenish our crucial reservoirs, including Lake Mead, the source of 90% of our city’s water. But damming rivers to create reservoirs isn’t without problems. So… was creating Lake Mead in the first place a mistake? Today, we’re bringing back a conversation co-host Dayvid Figler had with UNLV hydrologist Dr. David Kreamer, who explains the history of Lake Mead’s creation and why reservoirs can be so essential for cities — but also controversial.

Every day, thousands of tourists flock to the Bellagio Hotel & Casino on the Las Vegas Strip to see the “Fountains of Bellagio,” a choreographed show involving light, music and more than 1,000 fountains shooting water up to 460 feet into the air. This week, a rare bird decided to join them.

Tourists circled the Las Vegas Strip’s impressive Fountains of Bellagio on Tuesday, taking selfies against the lush background of the resort. What they didn’t know was that they may have gotten an exclusive photo with Las Vegas’ hottest new celebrity — the yellow-billed loon, a migratory bird that has taken up residence in the property’s crystal blue waters.

Boarding a flight can be stressful as you navigate long queues, the mad rush to get bags into overhead lockers, and try to settle in within the short timeframe so the plane can leave on time.

An airline is set to split friends and family up in new plane boarding rules. One method that is being used by United Airlines splits up friends and families for the boarding process.

Getting passengers on and off planes in an orderly fashion can be a nightmare for flight attendants.

Airlines are trialling new techniques to shave minutes off turnaround procedures as a way to cut costs.

When Martin Schiller decided to launch his own company based off the research he did at UNLV, he picked Las Vegas despite the prospect of being one of only a handful of biotechnology firms in the valley.
