The seven states that share the Colorado River did not meet a deadline for an agreement on water cutbacks. What is next for this vital water source in the West?
When you picture a desert, you probably imagine a vast, empty landscape far from any water. But surprisingly, some of the driest places on Earth lie right beside the ocean. Both the Atacama, in Chile, and the Namib, in southern Africa, stretch along coastlines. So how did these extreme deserts form in places bordered by so much water?

Red Rock Canyon draws climbers from around the world, offering towering sandstone cliffs just minutes from the Las Vegas Strip. However, after rainfall, those iconic red walls can be more dangerous than they appear — even when the rock looks dry. According to Zach Perzan, an assistant professor of geology at the University of Nevada, Las Vegas, the sandstone at Red Rock — known as Aztec sandstone — is made up mostly of quartz grains held together by a relatively small amount of natural cement.

Gold briefly topped $5,100 per ounce for the first time Monday, and as the fifth-highest gold producer in the world, this is good news for Nevada. With gold hitting a record on the global market, for Nevada, this means more jobs, more tax revenue and more gold exploration, according to mineral and mining experts.
Humans are some of the greatest builders on the planet, but we’re not the only ones. Beneath the ocean, some unlikely creatures build breathtakingly intricate structures with a variety of clever techniques and materials. Underwater homes serve many purposes: they shelter offspring, offer refuge from predators, and in some cases, support entire ecosystems. Some of these creatures even open their homes to other species. And some can even be kept in a home aquarium, where you can watch them build their homes.

What if Howard Hughes, Hoover Dam, or the family-friendly era had never arrived to change Sin City? It’s time to go into the Vegas multiverse.

For years, scientists have asked whether fossils record how ocean ecosystems actually worked, not just which species were there. A new study answers that question with a careful field test along the North Carolina coast.

Lake Mead is projected to reach some of its lowest water levels ever recorded by 2027, raising concerns about the future of the vital water source. Tourists and locals alike are witnessing the stark changes in the lake's water levels, with the lake currently running 7 feet lower than it was in 2023 and 2024.

With gold hitting an all-time high, it begs the question, is Nevada really the gold state? The price for gold, which is set on a global market, closed at $3,383 per ounce on Friday, a good sign for Nevada. In fact, if Nevada was a country, it would be the fifth largest gold producer in the world, behind China, Russia, Australia and Canada.
Researchers explain what we know about the potential for water and life on Mars and what we might learn from analysis of returned samples.
Another summer, another Lake Mead update: And this year, it's not looking great. Our snowpack gains this winter were pretty dismal, and the National Weather Service recently even lowered their projections for Lake Powell, whose upstream levels affect Lake Mead's. In light of all this, we're bringing back a conversation that co-host Dayvid Figler had with UNLV hydrology professor David Kreamer. The creation of Lake Mead was not without its costs — so was it worth it? And what happens if we use Lake Mead up?
